Question about lithostrotian sauropods



Dear list members,
Is there any confident record of pre-Campanian lithostrotians with
such characters as biconvex first caudal vertebra or strongly
procoelous middle and posterior caudal vertebrae? In another words:
which is the older ocurrence of such a sauropod?
I would greatly appreciate if anyone can shed some light on this.
Regards,

Matías
