Coastal floodplains and forests for the next two.

Meanwhile temperate rainforest seems best for Pachyrhinosaurus and Yutyrannus, with arid plains or open scrubland for Alamosaurus and Quetzalcoatlus.

remembering the alamosaurus,
before I joined this site, in the saurian topic, I saw you guys debating about hell creek alamosaurus, how possible is this?

I believe I've said my piece on Hell Creek alamosaurus there.

hi

I'm also curious if they're going to look into the indeterminate Parasaurolophus remains found in Hell Creek.

@Paleosaurus I believe they had mammal-like cheeks though I'm definitely not an expert on that subject.

@Rhodedicut It is definitely quite possible that Saurian could look into it, though we know so little about it. I guess we'll just have to wait and see!

Now for some more questions of my own:

1. Since Gastornis has been shown to be a herbivore (though some of us have pointed it out that it could've eaten a small animal from time-to-time) I've been looking into the apex predators of the Paleocene and Eocene such as Titanoboa, Borealosuchus, etc.

However, I did discover that some of the earliest members of the Terror Birds were found in the Paleocene and Eocene such as Paleopsilopterus (about 61-59 million years ago in Brazil) and Eleutherornis (about 48-41 million years ago in France and Switzerland).

Since Paleopsilopterus and Eleutherornis were about 1 meter and 1.5 meters tall respectively, could they have been the apex predators in there respective environments? I'm not sure if Paleopsilopterus lived in the same environment as Titanoboa or if there were larger predators in Eleutherornis' environment.

2. Many large animals such as Woolly Mammoths and Bison from Siberia also moved into North America via Beringia during the Ice Age. However, we have yet to find any evidence of Woolly Rhinos or Elasmotherium in North America.

Do we have any good guesses as to why Elasmotherium and the Woolly Rhino did not also live in Beringia and North America? Was there anything about those environments that did not appeal to them as much as other megafauna?

3. I have been doing research on the Bone Wars and was wondering if anyone happens to know of a complete list of the VALID prehistoric animals found by Marsh AND the ones found by Cope? I have found hints of a few prehistoric animals found by them but a complete list would be appreciated!

Thanks again everyone!

Regarding the rhino, my guess would be that they were more sedentary and territorial than other species, thus less inclined to wander far enough to reach a new continent.

did woolly rhinos and elasmotherium live together

I believe they both lived in Pleistocene Eurasia at approximately the same time, but given how territorial most modern rhino species tend to be I doubt they would have associated with each other.

can someone give me a list of all the dinosaur that live in polar regions when they were alive (not animals that were discovered in polar regions but was tropical at the time)

Can you elaborate on that? Do you mean prehistoric creatures from cold climates?

yes that is what I mean anything before the ice age because we all know what lived there

Not really an issue of territory, more like different ecological niche.
IIRC black and white rhinos are the only ones that coexist (perhaps javan and indian used too, I don't remember), and they live in different habitats (bush for the black, savannah for the white) and have different diets (browser the first, grzer the second).
I remember seeing a scene in a documentary where both species happened to show up at the same watering hole, and there was no aggression (despite being two mothers with calves).

Hatzeg island predator sizes?

Balaur and Hatzegopteryx.

The first is small (think dromaeosaurus sized), and the other is a flying, murderous giraffe-stork. That's actually the size of a giraffe.
