  1. Mystery Bone Fragments?

    So, I know bone fragments are notoriously hard / impossible to fully identify. Unfortunately, they are my favorite things to pick up I am happy with most of my collection remaining unknown, but there are a couple pieces I feel may have more identifying characteristics? I'm very new to identifying fossils so please let me know if its something obvious or if they aren't even bone fragments to begin with! I will describe each piece and then post photos below. 1. Found at Douglas Point, Nanjemoy WMA in Maryland. Less than an inch long, black, grooved, shiny, looks a lot like many of my other little "unidentifiable" pieces except for a small section of serrations on one edge. Are they teeth? They all seem to be one form, if that makes sense, not individual teeth like shark teeth. 2. Found at Douglas Point, Nanjemoy WMA in Maryland. This one is the most "bone-looking" of the three, but I've read that the only large vertebrates in this area and time period were turtles and crocodiles. Its a strange shape, the bottom is rather concave like some kind of joint, or maybe a scute? I have no idea, I even wondered if it was a modern bone but it has the solid / rock-like feel of a fossil. 3. Found at Flags Pond, Maryland, part of the Calvert Cliffs formation. This is the most confusing to me. I can't even decide if its supposed to be a bone fragment or not, let alone a fossil. Its not black like most of my other bone fragments and is very porous but in a different way than the other pieces. It has the heavy rock-like weight and sound to it though. My first thought was weird rock, then weird coral? Then I thought, I don't know, maybe a bone? I've seen pictures of fossil bones online with similar color / texture but the shape is... strange. I'm very unfamiliar with aquatic mammal anatomy- which is what I'm assuming this would be if it is indeed a bone and not some strange rock or coral. I'm not looking for species identification or anything specific, but any thoughts or info on these guys would be nice to hear, especially so I can compare to what I find in the future. Love the shark teeth but its really cool to find things that aren't sharks too. Even just confirmation or not that they are fossils to begin with haha. Also let me know if I should add photos from different angles / more detailed shots, I didn't want to put too many images in one post. Thank you in advance and maybe I will post some of my less confusing collection soon
  2. PG county

    Ok I think I’m gonna be posting fairly regularly on this site from now on. So I’m a DC native, which means that the amount of fossils in dc are mostly sparse. However, neighboring PG county is a hotbed for all types of stuff! In the future, I’ll post my dinosaur stuff from here (still on my bucket list to find a tooth). In the mean time, I’ve just recently came back from southern PG county and I came away with some pretty cool stuff. The shells that come out of this creek are to die for. They’re some of the most intresting I’ve ever seen! But what I’m really excited about are the shark teeth! I couldn’t believe that just 10 minutes from the border of DC, you could find shark teeth here! I’m gonna go back here on Saturday hopefully to go find more teeth. I’m most interested in gathering the silt from this site and searching for micros because my micro collection is lacking. Anyways, here’s all the finds from this place. Oh, and I’m getting the smallest of my teeth from that fine clay down there, believe me my camera cannot capture how small these teeth are they’re like 1 mm big!
  3. Potomic Paleocene Teeth ID Help Request

    I recently took a trip to Purse State Park, MD, U.S. and found this tooth fossil that I cannot identify. Because of the location (Potomic River), I assume it is Paleocene era. The fossil is 13 mm (0.5 inches) across. The pictures are of each side. Please help me identify this fossil.
  4. Over the weekend, I decided to take a trip to the Santa Monica mountains for a hike and a fossil hunt. There was information about the site in "NEW UPPER PALEOCENE SPECIES OF THE BIVALVE PLICATULA FROM SOUTHERN CALIFORNIA" by Richard L. Squires and Louella R. Saul, which contains Late Paleocene marine life. This is probably a good opportunity to warn fellow hunters that it is not a smart idea to go quickly up a canyon in near 100 degree heat. Under the early afternoon sun I walked too quickly and made the mistake of not pacing out the hike! Despite plenty of water intake I was still lightheaded by the time I found the site, and a little dizzy. I rested in the shade immediately and ate the lunch I had packed while cooling off. Then I got to work examining the scree for a while before heading down the canyon to my sweet AC. The spot: Unfortunately, not much caught my eye this time. Marine fossils I took home: While splitting, these concretions popped out. Anybody know what they are? I've been enjoying rearranging them. Lower left may contain a fossil, I'll send closer pictures if anybody wants to see. As well as this, which I believe is one of the above split open. It has a ringed, deviled egg quality. I found a similar piece in the Badlands of SD and was surprised to come across this here. If there's a technical name I'd really like to know it! Do pack plenty of water if you hunt around here for the next month or so, you'll be doing yourself a big favor. And go slow!
  5. Marine Paleocene Poop?

    One of my boys found this item while we were hunting at Douglas Point on the Potomac today. I think it could be a coprolite, maybe from a croc, but I am not experienced enough to know. Can anybody say yeah or nay?
  6. 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.
  7. Amelia Island, FL Vertebra

    Anyone provide help with an ID on this vertebra? Try as I might, as a serious amateur I've hit the limits of my abilities and could use the collective wisdom. Assumption is that this is a vertebra. Found on the beach on Amelia Island, Florida. I find fossils there routinely and live there part of the year. I find this Forum invaluable to gain knowledge.
  8. Stumped on Amelia Island, FL

    Longtime lurker, first time poster seeking ID assistance. I've collected for years and have hundreds of pieces from the Atlantic Ocean beaches of Northeastern Florida. I'll post a vertebra shortly that I'd love some help ID'ing, but I've never seen anything like the two pieces below that washed ashore post Hurricane this summer. If someone tells me they are geologic and not fossil, I wouldn't be shocked but they are stone, not shell, and have the same color and density as the other fossil bone shards I find on Cumberland Island in Georgia, Amelia Island in Florida and nearby. The larger piece is about 1.5 inches long, and the smaller is half that size.
  9. Aquia ID Help

    Recently took a trip to Douglas Point and found this odd shaped piece in matrix. Not sure if it is anything or just some sort of concretion, appreciate any help! Thank you

  11. Paleocene Plants

    I have tried without confidence on my IDs for these finds from Sweetwater County, Wyoming. I suspect Sycamore?? It would be great to get these labeled properly!!!! 1. 2. 3. 4. 5.
  12. 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.
  13. Help with Paleocene tooth ID

    Found this on a recent trip to purse state park, tried to look online for similar teeth or bone and no luck. I’ve seen something similar before on the forum but for the life of my can’t remember where or what it was. Thanks!
  14. Hello again fossil gurus! I went to per state park again today and found over 80 shark teeth and shark tooth fragments! It was really great. I also found these three little bits which I thought were intriguing, particularly the middle one. Is it a bone fragment!? I apologize for the picture with my hand, but it was the one that seem to catch the texture inside the best. Any ideas on what the others are? They were all found near the waters edge. Thanks so much!
  15. Alabama Paleocene Fish Tooth

    Once again I need help with an identification, this time a fish tooth, from the Upper Paleocene Bells Landing Member of the Tuscahoma Formation in Monroe County, Alabama. I apologize for the graininess of the photo, but I had to capture it with my iphone as my digital microscope provided no details or contrast of the tooth. I am hoping that one of the Aquia collectors might recognize it to perhaps genus. The most obvious feature is a central keel on one face of the tooth. Length of tooth is 6 mm. Mike
  16. Is this Enchodus?

    Believe this is enchodus?
  17. Hi, I bought this tooth last year and was wondering if anyone knew if it is authentic? It is about two inches long. TIA
  18. Alabama Shark Tooth help

    All In the process of looking through screened material from the Upper Paleocene Bells Landing Member of the Tuscahoma Formation, I came across this small 3 mm shark tooth. This deposit located within Monroe County, Alabama is equivalent in age to the Paspotansa Member of the Aquia Formation in Virginia. I searched the Aquia section on Elasmo.com but could not find anything similar. I don't know if this is a juvenile or an adult tooth but the most noticeable feature is the deep nutrient groove. I am hoping one of the many shark tooth experts here on the forum might be able to give some insight into what it is. Left: Lingual Right: Labial. Thanks Mike
  19. 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!
  20. 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.
  21. 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?
  22. 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 .
  23. Maryland shark tooth

    Hi, I was wondering what these two shark teeth are. Any ideas? They were found in Maryland at purse state park.
  24. 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.
  25. Before quarantine took effect, I had a chance to visit Purse State park. I normally frequent Brownie Beach, but the recent cliff collapse forced me to try some other spots. I was also interested in finding some much older fossils from the Paleocene formations along the Potomac. I found tons of turritella gastropod molds, and many smaller lamnid teeth. Some of the larger ones I found were pretty easy to identify as Striatolamia species, most likely S. macrota that had slight surface wear from being washed around in the Potomac. Most teeth from this location seem to be similarly eroded, and almost all my S. macrota specimens seem to be missing their telltale crown striations. I found some nice looking ones I found, all approximately an inch in length and with a hint of blue coloring. Towards the end of the trip I also stumbled upon a likely pathological lateral tooth, probably another Striatolamia. It definitely caught my eye, and I really liked the weird curvature of the crown. This one was about half an inch in length, and although it might not be easy to tell from the photo, it had a much stubbier tip that was not the result of chipping or erosion. Anyways, I just thought I'd share an interesting find from last month since I'm losing my mind in quarantine. It sucks not being able to go on hunts when the weather is so nice, but I hope everyone is staying safe.
