Ammonoid Mouthparts

[Pr0teusUnbound]

remember the story about the Baculites ammonite radula being discovered with a synchrotron? it turns out that its not the only ammonoid buccal apparatus know to science. it turns out there are at least a dozen complete specimens of ammonite beaks and radulas from the mesozoic era, plus a few ceratites from the triassic and goniatites from the carboniferous. many of them are different from the filter feeding apparatus of Baculites.

This Article just out, shows

The concretion is rich in cephalopod jaws

I would imagine there were many different kinds of ammonoids, that ate many different things.
