I'd say the Dakota raptor. It's smaller than the Utah raptor, but it's not too small, bigger than a human. It's feathery body probably looked cool AF too.

The Spitter

There isn't really any evidence that it spat in defense or even had a frill like a frilled-lizard. Jurassic Park made it up as a way to demonstrate how little we may know of their biology, due to just working with bones; not just to make it simply cooler.

I seriously used to believe they were semi-aquatic herbivores that mostly fed on aquatic leafs.

https://www.youtube.com/watch?v=kmsfAm3NOZY
Clip from 'Land Before Time'. Long story short:
The adult parasaurolophus is a mother whom adopted a mentally challenged stegosaurus named Spike, after her child found the lost egg long ago. A herd of stegosauruses wanted to take Spike to "raise him with his own kind". He fell in the ice and could not be saved by the stegos, because they cannot swim. Parasaurolophus being a semi-aquatic animal (based on outdated information, as with all the dinosaurs) jumped in and swam to save spike, which lead to the other stegos tolerance and acceptance that she truly cared for Spike and was fit enough to raise him.
Although by today's information, parasaurolophus was probably no better at swimming than stegosaurus...
Nowadays, parasaurolophus are described as having dinosaurian hoofs and were entirely terrestrial.

Speaking of odd tyrannosaur derivatives, megaraptorians were more related to dilong. Unlike later tyrannosaurs, they generally had less powerful skulls, larger claws, less robust bodies, and likely preferred proportionately smaller prey.


Its skull does not seem to be for fish as may be the case for qianzhousaurus/Pinocchio-rex.

>>2253230
That is the usual arrangement found in dromaeosaur fossils, although there are others such as having long feathers all the way down the tail as seen on Zhenyuanlong.
The fans and stuff probably served a purpose such as display (for mating as well as intimidation) and/or aerodynamics for running (ostriches do this) and gliding (in the case of microraptorines and possibly juveniles of others)

Some maniraptorans such as Caudipteryx or Similicaudipteryx had a fan of feathers on their tail. Out of dromaeosaurs, at least Microraptor had tail feathers too. So people assume their relatives may have had them as well.

Pic related, Zhenyuanlong tail feathers. Note that this is the largest dromaeosaur found so far with feathers, being similar in size to Velociraptor.

Velociraptors have been found with quill knobs in their arms, and now we know thanks to Zhenyuanlong that this confirms the presence of substantial wing feathers. The quill knobs found in Dakotaraptor therefore imply that even massive dromaeosaurs had wings.

Well Killarysaurus Rex was able to defeat Berniesaurus Sanderpteryx, which seemed to be a derivative smarter cousin to Trumpasaurus; almost the same, but different. But Trumpasaurus is a much more aggressive beast that does not care what people think of it; though to its weakness.

Also, Killarysaurus Rex is more of a sneaky killer with a weak resistance to illnesses. But is clearly smarter and more clever than Trumpasaurus. Killarysaurus Rex also have support from a hovering flock of quetzalwallstreetatlus swooping in her defense.
I don't know, but it would be one hell of an epic battle.

The skull and even claws for megaraptor are more akin to coelurosauria. Megaraptorians were pretty much adaptive and oversized dialogs, which are derived from primitive tyrannosaurs.
Plus, they came into existence long after the extinction of carnosauria, meaning even less likely connections.


Allosauria was just the default label for most very incomplete dinosaurs.

QUESTION
Is dilophosaurus some how related to spinosaurus?

The way the tip of the snout interlocks is very similar to the otherwise unique design of spinosaurs (suchomimus, baryonyx. and even spinosaurus). This design seem more perfect for catching slippery fish than anything else.


Could it be one of the earliest forms to spinosaur origins?

>Nostrils go high and more back, snout is proportionately long, crested head(although spinosaurs have proportionately smaller crests) , tip of snout interlocking and is shaped
Perhaps dilophosaurus is related to spinosaurs as megaraptor is likely related to tyrannosaurs.

As in dilophosaurus might be a derivative of primitive spinosaurs. I say this because dilophosaurus is double crested, while spinosaurs tend to have a single proportionately smaller crest. Meaning at most, it may be related to the common ancestor that lead to later more established spinosaurs

Not according to Coria and Currie, who published the most recent cladistical analysis of megaraptora. Yes they shared SOME features with Coelurosauria, but apparently they lacked others as well and the shared traits may just be an example of convergent evolution.

The claws alone pretty much contradict supposed megaraptorian relations to carnosauria. In fact they resemble more like those of therizinosaurus, which may be more closer to each other than some might think; therizinosaurs possibly deriving from this branch of tyrannosaurs.


The skull resembles too much like dilong's, which was a kind of primitive tyrannosaur.

Also, they existed long after carnosauria, meaning even less likely connections.


______


At best, megaraptorians were coelurosaurs that may arguably have had some carnosaurian traits (very few and not very significant in comparison), not the other way around.

All traits can be used, especially when the traits are so unique to typically one branch or clade of theropods.


It is a striking near perfect match how the claws (what it is named for) actually seem like the same distinct kind and shape as coelurosaurian therizinosaurus. Almost as if it is this is the branch of tyrannosaurs that therizinosaurs derived from; derived from carnivores.
They resemble very little to nothing in carnosauria.


The head (one of the most unique areas) is more (even if not necessarily a tyrannosaur) coelurosaurian.


The time of existence seem to match more with the diversifying of coelurosauria than carnosaurs

I think this is a case of agree to disagree, yes they may have had coelurosaurian features, but they lack key derivative traits of coelurasaurs as well. Consider that possibly the examples of convergent evolution may just be the same responses in different families to the shifting climate and prey selection. Pic related, for example, is a confirmed carnosaur, but looks almost identical to a Tyrannosaur.

not at all.

the first Australian theropod found consisted of a single astragalus that's identical to that of Allosaurus fragilis.

it was in fact named Allosaurus sp. until more material turned up. It was originally thought that Allosaurus survived on the Australian landmass long after it went extinct in the US and Portugal.

It could be convergent evolution, but it is too much of a coincident. In addition to similarities, dilophosaurus predates all known spinosaurids, so it might actually be related to one of spinosaur's earliest ancestors. Thus making it a distant cousin, if true.

>>2254189 Makes good points.
The general shape and design of the premaxilla, maxilla and denary align too similarly.

The premazilla is especially suspicious, as for it is shaped like that of spinosaurus with the same signs of waters sensors or whisker marks.


I just do not know.

>>2256675
>I just do not know.
then consider for a moment that crocodiles have exactly the same facial shape as do Alligator Gar.

do you think Dilophosaurus, Spinosaurus, crocodiles, and alligator gar all got their facial shape from the same ancestor?

or is it possible that the shape just happens to be good for catching fish and other little critters in the front of your mouth?

you decide.
paleontologists already know the answer.

First off, croissants aren’t a line, they are shaped like a “c” they are nothing like a line, they aren’t even straight. So why do you want to “croissant the line” there is no line. Croissant is not a line and it never will be no matter how much you push these straight ideals onto it, it’s really not right at all.
And SECONDLY, do you really know chibatta dough has to do? DO YOU KNOW WHT FREAKING CHIBATTA DOUGH HAS TO DO?!! I don’t freaking think so. It has to sit in room temperature for about an hour and a half until it’s doubled in bulk. It will be full of air bubbles but that’s okay. IT DOES NOT HAVE TO BE USED FOR YOUR TRASHY PUNS. I’ve read the recipe. Have you? Apparently not.
And you want to fight in Rye? The unicorporated county in the Gila county of Arizona? Because in my personal opinion it is SUPER rude for you to expect your opponent to drive all the way out to Rye just to fight YOU. I just can’t believe this. Oh my god

>>2258405
he's right.
it's not bracketing.
for bracketing you need both ancestors and descendants of the bracketed animal.

you could also use ancestors and sister taxa.

if you can't manage that then you could use two or more sister taxa, or sister taxa and descendants.

the problem with rex is it has no descendants and none of its sister taxa are known to have feathers.

so technically it's not bracketing. It's a decent supposition that if its ancestors had feathers it did also, but it's not bracketing.

also the reverse is true- if it didn't have feathers then those feathered dinosaurs probably aren't its ancestors. This will be the view in a decade or two. People will likely find Yutyrannus and Dilong aren't related to Tyrannosaurus.

It's not impossible, but it is also not very likely. Some wild lions do it with antelope species for example, but they are very rare cases and the fawn/calf usually end up eaten by other lions.

Even if the rex adopted the baby and no other rexes were there to kill it, at some point the trice will no longer even be a juvenile. Once the trice reach a certain age, it might just turn on the trice because of instincts; the trice is no longer so vulnerable, but it an editable food source it was evolved to target.

But who know, maybe at worse they will simply part ways and might even recognize each other's scent.

The rex probably would not care for it too long.

Here is a tiger that temporarily adopted a fawn, because her hormones made her more motherly. She eventually just let it go, but at least did not try to eat it afterwards.

This animal used to be known as an egg thief; which is what it name basically translates to.

But we now know that was misidentifying the evidence.

It was a very good example that dinosaurs not only cared for their own young, but did so like modern birds (laid on eggs)

I've always loved this dinosaur from Jurassic Park. It sucks to know it was not entirely accurate for its time, because the book described it with things evidence did not support.

Here it is without the frill, but with unique lavish feathers.

about 90% of them.

those studies (I only see one there, but we'll pretend you have more) don't agree with any of the huge amount of paleontological evidence for marine anoxia during the Late Cretaceous.

So nobody takes that idea seriously.

also you should probably be aware that dinosaurs didn't exist during the Carboniferous.

How, the sail? Its sail was always a staple of the animal, which is literally what it is named for.

The only true thing that changed about it was the shape. This is no less a meme than a rounder sail.

>>2262541
It is as much of a meme as:
1. Ankylosaurus clubbed tail and heavy body armor
2. Stegosaurus back plates and tail thagomizers
3. Triceratops three face horns and bony frill
4. Carnotaurus two robust head horns, armored scooted hide, small arms without humorus bones, four fingered hands, and speed
5. Therizinosaurus claws, large dinosaurian arms, and potbelly
6. Dromaeosaur sickle foot claws
7. Tyrannosaurus big head, powerful jaws, massive teeth, small arms, and two fingered hands
8. Sauropod very long necks and sheer size (practically whales with legs)

Spinosaurus sail is simply one of, if not the biggest standout trait of the animal. This is why it was called the 'spine lizard'.

>>2263082
the recent changes to Spinosaurus have been debunked.

the "specimen" it was based on has been reassigned to 3 different species.

so the sail thing is probably bullshit. We don't actually know what its sail was shaped like yet. The old versions are a better guess than the new.

not that it matters, but the new version is known to be based on multiple individuals anyways. That dip in the sail is where they used a bone from another individual to fill in a gap. We've hit image limit so I can't show you....

>>2263129
>'possibly' other species.
Technically, even the 2005 specimen based on a upper snout could also in theory be its own species.

Even the original remains of spinosaurus could be an amalgamation of separate species, due to the lack of research and the fossils being obliterated... By this logic, it is also arguable in theory that spnosaurus itself might not even be a truly valid animal....

>>2263539
>'possibly' other species.
when the material is reassigned to 3 different species it is IN FACT other species.

that reassignment may change in the future but until it does the material represents 3 different species.

some of the material has been assigned to a different genus, so it's pretty unlikely that it will be reassigned to Spinosaurus before you die.

it doesn't matter what you could argue, all that matters is what you can demonstrate. It has been demonstrated that Ibrahim et al's Spinosaurus is a chimera.

>>2263539
>Technically, even the 2005 specimen based on a upper snout could also in theory be its own species.
since it hasn't been assigned to any species yet, you are correct.

however since it has no diagnostic traits that are different from S. aegyptiacus, it would be impossible to ever know if it's a different species unless the rest of the skeleton is found in the exact same place.

if a different species is erected that happens to match the snout exactly, we still wouldn't know which species it belongs to, since that new species would have a snout exactly like S. aegyptiacus.

that's why the authors described it as Spinosaurus cf. S. aegyptiacus. It isn't diagnostic to the species level, and it presumably never will be.

>>2252369
This dinosaur is 100% fake. One day I will be proven right. Never trust the lying chinks when it comes to paleontology. They have created an entire booming industry around fabricated fossils.

>>2263822

>>2263822
there was one fake really.. like ever (Archeoraptor) and that was still a Microraptor and a Yanornis it was genuinely an accident as both creatures were discovered in the same place putting the two fairly similar looking parts of the two fossils together and calling it complete was where the Chinese fossil hunter went wrong

Jurassic World is a good start.

If dinosaurs were alive today, and we could see the feathers, what would we call these giant scary flightless birds with teeth? "Sarus" isn't really appropriate for something that's as closely related to mammals as reptiles.

Although with most theories as such in paleontology, it is hard to say for sure specimen's death, specie's extinct, and DNA testing being impossible for ancient dinosaurs.

Okay so we all know that Sue is the largest most complete T-Rex skeleton to date, however --

What is the validity on both rex specimens C and F? C-Rex was estimated to be fuck-huge compared to Sue, while F-Rex was suppose to be even bigger. Are both these guys actually legit T-Rex specimens or some hoax? I've seen stuff on the C-Rex while F is quite alluding, not one snappy of him.
