I feel like redrawing this one, since The original drawing is over a year old now

Hello guys! So well know about prehistoric animals right, and some people might know about seed worlds a kind of Speculative Evolution that has an animal be seeded onto another planet, kinda like Kaimere. So I'd like to see everyone's prehistoric animals seed worlds, because I'd like to make a seed world where some of these creatures are seeded, and it'll sorta like Serina but in a seed world of a seed world. Btw only seed world with prehistoric animals only because this fandom is about prehistoric animals.

Prehistoric planet was a groundbreaking series about paleontology it got a lot right, but the writers are human and they definitely got lots of things wrong This series will address these problems formation by formation, creature by creature, some animals will be ignored because they don’t have any glaring issues that i can see, for example, trike seems fine so it won’t show up here.

T. Rex

Prehistoric planet’s t-rex has a few problems, first of all it’s head is too short and round, and it’s lower jaw is slightly too long and the back of the jaw is a bit large, judging by musculature it should look like this

Also the nostrils seem too mammalian and flared out which no reptile had, this seems to be a large problem but it only seems present in the sauropods and hank here.

Overall 6.5/10

Pectinodon

Pectinodon was a confusing ride of research I thought it was a tooth taxon but later I learned the holotype UCM 38445 was just a tooth but the paratypes had the same teeth but with a front dentary and lower braincase, but it is still nonetheless it is fragmentary so based on stenonychosaurus the jugal and quadratojugal seem a bit downturned and its tail is a tad too flexible. I’m not sure, I’m just going off my previous knowledge and wikipedia.

Overall 7/10

Pachycephalosaurus

Ok, this one is the most nitpicky one I will do so far, pachy here has legs that are either too long or too thin, the head seems pretty good, it has a proto beak on both jaws. But the biggest problem is the face osteoderms being in the wrong position, I can’t explain it any other way. The head spikes seem too long, but that could just be keratin sheaths.

Overall 8/10

But remember, I am only listing the inaccuracies to stop the arguments and because I can’t list every single accuracy, judging by how much it got right, it is without a doubt one of the best paleo documentaries thus far.

If you have anything to add please put it in the comments. And please don’t argue, be civil, don’t insult each other, keep it on topic, and just be normal.

I'm talking about this thing in case anyone is dum

Spinosaurus isn't even a Solar System in the face so that they are bad Anyway there's also not taking a look around and is actually a robot looking wall break out the window and sees Jesus christ on his head from his mouth he can regenerate from that point in permabanning him with a swing of his might as fuck ngl This is also completely unphased by anything near an actual challenge instead of fuck Obama took that personally Allen seem pretty much everyone is cunfused and HOLY SHIT HE shouts at Irritator who decided to epicly troll do anything to protect the page about him and turn them into horrific abominations that he doesn't really get creative with these so that they are bad gay

That went places. It was kinda annoying to me cause my phone kept suggesting Polish words, so I had to manipulate it a little and I wanted to małe at least a tiny bit coherent. Let's do one more lmao.

Pectinodon was vakishim from the hit film Transformers devastation soundtrack on his belly and it commits Doom Slayer just because some birds have bizzare traits doesn't really do that and she sits next trick of his versions are giant metallic balls and is actually worthwhile to among these lines big sad but he like moves out of the elevator in the face so hard black hole and is actually a robot looking mf from uranus explodes Saint Laura who slides under the Capybara noises men are the ones featured white burning state he was from Ultraman Powered though and gets revenge on Red laser swords clashing in the chest and he doesn't get to show up by McDonalds customer

That went even more places

K I'm done, now you do some

It was an ordinary day in late Cretaceous North America, dinosaurs doing their normal things, mammals coming out at night to do their things, in general, it was peaceful. The Pectinodon emerged from it's small burrow during a crisp morning in the month of spring, the snow of the winter had melted, and now it was warm. It spotted something peculiar, however, in the sky was what seemed to be a second sun, passing overhead at extreme speeds, headed south. It paid no attention to the odd thing however, and attacked a small mammal, making the creature it's next meal, then it heard a bellow, and immediately had one instinct: RUN, the Pectinodon ran away at it's highest speed, hearing the footsteps of the heaviest theropod to ever live. And although it escaped the beast, something far worse was headed for it's home. It spots multiple glowing streaks suddenly paint the sky, coming from the direction of the south, where it seemed like there was a second sunrise. It felt the air get hotter and hotter, then felt it's skin getting drier underneath it's coat of feathers, it looked for somewhere to hide, then, BOOM. A hunk of flaming rock crashed nearby in the underbrush, setting multiple trees ablaze and flinging the Troodontid, it quickly got back on it's feet and continued running. Spotting a Tyrannosaurus on fire, shrieking in pain, a herd of triceratops also began fleeing away from the direction of the flaming debris, then something else happened, the ground shook intensely, as if a herd of a thousand Alamosaurus were walking directly beneath them. Trees began to become uprooted and collapsed due to the quake, and the Pectinodon found a small hole in the ground, entering it quickly.

After a few hours, it surfaced to see what had become of it's home.. it was unrecognizable, the sky was darkenned and gray, there was almost no trees left standing, and the ones still standing were on fire, a chard tyrannosaurus skeleton was left outside the burrow it had hid in, and there was something truly terrifying: there was almost nothing left. A few dinosaurs still scurried about, such as a single Tyrannosaurus, though it was in horrible condition, it's skin burnt and appearing insanely starved. There was no herbivore in sight, just a few carnivores searching for something to eat. The Pectinodon itself could not find any food, a few birds flew overhead, although even they were in small numbers. And the Pectinodon knew, this was likely the end. It lived off a few small mammals, but it was not enough, eventually the Pectinodon began getting hungrier and hungrier, then finally. 1 month after the cataclysm that shook and scorched the planet, it starved to death.

Just like Troodon, Pectinodon is only know from one tooth. Why isn't Pectinodon considered undiagnostic if Troodon is undiagnostic?
