Notidanodon Posted February 19, 2021 Share Posted February 19, 2021 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 1 Link to comment Share on other sites More sharing options...

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?
