A reconsideration of the origins of the ‘typical’ Cretaceous inoceramid calcitic hinge plate in the light of new ultrastructural observations from some Jurassic ‘inoceramids’

:  Marked differences occur between the hinge plates of Jurassic and Upper Cretaceous British ‘inoceramid’ species. Albian and Upper Cretaceous inoceramids had the poiriform calcite hinge plate with closely spaced resiliifers that is widely associated with this extinct bivalve family. The whole stru...
