It's not a matter of size, more of muscles and body proportions. Size only affects the distance covered, as a larger animal can move for longer distances.
size can also mean bulk which can add strength bradycneme were likely more bulky than other Alvarezsaurs and were likely good at swimming. Most alvarezsaurs likely were not to bulky

also what was found first B. draculae or H. andrewsi

To my knowledge the only animal that might not be a swimmer is a giraffe, and we still aren't even sure on that. Alverasaurs in proportions are very similar to Modern palaeognaths, and they can swim fine.

Are there any photos of this specimen?
Its a Chasmosaurus belli skin, i just wanted to see if there were photos to confirm what look like giant spike/quills

Also Dinosaw, looks like both were described in the same year.

Unfortunately, I can't find other pics of that specimen. I *THINK* I found a replica though:

But here's what I can tell you:
Sternberg. 1925. "Integument of Chasmosaurus belli" Canadian Field-Naturalist. You'll find the description there. If you actually find the paper.

Some of the comments adressed pretty well why the guy who made the video is plainly wrong, I think further comments ain't necessary.

the only thing I agree with is the hair but other than that it is unrealistic

Does anyone know anything about individual species of Titanopterans? I'm looking for size and the rock formation they came from specifically.

There is always something going on...

What would have Koskinodon and Apachesaurus ate? And how would it have hunted?

Well, as it so happens, there's a lot. Too much for me to post up individually, but hopefully, this link will take you to an entire database worth of stuff:
http://fossilworks.org/?a=taxonInfo&taxon_no=224437

As for Apachesaurus and Koskinonodon, they were metoposaurids, with wide, flat heads, raised eyes etc. So they may have been ambush predators which sat on pondbeds or something and snapping up prey that swam past, even possibly sucking them in as they opened their jaws.

Thanks, DG!

Also, what kind of environment did the Cloverly formation have? The LITC post on Aquilops said it was seasonally dry, and Wikipedia ways it was a swamp or floodplain... So what would this be? Tropical Dry Forest? Temperate Rainforest?

I did some research on the foliage a while back, and apparently it was mainly redwood, with addictional ginkgoes and ferns.
Not really sure what biome would that classify under.

I did some EXTENSIVE research on this a couple months back. On the basis that similar, if not the same species can be found right across from Oklahoma, Wyoming and as far north as Montana, I've come to the conclusion that the whole ecosystem was quite expansive.

Basically, you'd be looking at a lowland, subtropical dry forest environment with expansive groves of cypress-pine like trees (Cheirolepidiaceae) which dominate the landscape, with a few other kinds of plants thrown in the mix. Trees that were drought and sun-tolerant. But their groves were often monospecific, if not low-diversity.

Other xerophilic plants were common. Particularly bennettites and true cycads of all shapes and sizes. But that's not to say droughts were common enough to call the place arid. There was enough water and soil moisture to supply water clovers, quillworts and liverworts, among other semi-aquatic plants and mosses. Ferns too. Hell, ferns especially were really diverse, with tree ferns (most similar to what we see now, but at least one genus was genuinely BIZARRE looking), the typical ground ferns, and some superficially grass-looking ferns, umbrella ferns (and if I'm right about one particular species a GIANT. MANGROVE. UMBRELLA FERN).

There was also at least one ginkgo, one araucaria-like tree, one kauri-like tree species present. And a sister species to our modern day Tasmanian Pencil Pine (Athrotaxis) somewhere in there as well.

Overall, the big trees were sun and drought tolerant, but they kinda were able to create a humid enough environment under them for other things.

So if yer lookin for a specific term for it, the closest modern Earth has to that would probably be a temperate or subtropical dry forest.

I once saw a picture and read about a dinosaur foot that still had some dry skin and meat around it. Does anybody know if it is real and which dino it was from?
Was it by any chance this?

If it is that's an Upland Moa foot.
Yes! Sorry for the late respose, I hadn`t checked this section. Thanks for letting me know which animal it was from! :) I thought it was a dino, though.
