  1. Large rock shape due fossils?

    Hello was in Potomac river area hiking saw this rock, about 5 feet or more. On one side it had shape which looked like due to fossilized remains or head or pelvis of a animal or just water carved it? Video and full size pictures here https://drive.google.com/folderview?id=18z9JWGLYdPZBwCrd3VbRlqZ44GjANR1k
  2. Otodus obliquus?

    I found the tooth below this morning at Douglas Point (Aquia Formation, Paleocene) in Maryland. The cusp is fairly narrow, it's missing one cusplet and the other is small and/or worn down. But between the prominent lingual protuberance and what looks to me like a small bourlette, I'm getting an Otodus obliquus vibe. What do you think? I also found a tiny Cretalamna appendiculata -- just over a quarter of an inch.
  3. I’ve recently bought some fossil shark teeth online to expand my collection beyond the local Maryland fauna (Miocene from the Calvert Cliffs and Paleocene from the Potomac River/Aquia Formation), and it occurred to me that perhaps there are some forum members who would be interested in sharing some of your finds or extras in exchange for mine. The things I have to offer are shown below—mostly fossil shark teeth and a few other things. These aren’t all perfect, but there’s a good variety, including some less common species. I’ve collected most of these myself and have also listed a few purchased teeth for trade. If there’s something that interests you, hopefully we can help each other build out our respective collections. I have particular interest in adding Ptychodus sp. and Cretodus sp. teeth from the Cretaceous to my collection, but I’m open to a broad range of offers. U.S. trades are likely easiest for shipping, but I’m happy to consider international offers too. Thanks for looking! Quick summary of shark teeth available for trade by species (also see photos below): Miocene from Calvert Cliffs - Alopias latidens (2), Carcharhinus sp. (5+), Carcharodon hastalis (1), Galeocerdo aduncus (2), Hemipristis serra (4), Negaprion eurybathrodono (5), Notorynchus cepedianus (1), and Physogaleus contortus (4) Paleocene from Potomac River/Aquia Formation - Anomotodon novus (2), Cretalamna appendiculata (2), Palaeohypotodus rutoti (3), Paraorthacodus clarkii (1), Striatolamia striata (4+), and unidentified sand tigers (4+) Miocene-Pliocene from Purchases - Carcharocles megalodon (1), Carcharodon hastalis (2) I. Shark Teeth Available for Trade A. Miocene shark teeth from the Calvert Cliffs (unless otherwise noted): Alopias latidens (thresher shark) - both pending Carcharhinus sp. (gray sharks) – I also have others available. The tooth on the far right is from a Miocene exposure in Virginia (Westmoreland State Park). Carcharodon hastalis (white shark, predecessor to the great white) Galeocerdo aduncus (tiger shark) – The smaller tooth on the right is from a Miocene exposure in Virginia (Westmoreland State Park). Hemipristis serra (snaggletooth shark) - tooth A is pending Negaprion eurybathrodono (lemon shark) Notorynchus cepedianus? (sevengill cow shark) – This is most likely N. cepedianus though it’s a partial so I don’t know if it can be definitively ID’ed. Physogaleus contortus (tiger-like shark) B. Paleocene shark teeth from the Potomac River/Aquia Formation: ** I’ve done my best to identify the various sand tiger shark teeth below, but I may have made some mistakes. Anomotodon novus (goblin shark) - both are pending (though I also have others) Cretalamna appendiculata (mackerel shark) - tooth B is pending Palaeohypotodus rutoti (sand tiger shark) – I am pretty sure these are all P. rutoti due to the presence of basio-labial folds (see this elasmo.com page), but I could be wrong. Paraorthacodus clarkii (no common name shark) - tooth is pending Striatolamia striata (sand tiger shark) – I have others available too. - teeth A and D are pending Other non-striated sand tiger shark teeth – I’m unsure of the species on these; some may be Hypotodus verticalis. I have others available too. - tooth C is pending C. Purchased shark teeth available for trade: Carcharocles megalodon – This tooth was collected by a diver from the St. John’s River in Florida and measures a little over 2.75” slant height. I believe these are both Carcharodon hastalis – They are from an estate sale and their original collection location is unknown. They measure 1.7” and 1.2” slant height, respectively. II. Other Fossils Available for Trade A. Miocene from the Calvert Cliffs: Ecphora gardnerae? (gastropod) – If this is E. gardnerae, it’s also Maryland’s state fossil. Drum fish teeth Ray crushing plate fragments – The two v-shaped ones on the left are Aetomylaeus sp. and the other two may be as well. I have others available too. - plate B is pending Fossil corral – I believe these are Astrhelia palmata. I have others available too. Fossil sand dollar fragments – I have others available too. B. Paleocene from the Potomac River/Aquia Formation: Ray crushing plate fragments – I have others available too. Turritella sp. steinkerns/casts – I have others available too.
  4. Westmoreland State Park

    Hello, I found this some time ago at Fossil Beach in Virginia. Can anyone help me identify what bone this is and what animal it may belong to? Thank you! 3 Monkeys Mama
  5. Hello there fossil experts! I'm a total newbie and just went on my first fossil hunt --a couple hours at Purse State Park. I found a bunch (like 60!) shark teeth, mostly tiny but i'm still thrilled. But i also found some things that look like fossil shells, and one thing that looks like fossil scales, that i was hoping you could help me ID. The first picture is what looked to me like fossil shells, but are they? are there fossil shells at purse state park? most of the online discussion of finds there seems to be of teeth, rays, and mouth plates and doesn't mention shells so i wasn't sure. They were mostly found about halfway between the water's edge and the cliffs. the things in the second picture (with two large items) were found basically at the water's edge. Are these fossils? if so, what are they? i thought the one on the left sort of looked like underbelly scales. I also found two small mystery objects which are in picture 2, below the tape measure. Any ideas what these are? they are smooth and seem heavy. Thank you so much!
  6. Eocene Snake Verts?

    Out collecting the other day at an Eocene site on the Potomac, one of my kids came up with THREE cool verts! We think they may all be snake verts, but we wanted to get a second opinion. Any thoughts?
  7. hello the west side of the Chesapeake Bay is famous for vertebrate fossils at sites like Calvert Cliffs has anyone found or know or finds of vertebrate fossils on the EAST coast of the bay? thanks
  8. Went on a kayak trip on the Potomac for Father's Day with one of my kids. We spent a couple of hours around some paleocene spots. I found yet another lucky otodus right off the bat (sadly, one cusp missing). Between the two of us we then picked up a bunch of smaller teeth and a fair number of ray plates. We also got 3 croc teeth, including a nice fat one I found on my very last pass. I think we also got a small coprolite in there, but not 100% on that, and a chunk of turtle shell. All-in-all, not a half bad Father's Day trip!
  9. I took my kids yesterday for a quick hike out to Douglas Point to get some exercise and check out the Potomac. I wasn't expecting much because the tide was still pretty high and the water a bit muddy. But conditions were better than expected, so we were able to look around a bit. About 10 minutes in, I spotted a really nice little otodus in a submerged gravel line just below one of the bluffs. (Very tricky to see these guys, sometimes, against the dark sand.) It's in great condition and looks like it just came out of the bluff. We poked around as the tide went out for the next hour and came up with some more smaller teeth, some plates, and a few pieces of turtle shell, but nothing as nice as that first tooth. Anyway, it was a fun time and kept the kids busy for awhile! I was happy to find a decent tooth under tricky conditions. Enjoy the pics.
  10. Purse Beach Find

    Hi, friends! First time poster here. We found this interesting one at Purse Beach, Maryland. Any thoughts. Thanks! PurdyFamilyFossils ... and please forgive my lack of professional photography skills.
  11. Potomac - Fossil Wood? (Solved: Turtle)

    Hey guys- I was kayaking yesterday near Blue Banks and stopped for a rest and, of course, to see if there was anything interesting lying around. I picked up this piece of what I thought could be fossilized wood, but I'm not sure. It is definitely mineralized, has some very faint slightly radiating lines on the "top" and has a clear pore structure in cross section. Any ideas?
  12. 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 .
  13. 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!
  14. 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.
  15. 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?
  16. 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
  17. 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!
  18. 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
  19. 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!
  20. 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!
  21. 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.
  22. 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?
  23. 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?
  24. 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.

    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.
