Flying Animals : Pteranodon longiceps and Quetzalcoatlus northropi.

The American bison is barely seen in the image but that is the largest land animal alive today in North America. Again and again,it's the same story. In any megafauna image, the one thing people note is that the extinct animals are much larger than the modern animals. Next time when you see a large land animal like the bison or elephant or rhinoceros or giraffe or hippopotamus, you should feel happy because after all these are the largest land animals alive today.

The largest species of animals from North America as seen in the image :

Largest bovid - Bison latifrons

Largest canid - Epicyon haydeni

Largest camelid - Megacamelus merriami

Largest living cervid - Alaskan moose

Largest equid - Equus giganteus (Possibly the largest horse that ever existed.)

Largest ankylosaurian - Ankylosaurus magniventris

Largest ceratopsian - Eotriceratops xerinsularis

Largest stegosaurian - Stegosaurus ungulatus

It can be a debate whether Tyrannosaurus rex is the most heaviest theropod. Nonetheless, it had the most powerful bite of any terrestrial animal as well as it possessed the largest known teeth of any terrestrial animal.

Some of the largest dinosaurs are known from North America. Well-known sauropods include Brachiosaurus, Diplodocus, Apatosaurus and Brontosaurus. The most massive known dinosaur is Alamosaurus sanjuanensis which either rivals or slightly bigger than the South american Argentinosaurus huinculensis.

You know what else I think you should try? A picture of a lineup of the largest arthropods (both living and extinct). Can you do that? I would be impressed to see how you would use your Photoshop techniques for that.

I truly love the way you make your megafauna pictures, lining up all the animals together by continent/subcontinent/island. They're all very good. But I think you should trymaking Ocean/Marine megafauna pictures, starting with the Pacific Ocean. Try lining up the largest marine animals in those underwater pictures if you can, like the blue whale and the prehistoric Liopleurodon for example (not excluding fish and invertebrates).

Amphicoelias altus is way too big. While the A. fragillimus business is too sketchy to not consider a nomen dubium, the A. altus holotype seems legit. But it isn't anywhere near A. fragillimus' purported size. It was roughly the same size as Diplodocus carnegii or Barosaurus lentus: bigger than anything walking around today, but no sauropod giant like Apatosaurus ajax or Brachiosaurus (let alone Sauroposeidon or Alamosaurus).

Furthermore, Iguanodon is (was) endemic to Europe. All 'Iguanodon' found elsewhere have been discounted. I suppose it doesn't help that, other than size, Iggy was as plain a transitional ornithopod as can be. Almost any midsize ornithopod could be mistaken for a new species, and a lot have been. But I don't think anyone even thought they'd found I. bernissartensis outside of Europe. There may be a large stem-hadrosaur like Iguanodon you're thinking of, but if it's North American, it probably ain't Iggy and certainly not the coal critter.

There may be other issues, but none that pop out. Quibbles aside, helluva line-up. Shows what this continent is capable of given enough time. Well done, sir.

Some sites have wrong info about animals size and other things. If you search as Iguanodon North America, you will see some results which will say Iguanodon also lived in North America.There is one named American species but still it seems to be in confusion. Eventhough the species i mentioned has the last name which is from Europe,i didn't properly noted that. I have removed Iguanodon from here and moved to the image where it belongs. Thanks.

The "Iguanodon" fossils belong to Iguanacolossus or Hippodraco.

If anyone wants to make American great again, just bring these animals back to life. lol

ScottHartman's neck posture for brachiosaurus? Nice work
SameerPrehistorica Featured By Owner Feb 3, 2017  Hobbyist Digital Artist
Yes.Just thought about giving a different neck posture.I would prefer the neck posture like seen in Sauroposeidon in this image,more upright. In all the other images, i have that old Brachiosaurus in a more upright pose. How we can know whether these sauropods normally held their neck more upright or somewhat lower while they walked.

To be fair, African elephants are similar in size to the recently extinct mammoths and mastodons.

And the larger ones aren't recently extinct.

Have you ever considered numbering the animals? It's very hard to match a name to an animal.
