  1. Mystery Shark's teeth

    Hello, These are also from our hunt in the Aquia formation of Charles Co. MD. Sharks of the world didn't give me much insight. The only species that I noticed where the enamel extends out on to the roots like this is the extinct goblin shark Anomotodon novus. I definitely have some teeth from that species I think but these are substantially different. These are larger, more robust and the have the cool extended enamel and bumps/cusplets on the shoulders of the labial side. Any thoughts?? (ruler in mm and squares 1/4") Kate
  2. Stratolamia striata?

    Hello, I am new here and new to fossil identification. These are shark teeth from the Aquia formation on the Maryland side of the Potomac. They come from Charles County. I have shark teeth of the world and so my IDs are based on that and the internet. I think all of these are Stratiolamia striata based on the grooves. Ruler is in mm and squares are 1/4" on each side. The last picture with only 2 teeth nearly touching seem different to me in that the striations don't extend very far up onto the teeth (unlike the others where they cover much of the crown. I am not sure if S. macrota also occurs at this site?? They are supposed to have striation only near the root. I have more from this trip but limited time so it will have to dribble out. Thanks for your time, Kate
  3. Hello All! I found this shark tooth at Purse State Park in Charles County, MD. Located on the Potomac River, these fossils are from the Aquia Formation. As a novice fossil hunter, I would love some help in identifying this tooth. Is this a Cretolamna sp. (appendiculata?) or Otodus obliquus? Thanks so much in advance! ~Natalie
  4. Purse State park tooth to ID

    A couple of weeks ago I stopped by Blue Banks, just north of Purse State Park MD. The Paleocene Aquia Formation is exposed there, and teeth and bones of a variety of species erode from the exposures and accumulate in gravel along the shore. Unfortunately the Potomac River was in flood stage, so the gravel along the shore was submerged despite the low tide. A driving rain storm did not help matters. I scooped gravel and passed it through a couple of screens, and recovered a handful of the usual small sand tigers and ray teeth, before calling it quits after an hour or so. The following was the largest tooth I collected by some margin. I don't see anything like it on Elasmo.com. There are no serrations and no cusps. Any suggestions for an ID would be most welcome. Don
  5. I found eight of these huge Cucullaea gigantea fossils yesterday! Anyone fancy a trade? I'm interested in vertebrate material, or really anything that is capable of swimming, flying, or crawling. Matt
  6. 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
  7. Tooth ID

    Hey everyone! I found this particular tooth at Purse back in March and have had no luck IDing it. Any ideas? I'm loving the colors on it though. The other side has an awesome dappled grey appearance.
  8. Otodus obliquus

    Three specimens acquired from a trade with @gavialboy Specimens are from an undisclosed location within the Aquia Formation linked to Purse State Park.
  9. I was able to spend a couple of hours out on the river today after work, nothing spectacular but I enjoy every chance I get to play in the water. I went to an area that I haven't been to since last fall, it amazed me to see how much things had changed in that time period. I ran into a box turtle on my way down to the river, love seeing these dudes. On my way back out I had to wade past a bush and got startled when a 3 foot water snake took off out of the bush. My box turtle buddy. Total haul Some of the better ones My favorite from today, love the curve.
  10. Unproductive Paleocene hunt

    I was going to go hunting with a relative at his property, but he was away. Having already driven to Annapolis, i decided to try to find another place to hunt. I found a place within the Paleocene Aquia formation. There was no macrofossils, other than a shell piece, which may not be a fossil (although I would then wonder how it got there, I was a long way from the water). There was a ton of these (ironstone?) Concretions in the sandstone. I'm breaking down some sandstone with water and manual labor, when the sand drys out, I'll see if I can find any microfossils. This is my first experience with microfossils, and I don't have a good microscope, so a magnifying glass will have to do. I also found two (oyster?) shell pieces on an eroding mound of sand, presumably a more recent (but still old, it's way above sea level so it's at least a few hundred or thousand years old) sand dune. They are worn, but I don't know if they somehow they got up there anthropengenicly, or if they are fossils. I'll use this thread for microfossils if I find any microfossils.heres some of the stuff I found, starting with the shells, the first is the one possibly from the Aquia.
  11. Thanks to Facebook I realized the 1 year anniversary of this hobby obsession was on July 2nd. I haven't been out in the past couple of weeks due to overdue chores around the house...I hate it when adulting gets in the way of having fun! Anyway, after 5 days off for the holiday weekend, I really wasn't looking forward to going to work today...especially since I had to cross the river to the Maryland side to take care of some things at my home base. As I was getting ready to leave this morning, I decided to throw a pair of shorts and my water shoes in the car just in case...I wasn't expecting to get out early but you never know. Well, I was glad I did since I was out of there within 3 hours...off to the river I went! I showed up just before low tide and quickly headed out. I wasn't expecting much after the holiday weekend, in fact, I was expecting a crowd when I showed up. I was shocked to find out that I was the only one on the beach...and the low 80s temperature and overcast conditions made it quite nice for collecting. Within 20 minutes I had found a croc tooth and an Otodus, I was pleasantly surprised. I kept moving along and in a particularly silty area, I spied a piece of a tooth. I reached down and grabbed it and was shocked to see that it was a Paleocarcharodon Orientalis! My first one! Happy dance!!! I walked a couple of miles and was pretty happy with the finds, it truly is a great place to take kids as everyone finds teeth there. Some in situ shots: I wish I would have taken a picture of this in situ...but I quickly took a picture when I saw what it was! Total haul: Paleocarcharodon Orientalis, front and back. Couple of Otodus. Croc tooth I'm thinking turtle on this...front and back pictures.
  12. Unlike the success that @WAHAMA90 had yesterday, we were not as lucky. There was hardly any beach to search when we arrived, the winds from the past couple of days had packed the water into the Potomac. After driving 90 minutes, we didn't let it deter us and went out anyway. We brought along a contractor trash bag to help clean up the river and unfortunately we filled that full pretty quickly with mostly recyclables. The shark teeth were not as easy to come by as the trash...and when we did find them, they were small. Funny moment of the day was when I found a decent Otodus tooth, I held it up to show my wife and it slipped out of my hands into the river. Oops! Well, on the positive side, I'll get to use my new digital microscope to check out the tiny teeth and we can honestly say that we did something on Earth Day. Total haul of teeth: A waterlogged knucklehead dumping the trash: Total haul of trash:
  13. Unknown Aquia Fm Teeth

    Finishing up trying to ID some finds from the Fall at Purse State Park in Charles County, Maryland. These presumably are from the Paleocene Aquia Formation. This is my only collecting trip there so far. I think that #1 is a crocodile tooth, #2 is a turtle scute, #3 is a claw or tooth, and #4 and 5 are fish teeth. Please school me Fossil Forum. More of #4 and 5 More of #3
  14. I went back to Purse today with my wife, you just have to love it when you play at the river in February and only have to wear a sweatshirt. We didn't find anything spectacular but my wife did find a Otodus frag that would have been absolutely spectacular had it been whole. The total haul, some nice glass today too. Otodus frag...this would have been a beast if it was whole! Pretty cool looking sand tiger. Croc tooth...found this sitting high and dry as I was walking fast to get to where I wanted to search at. I see you! Although it was warm today, there were some neat icicles hanging down.
  15. I met up with Boneheadz to do a hunt together at Purse and I'm glad that we did, nice to have a fellow tooth nut along for the hunt. Great day to be on the river too, pretty warm and the Potomac was extremely calm. We got to the river about 2 hours after high tide and headed out. We both went further downriver than we had ever gone before, scanning the beach and poking around the newly fallen matrix. I can't say it was a banner day for finds but as usual, the finds were consistent. After three hours of searching, we left the river with the tide still an hour away from being low...always next time! Here are my finds, Boneheadz will post on here later with his finds. My total haul. A first for me, a piece of matrix with a tooth in it. Otodus, too bad the biggest one was damaged. On the way back, I looked out over the marsh and spied an eagle's nest. I love seeing the eagles along the river.

  19. I got my weekend chores done early today and my wife asked what the tides were like today...after a quick check, we were on our way! You have to love it when the temperature was in the high 70's at the end of October! The water is still warm enough to wade in too, I was kind of shocked to see one lady out hunting for teeth in a bikini, I guess everyone was taking advantage of the unseasonably warm temperatures why they could. We didn't find anything super, the normal stuff for this area. I guess my favorite finds for today were the verts, too bad one was worn and broken.
  20. I had the honor of taking a friend that I had not seen in 30 years and his family, shark tooth hunting. He had been monitoring my Facebook posts about all the fun my family was having searching for them and asked if I would guide him and his family. We couldn't have picked a nicer day, mid-70s and sunny...and the river has not cooled enough to make wading uncomfortable, his daughter even decided it was warm enough for a swim! As usual, within seconds of hitting the beach they had their first tooth and a little girl was smiling ear-to-ear! I brought some screens for them and showed them how to use them but as I told them, most of the time you can find just as many by walking slowly and looking. We hit the tide perfect and the water was lower than I have seen it all year, I was itching to strike out and explore but I stayed close since I was the "expert" (term being used extremely loosely!). I wish I would have got some pictures of them collecting, despite driving 3.5 hours to get there, and having to repeat the trip when we were done, they were all smiles the entire time we were out collecting and they had Ziploc bags full of teeth, shells, and sea glass. I think I hooked them because they are already talking about taking their camper to Smallwood State Park and going again. As far as the finds go, nothing too exciting...after seeing WAHAMA90's report from earlier this week, I was amped up to find a paleocarcharodon tooth as well (of course, I'm always hoping for that one). We found the normal bunch of sand tigers and such, but my daughter brought me one tooth that she thought looked different...and sure enough it was. After looking at my ID book, elasmo, and Phatfossils, I believe she found a Pachygaleus Lefevrei (Extinct Hound Shark). Pretty cool find and equally fun researching it this evening when we got home! Our finds for the day...sorry, no cool Calvert Marine Museum ruler for reference! LOL! Pachygaleus Lefevrei
  21. Yesterday I received a box of fossil matrix from fellow forum member Otodusobliquus and I couldn't stop myself from spending a few hours looking through it. The matrix is from the Aquia formation in Virginia and I believe it is composed primarily of marine material. But one of the first fossils I found appears to be a tiny rib done. When I asked Otodusobliquus if he had ever found mammal material in this particular matrix he said he hadn't. But he also mentioned that the overlaying Nanjemoy formation did include mammal material and it was possibility that something from that formation got mixed into the matrix he sent to me. This leads me to ask is what I found truly a rib bone? What creature it might it belong to? The scale is in mm and I apologize that the pictures aren't as crisp as they should be. On of these days I will find a way to take clear pictures of my tinier fossils.
