Ok amphignathadon guentheri is the only frog with "true" teeth in their bottom jaw.So what is the difference between the teeth of a horned frog?Are horned frogs teeth cartlidge or something and same with the pixie.

thanks

My understanding is that the odontoid structures (pixies and horned frogs) are actualy an extention of the lower jaw bone.

Agreed. They are projections coming off of the lower jaw itself.

I don't have a pic of the lower jaw, but this is a pic of the upper jaw of a Cranwell's horned frog (this particular specimen was an albino male.) I had him for a few years and he died during the winter of '2002. So I placed him outside, unable to bury him due to frozen ground. That summer, apparently nature had done its magic, because I found his skull perfectly cleaned in my garden. So I bleached it and added it to my collection (am I the only animal skull collector out there?
Upon examining it, no, there are no "teeth" like we have, that could come out. But the edges of the jaw are serrated, sawlike, and still very sharp.

You're not the only one collecting herp parts! The crowns are loosely bound to the base and probably lost during decomposition, which may be why you don't see any on your skull.

FYI: Ranids typically lack teeth on the bottom jaw, Bufonids lack teeth entirely, and it seems that MANY amphibians have teeth on the roof of their mouth!

I never thought of that. Seems so obvious though.
So you're a bone collector too? What kinda skulls do ya have?

you should go looking for snakes near Houston sometime. We found 3 decaying dogs in about 2 or 3 hours while looking for snakes on Saturday, and that is not uncommon. People kill them in dog fights a lot of time, and then just bag em up and toss em in the woods. Really sad...and they smell really nasty lol. Andy

Not much now. I do like my opossum skull with so many teeth. I will be working on articulating a bullfrog skeleton soon.

Upon a second reading, that title sounds really bad . I collect all kinds of skulls and various bones while hiking. I use them in lectures in class. Totally illegal to collect them, but it is hard to resist when you find them.

Colchicine, I have always wanted to articulate a a skeleton! Can you tell me how you are doing it? Or direct me to a resource to read on the subject? I don't have a full specimen yet, but I am always on the lookout (my husband is convinced I would bleach his bones if he died ). A bullfrog would be awesome. Where did you get yours?
