Hello everyone, I saw this on a Calvert Cliff Facebook group from John Nance of the Calvert Marine Museum, and I figure it should be here too. “Calling all Brownies Beach collectors! If you found any pieces of leatherback turtle shell in the past year they likely belong to this guys shell! This shell was spotted and collected last May. It was first reported by a Brownies Beach collector and others have since added to it. (Will add names with permission.) It’s coming together beautifully! A new donation of 76 pieces will surely help to fill some gaps. If you’re willing to donate what you’ve found we could keep building this amazing animal. Of course you’d be given full credit for your contribution to the project.” I encourage any of you who have found shell pieces at brownies to take a look just and case and drop by the CMM. They are a great institution, very much worthy of the donation.

Ok, so this is supposed to be a spinosaurus vert, one with part of the sail. At first glance it seems perfect, but upon further study, while trying to place it on spinosaurus skeletons, it doesn't seem to match any exactly. For one thing, spinosaurus sails, at least in the relatively insignificant amount of individuals on display, sail bones that don't go any higher than this one(it appears this is a fully intact sail vert), don't seem to get as wide. And the ones that do, then continue up and get thinner. There ARE similar shaped "sail" bones, at the transition to the neck, and tail, but those aren't as tall as this one. The main bone itself appears to be from the tail, or rear part of the sail, but....well, anywhere that one part of the bone fits well, doesnt seem to match the rest of it very well. Sadly I can't find any good images of many of each type of vert, and anywhere that has good close up views of verts, only have 1 or 2 of any type, which isn't good enough to come to any sufficient conclusions. spinosaur fossils(specifically verts), seem to be something they work with a lot, so I would be very surprised if along with all the other spinosaurus verts they get in, they would end up with the sail spine of some other animal. And if somehow so, then not realizing it.
