And what about goniopholidids?, huge crocodylomorphs, with short limbs and generalist cranial and teeth morphology as modern crocs (mainly acuatics), but however... with very rigid paravertebral armor as in some atoposaurids (mainly terrestials). I can imagine what is the reason for all this, but I'd like to know especially the ecological interpretations as you have done with the episode of Theriosuchus.Eduhttps://www.blogger.com/profile/00053755713716525644noreply@blogger.comtag:blogger.com,1999:blog-3653345901774701895.post-46076979376523083252014-02-22T16:00:11.827-08:002014-02-22T16:00:11.827-08:00Off Topic: I found this on YouTube by random chanc...Off Topic: I found this on YouTube by random chance (Not Mine.), and wanted to know what you thought about it; Istiodactylus Walkcycle: <br />http://www.youtube.com/watch?v=WTwdMiZ0HUI<br />(See also V.1: <br />http://www.youtube.com/watch?v=2_pelk2duKo<br />Test (With multiple angles of view, and a faster speed.): <br />http://www.youtube.com/watch?v=NNHlYkrSIA8<br />)<br /><br />--SeanAnonymousnoreply@blogger.comtag:blogger.com,1999:blog-3653345901774701895.post-29458676504933142542014-02-15T06:00:44.292-08:002014-02-15T06:00:44.292-08:00Would be nice to see someone do one however.

As noted above, I...Thanks for the comment, Sean. As noted above, I'm not aware of any endocast or CT work, but this may be my own patchy knowledge of ancient croc literature. I can verify the nature of the lower dentition, however: like many Crocodyliformes, atoposaurids have large 'pseudocanines' which slotted into a notch on the upper jaw. You're no doubt aware that there's almost continual discussion about how much 'lip' to give reconstructions but, based on modern crocodilians, I thought it appropriate to have the large tooth on display here.

Two more to go!<br /><br />2) I hadn't seen that, thanks - will reply to it at P.Net.<br /><br />3) Fruitachampsa belongs to a group which (probably) split off from Crocodyliformes fairly early in their evolution, whereas atoposaurs are nested more deeply within the clade. So yeah, some of the features shared between these animals should be considered convergent.Mark Wittonhttps://www.blogger.com/profile/02524696111911168322noreply@blogger.comtag:blogger.com,1999:blog-3653345901774701895.post-81772454378083482402014-02-14T02:48:53.396-08:002014-02-14T02:48:53.396-08:00Not to my knowledge, Duane but, as will become app...Not to my knowledge, Duane but, as will become apparent as I field comments here, I'm far from a croc expert.

Any ct scans on the brains of these cursorial crocs or similar types? It would be interesting to see how what is going on with balance, inner ear or how they might differ from aquatic species.Duane Nashhttps://www.blogger.com/profile/14467779935085970909noreply@blogger.com
