I found this mammal tooth in France, Chalons-Sur-Marne, while searching for shark teeth. I should be (late) paleocene. Does anyone have an idea which animal?

I have bought this crocodile vert on a fossil show a few months back and i was wondering if someone could identify what species it came from? I'm not even sure if it is a crocodile vert but it looks like one but since the person who i bought it from didn't know much about crocodile bones it could be something else too. it measures 71.6mm long and 52.0mm wide. for Americans its 2.80" long and 2.04" wide. it was apparently found in Morocco in a Paleocene formation but i have no name of the formation and neither of the exact place where it was found ( i know this is probably gonna

Interesting shell found at Douglas Point, Maryland which should be Paleocene Aquia Formation. Didn't see an obvious match anywhere online, any ideas?

North Carolina Cretaceous angel shark cartilage/vert., fish skull cap, mosasaur tooth, and more!
fossil_lover_2277 posted a topic in Fossil Hunting Trips
Collected these in North Carolina this weekend. Angel shark vertebra w/ fossilized cartilage, fish skull cap, mosasaur tooth, soft shell turtle fragment, worn Otodus tooth, goblin shark teeth, crow shark tooth, bull shark tooth, and not sure what the smallest shark tooth is. These come from a mix of Cretaceous Tarheel and PeeDee formations and Pliocene Yorktown formation.- 1 reply

From the album: Fossil Amber and Copal: Worldwide Localities
Roughly 200g of small (≈1g) nodules and runs of amber from the West Open Pit Mine in Fushun, China; the mine was closed in 2019, but small pieces of amber are still recovered from coal found in the gangue piles; it is separated from the matrix by mechanical action and immersion in large vats of saltwater solution, and recovered with netting as it collects at the surface. This material is hard, takes a high polish, and is often shaped and drilled to make beads. Its chemical and spectrographic signatures indicate this amber is derived from a cupressaceous source.© Kaegen Lau

Upper Paleocene Lamniforms (Mitsukurinidae and Odontaspididae) ID from Chile
terminatordiego posted a topic in Fossil ID
Hello to all guys!!!, I would like to ask again for help in the ID of some teeth. I´ve been searching in a local university's museum for teeth of the original strata (Upper Paleocene), and I have found a very interesting set of boxes containing a bunch of different teeth, all labeled as "Scapanorhynchus sp.", maybe existing a missidentification. The question would be if any of you guys can ID the pieces and how to differentiate the Scapanorhynchus sp. from Striatolamia striata or Sylvestrilamia teretidens, the options I´m leaning for the ID of the teeth. I would also li -
Hi all. This past Thursday I made it out to Douglas Point (Paleocene, Aquia Formation). I found the usual assortment of sand tiger shark teeth and some goblin shark teeth too. Unfortunately, finding an Otodus in this formation still eludes me. First is a picture of all my finds. What I'd like some ID help with are the vertebrae, the two bone fragments, and the crocodile tooth. The last tooth is an interesting one. Looks like a Hemipristis serra tooth to me, though I didn't think they're found in this formation. I included an in-situ photo with the characteristic Douglas/Purse grav

This past Thursday, I made a trip out to Douglas Point along the Potomac. I enjoy going in warm weather like anyone, but going during the winter has its own merits. Cool, crisp air, fewer people, possibly some more unique finds. I was the only one on the beach for just about the whole morning and afternoon. Although a little chilly, the right gear made it no problem at all. The trail down to the beach is a bit run down. Lots of broken and collapsed trees covering the trail. I found quite a few sand tiger teeth. I only keep the larger ones now that I find and leave the

Hello All! As you can see by the title of my post and the plethora of pictures to follow, I have been quite busy... busy fossil hunting that is! Since New Years I have been averaging at least one trip per weekend which is a good fix to distract myself from the less-than admirable weather (I just want spring!!!!!). This whole week is off for me since I'm off on Spring Break and that means I can go out hunting during the week to avoid the crowds which is always pleasant to get the beach to yourself. Also with the turn of the season and somewhat "warm" weather we have had I was able to launch my

I went to my local spot, Henson creek, and decided to check things out. I arrived and found some stingray and sand tiger shark teeth. I stumbled upon what I thought was bone, it totally turned out not to be bone. I am very happy about this find, even though it was the only thing of significance found today it doesn’t matter. It’s so perfect. It will probably be a while before I find another otodus tooth that size again! Here’s the photos: The total length is over 1.5 inches, and would probably be hitting 1.75 if complete. What

I was fortunate to find an excellent Palaeocarcharodon orientalis tooth this morning at Douglas Point (Paleocene, Aquia Formation) in Maryland. I thought it was an Otodus obliquus at first but then I bent down and saw the serrations. The tip is a little dinged, but it has a solid root, shiny enamel, both cusplets, and those classic ragged serrations. At a little over 34 mm long, it's quite large for the site. I also found my first section of fossilized croc jaw (also just over 34 mm long) today, which still has two teet

A few weeks ago I found this bone fragment on the Potomac at a Paleocene site. It has a distinctive indentation which I thought might allow for an ID. An initial suggestion was a turtle bone, maybe a peripheral bone where a rib ending would attach. But I am open to any other ideas. I understand there may not be enough to go on. Thanks for looking!

I made it out to the Potomac yesterday in Maryland and finally found a 2" (almost) Otodus obliquus tooth! IMG_5728.mp4 It's worn and missing both cusplets unfortunately (have to have a reason to keep looking, right?), but this has been near the top of my Maryland bucket list fossils. It's tad less than 2" (1.91"/48.6 mm), but also very wide (1.38"/35.1 mm) with a nice chunky root. I'll round up. Here it is next to my previous largest Otodus personal find (1.59"/40.4 mm), from February. The new one is

Hey guys, I'm back from my trip out at sea. It was a very insightful and unforgettable experience. Learned a lot about the world around, and myself as well. anyways, enough about that, I went out to Douglas point yesterday and although it was a very short day, it was also extremely productive. Which included some pristine sand tigers, a perfect 1 1/2 inch croc, and a killer Otodus. Here’s everything good I found: (Idk why it goes in sideways but there’s the total of everything found).

I was hoping to get some help identifying this Paleocene sand tiger shark tooth from the Aquia Formation. I tried to compare it to the examples on Elasmo but I know that there is a lot of variation in teeth and I am by no means an expert. I thought it looked like a Striatolamia but I did not see any striations- maybe they were worn off. Any help would be greatly appreciated. Thank you so much and happy Thanksgiving!

Help needed in fossil sharks ID - part 2 (Upper Paleocene of Chile)
terminatordiego posted a topic in Fossil ID
Hello to all of you guys, a couple of weeks before i asked for help in relation with some shark teeth, and the help indeed was very nice! A couple days before i was back in field trip and found some more teeth from the same strata, and would need your help for the correct ID (hopefully at species or genus level), you guys are awesome!!! Here´s the list of the fossils (each step of the ruler is 2mm): 1) A tiny tooth with very small roots and 3 denticles, the central and main one is triangular and very oblicuous 2) A tooth with very triangular cusplets and -

After going several weeks without fossil hunting, due to weather, schedule, etc., I finally made it out to Douglas Point (Paleocene, Aquia Formation) in Maryland this morning on a very pretty, cool autumn day. My first fossil find of the day was a small piece of ratfish plate. Below is my first shark tooth of the day (a sand tiger, like the vast majority of teeth found here). By the standards of this site, the quantity of shark teeth was low today, but they were in better than average shape, which isn't a bad trade off. Many appeared to be fres

Took the relatively short trip down to Purse State Park last weekend and had quite a bit of success! Best find was certainly a fairly large chuck of what I think is turtle shell, along with a very much alive turtle that rested with us for our lunch before returning to the water. The dream of finding anything marine mammal or a somewhat complete ray plate remains for next time!

Hi everyone! I tried this one on the FB group without any luck, hoping for some ideas here. This was found in Purse State Park (now Nanjemoy WMA, I think) on the shoreline, which I've read is Paleocene in age. This is by far the most interesting tooth I've found there so far, but I haven't seen an obvious match in any of the guides I've looked at. Does anyone have any ideas?
