Hi guys, I thought I’d start a thread for what is in my opinion, one of the most under appreciated group of marine vertebrate fossils. Anyway, to provide some info on these ratfish and why I find them so interesting, primarily I  am drawn in by their rarity. Unlike sharks, that shed their teeth on a regular basis, these fish have one set for life! Anyway, enough talk, more fossils, I will start with some very uncommon jurassic ones, if anyone has any, please add to the thread:rolleyes:

From the Carboniferous of Bear Gulch, Montana:
Echinochimaera snyderi Lund, 1977

Echinochimaera snyderi Lund, 1988

 

Echinochimaera meltoni Lund, 1977

 

Echinochimaera meltoni Lund, 1977 - a Carboniferous ghost shark or ratfish
 

Not a chimaera, but an undescribed  Cochliodontiformes from Bear Gulch. Cochliodontiformes are close relatives of the chimaera.

Yes, they are great creatures. Just a pity that I will never see a living chimaera. The natural habitat is at 200m and deeper.  A bit too deep for diving -   why can't they just live in shallower water?

Exactly... They're so stubborn, don't they know that we're the superior animals!?

Superior animals?:zzzzscratchchin:  Well, sometimes I doubt that - but that's another story.
