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(?) vertebrae. -
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!

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! -

I fossil hunted the lower limestone flag member of middle Eagle Ford Formation in Travis County, Texas USA yesterday. I came up with three nice finds. The first is a 130 mm x 75 mm section of a large ~2' diameter ammonite. Two pics included but it is difficult to make out. I think it is an EUOMPHALOCERAS genus, based on GEOLOGICAL SURVEY PROFESSIONAL PAPER 274-C 1955. Any different opinions? The second find is a 15 mm wide Ptychodus Occidentalis per Shawn Hamm's recent email help for me on a couple of 10 mm wide Ptychodus out of 8 total located ~1/2 mile NE from the subject area. Check out last two ptychodus pics in question. He says ridge bifurcation doesn't always occur on P. Occidentalis. Sometimes the ridges extend to the marginal area and curve anteriorly without bifurcation on one or both sides. The third is a shark vertebrate?? The largest I have seen in Travis County at 33 mm diameter. All three were present in the same 20' x 20' area in a 2" thick layer of limey mud rock coated top & bottom with thinner layers of oyster shell hash. Wow! Lots of fun!
