  1. So, I found this today in the Paleocene Aquia Formation of Maryland. Obviously it can't be an ammonite, because they were already extinct. It's a Nautilus steinkern, right, not some sort of gastropod? Thanks! Matt
  2. Heeding advice from members here I decided to stay away from Brownie's and the cliffs due to the recent flood of rain that we've been getting (it's even sprinkling today) and headed to one of my favorite spots, Purse State Park! I stayed close to the entrance because by the time I got there the tide was already coming in, and I wanted to avoid the cliff-ier areas. The swimming snakes, cliff faces full of bees, and millions of floating spider webs acted as a decent deterrent as well! I actually walked a bit to the right and then on my way back walked past the entrance because of how high the water had come in... but as if it were meant to be I found my biggest tooth after I walked beyond the entrance! There was noticeable new material from the cliffs falling and down towards Douglas Point looked nearly impassable with a rather large cliff fall down that direction. And now for the teeth! I have one question about a tooth that I can't really identify. I am still new to the hobby and I am getting better about not going to Fossil ID every time something pops up but with not much experience sometimes that is hard! Only my second Otodus (maybe? I still am having a hard time with the Cretalamna's vs. Otodus) ever, still looking for that big one: My run of the mill finds, accompanied by a handful more that I didn't bother to take pics of: This one I'm a bit stumped but I'm sure everyone hear will have no problem with ID... it's fairly large so that's why I don't think it's just a Tiger or something similar but it's missing the cusps that would make it another species (if it were even supposed to have them). Any help would be appreciated! With finals finally over and a new kayak in tow I hope to have better and more in-depth reports this upcoming summer. I want to see if all of this armchair Google Earth imagery analyst pays off... haha. Just wanted to thank everyone on here because I've gathered so much knowledge even though I may not post much. I am still super new! Hopefully this is just a small start to the fossil hunting that this summer will bring! Almost forgot to mention that Purse is located in the Aquia formation of the Paleocene. Thanks for reading!
  3. Hello, I found this leaf fossil north of Glenrock, Wyoming in the Paleocene Fort Union Formation. Can anyone help me ID this fossil? The fossils were plentiful! Thanks in advance!! Greg Kruse, Casper, WY

    From the album MY FOSSIL Collection - Dpaul7

    Palaeocarcharodon orientalis tooth Oued Zem, Morocco Paleocene (61.7 to 55.8 Million Years Ago) Palaeocarcharodon, also known as the pygmy white shark, is a genus of sharks in the family Cretoxyrhinidae. Palaeocarcharodon orientalis is the only species of this genus. These sharks lived in the Paleocene, from 61.7 to 55.8 Ma. Teeth of Palaeocarcharodon are triangular, labio-lingually compressed, with quite irregular serrations and serrate lateral cusplets. They can reach a size of about 3–6 centimetres (1.2–2.4 in.)

  7. Pathological Tooth?

    This tooth was found on my most recent trip to Purse State Park. I believe it is a Mackerel Shark tooth, Cretolamna. I think this may be my first truly pathological tooth because it does appear to be deformed. The crown of this genus does not typically slant to one side so much as this one does. Also, the crown is twisted rather than flat, much like the crowns of Physogaleus contortus. The thing that most leads me to believe it is pathological, however, is one of the cusps. The first cusp seems normal, but the other is twisted at a 90 degree angle and seems pressed against the crown. Can I get any confirmation that this tooth is in fact pathological? Also, can I get an ID as far as species goes, or is Cretolamna sp. the best I can get? Thanks in advance!
  8. Purse State Park 03/26/18

    I'm back! A long spring break presented me with the opportunity to go out on a few fossil trips. I just haven't gotten around to posting until now. But here we go! After finding over 600 shark teeth in one day at Purse State Park, how could I not go back? With the stress of school completely absent from my mind, I went down to the park along the Potomac River for another day searching for Paleocene fossils. I arrived early, as I always try to, and I was the only one there when I arrived. Instead of heading to the left of the entrance as I did on my first trip, I decided to start by going right. After all, that was where I found my beloved Otodus tooth! This ended up being a good decision. For about the first hour, I wasn't finding teeth quite as often as my first outing, and this was a bit discouraging. However, as the sun rose higher into the sky, I started finding teeth left and right. I believe I was the only true fossil hunter at the site for the whole day; only a family or two with their children showed up for about an hour each and headed out. The one other person I did meet, however, was a man who was searching not for fossils, but for driftwood. Apparently he makes some pretty awesome sculptures with the wood he collects. He was pacing the beach with a heavy chainsaw. I originally thought he may have been after sharks teeth as well, but he assured me that "the teeth are all yours, buddy!" A matter of seconds after he said that, I picked up a small tooth that looked unlike anything I'd found at Purse before. Holding it closer to my face, I saw serrations on the blade. I knew it could only be one thing: Palaeocarcharodon! I was jumping with joy! It was a very small tooth, but very pretty. I was climbing through a big clump of fallen trees and logs when I found it. More proof that looking in obscure areas is worth it! The tide was rising. I kept further from the entrance, finding more of the usual Sand Tigers along the way. I made it to the duck hunting post, and turned around. Although the tide was reaching high up the beach, I thought going to the left would still be worth a shot. I walked a little faster than usual to reach the cliff area before it was too late to access them. I hardly found anything on my way there, and by the time I did reach the cliffs, the tide was almost completely engulfing that section of the beach. So I made my way back towards the entrance. The tide was reaching higher and higher up the beach, and I realized that I would likely have to leave soon because there would be no more beach to hunt on. So I made one last quick run to the right, because that seemed to be the side I was having much better luck with. With the palaeocarcha as my undisputed "trip maker", I would have been more than happy to have only found some more Sand Tigers on the last run. But Purse State Park was feeling extra generous that day. Searching high up onto the beach, I looked down to see a beautiful gold-colored Otodus tooth sitting right out in the open. It wasn't very large, but it was complete with both cusps and all. A true beauty. And if that wasn't enough, literally no more than 12 inches from that tooth I had just picked up was another big shark tooth! But this one wasn't an Otodus. No, it was ANOTHER Palaeocarcharodon! And this one was much bigger than my first! I couldn't believe that I found TWO of the most sought after tooth from the Paleocene Era. And with that, I left Purse State Park with a box filled to the brim with fossils. Overall, this trip was amazing! Perhaps even better than my first outing to Purse. I highly recommend going to this site if you love finding sharks teeth, and lots of them! Hoppe hunting!

  10. Hello. I recently took a trip on the Potomac River south of Washington to a Paleocene site. Nothing too exciting for the most part. Lots of small shark's teeth, two smaller broken Otodus teeth. I did, however, find two oddities. Both appear to be bone, one has "ripples" in the surface reminding me of turtle shell. the other has dimples that somewhat resemble a crocodile scute, but not exactly.. Any help would be appreciated.. Thanks!! drobare
  11. Finally made it out to Purse State Park, now known as Nanjemoy Wildlife Management Area, yesterday. I had read that there was no beach to speak of at high tide, but wow! Low tide yesterday was at 11:15. We got there at 12:30 and there was already almost no beach! If only we'd gone when @RCW3D went two weeks ago! The air temp was a balmy 50 degrees, but the water temp, not so warm. Did that stop us? No. Did we get frostbite? Maybe. We weren't expecting to have to go wading when we left the house 3 hours earlier, so warm, waterproof shoes were not with us. We went barefoot on the chilly sand, wading occasionally, then warming our feet again. That way, we had warm, dry shoes and socks for the trip home. The only fossiliferous exposure we found, admittedly not going far north as we'd have had to wade waist-deep, was between the two trail openings. There is an exposure of the Aquia Formation that reaches about 10 feet above beach level there. The cliffs further north are much higher, but empty, so not a lot to look at along the walls. That's okay, most people don't go to Purse to look at the walls anyway. There were plenty of teeth to be found on the beach until our toes got numb. I dug a hole in the sand in front of the fossiliferous exposure and to my joy found some blocks of matrix buried there after they'd fallen from the cliffs. There was also a complete oyster hanging in mid-air from a fine tree root, three feet above the ground, that I managed to slide off without so much as nicking the root bark. Ha! As an added bonus, I got to enjoy the forsythias blooming on the beach! There are almost no fossil shells on the beach. They are so punky in the cliffs that they just disintegrate when they are exposed. However, I am optimistic that when my blocks dry out I'll have some nice specimens that I can eek out with some dental picks, paleobond, and patience. I also brought home a backpack full of micro matrix to sift. Never know what might be lurking in there!
  12. 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 kayak for the first time this season this past weekend and I hope to make good use of my kayak. If any other members would like to hunt sometime feel free to message me (also anyone who wants to take me out on their boat I would take that offer too! ) I'll post a thread of my recent trips along with my more favorite finds and some fossil ID help. I'd also like to add that I have successfully taken over our family dining room and turned it into my own private fossil collection (sorry mom) and I love how it shows the true variety of teeth you can find as well as the differences in locations and the fauna you can find. The paper towels are all from recent trips and the plates are all from previous trips to Stratford Hall which I divided into plates for each different species.

  15. Paleohypotodus?

    Hey all, Hope all my fellow East Coast dwellers are holding up alright after the storm. We got hit pretty hard with snow in Northern VA. Anyway, this tooth was found at my Purse State Park trip a few months back. It looks quite different from the majority of the teeth I found on my trip. I used fossilguy.com to compare it to common fossils from the Aquia Formation, and it looks very much like a Paleohypotodus rutoti tooth. Can I get any confirmation on this ID or is it something else? It is slightly over 1/2 inch, but that's with a dinged tip. It has a distinctive U-shaped root that is very wide and flat when viewed from the side. The most unique things about the tooth, however, are the cusps. They are very worn down, to the point where they appear as nothing more than a couple of black lumps. The crazy thing is that it looks like there are three on each side. I believe this is typical of P. rutoti but it's hard to tell because the pictures online have sharper cusps. Does anyone have an ID for this one? And if so, I'd love to know a little more about the shark itself, because it is seldom mentioned online. All I know is that fossilguy has it listed as a "Mackerel Type Shark". Thanks in advance for help with the ID. Hoppe hunting!
  16. I was able to head to the Paleocene area of the Potomac for a few of hours today, glad I did. I was heading to work, I was quite shocked to see the water was already extremely low even though low tide was supposed to be 6 hours later, I confirmed the tides when I got to work...a strong west wind had pushed the water out and I was set to have some prime time beach time with extra low tides. By the time I was able to slip out of work, I made it to the river about 2 hours before low tide...the water was already lower than I had ever seen it before; this is when I realized that I had too much of a good thing! I kept zigzagging back and forth between the waterline and the old waterline. I finally gave up the zigzag approach and decided to walk the waterline going and the old waterline coming back. The finds were less than what I was expecting but I'm not complaining either, I wish I cold have spent a few more hours out there. My trip maker was my second ever Paleocarcharodon orientalis, worn and much smaller than my first one, I almost discounted it when I originally spied it because I thought it was a broken tooth. A little voice inside my head told me to check it out and I was pleasantly surprised when I picked it up. Total haul.

  17. Strange paleocene mollusc

    What is this strange mollusc? I found it in a creek in the Acquia Formation in Maryland, just outside of DC. In case the photos don't make it clear, this appears to be cylindrical, with a flat base, opening up to a flower-like, open crown. Any thoughts on what it is or how to prep it? Thanks, Matt

  21. Purse State Park // 2/18

    Had a busy weekend after visiting Brownies Beach on Saturday 2/17 and then back on the beach at Purse SP on Sunday 2/18. Nothing spectacular from this trip, but was able to find a decent Otodus kicking in the wash which is always a good day for me. While sitting on a chunk of cliff-fall as I was eating lunch I found 5 teeth sticking out of the matrix and they were SHARP! I need help to ID the blade I found. It was sticking out of the formation and is fossilized. I don't believe it is from a shark due to the symmetry, but it looks like it may be some sort of fish tooth of sawfish rostrum. Lots of broken sandtigers to be found and the bald eagles were enjoying the warm weather. Once the wind died down it was beautiful outside and the beach was packed with visitors as my friend and I left with our bags of goodies. u ID? love how perfect the cusps are on this micro
  22. Here are some micro finds from a recent trip to a Paleocene site on the Potomac river. The drum tooth is the first drum tooth I have found and it was my second find of the day!
  23. These teeth were found along the Potomac River in Western MD, in the Aquia formation. I am having a tough time finding information on teeth from this location but I believe these are possibly Pigmy White teeth (Palaeocarcharodon orientalis). All six show signs of serrations, but there are other teeth from the Paleocene that might look similar? I need help identify them and don't want to mislabel them in my collection. Also I found these two smaller teeth with serrations on one side but they seem unlikely to be Pigmy Whites. Any idea what they are?

  25. Fossil ID?/Recent Trip

    Hello! First time posting on the forum so any help is good! I recently went hunting for a few hours and was able to have a decent day by myself at the water. I need help to ID the two teeth I posted up-closes of. The fragment would've been a sweet tooth if whole and I wish the other tooth had the other cusp! I believe both teeth are from the same species of shark, but I have never found a species like this. I have never heard of Carcharocles angustiden being found in the MD/VA area and the area I was at I believe is mostly early Miocene so I was thinking it might be a Carcharocles chubutensis??? I also found some decent Makos and a very nice Barracuda tooth which I thought was pretty cool.
