No dice on a pdf: the publication is nearly 200 pages long. _Gresslyosaurus_ is
reinstated by Moser based on sacral morphology: "...at the ventral side of the
left SR2 [sacral rib 2] ... there is a deep groove, which extends onto the
corpus and is bordered caudally by a strong lamella... This character is not
found in _Plateosaurus_ and _Sellosaurus_, therefore it is accepted as a
diagnostic character for a separate genus _Gresslyosaurus_ from the Rhaetian."

You're telling me that the justification of generic, to say the least not
just specific_ differentiation is a groove and lamella on a sacral vertebra? I
find this ... limited info ... hard to swallow. What is the sample size?
