<<Pycnodontiformes, a group that fed on hard stuff like maybe corals,
molluscs and/or echinoderms, got caught, too, according to Vertebrate
Palaeontology, but Guimarota -- A Jurassic Ecosystem says they lasted much
longer; their round, hard teeth are certainly very good to rework, but
that's all I know.>> 

I supposed that this is common paleontological culture. Complete and
perfectly preserved pycnodonts are preserved in the Lagerstaetten of Bolca
(Verona, NE Italy) which is Eocene (50 my) in age. They have been studied
and published.
