  1. Calvert Cliffs Ray teeth

    Hi everyone, I would like to ask about these ray teeth from Calvert Cliffs. All I know is that some of them are Aetobatos I think. Thank you.
  2. Calvert Cliffs Shells - Modern/Fossil

    Hi everyone, I would like to ask about some brownies beach shells and corals from a while back. I think the first 3 pics including the corals and Scaphopod are modern, but I want to make sure before I discard them. The last two pics seem like fossils - is there an ID? Thanks! Modern??: Fossil??:
  3. 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”
  4. 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
  5. Growth on ecphora gardnerae germonae

    Wondering what this is on this ecphora gardnerae germonae gastropod from st marys formation. Possibly barnacle related but doesn't resemble normal barnacle base from the area.
  6. 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
  7. Found on the eastern shore of the bay.
  8. Fossil I saw???

    I saw a fossil jaw bone segment and teeth when I was in The Calvert Cliff area recently. Another hunter found a very dark colored section of jawbone about 4 or so inches long. It had a good 6-8 teeth in it (same dark color). He was claiming he had found an alligator/crocodile jaw section but it had thorn-sharp teeth. Not what I would have expected to come from a gator or crocodile. I wish now that I took a picture of it but I did not. The only other thing I can remember is that the teeth seemed various sizes, from memory. And were likely all on the side of the mouth where our pre-molars and molars would be. The front of the jaw was missing. I was just wondering what else might leave a jaw section like that. Thanks! Andy
  9. As an early Christmas present, I ordered some waders and they came a couple of days ago. It was obviously time to fossil-hunt. We made it out to brownies pretty quickly. Fortunately, there weren’t that many people there, and we rounded the point after a quick search of the area near the entrance. We promptly found a couple nice fish verts and a couple broken shark verts in the spoil piles right near the cliffs. We continued along the cliffs, searching every crevasse for the elusive meg, checking the gravel for makos and the like. Pretty far down we turned around as the tide was coming in. As we walked back along the beach, I looked down to grab a nice tiger. Lo and behold, the “tiger” was actually a symphyseal cow! It was broken with some bits missing, but it was still the rarest thing I’ve ever found! Grateful to the fossil hunting gods, FA
  10. Possible fish jaw from Calvert Cliffs

    Hello all, Today I was hunting at Brownies Beach (Maryland, Miocene) and found a rather strange piece of bone. To me it looks like the rostral portion of a jaw with false teeth but I’m honestly not sure about what it is. Maybe Wahoo material? Any help would be greatly appreciated. Anyways, I hope you all have a wonderful thanksgiving. ~Zach
  11. Fossil or mud dauber nest ?

    I recently moved some of my collection and noticed something loose on the bottom of the drawer under a barnacle. It's from a trip to the Calvert Cliffs in Maryland nine years ago. As I looked closer I noticed that they apparently came from inside two of the barnacles. Is this a fossil that I had dismissed as matrix, or is it a modern insect addition ?
  12. Good afternoon. Are there any techniques that are useful in finding larger (3/4"+) teeth on MD/VA beaches? I've been teeth diving down in SC and NC, so I get the whole "if you want big teeth, look for big rocks, shells, etc." thing. Does that concept translate in some way to searching for shark teeth from local beaches? ex. Feel for 'x' type of material/muck/clay consistency? I've gotten fairly good at finding x < 3/4" teeth (ex. High tide line material, stuff at/near the "shelf"/drop off from the beach, etc.) . My last trip out...I found my first tooth in literally the first sifter load of material. I gave a few away to passersby and still ended up with 40+. I eventually got bored with it and just started experimenting with sifting through material from other areas of the beach, with varying degrees of success. Any thoughts/recommendations? I've got a spot that I'd like to hit again. Just curious on if there's a better/more efficient method of searching. Thank you.
  13. Calvert Cliffs vertebra id

  14. Went to Brownie’s/Bayfront Park for the first time yesterday. Lots of tiny intact teeth. The smallest intact tooth was 0.23”. The largest was 0.67”. I was happy and surprised by the amount of teeth that I found. I gave a few away to curious people that happened by. One couple asked for pointers when I showed up. We talked for a few minutes, I ran one load of material through my sifter, and found a tooth right off. I handed it over to give them an idea of what to look for. I averaged 10+ teeth per hour. My best trip yet. In summary...LOTS of teeth here, a good time, pleasant & curious passers by, and lunatics in the parking lot. Get there early (I did) and with the summer heat...don’t be surprised if people are blowing their gasket in the parking lot. Witnessed one lady that was convinced someone stole her spot jump out of her minivan and proceed to curse at the “offender.” The summer heat, lol.
  15. The title says it all.... And if you can't find them here, where can you? Thanks, FA
  16. Fossil Hunt 6/22/19

    It's been a long while since I was able to fossil hunt. To go out today with a decent haul really made it rewarding. The location was on a private beach, and the weather was perfect. A bit of wind, around 78-80, warm water, and clear skies made the beach beautiful. We hunted for around two hours on the South side with minimal rewards, some really small teeth such as hemis, makos, and the like. The hunting started to pick up when we made our way over to the North Side. As soon as we arrived, a hemi around 1 1/6 washed up. I knew I was going to like this beach when a second only a little smaller washed up after a minute of hunting. We worked the beach for another hour, pulling a mako of around 1 1/4 inches (broken root) from the surf, and then another, really nice 1 inch mako in the same spot. We met a certain Steve Grossman on the beach, who invited me to the Calvert Marine Museum's sharkfest to help him set up, talk about, and look at his hundreds of megs. If any of you MD folks show up, i'll be there! The Beach
  17. It was a glorious day to fossil hunt. Warm with a soft breeze and still slightly chilly water. See, I had gotten incredibly lucky. I had gotten a connection to Dr Stephen Godfrey and he invited me to hunt today at a classified location (sorry I am not allowed to spill the beans). Our friend Mr Eric came along as well as MomAnonymous. As soon as we had gotten there, interesting things began to appear. Dr Godfrey began to point out things i'd never had understood without being told. At the bottom of the cliff face, Dr Godfrey pointed to a strange indentation and then told us a story about he and other paleontologists finding completely intact fish skulls at the cliffs, which are nigh on impossible to find. Then he told us that the skulls were a type of tilefish, which as some may know burrow through mud. These tilefish buried themselves in these burrows and they became a kind of tomb, which is why they stayed intact and weren't destroyed. At this time, the Hobbit (movie) had just came out and when Dr Godfrey was given the ok to name the species, he went from something from the Hobbit. Dwarves tunneled, and their mountain was named the Lonely Mountain, and Erebor in the elvish language, and the species became Eraborensis.

    Baleen Whale Phalanx Bone Parvorder Mysticeti Miocene Virginia
  19. Ecphora Snail

    From the album Virginia Miocene

    Ecphora sp. Miocene Choptank Formation Virginia
  20. Unknown for me from Calvert Maryland

    Can someone possibly clue me in on what this tiny bone is? It looks like it has a tooth attached or something of the likes...thanks in advance
  21. Mini Miocene Marine Mammal

    I found this a few days ago along the Virginia side of the Potomac River along a miocene cliff. It's mostly if not all Choptank formation. Any ideas about a genus? Grid is in inches. Looks like maybe mature dolphin tailbone, but it's so small???
  22. Mystery Scapula

    I found this scapula this weekend along the Potomac River in Virginia. It's a vertebrate. That's all I know for sure. Most of the cliff next to the beach where I found it is miocene marine, but the very top is pleistocene terrestrial. The grid is in inches.
  23. Exploring the Virginia Miocene

    Spent a cold, soggy day on a private trip along the Potomac yesterday. The mud was so saturated that we were sinking up to our knees where the sand met the mud at the base of the cliffs. It was totally worth it! Came home with treasures untold until I finish unpacking. I know there are some really nice whale vertebrae in there, including the one below. There are also a couple nice Ephora snails and what looks like maybe an echinoid -- really rare for the area if it is! My daughter found a couple snaggletooth shark teeth that are actually iridescent and blew me away! Here's a video report of the trip: Sorry I can't say specifically where this is. They are having problems with uninvited guests already.
  24. Megalodon or Chubutensis?

    Hello everyone, If you saw my most recent trip report, you know that I just found my first meg tooth! However, I'm not entirely sure whether the tooth is from Carcharocles megalodon or Carcharocles chubutensis. The tooth was found at Bayfront Park/Brownies Beach, which is the northernmost part of the Calvert Cliffs. The sediments exposed in the cliffs here are from the Calvert Formation, roughly 18-22 million years old. This would be right around the time when the great Megalodon first emerged. I remember reading that the majority of megateeth found at Brownies are chubs, but that megs have also been found there. What I'd like to know is which one my tooth is: Meg or Chub? It looks to me like if the tooth were complete, it would have the defining residual cusps of chubutensis, but unfortunately the blade is broken on both sides right by the root. The bourlette is missing, but that is a characteristic of every shark in the mega lineage so that doesn't really matter. The tooth is approximately 1 3/4 inches, and not quite as thick as I would've expected. As you can see on my trip report and Hop 5 post, my current ID for this tooth is C. chubutensis, but that is subject to change should someone with better knowledge on megatooth identification give their opinion. One last possibility is that it may be a transitional meg, meaning the shark was a blurred line between megalodon and chubutensis. Any input is appreciated. Thanks!
