Hi again. Last weekend I took a trip to Old Hunstanton to check out the amazing contrast of formation cliffs and with hopes of finding some nice fossils. The cliffs are made up of three layers the lowest rusty brown colour is the Carstone Formation of the Early Cretaceous Albion Stage. The band through the middle is a bright red colour known as the Hunstanton Formation also Early Cretaceous Albion Stage. The top layer is the white Ferriby Chalk Formation from the Late Cretaceous Cenomanian Stage. What a contrast! These cliffs feel much safer to walk below unlike Charmouth or Lyme Regis. The material is very solid and the white layer doesn't erode quickly. It wasn't the place for looking for fossils that the sea had washed out. It is also a very shelly beach, so my eye was struggling to pick out fossil shapes with all the broken shells everywhere. I did find some interesting looking things in the large chunks. This rock was a good meter across, so I couldn't collect it. It contains a lot of shells, belemnites and possibly sponges, but please correct me, as I don't really know a thing. Then this nice piece with lots of small pieces. Sorry I forgot to take a ruler with me. I did find some carriable promising rocks. I've brought this lot home with me for some practice prepping. Does anyone have any idea of what I might find in any of these rocks? Where would be a good place to start? I'm using a dremel 290. Thanks, Jes.

Hi everyone, Please help identify a few fossils, likely marine life - all found in Central part of Saudi Arabia (location has abundant fossilized coral). thank you! Ps. Ruler is in cm #1

Hi guys, I made this post about this small theropod tooth from the lance creek formation, Wyoming, USA. I bought it years ago and it was sold to me as belonging to a dromaeosaurid. It doesn't seem to me that it corresponds to any "raptor", but to a baby of Tyrannosaurus rex/Nanotyrannus lacensis. What do you say? Thanks in advance! Ps: the tooth is 1,2 cm/0.47 inch long and 0,6 cm/0.24 inch wide.

Hi guys, these days i was given this claw coming from kem kem as a birthday gift. This fossil was sold as a theropod claw, but it looks anything but to me. I assumed it could belong either to a sauropod cub or to a strange lizard not yet described. What do you think? THANKS XD

Hello! I found this amazing fossil on my mom’s property in Pueblo, Colorado. I’ve tried to do some extensive research online to see what type of vertebrae animal/marine life this is. Could you please help identify? thank you so much!

Hello everyone, I'd like to submit this vertebra to you to understand if it really belongs to packycephalosaurus and possibly if in your opinion how much it has been reworked. Indications on the label: Dimensions: 125mm Origin: Hell Creek Formation, South Dakota, USA CRETACEOUS-Upper Cretaceous, Maastrichtian (66.0-72.1 million years) Thank you very much

After no rain for many months we got a big 13 foot rise last weekend. I was hoping that would wash away all the mud and uncover many great fossils. Unfortunately it was still few and far between. The mud has been halfway washed away, which is halfway to where we want it, but the fossils are still not uncovered. Here are a few of the things i found: A couple decent but small mosasaur verts. Also the in situ shots. Decent fish jaw. Not sure which species though. A cool shell from the grey shale zone. All I ever see are impressions but this came out whole with nacre. 1. Coprolite? People find it all the time but I just don't have an eye for it. However this looks like a dog just had a fresh one on the ground. 2. No idea. Looks like a modern bone but hard as a rock. Maybe it is just rock? 3. Last looks like a fossilized jaw bone but is modern unfossilized non-jaw bone. It is amazing how much it looks like the fish and mosasaur jaw i found earlier. Anyone know what part of the animal this is from?

Found this fossil in a riverbed in Fannin County (North Texas) while hunting for fossils from the cretaceous period. (This is a follow-up from the same trip as my previous post - thank you to those of you who helped ID the mosasaur vertebra! And also thank you for correcting my terminology on mosasaur vs mosasaurus ). I'm not totally sure what this is (at first I thought it was nothing too special - possibly just a very eroded Baculite as we were finding many of those in the area), but on closer inspection, there are fine striations on the fossil that make me think it is bone. My current guess (based on those striations and the longish/slightly curved shape of the fossil) is that it is a fragment of rib, and further, (based on the facts that everything else we were finding was from the cretaceous and that mosasaur are the only large marine vertebrate that I know of being regularly found in the area), that it is a fragment of mosasaur rib. However, I am not sure about this and am hoping for some more help on identifying what I've got here. I hope these photos are good enough to see the details (i've tried to shoot them in half-decent light). If you zoom in, you can see the striations I'm talking about fairly well. (See dime for scale). Here are both sides of the fossil Here are the ends And here is a closer shot of the more intact side So in summary, I'm wondering if I'm right (or even on the right track) that this is a fragment of mosasaur rib? And following that up, whether ribs are identifiable by speciesm (probably not, but worth a shot )? Final sub-question that is probably totally speculative, but I'm curious about: there are a lot of indentations and gouges in the fossil. Is it possible that these are marks from a predator and/or scavenger (e.g. sharks) chewing on the dead creature's carcass? Or is it more likely to just be erosion? Thanks for putting up with so many questions!

Found in the Maryland Cretaceous Potomac Group, Other prints and bones have come from this spot. Just wanted to get an ID on a potential print.

I went to the North Sulphur River twice in October with little luck. The first time was after a rain that I thought would get a big rise but only got about a 1 foot rise. The second time saw about a 5 foot rise but each time the rain did nothing to wash away all the mud. It was easy walking because the river was so low and dry but no gravel bars as they are all covered in mud. I went to two different parts of the river as well as the feeder creeks and it was the same. Here are a few pictures of the little I was able to find: Some worn chunckasaur, petrified wood, pyrite sun (cool but common), a couple xiphactinus fangs, a decent mosasaur jaw piece, a piece of mammoth enamel, and a couple other oddities. 1. Some odd fish bone? 2. Horse Tooth? 3. No Idea. I would say fish fin but it doesn't have the flaky fish texture though. 4. Any idea what age and formation these shiny shells come from in the top left of this picture?

I have a mini fossil display setup at my workplace. This little display brings lots of attention from other employees. Most didn't know this area was under water in the past.
