    My Birthday Calvert trip

    Hi Everybody, Last week, I decided to go to the cliffs for my birthday, and I resolved to get up earlier in the morning to get something I had not found before. My equipment was the standard loadout, sifter, shovel, waders, sunshirt and hat. Along with a one strap bag that I would wear for the 1st and last time. (The strap would slide in front of my chest and neck everytime I leaned over and ducked down. it also broke halfway through my hike) When I arrived I didn't find much to write home about save for a whole shark vert. But when I waded out into the decently clear water I managed to find a vert and a couple ribs. After a couple hours and a ton of smalls, the tide came up. I noticed how high it got and realized it would be a slog to wade back, so I elected to wait an hour before the long haul back. I noticed a bunch of wildlife while I was out, I saw frogs, a weaver spider, herons and a Bald eagle with some osprey. On my way back, I felt discouraged by how choppy the water was and the lack of stuff I was finding ( Pro tip: the choppy water will help you find more stuff after it passes). That and the strap falling off of my bag was annoying. But midway through my Slog, I saw it: out of the corner of my eye I saw something bluish Grey and bigger than a shell. "There's no way" I said as I leaned over and saw the fragment of a tooth bigger than any other I found so far. I was tired, exhausted, and shaking. But here it was, my White whale, the tooth I was looking for after 3 years in the palm of my hand. It just turned dark as I arrived to my car. I think I pushed past being tired. My gear was soaked, I was soaked, but I did it. I Finally got my Meg. Breakdown of the finds below: 297 specimens in total. Starting with teeth, I think this is Hammerhead. Next up is the Meg. Measures 1.74 on the diagonal. Which I estimate would be a 2 inch tooth if whole. I'm excited bc this tooth is unmistakably a megatooth, there's nothing else it could be! Rib bones, this one looks interesting to me bc there looks to be a possible blood vessel groove, and a dissension on the middle right. Could that be a muscle attachment scar? Longer rib Whale vert

    Calvert Cliff bone ID

    I found mostly mollusk remnants on this last trip to Calvert Cliffs, but I did find this more intriguing find. I'm a former Austin, TX fossil hunter, so the switch over to Maryland hasn't been all that different (considering both were shallow oceans) except that in Maryland it's a lot more difficult getting access to fossil areas. What do you guys think? Eurhinodelphis? I did see a while back a full skeleton was removed from the cliffs. Thx

    Calvert Cliffs Multi Trip Finds

    These are from multiple trips between 2022-2023. all from Calvert cliffs, each trip has something unique I would like assistance in identifying so for convenience's sake, I will refer to the items in alphabetical order relative to the numerical trip order. 1A 2B etc. Trip 1 1A pretty sure it is a crocodile tooth, Thecachampsa sp? 1B this is a bone that i found on the beach, im not sure if it's a cetacean atlas or skull fragment. but it's got this weird hole in it on one side. 1C clearly a cetacean vert. probably a juvie dolphin. i think so bc it doesn't have any fused epiphysis. id like to know what part of the spine this would have been on the animal. 1D maybe the wing of a vert? 1E is this anything? or just concretion 1F biggest fossil I've found yet by far! this massive chunk of whale jawbone. I am going to make a separate post in fossil prep to see about the best ways to clean it. 1G maybe a rib? i believe its a bone of some sort. i need to paleobond this one back together. Trip 2 2A definetely a tooth of some sort. not sure if its a croc or a cetacean since the enamel is worn 2B maybe a rib? or vert wing? 2C I think this might be a turtle shell, because its texture is not pronounced enough to be a cookie fragment. 2D maybe a skate osteoderm? 2E 2F 2G Sand tiger shark 2H crab claw with some sort of borehole? any other comments or ideas are as always, appreciated!

    Are these scales or skin?

    Hi all: First, thank you for this forum! I really appreciate the responses. If anyone can help identify this I'd appreciate it. There were huge storms in California that brought down a lot of fossils from the cliff. I think this is one. Thank you!
  5. In late August, I went fossil hunting in Maryland, near the Calvert Cliffs formation, and found this tooth. I am wondering what type if shark this tooth would have come from. It measures around an inch long.
  6. Lucky to have lightening strike twice on the Potomac… 4.25/5.25

  12. Hi All, It's been a while since I have posted, let alone gone collecting but I just had a really good trip down to the Matoaka Beach Cabins in St. Leonard, MD. Here you can pay $5 ($10 on weekends) to access their beach which gives you about 1/3 of a mile to explore. I went down on Tuesday the 14th since I had some time off from work. It coincided with an extremely slack tide which directly led to many of my best finds. No shark teeth unfortunately, except for two pieces that were just roots with the toothy part broken off. I did however clean up on Ecphora sp. and Cetacean bones as well as a couple of mollusks that are hard to collect. A view of the beach with a fall from last year. It's about 1/2 the size it was last year and will likely be even further reduced by this time next year. Such is the life cycle of the cliffs. A view of the cliffs straight on. I'm not positive but I believe the shell bed exposed is the Shattuck zone 18, Drumcliff member of the Choptank Fm. Above that is zone 17 which is the St. Leonard Member. Both are Miocene in age. I'm still digging into the ID of what I found so please correct me as needed. A specimen of Dosinia sp. with some of the original shell coloring preserved. I'm not yet sure who this is, but they are hard to collect intact as the matrix is very crumbly and so are the shells. I suspect this is from the St. Leonard Member of the Choptank F,. This is a small razor clam and is another tough one to collect because the shell is very thin so it doesn't erode out intact. Typically it just falls apart. Ecphora sp. in the water that you could see thanks to the slack tide. I found a bunch of these in different sizes and surprisingly intact. I found 3 Cetacean vertebrae in the shallows of the low tide with the largest one about 4" across (6" of you include the "wings") Oh yeah, then there was this odd limb bone, but I posted more pics of that over in Fossil ID. I also managed to get over to the Potomac and walk along the banks at Purse Creek Park. Nothing spectacular, but it was still fun. Maybe if the weather cooperates I can get another trip in before it gets too cold. Thanks for viewing! Dave
  13. First I suspect is a worn ray tooth but am a bit thrown by the shape. The second I really have no clue on. Would be very grateful for any help with these. Thanks!
  14. When I tap this with metal tweezers, it feels at least partially mineralized, but it has also changed color to a chalkier, lighter tone since it dried, which leads me to think it can't be fully mineralized. Would this be the case with a very young fossil (say Pleistocene)? Is there any Pleistocene material at calvert cliffs?
  15. Found this today at calvert cliffs. The only things I could think of that it could be were a juvenile porpoise or crocodile tooth. Anyone have any thoughts?
  16. Made my second ever trip to Calvert cliffs (went to Calvert cliffs state park). The first trip last year was fun, but I didn't really find any of the big shark teeth that I couldn't find near home at Big Brook in New Jersey. This time I did much better. Stopped on the way home from a family vacation and finally got some of the things I'd been hoping for. Still no megalodon teeth, but maybe next time! Got only a small handful of shark teeth, but was lucky to get two very nice hemipristis teeth, one of which was in absolutely stunning condition. Also got so many stingray teeth I started giving some away to other hunters on the beach, and a large pile of bone fragments. Most interesting find was probably a very small, curved, translucent, conic tooth that looks like either a juvenile crocodile or perhaps porpoise tooth to me.

    ID please

    Hello! I’m new here and just found something (first ever!) today at the Withernsea beach in UK. No idea about anything, please help Thank you. If you need more pictures, just let me know.
  18. Yesterday I found this piece of vertebra near the Calvert Formation at Calvert Cliffs Maryland. It seems to be a "cookie" but is taller than online pictures show and haas a strange belly button shape with a pattern in the middle. It is roughly 3-4 inches wide and 1 inch tall. Does anyone recognize this fossil?
  19. Dear TFF members, Ive taken a photo of all the shark teeth that I am having trouble identifying. Could anyone help point out if I got any ID's wrong? These were all found at Calvert Cliffs, MD. Top 3 rows near Choptank and St Marys Formation and bottom half underneath Calvert Formation. 1. Snaggletooth (serrations are similar on both, the first one has a strange enamel color) 2. First two are white sharks, probably plicatilis? Third, I have no clue 3. Requiem shark tooth (just suspicious because I've never found a tooth in the area with that color) 4. Posterior tiger shark teeth 5. Worn down tiger shark? 6. Snaggletooth front tooth piece 7. Cow shark (is this pathological? ive found a couple of other cow shark teeth and none of them have opposing edges) Thanks for the help, James
  20. I know it has been said before, but anyone collecting along Calvert Cliffs, always be careful. I was out yesterday and saw 2 different falls. One was giving warning of it coming, with a number of small clods trickling down. I did not hang out in that area and kept well away from the cliff. About 45 minutes later I heard the sound of a fall and saw it come down. As I was kayaking home I saw another section, about the size of 2 minivans, come down. That was in an area that sees a lot of collectors. Also, when I was out yesterday the bay was absolutely full of sea nettles. It looked like the scene from "Finding Nemo" with the jellyfish swarm. Those actually sting, and they were so thick anyone in the water would encounter dozens of tentacles very quickly.
  21. Yesterday (January 2nd) was only my second trip to Calvert Cliffs. I'm pretty new to fossil collecting, but thanks to the wonderful advice and reading the greatly informative posts from members such as @Darktooth @FossilsAnonymous @WhodamanHD @racerzeke @KimTexan and @paxhunter I had a lot of success and it was a much more productive trip than my first. Below is a brief summary and some pictures of what I found: I woke up, put on a few layers clothing, and had my coffee at 3:45am. After my morning pipe (tobacco...I actually make briar tobacco pipes as a hobby) I got in my pre-loaded truck and headed south at 4:45am. I made good time on the drive down as I hit 695 and got around Baltimore before the morning rush. At 7:10am I arrived at Brownies Beach and pulled in to a parking lot with only two other cars in it. After putting on my full waders, I grabbed my sifter and headed towards the beach. I planned this trip so that I could arrive midweek and get there early enough to catch some of the low tide (tides times were not friendly this week, but I start teaching classes next week so it was this week or wait until spring). Sunrise was at 7:24, but there was more than enough light to see...and what a sight it was. When I entered the beach area the tide was way, way out. I couldn't believe how far out it was, as it was past two small sandbars (if I get my GoPro video edited I will post it). Once I was on the beach I headed south towards the cliffs. I hurried through the beach area because I wanted to be by the cliffs with the tide so low. I know I missed teeth along the beach, but I wanted to get to the cliffs with the tide being so far out where I could hopefully find some larger teeth than what are common at the beach area. As I neared the end of the beach I ran into one woman who was there just to relax and walk on the beach. We said good morning and I knew who one of the two cars in the parking lot belonged to. Once I went around the point and turned my eyes close to shell line and started looking. Because of all the wonderful advice from this forum I had a much better idea of what I was looking for and how to best look. After a few minutes I had some ray plates, very small teeth, and my first ever vert. It wasn't even 7:30 and I knew it was going to be a good day. As I made my way down the shore line that I figured had been pretty well picked over from people being off over the holidays, I remembered a forum member saying 'you need to look in the places that others don't'. I approached a fallen tree that I remembered from my first trip a few weeks ago, and with the tide being so low almost the entire tree was exposed so I got down on my hands and knees and started looking at some of the gaps between the tree and sand...then it happened. You know when you day dream and picture yourself finding a great tooth or fossil? Well that's what happened as my eyes saw a pristine Mako just laying there (pictures below). I know its not a huge tooth or a meg, but to me being new to the hobby this was completely awesome and a trip maker. I think I still have a smile on my face from finding it. As I continued down the beach I collected many more teeth from various sharks. I couldn't believe it when I found an awesome cow shark tooth (my second trip maker) laying out in the open about 8 feet up the beach. Beside it was another good tooth as well that went in my pouch. Around 10:30 I ran into a very friendly gentleman and we chatted a bit. We talked about the weather and the cliffs, what he had found (a few hemis), and he told me a story of a fall he had witnessed a few years ago that was too close for comfort. A chunk of clay the size of a car fell and nearly crushed him, but luckily he heard some soil falling and he ran straight out into the bay right before the cliff fell. Although the clay chunk did't hit him, the water threw him up into the air when the clay hit. His friend who was a down the cliffs said he heard it and it sounded like a car crash....I didn't get this gentleman's name but I feel like I read his cliff fall story on here, so if you know who it may have been please let me know. I continued south until the tide started coming in pretty far and I thought it best to head back towards the beach since I didn't know how far it would come in or how high the water would get. I continued my search along the way back and made it to my truck around 2pm. I took a short break, ditched my sifter, texted my wife, checked email, watched a truck with two high school kids pull in to smoke a pipe (although this one wasn't filled with tobacco), and headed back out for one more quick trip down and back as the tide started to go back out. It wasn't until about 3:30pm when two more local fossil collectors came up behind me and we said hello and chatted. All in all, I only ran into 3 other collectors during the day so there was not a lot of competition (although I do like the interesting conversation). After finding a few more teeth and interesting fossils dusk approached and I headed back to my truck. After putting my gear away and changing into some dry clothes I started my trek north after a fantastic start to 2019. Below are some pictures of my finds from the day. I know what many of the teeth and other fossils are, but if you can ID something that a newbie like me probably wouldn't know then please do so as it will help me get better with this hobby. Thanks!
  22. Hello Everyone! Seems to be a good bit of interest in this topic, so I thought I’d make a little summary on what types of crocodilians you may find along the Calvert cliffs. Most of this information is gleaned from Dr. Robert Weems’ “Crocodilians of the Calvert Cliffs” in Geology and Vertebrate Paleontology of Calvert Cliffs, Maryland, USA, available freely by clicking the underlined portion. I encourage you to read that for more detail. If you have anything to add or you notice any mistakes, please let me know! Thecachampsa This genus is the only described genus along the cliffs, of which two species are described in this area. Among extant (living) creatures, it is most closely related to the false gharial. All large non-shark coprolites along the cliffs are assumed to be produced by Thecachampsa. Their vertebrae, like all reptile vertebrae, have a convex side and a concave side, making their vertebrae look like they have a ball and a socket. Their osteoderms are distinctive, with thick, blunt sections between the pits. Osteoderm associated with T. sericodon, from “Geology and Vertebrate Paleontology of Calvert Cliffs, Maryland, USA”
