"The Luoping site dates from the Middle Triassic
and contains one of the most diverse marine fossil records in the world," said Professor Mike Benton.
A durophagous dentition has been described for several clades of Middle Triassic
marine reptiles: placodonts (but see Diedrich, 2010 for an alternative interpretation), some ichthyosaurs (Omphalosaurus, Tholodus, etc.; McGowan and Motani, 2003), claraziids and thalathosaurs.

For example, the Buntsandstein in Germany corresponds to the Lower Triassic while in Luxembourg and a large part of Spain it corresponds not only to the Lower but also to the Middle Triassic
(Virgili et al., 1977, 1987).

Gondolelloid lineage that originated in the Sephardic realm, westernmost shallow Neotethys, from where, in the course of the Ladinian and earliest Carnian, some of its species spread to the world oceans, before extinction as a result of the Carnian salinity crisis.
