Yes, although Sarcosuchas most likely fed primarily on fish due to the shape of it's jaw where as Deinosuchus probably had a more varied diet making it potentially more dangerous to humans.

Also, I was going to post quetzalcoatlus next, good choice. I'll go with this instead. Something about these permian reptiles just makes me feel uneasy. Mammal like but so alien at the same time. Leogorgon was about twice the size as a male lion.

>>599739834
Cool as it is, evolution generally selects against large animals. That's why there are few living today, and extinct animals often have similar, but smaller versions, survive. It's just not efficient, as a species, to take a very long to mature. More generations of breeding in a shorter span allow more mutations to take place, increasing the chances of successful adaptation to any change in environment.

Interesting, but notable that they only noted it for marine animals. This may be because the simple volume of the ocean, as well as the increased buoyancy of water compared to air, provides more favorable conditions.
Also just because we see a lot of large animals doesn't necessarily mean that it's better to be big. Since there is an absolute lower limit on the size and complexity of organisms, but no upper limit (theoretically). The drunkards stumble and all that. Bacteria are still the most successful organisms on the planet.

i don't swim well.
so i an going to die easily i chosse /b/
also there are many parasites on the water.

good luck trying to survive beying a blob of flesh.

Helicoprion is cool. It's thought that it evolved the wirl tooth to crack ammonite shells.

I started doing the math once on how big a Pegasus's wings would have to be to get it airborne - Assuming the "horse" body was 1000 lbs.

>Basically they'd have to be the length of a school bus and flapping like a humming bird

Check out the bearded liberal in the middle trying to reason with wild animals. Will they never learn?

Inland. I'm not a fish and would be at a clear disadvantage. I'm a very strong swimmer but no gills, no weapons, can't see in water.

On land I could at least pick up a stick or rock to piss something off very slightly before it ate me.

would you rather fight ten thousand mantis shrimp sized T-Rexs or one T-Rex sized mantis shrimp?

Option B, although it doesn't really matter since I'm just going to die from some sort of pathogen I don't have immunities to pretty quickly even if I manage to avoid predators.

How the fuck did my ancestors survive this shit ?

Wasn't this tested on this stupid show where they build robot animals and measure their capabilities? I believe the fish won because way more muscles.

Othrocone would be pretty terrifying. A giant squid with a shell that swims in shallow waters? Fuck that

I have a button in my stomach so I can't swim and I have Thalassophobia. I'm going second option. Also it's a lot easier to be stealthy on land.

That's all just a theory, though.

For the most part your ancestors were small shrew like mammals that would easily be able to hide from the majority of the predators posted in this thread.

mfw piss into the face of the predator.
predator runs away because my piss is full of amonia.
i have the power of the dick, i should use it to make an social tribal culture that disregards womans as objects

>>599743892
A: if i get tired i can float but as long as im not near a reef, the open ocean is actually pretty empty and I think the sea life would be more confused about a mammal.

if i went with B i feel like everything would be bigger and faster and just see me like an owl sees a rat

Do you have a compromised immune system?
The whole point in being adaptive is so that the immune system can defend you from previously unknown threats.

I'd probably just drown, so I choose land.

that's fascinating, what a nice thread we have here

at one time humans were giants too
at one time rats were fucking monsters too

we (all species) go through these cycles of prosperity and atrophy every quarter million years or so

>>599745080
I'd rather fight the little T-Rexs

>>599745518
A scientific theory means much more than a regular theory

>>599730859
nothing but a giant rat

>>599745318
pteraspis, I think armored fish swimming around the ocean would be the shit.

Did our ancestors made those extint by trying to stand on them while they walked?
Something deep inside urges you to ride it.

Scavenged the kills or carnivores using stone knives so that our digestive organs could be selected to shrink and our brains to grow. Bing-bang-boom 2.5 million years later here we are*.

One large mantis shrimp. Ten thousand foot long trex is ten thousand feet of trex. One 30 foot mantis shrimp is 30 feet of pokey arms and no teeth.

humans never were giants,
as a wholle as a species we ranged betwen 60 cm and 3 meters.
