Re: Leptocleidus question

Our site in South Dakota has numerous juvenile remains
of Trinacromerum. We have some femora (or humeri)that
are only 8 cm in length and a few that are three times
that. We think this was a shallow area off an island
and it also may have been used as a breeding area.
If you do get a copy of this article I would love to
see one myself.
Thanks for the information!
