Too bad it was too early for any taxidermists to preserve their skin. I suppose they were already dying out when we discovered them. It's a nice dream to think that maybe one of these species is still alive but it's impossible.

I'm interested in our relationship with extinct animals. I mean things like works of art created when they were still alive. Pic related a painting of some exotic birds including dodo. Early 17th c.

Just because animals look alike, doesn't mean they are anywhere near related.

Man too many too count. As an obvious answer i'd say ice-age era animals, like the cave bear, dire wolf, irish elk, wooly rhino, wooly mammoth, sabre tooth, bison antiquus/latifrons, cave lion, etc etc...
Also the crazy south American megafauna like terror birds, megatherium, doedicurus, glossotherium, toxodon... And from australia and surrounding islands/ landmasses like the short-faced kangaroo, moa, haasts eagle, diptrodon, megalania...
Others i'm not sure on where and when they lived would include paraceratherium, argentavis and other terratorns, ellephant birds, colossochelys atlas, argelon, deinosuchus/sarcosuchus, titanoboa, lyvitan melvilei, megalodon, meganeura, arthropleura, brontoscorpio, pelagornis, ammonites...
As i said, too many to count. And i havent even gotten to the dinosaurs yet.

>Leptictidium was a bipedal tenrec that nests as a sister to land (stem) whales and aquatic whales (Fig.3).
>On land, Leptictidium might have hopped, like a kangaroo. Or maybe not.
>In water, Leptictidium let its legs extend backward as it undulated its supple spine and greatly elongated robust tail (Fig 1) in the manner of sea otter (see video). Of course all four legs contributed to propulsion and steering.
>Over time, the longer tail and lumbar region became more efficient, reducing the need for drag-inducing hind legs. The pelvic connection was already loose at this stage. So were the leg joints.
>Leptictidium was preserved with a complete pelage of thick fur. That disappears, of course, in whales.

I was shocked to find out the Eastern 'mountain lion' was not a real animal. I know a man who was attacked by one, and had the scars to show for it. I'd like to see how scientists would explain his scars given their appearance. I've also know people to give multiple accounts of the beast, and the appearance does not match up with a cougar. Yet, there are no large cats that exist in our forests. I did once see this fluorescent orange bird with a tiny head, long beak, and huge round body sitting at the root of a tree. I told people about it, no one believed me. Then my friend saw it walking down the same road and came back in a panic going, 'I saw the damn orange bird!' Later, 3 of my friends were walking with me while I was telling them about it, and they called me crazy. On the walk back, the fucking orange bird was sitting there. I cannot figure out what this bird is, it doesn't match any known species.

A scientist working in the Amazon related to my family told me that barely any biologists even work in the temperate rain forest pockets out the Southern U.S., and no one knows what animals really exist.

>>2291395
because we would be utilizing tame versions of whatever these beasts are in place of caterpillar machines

Trying to limit myself to (mostly) reasonable stuff like dodos and lizards. The crocs, turtles, and monitor are never gonna happen, though. The dodo probably has the best chance to be cloned back; relatively small size, very iconic (everyone knows what it is, so it's easy to financially support cloning), went extinct very recently, enough genetic material (I think?), somewhat close living relative in the Nicobar pigeon, and native to a small island so we could potentially reintroduce them at some point.

>They were at best sauropod 'hide snackers' to hunters of juvenile to adolescents sauropods...

Tyrannosaurus were generally overall more efficient killers
1. Significant vision superiority (among dinosaurs in general, including modern eagles); all carnosaurs had very poor vision and mainly relied on sound.
2. Leagues better sense of smell.
3. Equal to better hearing; rexes can even hear low-frequency sounds.
4. Proportionately and overall larger, more advance brains.
5. Generally more robust durable bodies, meaning stronger 'pound for pound' and less likely to be injured.
6. Proportionately longer, stronger and sturdier legs and hip designs.
7. Overall stronger, more lethal bites. Carnosaur bites hurt, but a single tyrannosaur (esp. t-rex) bite would greatly maim to instantly kill their opponents.


Carnosaurs likely did not advance much because of their easier targets (juvenile to adolescent sauropods), while in gangs. Tyrannosaurus generally had to engage in more combat with their armored prey; sauropods in generally were more rare around the era of tyrannosaurs. Heck, they even had to watch their backs from other cannibalistic rexes.

8. Tyrannosaurs also tend to have strong signs of rapid healing and powerful immune-systems, based on specimens surviving multiple injuries that should have otherwise killed them; most extreme cases cone from t-rex and gorgosaurus.

>Not knowing how to greentext
>factual factors

1. This only applies to the tyrannosaurs with binoc vision, which was not the majority
2. wut? Literally no proof.
3.Holy shit, the reason why T. rex had all these incredible abilities that other dinosaurs seem to lack is because rex recieves more attention from scientific studies than any other theropod by several orders of magnitude.
4. More reptilian =/= inferior. Compare a crocodile or a monitor lizard's intelligence to a pigeon's.
5. This is true with rex, not true for almost any other tyrannosaur. Rex had to sacrifice his curosoriality in order to achieve his level of robustness.
6. Longer limbs =/= better. Faster? yes, but both had there advantages. There is nothing to suggest there legs and hips were stronger or sturdier.
7. Overall, yes. However, just because Carcharodontosaurus didn't have "muh high bie force bone crushing!!!" didn't mean it couldn't clamp its jaws around a limb or neck and shear all of the skin away, leaving nothing but exposed bone.
8. See 3.

Now, lets get to what Allosaurs do better, I am not looking at them in terms of killing capacity, but as animals as a whole.
1. Agility- the longer tails of the carnosaurs such as allosaurus and neovenator, would lead to a greater degree of balance control and faster shifts in posture and jumping. You won't here about this alot because again, most paleo people couldnt give 2 shits about carnosaurs because "muh feathered tyrants".
2. Arms. I can think of maybe three different tyrannosaurs that had fore arms developed past near vestigial. Jaws aren't the only instrument of death, mate. See pic related, I've personally examined the OMNH Saurophaganax claw and I've never seen a more impressive tool of wanton suffereng.
3. The glorious headcrests very much add to the aesthetical appeal and social dynamics of the animals.
4. Adaptabilty. Leaving aside the ancestral tyrannosaurs, carnosaurs adapted into every predator niche on the planet.

1. :..As in the part about rivaling(more like exceeding)even eagles...Otherwise it implies truth that the general family of tyrannosaur do indeed have better vision than most dinosaurs, and definitely in comparison to the very poor vision of carnosaurs
2. You mean other than even 'pro primary scavenger' theorists usually using tyrannosaur above average sense of smell to support their claim. Hell, most people know them for their sense of smell than even their extraordinary vision. How new to this are you?
3. We have the back portions of skulls and/or brain cases of carnosaurs like allosaurus and giganotosaurus: hearing about the same, if not a bit worse than tyrannosaurs
4. Which would either way be much lower for the carnosaurs...
5. They were still 'pound for pound' more heavily built, just not to the more insane degree as t-rex(the overkill heavy weight bodybuilder in their group)
6. The pubic bone and typical femur thickness tend to suggest otherwise
7. Maybe to animals much smaller than themselves, but their teeth are simply not proportionately long or strong enough for that task. Plus, they cannot gyrate their skulls while biting for additional damage due to their weaker teeth and much softer upper-pallets
8. Some truth in this case, but does not tale away from the sheer scale of efficiency tyrannosaurs show


Allosaurs
1. To some degree, but dinosaur tails were generally built stiffer than mammals, especially with leg muscle attachments
1.5. The jumping is mostly a speculative myth. They (as heavy or heavier than giraffes) would simply be overall too heavy with risk of death being high
https://www.youtube.com/watch?v=me0d9YGbWAc
2. Designed to grasp palm to palm, not swipe like a cat;meant to help with kills, not really cause them
3. Headrests are not at all beneficial for killing, just status among their own kind
4. Most, and only because the southern continents were in fact separated by sea;otherwise abelisaurids would have also been out competed

You keep taking facts about Tyrannosaurus rex and applying them to the rest of tyrannosauroidea.

1. See above, some tyrannosaurs had binoc vision. Most didn't.
2.See above
3. Nothing to suggest this.Post source.
4.What?
5. No, not really, see pic related
6.Post source.
7. Yeah, no. Carch's teeth were weaker in the same way that a knife is weaker than a mallet. The Carch clans jaws were designed to slash and shear as much flesh away from bone as possible. And considering their primary food source would've been sauropods, I think they would've worked quite nicely on animals there own size.


1. Stiff tails= more agile. That's why raptors had static tales.
1.5. I think you're seriously underestimating large animals here. Giraffes cant jump because theyre animals with no leg muscle walking on stilts. If you take a bipedal animal with gigantic thighs for shock absorption and a long tail for balance, that animal would have less of a problem leaping to climb the flanks of a sauropod.
2. You're confusing this with raptors. Allosaur forearms were far too muscular andthere claws far too large to be used for just utility. That Saurophaganax claw was over a foot long and had gigantic flexor tubercles for muscle attachment.
3. Did you read what I said about how I'm looking at the animals as a whole and not just about capacity fro killing.
4. There were tyrannosaurs in the south, and they never outcompeted the abelisaurs. What I meant to say in my post was that aside from the ancestral tyrannosaurs, the allosaurs adapte into many more varieties than their tyrannosaur counterparts. There are essentially two types of tyrannosaurs. Cursorial predator with bone crushing bite and robust predator with bone crushing bite. Allosaurs adapted to every conceivable predator niche on the planet.

>Considering the length was about the same, the torosaurus should be taller esp with its cocked up s-shaped neck
1. Predatory coelurosaurs in general had superior binocular vision, with tyrannosaurs like daspletosaurus, tyrannosaurus, nanotyrannus(assuming it is its own species) with high scores rivaling eagles and hawks
http://www.bioone.org/doi/abs/10.1671/0272-4634%282006%2926%5B321%3ABVITD%5D2.0.CO%3B2?journalCode=vrpa
Studies also show gorgosaurus, alioramus, and lythronax had binocular vision, esp compared to very low carnosaurs standards.
2. Uh, is that inaccurate image supposed to debunk tyrannosaurs famously having better sense of smell in comparison to carnosaurs? It's pretty much tyrannosaur sensory 101...
3. Aside the fact we know tyrannosaurs in general seem to also value hearing to the point where they could hear low frequency sounds...
4. Tyrannosaurs would still have proportionately and overall larger brains, regardless if at the reptilian standard
5. Grossly incorrect
6. Mainly true for larger tyrannosaurs
7. No, that is mostly false. They were really just meant to bleedout prey over a long extent of time, in gangs. Their teeth are still overall all too weak and generally not very proportionately long, especially when adding gums.
It will definitely hurt, but it would not kill quickly unless the target is much smaller than itself; contrary to tyrannosaurs, which would make short work of animals even larger than themselves (to certain degrees)

>Pt.2
Allosaurs
1. That depends, and I and not particularly sure to the extent of this case
1.5. Giraffes actually have strong leg muscles, powerful tendons (which allow impalas and deer to jump to high and far), and have four(4) long powerful legs. Theropods only have two legs (less legs to land on) and dinosaurs like allosaurs had proportionately lighter frames, meaning higher likelyhood of being injured esp with their weight would be too significant (allosaurs typically weigh as much, if not more than the average giraffe)
Seriously, it was merely a speculative theory
2. First off, it was dromaeosaurs that had more developed and proportionately larger arms with more wrist flexibility (carpal bones; allosaur’s were nonexistent, meaning permanent fixed ‘clapping’ position). Even your description of allosaurian arms match perfectly to the use I had just addressed (grasp palm to palm to aid in killing, not really to cause them), esp the claw shape; even better if the prey is shorter to grasp them better.
3. Did you forget that the primary point of this conversation/debate is about comparing and contrasting the two general families to judge which were more efficient killers? This is why the headcrests did not even need to be mentioned
4. Those were supposedly very different kinds that may have branched more from dilong. They were mainly more like the illusive shadows of their tiny ancestors and likely preferred smaller prey. Some theorize that they separated from other tyrannosaurs and evolved into what we consider megaraptoran (megaraptor and australovenator), which people cannot seem to completely agree on their origins; I personally do not know for sure either.
Abelisaurs at that time were more like tyrannosaurs than the supposed lighter framed, likely more docile, illusive versions that might not even be tyrannosaurs in the first place.

Thats an Epanteiras sized Allosaur with a gorgosaurus. Many Tyrannosaurs had that long legged fragile build and that reconstruction is from Scott Hartman who makes anatomically precise diagrams for a living.
No, its Tyrannosaurs rex sensory 101. When I see above, I meant see what I said, not the image, which is very accurate by the way.
Again, there is nothing to suggest allosaurs didn't have these same capabilities, besides the fact that no one has ever bothered to study it.
Again with the brains, no. The only studies have concluded that tyrannosaurs have more avian brains while allosaur brains were more reptilian. Which as you can see by pic related, does not mean less intelligent.
Smaller allosaurs likely had sturdier legs than tyrannosaurs, drop the point.
That is not false. The weak allosaur jaws is a meme completely made up by tyrannofans with no scientific support. The consesus among scientists is that allosaur teeth weren't designed for crushing so they didn't need to be deep or long. Just sharp. Very very sharp. I gave myself a cut on a carch tooth I was handling. Yes they were meant to bleed out prey but you are seriously underestimating how long it takes. The Giganotosaurus didnt evolve 6 ft jaws with razors to slowly watch prey bleed out.

1. Giraffe's leg muscles are only strong relative to the smaller animals of today. Allosaurs lighter frame probably HELPED with the feats of agility.
2. I fail to see your point in the dromaeosaurs. It was indeed the dromaeosaurs that have undergone a revision in the utility of there claws, I have read no such paper discussing this for allosaurs. You're right they were probably used for grasping prey, but the probability of one use does not rule out another. Allosaur claws would likely cause grievous wounds just as deadly as a bite.
3. That may have been the point of the discussion for you, but I never said that.
4. No, there is evidence of other tyrannosaurs on the southern continents, but the evidence was sparse. Why? (Hint: its because of the abelisaurs) I tend to believe Currie on these matters as he's been doing it longer that the Megaraptorans were carnosaurs after all.
Pic related: Is that a tyrannosaur you say? Nope just a classic example of allosaur adaptability.

I'm not interested in your fanwanking. My interests are in Ornithischia and Sauropods, Hadrosaurs in particular. I just remembered the article.

lastly direct mass may mean little in a fight anyway, if you were to go off mass alone most theropods wouldn't be able to do jack shit to large hadrosaur.

There were only ever two specimens, which may have been two different but highly related subspecies.
All we actually have of carcharodontosaurus in total is a skull and teeth from the second (which seem much lighter built that that of giganotosaurus). Considering the original specimen also included a partial skeleton and was indeed considered to be very light for its size of 4.6tons at 39ft, a larger 44ft would not be too dramatic in comparison.
According to Gregory S. Paul, Carcharodontosaurus iguidensis is actually 10m(33 ft) and 4t(4.4 short tons) Keep in mind that both specimen's skulls being estimated about the same size...

I cannot say that I agree with all of those, but it stands with reason that carcharodontosaurus was a lighter built animal than giganotosaurus. Thus it would realistically weigh as much (arguably slightly less) than a giganotosaurus.
Pretty much anyone with basic facts about these two dinosaur would know giganotosaurus was about the same size to slightly larger in terms of length and hip height. Unless you have been playing too many videogames and treating them as factual.

hadrofag again, I don't care about the dick waving contest. I couldn't give less of a shit who would win between a Rex or a Giganotosaurus or any other large theropod for that matter.

In fact who the fuck cares beyond you? Reading the thread it seems you got buttmad that some guy said he wanted to see a giant Allosaur.

Plus Sue seems to be an exceptionally large individual (from what we know), not the norm and regardless of that it still put an average 6 to 8 tons not to dissimilar to the studies 5 to 7 ton range for Acro.

>he doesn't use sci-hub
>he cant read technical papers
>he didnt read the part where the authors outright disregard their largest estimate for Acro because they thought the build was to infeasible.

Are you underage or something?

Stop fanboying over T.rex and glorifed cockfights and realize there is more to dinosaurs than that.I mean Tyrannosaurines as a group are intriguing in that they came out of nowhere around 80 to 70 mya and rose to become the apex predators in Asia and North America after the extinction of dinosaurs like Acrocanthosaurus and Siats. and the other Allosaurs and Tyrannosaurioids of Asia like Shaochilong and Yutyrannus.

If you study size distributions for gigantic theropods for which more than a couple specimens are known,

you find that they match snakes and crocodiles distributions. Animals that don't stop growing during life. Which is to say, neither of the animals the butthead is arguing about actually had an "adult size."

Sue may or may not be an outlier. We may or may not find larger specimens of allosauroid in the future. We probably will. But the argument is useless because these animals didn't have a single size, and we almost certainly don't know how big they got.

but they aren't comparing Allosaurus....

>>2315337
Yeah I guess for that single species of A. fragilis. But they were talking about giga and carch which have 2-3 specimens a piece compared to 40- something for Rex. Hell, any large predator competitive with Rex in size have a specimen number that you can count on one hand. All I'm saying is that Rex has the luxury of using Sue (a fucking monster) as their model for size while giga, carch, Saurophaganax, etc are using an average member.

>>2315371
With Allosaurus don't forget A. amplexus, It was approaching the size of T. rex.

>>2315403
Aka Epanterias. I've personally looked at the bones for A. fragilis, E. amplexus (dubious as hell) and S. maximus (significantly less dubious but still iffy) and Impo they're all are at least different species (prob differet genera too). You dont get that kind of size differences between animals of the same species especially when an average is so well represented at 28 ft. 2.5 tons and the others being literally 100% larger and no transition forms.

>>2315441
>You dont get that kind of size differences between animals of the same species
sure you do kiddo.

Like I said, snakes and crocodiles grow to almost triple their average adult size.

stop pretending to be a paleontologist, you're an idiot.

>>2315461
Again, no transitionary forms. There are no 30 ft or 35 ft. allosaurs, just 28 fters and 38+ fters. Leads me to believe that they're probably different species if not genera. We really don't know shit about dinosaur growth so dont presume to apply a conclusion of a study or two to all of theropoda.

Ooh an almost 40 year old reference book on allosaur bones. (I'll read it regardless, but I'll take the current ideas over a book written 10 years before the Dinosaur Heresies was written. And I have read Chure, but his line of thinking got Saurophagax classified as A. maximus. Guess what its currently classified as.

Theres not one right idea in paleontology, the whole science is replete with issues with no strong consensus. Just because I said something different than your 40 year old book, doesn't mean I don't know what I'm talking about.

>>2315492

>>2315471
>There are no 30 ft or 35 ft. allosaurs, just 28 fters and 38+ fters.
Let's run through that by the numbers. Madsen states in his monograph that he found at least 44 Allosaurus based on the number of left femora found.

He lists their top length at 12m. He lists the largest Allosaurus he knows of ("Epanterias") as having a length of 13m. (Page 5 of his A. fragilis monograph).

His table of femur lengths gives a largest measurement of 910mm. This gives us a ratio of Femur Length to Body Length (FL:BL) of 910:12000, or 1:13.3333....

Applying this ratio we find that an Allosaurus with a body length of 28-38 feet would have a femur length of 640-869mm. Madsen lists 34 theropod femora, of which 30 are Allosaurus fragilis. 7 Allosaurus femora fall between those sizes. Meaning of his sample over 23% fell into the size range you say doesn't exist.

It is possible his size estimates were wrong, but since they are the same ratios used to estimate "Epanterias" and Saurophaganax sizes, that just means if Allosaurus is estimated smaller so are the others. Saurophaganax and "Epanterias" would shrink too. "Epanterias" is the largest Allosaurus specimen known from a femur, and its femur length is only 6% larger than the largest Allosaurus fragilis Madsen described. (910mm vs. 973mm).

So we find that not only do Allosaurus exist in the 28-38 foot range, but they make up almost a quarter of known specimens.

And as Dr. Holtz is fond of pointing out, all of those are juveniles according to bone histology. Not a single one of them from the smallest to the largest has ever been found with the skull bones fused. (braincase fused to dermatocranium) These animals, including the 43 footers, weren't even adults. We expect to find much larger Allosaurus fossils someday.

Did anyone say trilobites yet?

>>2315619
because the holotype and all material assigned to "Epanterias" verifiably belongs to Allosaurus fragilis.

The species was originally erected based on size. When Cope described it, it was 20% larger than the only good Antrodemus (=Allosaurus) material. Back then paleontologists imagined dinosaurs to have an adult size similar to mammals, so finding an Antrodemus that was 20% larger seemed a good reason to erect a new species. Also Antrodemus wasn't well known and the parts of the two holotypes didn't overlap much. So Cope wasn't able to compare his "Epanterias" to similar parts of Antrodemus.

Now we know they're the same thing, having found close to a thousand of them. And we know that while "Epanterias" is one of the largest specimens out there, it's falls within the normal size range of Allosaurus. Everyone that has examined "Epanterias" recently has agreed that it's Allosaurus fragilis with the exception of Bakker. He was trying to declare some "Epanterias" material he found up by Ft. Collins, CO a neotype. This was quite a while ago and afaik he never published it. Presumably it turned out to be Allosaurus fragilis.

What the hell are trilobites supposed to be anyway? Crown arthropods? Stem arthropods? Another phylum?

>>2315902
Basically, we don't know exactly how to classify them at the moment. I suppose they could be a crown arthropod, but they're apparently unrelated to other groups.

>>2315902
Giant aquatic woodlice.

>>2315902
sea cockroaches

>>2316074
does that make them distant ancestors of the Turks?

>>2315902
Pretty much agreed to be within the crown, usually as the sister to Chelicerata, although some studies on well-preserved agnostid trilobites claim sisterhood to Mandibulata, but agnostids are weird anyway so who knows for sure.

>>2316650
Is an Insecta=Chelicerata+Mandibulata monophyletic? If so, what's its sister group?

>>2316782
Hexapoda (including Insecta) is nested within Crustacea (which is often renamed Pancrustacea). Pancrustacea is sister to Myriapoda (centipedes et al.) to form Mandibulata, which is sister to Arachnomorpha (Chelicerata + Trilobitomorpha) to form crown Arthropoda (=Euarthropoda). There are plenty of odd little extinct taxa mixed in here and there, and some just outside the crown that we would call arthropods if they were alive today.

Carnosaurs were very lightly built than most large dinosaurs. Even allosaurus was named for its very large trabecular cells compared to other theropods; hence why it was called 'fragillis'.
