Hell Creek Amphibian sketch dump by Tomozaurus Hell Creek Amphibian sketch dump by Tomozaurus
Crappy sketches!

Just working out the appearance of the various Hell Creek amphibians. There are a surprising amount of salamanders compared to frogs. I assume that this might be surprising to me as I live in a place with no salamanders but plenty of frogs. Are there places in the present day where salamanders still hold the numbers?

I should have reduced the limbs of the Scapherpetontids more than I did, but oh well, they're just super quick sketches to work out the basic form.

Did habrosaurus really have no back legs?
Also, citations?

I don't think any limb elements are known, but sirens don't have hind legs, so it's parsimonious to assume it didn't either.

I used lots of individual papers originally, but later found that most of them can be found in Bryant (1989) "Non-Dinosaurian Lower Vertebrates from Montana and Wyoming".

Thanks for the citation, and correcting me about Habrosaurus. I had it associated with a hellbender in my mind, and completely skimmed over the fact it's a siren.

No worries man. More to come for lepidosaurs, mammals, etc.

Mesozoic amphibians are rare in palaeontography, no?

Yeah, I suppose they are.
