  1. Potomac River - Lucky Otodus

    I was out kayaking on a creek on the Virginia side of the Potomac today to do some birdwatching, but in an area I thought might have some Aquia exposure. I did come across one small bluff face, with maybe maybe 40 feet of narrow beach, that I stopped to check out. After about 2 minutes, I looked down and found this guy. My best Otodus so far and still razor sharp! I did find a few more much smaller teeth and a decent ray plate fragment, but nothing special the rest of the day. But this tooth--plus dozens of herons, ospreys, eagles, and purple martins, among other birds--made for an awesome trip. I hope you enjoy the pix .
  2. Help with Potomac shark teeth IDs

    Hi, I made a few visits earlier this spring to the Potomac (Aquia formation) in Maryland and collected a bunch of shark teeth, most of which look like Striatolamia striata with quite a few likely Hypotodus verticalis as well. I'm hoping to confirm my IDs of a few potential Otodus obliquus and Cretalamna appendiculata teeth as well as get help identifying some others. The teeth in question are below--I'll include composite photos from different angles in reply posts. I've currently categorized teeth #1-3 as Otodus obliquus, #4-6 as Cretalamna appendiculata, and #9-14 as Hypotodus verticalis (based in part on the absence of striations). Teeth #7-8 look like something else to me--could they be Brachycarcharias lerichei? Thanks in advance for your help!
  3. hunting the lower Potomac

    I took a trip to the lower Potomac 4/29/20. I found plenty of fossils including this 1 15/16" C. Auriculatus, a 1 7/8" Striotolamia striata, a 1 3/4" C. Megalodon, And a 3/4" crocodile vertebrae. The Auriculatus and the meg were pretty worn. But I found all of these fossils two hours, and a big tooth is a big tooth! I'm happy to take them either way. The croc vert was a bonus.
  4. Trace Fossils from Miocene Potomac

    Hi, longtime lurker first time poster here. I was wondering if you guys can help me ID this concretion my family found years ago near Calvert. I believe it might be a trace fossil of some kind, possibly a burrow or tunnel. I have found similar types at Westmoreland State Park. I can upload pictures from different angles if needed. Any suggestions of what it could be?
  5. Potomac Paleocene Finds

    Hello, my son and I had a great time on the shores of the Potomac River in Maryland, USA yesterday. Found some nice shark teeth and also a few objects that may or not not be fossils. We’re hoping you could help. These two pieces were associated with the Paleocene Aquia formation 56-59 million years old. Here are 4 pictures of each of the two objects. #1 #2
  6. Hi. Like many, I am working from home. NJ has closed school for 5 weeks. It’s only been a week and I’m going crazy. Plus I am a financial planner so my days have been challenging to say the least. TFF has been a great escape to take my mind off of everything. I also thought I would take the time to really nail down some IDs on these teeth from the Potomac. I thought maybe I can get some confirmation on my IDs and use them to compare with the others that I have collected All the teeth are from Douglas Point. Thank you for any feedback, be safe, and everyone keep posting great content!
  7. Unknown Fossil--Please help identify

    I found this fossil several years ago while I was looking for shark teeth along the bank of the Potomac. The exposed cliffs in the area are part of the Nanjemoy formation, and the fossils I find are usually Miocene or Eocene. I have no idea what this fossil is (Maybe a tooth?). I figured that I would finally get around to posting this in hopes that someone on this forum can help identify it for me. More pictures available upon request. Thanks, Christopher
  8. Aquia Formation bone fragment

    Hi all, I found this chunk of bone at Purse State Park this November. It is from the Aquia Formation, which is of Paleocene Age. I was wondering if it could be identified to either crocodile or turtle, considering that these are the only two bony vertebrates that exist in large amounts in this formation. Or, of course, it could be nailed down to chunkosaurus status considering that it is relatively worn and isn’t very large. Thanks in advance!
  9. Potomac finds from weekend

    Had nothing else to do yesterday so went to a spot on the Potomac. Found bunch of teeth and some nice bone. Ones a rather large piece about 6 inches long and 5 wide. Another nice half of a vert that's broken. Fav two are the porpoise teeth? Water was awfully cold and the wind wasn't cooperating so only looked for a hour. Then had to get back in truck and warm up. Temps near water was 45 and inland it was 59. Quite the difference and wasn't dressed for that. Not sure what the big piece of bone is from or the vert? Anyway, nothing great just better than doing nothing on a Saturday!
  10. Vert and bone from Potomac in Virginia help

    Hey guys, little help on these 2 pieces of bone. Ones a simple vert that's broke in half. Woulda been really nice. About 2.5 inches across. Any ideas? Shark? Dolphin? Other big slab of bone that's got 2 ridges that I can tell on the outer side. Whale? Some other sort of animal? It's about 5.5 inches long and 4 wide. Found in the Potomac if that matters on Virginia side. Tons of small bone and teeth but just curious what these may have belonged too. Any help greatly appreciated and thanks.
  11. Ray plate or what?

    Found this on the shore in the Potomac with tons of other ray fossils. Is this from a ray or something else?
  12. Potomac fossils ID

    I recently bought this display case of fossils from the Potomac at a flea market. Being from Illinois, I'm not familiar with these fossils. Can anyone help IDing these or at least directing me to somewhere I can look them up myself?
  13. I have to say that today was a fun day, I took @Darktooth and his family out for some fossil hunting along the Miocene areas of the Potomac. We had a beautiful day for it, just wish that the clouds that had been forecasted would have showed because it became extremely hot out there! Nevertheless, we persisted and spent about 5 hours looking for fossils and we were all wiped out by the time we got back. I know that Darktooth will be posting his own report, the following is just what my daughter and I found. I had a great time with you Darktooth, I hope you and your family enjoy the rest of your vacation! Total haul of our "small stuff" Nice "doorstop" whale vert A nice hastalis, really the only tooth I found Crab, I just started to look for these. Never really had the eye for them before. My daughter found this piece of fish jaw with a tooth in it. She really didn't know what she had but thought it looked neat and put it in her bag. I found this fish vert in a chunk of matrix A couple of small shark verts A little ecphora Now for the really cool find, definitely a trip maker and my best find this year...three attached verts that have been tentatively identified as marlin. Dr. Weems will get a look at them on Monday so I may get an updated ID then.
  14. Scallop

    From the album Virginia Miocene

    Chesapectin nefrens Westmoland County, VA Choptank Formation Middle Miocene C. nefrens is fairly common in the Choptank Formation, but the level of sculptural detail preserved in this particular specimen just blew me away when I gently brushed off the loose sediment.

  16. Maryland Adventures

    I finally was able to take the family down for a short trip to Maryland this past weekend in hopes of finding some shark teeth. Despite the heavy crowds everywhere we went we able to have a fun filled weekend. We started off Saturday morning and were the first on the beach at Flag Ponds Nature Park. The tide was coming in but we still managed to pick up a few teeth. Our best find there was a nice mako, almost and inch. We stayed there until lunch, took a break and went off to Matoaka cottages for the afternoon/evening. We didn’t find nearly as many teeth there but were able to find a few nice hemi’s, the biggest being right around the 1 inch mark. Sunday morning we got up and made made our way over to Purse Park. We got there around 11am and were met with a full parking lot. I was a little discouraged knowing it would be crowded but we went ahead to the beach. Wow was I glad we did! In about 3 hours of searching time we managed to scoop up around 200 teeth! Most of the teeth were very small but we did find a few nicer ones there as well. Overall I’d consider the weekend a complete success! This was our first trip with fossil hunting as the specific focus. Despite the heavy crowds everywhere we went, we still managed to bring home over 200 teeth, at least 50 ray plates, and numerous other miscellaneous fossils. I can’t wait to go back!
  17. Hi, We are doing a unit on geology/paleontology in our homeschool with the fossils we find. I was wondering if anyone knows the difference between the Aquia and Nanjemoy formations. I know wikipedia is not perfect but I am not an expert and it lists them as separate formations albeit both from the Paleogene. I have read Paleocene/Eocene border for the Aquia formation. Is that correct? The Nanjemoy formation I had not read about before today. Is it just the same thing on the Maryland side of the River instead of the Virginia side? Thanks for the help, Kate
  18. Purse state park bivalve?

    Hi everyone, During a trip to Purse state park in Nanjemoy MD, I found an odd "rock" while looking for sharks teeth. It appears to be shaped like some kind of mussel or other bivalve. Any ideas what it might be? Unfortunately I don't have anything to measure it with, but it is approximately 2 1/2 inches long.
  19. Miocene Mystery Shell

    Okay, here's a weird one for any shell people out there. Found this on the Potomac's beach where the cliffs have Eastover, St Mary's and Choptank FM exposures. At first, it was a blob of clay with what looked like a hinge showing at one end. I chalked it up to oyster or mussel. Brough it home, cleaned it up most of the way and said, "What the heck?" The texture is really strange. It's convex where I would expect it to be concave. It's lumpy, but not heavily sculptured. I took it to some people who were more familiar with the spot and/or knew something about vertebrates, in case my mollusk assessment was totally off. No, looks like invertebrate of some kind, they said. I've identified and catalogued over 70- species from the cliffs, pouring over the same references for countless hours. There are a few approximately the right shape, given how broken it is, and have similar parallel growth lines, but the texture and lumps???? And that weird ridge 1/2 of the length from the beak? Multiple shells overlapping? Again I say, "What the heck?"
  20. Real Stumper

    Okay, I concede early on that this may be abiotic, but I just have this gut feeling that it's not an accidental pattern. I found this on the banks of the Potomac River in Virginia. The geology there is mostly early to mid-Miocene clays with a Pleistocene terrestrial bog iron layer on top of 40 to 80 ft cliffs overlooking the river. All fossil-bearing. This looks like clay, but I'm not positive that it is from the Miocene layers. There is a row of tiny lumps all about the same ship and almost in a contiguous line. One is just a little offset.
  21. Mystery Scapula

    I found this scapula this weekend along the Potomac River in Virginia. It's a vertebrate. That's all I know for sure. Most of the cliff next to the beach where I found it is miocene marine, but the very top is pleistocene terrestrial. The grid is in inches.
  22. Maryland Paleocene 2/17/19

    Headed out to the potomac this morning and man was it nice out. Hit low tide and made my way to the cliffs, which all fallen right now btw. Found some nice sand tigers today’s and some smaller beaten otodus. Highlights of the day were a nice little croc tooth and a croc vert which is a first for me. I don’t seem to find much bone in the Aquia formation.
  23. Hello everyone, I will be visiting the Washington DC area, and want to take a trip to the Potomac to hunt for some shark teeth. Can anyone suggest a good area, and possibly some gear to wear this time of year? I normally wear a wet suit and waterproof boots for this sort of thing and stay relatively warm, so I'm not too worried about the cold. I am looking for a spot with easy access, and preferably not private property, unless someone is willing to let me search on their land. I have never been to the Potomac before, so any suggestions are welcome! Thank you!
  24. Looks like a claw

    I found this while hunting for shark teeth at Purse state park in Maryland. It looks like a claw, any help would be appreciated.
