Re: Oxfordian vertebrates are poorly known all over the world?

There are a few Callovian-Oxfordian vertebrates known from Europe ? England
(Oxford Clay) and possibly Guimarota in Portugal; there?s also some
Oxfordian pterosaur material from France.  In North America, there are
several marine reptiles from the Oxfordian Sundance Formation of Wyoming and
there are some Oxfordian-Kimmeridgian vertebrates from Canada.  The Daohugou
fauna in China may be, in part, Oxfordian (age is usually given as
Callovian-Oxfordian).  The Canadon Asfalto Formation of Argentina, which
produces vertebrates, is also considered Callovian-Oxfordian.  Part of the
Tendaguru Formation in Tanzania may be Oxfordian, though I don?t recall
offhand if that pertains to any of the vertebrate beds.
