Thanks for taking the time to check this out. The vert is ID'ed as Dromaeosaurus from Hell Creek Fm, Powder River County. I've been having a frustrating time trying to make better sense of this, since, as for as I know, there have been no Dromaeosaurus IDs in HC. Are any of you able to shed light on the likelihood of it being dromaeosaurid and anything beyond that? The measurements are 1.875" long * 1" wide * 1.625" tall. (I have a vert centrum ID'ed as Dromaeosaurus from a Judith River Fm and it's only about 0.8" * 0.4*0.5. Position may well explain the huge size difference, but I'm not sure about that either.) Any input you have would be greatly appreciated.

We were told we could find croc teeth in this Mowry shale along the eastern rim of the bighorn basin and found this fossilized vertebral bone.

Was purchased as an Elasmosaurus vertabrae from Morocco 5.91" x 6.19" I found one similar online but the one I acquired seems to be a little more on the flat side. One of the processes has been repaired and seems to be stabilized. If it is indeed from an Elasmosaur, could it just be from a different section of the spine and is why it has a flatter profile? If so, what section could it be from? I'm just trying to get all the information on it that I can. The last three pics will be of the one I found online. Thank you in advance!

I found four of these fossils in a Devonian site (Mahatango, I think). To my eye they look like vertebrae, but that seems so extremely unlikely at a site that is mostly given over to crinoids, brachiopods and trilobites. I have never found any fish there. What are they? Thanks in advance for any help. Matt

Early June, two years ago, I found this ichthyopterygian vertebra in a small nodule out of the northern French Middle Triassic, from the Upper Muschelkalk. Almost two years to the day later a friend of mine helped me complete its preparation this month. When done, one of the first things that struck me were the elongate, and slightly tilted rib attachment sites. As far as I know, such rib attachment sites do not occur in any parvipelvian ichthyosaur species, which, instead, have round, button-like, attachment sites, especially on dorsal vertebrae as my find is. Now I realise that ichthyosaur vertebrae typically hold very little diagnostic value, but I was wondering whether the peculiar rib attachments might be indicative of a super-family, family or even genus, so that I can label the vertebra more informatively than "indet. basal ichthyopterygia". Nothing is known of the species at the sites where I found this, though, based on size alone, Cymbospondylus sp. seems like a good candidate. Any other ideas? @Pemphix @sander @paulgdls @Welsh Wizard @Crazyhen Dimensions of the specimen: 41mm (diameter) x 21 (depth)

I am back from my trip/vacation/holiday/whatever-you-call-it. I went to Hilton Head Island South Carolina USA and was unsure how the shark tooth hunting was gonna go. Turned out much more successful then I thought although the largest tooth is only 12mm about half an inch. It’s a lot harder to ID these than I thought. I tried grouping them but am pretty sure I made some mistakes. I could use some help to figure these out. And I know many are too worn to ID. Couldn’t find a complete ruler so I just cut out a 1 cm by 1 inch piece of paper for scale. Let me know if more pictures are needed or if you need any other information. Here are all the finds. group 1 is missing the root but seem wider than the others. group 2, most don’t lay flat since they have a very large root. Group 3 is like group 2 only these all have serrations. Group 4 are thin with small roots although I can’t tell if the root is just very worn. The tooth in number 5 I would put with group two only it looks like it grew around a piece of something while the shark was alive and was wondering if this is true or not group 6 has a thicker blade and smaller root. 7 is angled, short, and serrated. 8 is a fish vertebra and was wondering if you can tell anything else from it. 9 are all slanted this one I’m sure I messed something up I can’t tell which ones are angled because of the species or because of mouth location. And group ten I believe are too worn to identify but this forum has lots of very knowledgeable people so I put them in, in case any can be identified. Thanks for any help. Edit: I know the teeth can turn black fairly quick but how quick is it? The teeth I found vary in amount of blackness which I assume to mean lighter ones are more recent but to turn fully black how long does it take? Thousands of years? hundreds of years? Decades? Less?

Found this almost complete vertebra on the Brazos River near Houston several months ago, missing only one of the larger processes and one of the smaller ones. I initially assumed it was just another horse or bison vertebra which are pretty common around here, but after looking at it again I realized that, although worn, one side is convex and the other is concave like in reptile vertebrae. After looking at some pictures online it bears some resemblance to alligator vertebrae. If that's what it is I would be overjoyed since the only other alligator material Ive found before is a single osteoderm about a year ago. As always, if someone could confirm my tentative ID I'd be very grateful. And an in-situ just for fun:
