  1. First hunt at Potomac River

    Went on my first hunt at the Potomac River on Wednesday. It was great weather and had a blast. It was high tide but was able to get a productive 2.5 hours in before I headed back to NJ. I was fortunate enough to meet another TFF member in the parking lot Bjohn170. Still have to go through and ID everything but enjoy the pics.
  2. Hello! I actually found both of these Miocene fossils years ago at Brownies Beach (Calvert Cliffs Maryland, USA). When I found the tooth, I thought it to be a worn, unidentifiable rooted Cetacean tooth (so I never researched it) but saw a fossil hunting trip report this morning where a similar fossil was identified as a sperm whale tooth so I'm hoping this might be the same case. As per the other one; it looks a little different from the normal mammal bones i find here so I figured I would post this one too. As always, all help is greatly appreciated! -Frank
  3. Brownie’s Beach No Trespassing?

    I haven’t been to Brownie’s Beach in a while and thought I’d take a day trip. When double checking my route online I notice some tv news stories about a cliff collapse there in January that the fire department responded to. No one was hurt, and looking at drone footage afterwards the beach seems to have way fewer collapse piles than last year. So I didn’t think too much of it and showed up there this morning. Once I made a right at the water after walking down the trail, I was greeted with a large sign saying; Danger unstable cliffs ahead. Any persons beyond this point will be considered trespassing. There were also three metal poles in the sand like they were going to put up a fence. At this point I was pretty annoyed and didn’t think to take a picture. Sorry. There were foot prints in the sand that went right by the sign, but I wasn’t trying my luck. So I went to Matoaka Beach for the day. I wanted to check it out anyways so I took the opportunity. I had a pretty good day and will post a few pics of some stuff I’m unfamiliar with another day. I have a few questions about the signage and if you can answer any of them please chime in. And if you have a question jump in. When did this sign go up? Can the town or police really not allow people in the area? Considering Maryland’s property laws and the high tide line, can anyone actually fine you? Is the sign there more as a deterrence and/or release of liability by the town? Any input is much appreciated. Basic64
  4. Amazing day yesterday! @sharkdoctor and I spent all day at the Calvert Marine Museum’s collection sorting through and cataloging pieces of his collection either loaned or donated to the Museum. When I say amazing fossils, I mean it. Crabs, birds, whale material, possibly a new species of seal, teeth, turtle plates, and more. @sharkdoctoris a really cool guy because he focuses all on adding to science and not just trying to grow his own collection. Plus, he’s so informative! After completing the cataloging of his collection we proceeded to catalog some of Bretton Kent’s world class shark tooth collection. The incredible John Nance took us through the museums archives, showing us the only Hexanchus from Calvert, 3 inch makos, Gomphothere Teeth, rare species of shark, a whole crocodile, and other innumerable fossils that would be any collectors dream to have. Thank you John Nance, @sharkdoctorand the whole fossil community for building this up.
  5. Flag Pond / Purse Park

    2 of the 4 deer that like to eat my bushes. Sorry, now to the tooth. Going through numerous teeth I have, trying to organize them. This one from flag pond. Carcharhinus? Or hammerhead?
  6. Matoaka Cabins, Maryland

    Searched matoaka beach today. Lots of shells, but I don’t collect them. Not as much luck as Brownies, but not bad. I believe that I got my first fish tooth.
  7. Miocene Shark Teeth #2

    These teeth (as with my other post) are from a Miocene site in Maryland USA, Calvert Cliffs area, specifically Chesapeake Beach (Bayfront Park)- Brownies. I have tried to group and identify them. Do you agree? Thanks Row 1: Sand Tiger Carcharias sp Row 2: Cow shark Notorynchus cepedianus Row 3: Carcharhinus (I don’t know species) Row 4: Lemon shark Negaprion eurybathrodono
  8. Hello, I have been doing some fossil hunting at Bay Front Park (Chesapeake Beach) -Brownies- in Maryland USA and have been trying to group and identify some of the teeth I found. I believe these teeth are Miocene and my guesses are as follows- what do you think? Thanks Row 1: Physogaleus contortus Row 2: Galeocerdo aduncus Row 3: Hemipristis serra
  9. Here are some Nautiloids that I collected from the Eocene, Nanjemoy Formation of Maryland. I believe that they are Hercoglossa Tuomeyi. I’ve found lots of fragments but these are the larger, more complete specimens. Most of the outermost shell material is gone with the exception of the large specimen back, right which still has most of it. The large specimen center, back measures 12”x10”x6” and weighs 35 pounds. I about broke my back lugging it more than a mile off the beach. I’m not really sure that the small specimen on the stand in the center, back is the same species as it does seem to have different features from the others. Marco Sr.
  10. Last year I discovered a baleen whale fossil along the cliffs of Calvert cliffs park. Tomorrow it will be getting excavated. However I broke my leg just before Christmas so I am looking to see if anyone can video the excavation for me as I cannot attend. I’m hoping to get a video and some good pictures I can share on here. Please feel free to message me as I’m anxious to see the excavation process. I just wish I had better luck so I could attend and assist in the excavation of what I found. Anyone willing to help is super appreciated !!! Thank you
  11. Here are three more Riker mount displays that I just put together with my macro specimens from a site in Maryland with both Eocene and Miocene formations. The first 16”X12” display has shark specimens with Miocene shark teeth above the shark vertebrae and Eocene shark teeth below the shark vertebrae. The bottom Eocene shark teeth are mostly Otodus aksuaticus with a few Otodus auriculatus (for size reference the largest O. aksuaticus is 3"). The top Otodus teeth are Otodus chubutensis (for size reference the largest O. chubutensis is 3.5"). There is also a Miocene Parotodus in the top middle of the display. The second 16”X12” display contains both marine and terrestrial mammal specimens, bird specimens, reptile specimens, bony fish specimens and two bivalve shell specimens. Some of these specimens come from the Miocene like the two peccary teeth in the bottom right and some definitely come from the Eocene like the sea snake vertebrae in the bottom left and middle. The third display (8”X12”) contains both Eocene and Miocene ray including sawfish specimens (for size reference the large partial eagle ray barb, which is in two pieces, is 6.5" total length). This display also contains at the bottom two medial Eocene ray pavement teeth, Leidybatis jugosus. Marco Sr.
  12. Here are three more Riker mount displays (8”X12”) that I just put together with my macro specimens from the Miocene and Pleistocene of Virginia. The first two displays contain Miocene crab specimens in concretions. My sons and I have probably several hundred of these crab concretions. Unfortunately the quality of these specimens isn’t like the great crab specimens that come out of the state of Washington but they are still interesting to find. The second display also has a few borrows. The third display contains some miscellaneous specimens like petrified wood from Pleistocene bog iron of Virginia, Miocene terrestrial mammal teeth including a piece of a Gomphothere tooth, bony fish specimens like opercular series bones, tilly bones and sturgeon scutes, and some bivalve shell internal casts. Also in the display, bottom far right, is the only piece of a burrfish mouthplate that I’ve found in the Maryland/Virginia Miocene. Here is another 8”X12” Riker mount display that I just put together with macro specimens from the Miocene of Maryland and Virginia. This display contains some of the very first fossils that I ever collected dating back to the 1970s. In the early days of my collecting I only separated my macro fossils by age/time period and not by formation or location also. So I’m not sure of the location that a lot of these specimens were found at. Most are from the Miocene of Maryland. However I do remember that the two dark gray Otodus megalodons were found by me on the same day diving at Governor’s Run Maryland and that they were my first megalodons ever collected. I also remember collecting the ocean going sunfish jaw at Plum Point Maryland and the thickest sperm whale tooth at Stratford Hall Virginia. Marco Sr.
  13. Brownies Beach 1-15

    Went to Brownies for the first time Wednesday. Met up with @searcher78 and had a good time looking stuff. It is completely different then what we have in Jersey. The cliffs are really amazing. Enjoy the pics. Appreciate any feedback on the pics. Thanks as always. what could have been a nice Mako my first hemis ever! front and back of what I think is a piece of cow shark?
  14. It was a nice day for shark tooth hunting with another TFF member. I was hoping for larger teeth, but it was mostly small teeth.
  15. Unknown

    Don’t know what this is, but I kept it because it looked cool.
  16. Bone or Shell?

    Turtle shell? Can’t get good light right now.
  17. Bayfront park 1/11/20

    A couple hours of sifting and surface collecting, found a nice Mako, a couple Snaggeltooth and a handful of small teeth. Also came away with a small porpoise tooth and porpoise rib, vertebrae, and Epiphysis disk fragments.
  18. Douglas Point, Maryland

    Nice day for another hunt. Fish bones and a small crocodile tooth.
  19. Flag Pond, Maryland

    Stopped at Flag Pond today since the weather is nice.
  20. For years I’ve had my macro fossils in drawers and my micro fossils in gem jar displays. Recently I’ve started putting some of my macro fossils in 8”X12” Riker mounts. Below are the Riker mounts that I now have. I’ll probably put together at least twenty of these. Below are two Riker mount displays with specimens from the Paleocene Aquia Formation from the Potomac River in the Liverpool Point, Maryland area. This display contains in the top crocodile vertebrae, a couple of crocodile leg bones, and two crocodile coprolites. I have larger crocodile vertebrae but they are too large for these Riker mount displays. Then a row of crocodile teeth (for size reference the largest partially rooted tooth is 2”). I have over 200 crocodile teeth from the area but the vast majority are fairly small. Then on the bottom there are turtle shell pieces and a crocodile scute. This display contains in the top ray dental plates and a ray barb. I have a lot of very nice very small ray dental plates but the larger ones tend to be damaged/beat up. Ray barbs are not really that common from the area. The middle has a few Otodus obliquus teeth and a partial vertebra. The day I found that partial vertebra, a person that I took to the site for the first time, found a complete, perfect one of the same size. For size reference, the anterior O. obliquus tooth is just less than 3”. I have over 700 O. obliquus teeth from the area but the vast majority are water worn and/or have damaged root lobes, cusplets, tips etc. I believe that these sharks ate a lot of turtles which took a toll on the teeth. At the bottom are a couple of chimaera mouth plates and a fin spine. I have at least 110 smaller chimaera mouth plates in my gem jar displays. The next two Riker mount displays contain specimens from the Eocene Nanjemoy Formation of Virginia. I posted one of these awhile back here on TFF but I’ve rearranged it as I’m now putting more of my specimens in Riker mounts. This display contains on top a few of the larger coprolites that I still have from the Nanjemoy Formation. I’ve already donated over 20,000 of these to the New Mexico Museum of Natural History and Science. I’ve accumulated another 30,000 since my last donation in 2015. Then there is a row of sand tiger teeth two inches and larger. Then there is a row with additional sand tiger teeth and two Otodus obliquus. O. obliquus are not common at all from the area. I’ve only found five in over 165 trips to various sites in the area. Then there are two sawfish rostral spines/teeth and a sawfish vertebra, and a ray mouthplate and medial tooth with several ray partial barbs. On the bottom are three associated fish vertebrae, a small fish jaw, fish spine, and then two fish teeth. This display is a work in progress. I’m putting some of my larger reptile specimens in it. The bottom rows have two turtle lower jaws, turtle shell and a turtle bone. I have lots of other turtle shell pieces so what’s in this display is only a representative sample of what I have collected from the area. The next row contains sea snake vertebrae. I have over 100 of these so I’ll add a few more to this display. My largest, 1.5“ thick won’t fit in this display. At the top are three rooted crocodile teeth, a partial crocodile scute and a small crocodile vertebra. At some point in the future I will post more of these Riker mounts as I finish them. I’m also thinking of putting together a number of artificial shark tooth dentitions and mounting them in Riker mount displays I have several hundred thousand shark teeth from the Nanjemoy so I should have most of the positions for a number of different shark dentitions. Marco Sr.
  21. Chimera - Calvert Museum

    I gave the chimera fin spine that I found at Douglas Point to the Calvert Marine Museum. They had mouth pieces and a cephalic hook, but no fin spine. I haven’t checked out the museum in years. It has a very nice fossil exhibit.
  22. Fossil Sites in Maryland?

    Hello, I am in Maryland (near Annapolis) and hope to take my 9-year-old son fossil hunting. He really enjoyed our hunt in Pennsylvania (Beltzville) last week. I have heard of Calvert Cliffs (any advice?) but would also be interested in other sites. We could drive to sites in southern PA, northern VA or DC. Thank you in advance for any suggestions.
  23. Anyone having any luck this winter so far along the Potomac? Found bunches of sand shark teeth so far. Tides been high lately haven't been able to do anything this past weekend. Just checking to see if anyone has been finding anything good.
  24. A little brisk to start the day.
  25. Fossil ID needed

    Hi everyone, I was doing a beach cleanup on Sunday along the Port Tobacco River, & I noticed this little rock sitting next to an old beer can. It is 3 cm wide at it's widest point. The whitish grey color made it a challenge to photograph, so I added a slight wash to it. Any help with an ID would be greatly appreciated. I looked at many images of worms last night, but I didn't see anything with the same shape or length, & without knowing the age of the rock, I am not sure how to identify it. While it is whited out in the middle, when I look at it under a magnifying glass I can see that the horizontal lines extend through almost the whole length of the ovalish shape. This photo was magnified 2x. Thanks for looking!
