Hellbender Posted March 31, 2005 Share Posted March 31, 2005 Are mosasaurs more closely related to snakes or monitor lizards? Various morphological characteristics such as features in the skull point to at least in-between, or closer to snakes. Having seen a fossil of Tylosaurus myself, while it looked indoubtedly snakelike, I also recognized that it had common featues with modern monitors. Anyone is welcome to discuss their various homologies with snakes and monitors or where they fit in that particular family tree. Link to comment Share on other sites More sharing options...
Mokele Posted April 1, 2005 Share Posted April 1, 2005 Unfortunately, AFIAK, right now this is one of those Contentious Issues which have no clear answer. On one hand, there *are* a lot of similarities. On the other, it's possible that many of them are convergent and some recent work I've heard indicates they aren't *quite* as similar as they seem. I'll try to dig up that work, if I can (I left the book in my office). Mokele Link to comment Share on other sites More sharing options...

I have read lots of conjecture about mosasaurs being intermediates to some degree, but any new, up to date info in more then welcome. Link to comment Share on other sites More sharing options...
