Dwardius woodwardi (Herman 1977).
Slant length indicated by longest side.
Definitely the nicest D. woodwardi I own.

You need a larger homogeneous sample (from a narrow interval) of Dwardius to be able to distinguish D. woodwardi from D. sudindicus. Better chance if the strat data are solid as the former ranges from the upper (or possibly upper middle) Cenomanian to the lower Turonian. It is not known if they are simply two chrono species of a single lineage or if it is more complicated with temporal overlap. The youngest record of D. sudindicus that I have seen is from the lower part of the middle Cenomanian. All upper Cenomanian to lower Turonian Dwardius examined by me have been D. woodwardi. Shark tooth bearing deposits on the Russian Platform are often associated with less than stellar strat data.
