Yep. Lammergeiers have their own feathered beards.
I wouldn't call what they have beards. They're more of a feathered handlebar moustache.

While I wouldn't say actual beards covering the whole lower jaw is likely as it's not to my knowledge occurred in modern birds (mind you, birds have distinctly unfeathered beaks), I'd say that it IS possible.

Does anyone know where I can find a good site with a lot of up-to-date information on paleobiology? I'm an environmental science major (my college lacks a geology major and that was the next best thing) and hope to become a paleontologist one day, but I've been somewhat away from it for a few years and I'm hoping to get myself back up to speed. I'm just not sure where to start. I especially like vertebrate paleontology, but anything is helpful.

Thanks in advance.


Hmm... Lets see... Wikipedia's an obvious one, Usually blogs and stuff are the best places to start on the technical side of things. For those, I'd reccommend:
Tetrapod Zoology - Darren Naish
Skeletal Drawings - Scott Hartman
The Bite Stuff - Jaime Headden
Markwitton.com - Mark Witton
Theropoda - Andrea Cau
Theropod Database Blog - Mickey Mortimer
Archosaur Musings - Dave Hone
SVPOW - Matt Wedel + Mike Taylor
DinoGoss - Matt Martyniuk

Uh... Guys did I miss any other good ones?

Anywho, there's that, various youtube channels (I'd particularly reccommend the Thagomizers YT channel), but if I wanted to finish up with one site...

Hell Creek Forum. Most of its topics consist of just really condensed summaries of what we have for whatever paleo-issue there is, such as their super condensed list of every dinosaur specimen we have skin and/or feathers for. Things like that.

So, Leaellynasaura?

Has the paper describing that insane tail been published yet?
How complete are the fossils we have on it? Do we have the hands and feet? What shape were the claws?
How long was the head and body WITHOUT the tail?

What modern day ecosystem would be comparable to Hell Creek in temperature ranges?

Did dinosaurs have teeth or tooth-like protrusions on their tongues, like on the tongues of geese?

Possibly. I wouldn't be surprised if they did. Such structures are keratinous and don't fossilize well, and to my knowledge we have no examples in the fossil record.

if may ask, during the saurian livestream they mentioned colossal hadrosaurs not assigned to the genus Edmontosaurus. is there any articles or describing's of the fossils, or estimations of potential length?

thanks in advance

Is it likely that Ceratosaurus may have ganged up on lone Allosauruses to steal their kills. Most commonly at night under the cover of darkness. Similar to Hyenas and Lions

There is an undescribed set of fragmentary remains belonging to a Parasaurolophus-like lambeosaurine. Whether this is from Hell Creek strata or older rocks is to be determined.

It's up to the behavior of Ceratosaurus, Especially the social behavior of it, as mobbing on other specie, require some kind of social interaction which mostly lack in solitary animals.

However, given the rarity of Ceratosaurus's fossil... I can predict that they aren't really a sociel animal and have less chance to leave fossil of many individuals in the same area. Still, the information on this is really poor and is still in the shade of speculation.

Has the existence of feathers on big Theropods been approved ?

Yes on Tyrannosaurids and other Coelurosaurs. For other theropods, such as say Allosaurs or Dilophosaurs, we either don't know or that's it's very unlikely due to scale impressions found on species from that theropod group, *coughAbelisauridscough*.

depends on what you mean by big
30' seems pretty big

(largest animal with direct evidence of feathers)

although it depends on species cladistics more than size

see, with tyrannosaurs and all coeliosaurs feathers are very extremely likely definite
however with abelisaurs (example of noncoeliosaurs with scale impressions) feathers are unlikely

check out these videos, they might help:

which dinos had feathers

Convenator may have had wings based on the quill knobs, but we can't tell for sure. Certainly, the tarsal scutes at least imply that it was a possibility.

As a side note, those videos are rather inaccurate. They imply that by default large animals need to lose their feathers, when not only we know that not to be the case, but that hair/feathers actually help with cooling a large creature down:
