I took flyer on this vertebrae because it was inexpensive. The only location information I have is that it was found in Florida. It is 1.64 inches long. Anybody have any idea what it might be from?

From the album: Marine reptiles and mammals
A little collection of assorted mosasaur fossils from 2 different places that I got when I first started collecting. 2 different types of vertebrae, one is mosasaur, and the other is a questionable claim of mosasaur, a corprolite that was claimed to be that of a mosasaur, a tooth, & 7 rib fragments. 2 ribs have predation marks, as well as the large vertebra. The large vert has a round tooth indent on the very center. The 2nd rib down has tooth scratches along the surfaces, & 3rd rib down has a round tooth indent in the center, which is probably what caused a strip across the middle to break off. There are 2 other tooth marks on that rib as well, forming a diagonal line from above left of the center indent, breaking off a piece along the top, to below right. -

Vertebrae damaged during or before fossilization, from a basilosauridae. Found in Albany, GA, in the Ocala limestone formation, an Eocene deposit laid down by the swannee current between about 34-56 mya. The exact species is possibly still up in the air, since it is been suggested that it is something other than the original ID. We're still looking into the possibilities. Found in Georgia, so that limits the possibilities, but still leaves open a number of basilosauridae, including some dorudontinae such as Zygorhiza. Zygorhiza, which is what it was originally supposed to be, is iffy since it hasn't officially ever been found in GA, but I don't think that means it hasn't, doesn't that just mean it hasn't been found by scientific authorities, or confirmed by such? it seems however, that the person who ID'd it as Zygorhiza was Professor Mark Uhen, who I guess is an authority on the subject, but as before, they're not supposed to be found in GA. Another possibility from a different authority on the subject has ID'd it as Cynthiacetus, which I personally would prefer, but sadly that doesn't have any impact in the matter:(-

Zarafasaura Oceanis elasmosaurus sacral(?) vertabrae

Zarafasaura Oceanis Elasmosaurus sacral(?) vertebrae. -
I found these today in a box of fossils from my collection that I had in the 1970's. Other fossils in the box were mainly trilobites, crinoids and brachiopods. At one time, I had several thousand fossils, primarily from Ohio, Alaska and Utah. I personally collected 100% of the collection, so these fossils most likely came from oneof these states. Any help would be appreciated. Thank you.

Hi all. I’m new to the forum and I have a number of items that I’m hoping you all can help me ID. This one is from the banks of the Meramec River in st. Louis county, missouri. I’d say it’s about 7 cm wide, 7 cm long, and 5 cm tall. It looks somewhat similar to pics I’ve seen of various vertebrae, but I’m not sure. I’ve included pics of it from several angles. Any thoughts?? Thanks!

Dear fellow forum goers, These past few weeks have been quite busy, but that has not stopped me from going on the occasional fossil excursion. A few trips went by since my last posting and I decided to let some trips accumulate before posting again. On these trips I interacted with forum members @Woopaul5 and @frankh8147. The most recent trip was today, 08/12/18, and was somewhat productive. Frank found what we believe to be a part of a mosasaur brain case, which will surely be in his "finds of the year list". I was not as luck but ended up scoring a small point fragment and a jaw section of some fish. There were also some nice quality teeth that I found today. Other than this trip, I scored some nice finds on a few other trips throughout the two months. I hope you enjoy the finds, as I enjoyed finding them, and have a nice day. Kind regards, Trevor Overall Finds Stream Worn Shark's Teeth

I would appreciate any help in identifying this fossil. My father purchased it somewhere in the Western US during the 1960's or earlier, but unfortunately I do not have any provenance. It sat in a display case until my parents passed away a few years ago. Due to space limitations, these are low-res pictures, but i'm willing to take different perspectives/resolutions as needed. My apologies for the poor tags... I truly appreciate the help! Best Regards,

From the album: Holzmaden
This fossil was found by me two years ago in the visitor quarry Kromer near Holzmaden and was prepped by Roger Furze ( @Ludwigia ). Thanks again On the piece you can see a disarticulated Ichthyosaur skull with some ribs and vertebrae. You can see one eyehole very good, although the eye itself isnt preserved. Isolated bones are not that rare in Holzmaden but such pieces are very rare ! At the maximum the piece is about 24 cm long. Unprepped: Prepped: The eyehole is very good visible: (Probably my favourite part ) The other eyehole: Some more bones: A vertebra: This one could be from a juvenile which is very rare! -
This is a vertebra that I found on a gravel bar last month on the south Brazos. It is large but has a small neural opening, and I wonder if it is from near the end of the tail. Someone have a clue? It does look like a megatherium caudal that I found in a paper, but that photo is poor.

A few years back I was collecting in the Lower Member of the Glen Rose Formation. That's lower Albian in age. The sediments are shallow marine limestones and clays. Shark and other types of fish teeth are not common but do show up. I also have various bits of turtle bone. Attached are two pictures showing some of the more common teeth which I have references for and will be able to identify with no problem. With them is a small vertebra and that is what I want some help with. I look forward to your responses.

On the possible vertebrae: Was told it was a fossilized vertebrae, nothing else really remembered by me at this point. On the Amber: I’ve tried the “tests” to authenticate it, and it seems real, but because there are insects in it, I’d like to double check it’s real and not fake (I have my doubts though) (update, I’ll post the Amber picture separately)
-
Any ideas? These are the only 4 pictures. I don't know if the back was lost pre or post fossilization.

Hello I know this is dinosaur bone and I have a thought that it is a vertebrae fragment but wondering if anyone can help me identify it better. Thank you.

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.
