POSSIBLE PLIOSAUR OR SIMILAR PREHISTORIC REPTILE FOSSIL VERTEBRAE UNIDENTIFIED

Description

POSSIBLE PLIOSAUR OR SIMILAR PREHISTORIC REPTILE FOSSIL VERTEBRAE -- UNIDENTIFIED & AS-IS -- collected by an amateur hobbyist in Florida -- offered for an extremely low price -- PLEASE REVIEW PROVIDED IMAGES CLOSELY -- WHAT YOU SEE IS WHAT YOU GET (WYSIWYG) -- no refunds/returns.
IMPORTANT:
Please note that even as an amateur I understand the exposed sediments of Florida to not be old enough or known to contain any such creature. That said however, the fact remains that I have physically collected what I believe to be fossils from a prehistoric reptile.
In my opinion, some of my best specimens appear to clearly contain/represent reptilian features -- marked up pictures of a few of these are provided with commentary for added context only to demonstrate why I theorize what I do. Please note the fossils shown in the marked up images are not being offered for sale AND ARE NOT INCLUDED WITH THIS AUCTION.
Thank you & happy bidding!
