    Crocodile Vert? and what species?

    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
  3. The cover story in the current (June 2022) "Scientific American" magazine is about Paleocene mammals with nice artwork of Ectoconus, an early placental mammal that has previously received very little mainstream exposure. It's a nice summary of what has been learned about groups of mammals from the time between the extinction of the dinosaurs and the evolution of nearly all mammal groups we know today. The author, Steve Brusatte, has also written a new book on mammal evolution (published earlier this month), "The Rise and Reign of Mammals: A New History, from the Shadow of the Dino

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.

    Fushun Amber (Guchenzgi Fm., 56-50 Ma)

    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.

  8. 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

    Douglas Point Finds ID Confirmation

    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

    Some Fun Finds at Douglas Point

    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
  11. 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 thought it was a bone…

    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
  13. 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

    Paleocene marine turtle bone?

    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!

    Chunky Otodus

    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

    Aquia crawl

    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). Front (or backside technically) of the best teeth
  17. In the September 2021 issue of "Natural History" magazine, there's an article, "The Trans-Saharan Seaway," by Devin Reese, Robert V. Hill. and Leif Tapanila. Anyone who collects fossil shark teeth knows Morocco and other parts of northern Africa were submerged by an inland sea as recently as the early-middle Eocene but there was also an arm of the sea that cut south all the way from what is now Algeria to what is now the Gulf of Guinea. The article summarizes the work of a team of geologists and paleontologists across a ten-year period in the early 2000's. It reviews a number of fossil find

    Paleocene Sand Tiger Shark Tooth

    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!
  19. 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

    Douglas Point 10-17-21

    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
  25. 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!
