    Is this a Mako tooth?

    I found this tooth at Calvert Cliffs, Md. The root looks to thick to be a Bull shark. A small Mako is my my best guess. Does anyone know?
  2. Found in a Cavert cliff formation outcrop in Washington DC. It appears to be a fish hyporal fan (telos) whatever that is.
  3. Found an interesting ray tooth mixed in with about 300 more i'd found on a recent trip down to MD. Dimensionally, tooth is about 1" long and matches other teeth from the area. That being said, the color and porous texture do give me pause about the tooth not being mineralized
  4. Hi TFF, I found a small skull walking the beach at Flag Ponds this morning. It measures about 3" long and 2" wide, thinking some sort of small mammal based on the font teeth. The skull is quite heavy and fits the same color/weight/texture of the numerous bone fragments found in the area. Images edited to show further detail, would appreciate help with an ID In situ: Close-ups

    Tilly bone or coprolite?

    Hi all, I found this on Matoaka Beach, Calvert Cliffs, Mayrand. Sorry I don't have a ruler with the image - as you can see it is quite small - about 15mm Thanks, Tom

    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!

    Flag Ponds Finds

    Hi all! Just recently got into fossil hunting (besides coming the beach for teeth haha), and since moving to Maryland I’ve had access to the Calvert Cliffs area, which is so exciting! On my most recent trip I found all of the pictured pieces in the surf, around low tide, and in sight of some of the cliffs near Flag Ponds. I think the first one is a large piece of whale bone, with a fun hole in it! But the rest are really eluding me. I took some less contrast-heavy pics of the very black bone fragment as well. Any idea what they could be? Thanks so much! ☺️

    Need confirmation on what this is

    Was at flag ponds today looking for fossils in the Calvert formation. This looks like a cetacean rib fragment? Dolphin/porpoise? Thanks all.
  9. Hello , I found this tooth at Calvert cliffs park in Maryland a week ago . It was different from the rest of the teeth and I’m having a hard time Identifying it , maybe y’all can help me .
  10. Hello , I found these two teeth in Calvert cliffs , MD . I just wanted to know if they are crocodile teeth , porpoise teeth , or if they even are teeth ? . I would appreciate any input thank you .

  13. Hi all! Went on another expedition to flag ponds in Calvert MD the other day, had probably one of my best hunts so far in the formation. in total I found 112 teeth, 51 shark, 59 ray, 2 bony fish. I yelled in excitement when I found this one in the shell bed, blending into the grays. There's only two things this tooth could belong to and one of them is a shark I have been hunting for years. I am leaning towards Meg in my ID, as the break line seems to go across the middle where the chevron would be, in addition to the profile of the tooth is girthier than the hastalis I have found. Just to make sure i am not falling for seeing what I want to see. I have shown it here. fragment measures about 1 inch on the diagonal. here is a Burrfish puffer fossil i found in the sifter. for the bones I have a couple more that I am unsure of the ID. this one might be a turtle shell or a reptile bone of some sort? it cant be a cookie I dont think because the ridges are not as pronounced. this bone is odd, because it look slike it has a flat surface on both sides. which makes me wonder what part of the cetacean this migh tbelong to. also, there is a scratch on the sidethat might be a possible predation mark? this one is a carcharhinus tooth I found that seems to have a pathology. the tip is bent outward and up. possibly some other species? this looks to me to be the process of a fish vertebra. I am not sure what this is, but my gut tells me its a fish fossil, these bones both have a similar look/ profile which tells me its a common type of fragment. any ideas? bird bone? it doesnt look to be bog iron, and its shape rules out fish or mammal fish vertebra? anyway, your expertise as always is appreciated! let me know if theres any details about these I missed.

    Calvert Cliffs Finds

    Hello all, since I finally joined this awesome community, I decided to post these two I found many years ago at Calvert Cliffs, MD. The beaches yield marine fossils of Miocene era, shark teeth, shells, porpoise, whale, etc. I’ve always assumed the bone was something really recent but hung onto it just in case. Always assumed the tooth was some sort of crocodilian but I don’t know if that makes sense.

    Fossil id (Calvert MD)

    Hi! First, thank you to everyone who responded to my older post asking for fossil hunting tips- I used as many as I could and I found some great stuff! Here's what I found and can't ID myself from my latest trip to Flagponds (Calvert MD). I was thinking 11 might be snaggletooth shark, and 19 and 20 looked like they might be from some kind of white shark though I'm not entirely sure? In addition to those I'm especially interested in identifying 1, 3, 4, 5, 8-9, and 13 but haven't been able to so far. I'd appreciate any help identifying these and the other teeth I have pictured! 36-48 are possible bones and bone fragments which I thought might have some potential for ID. If different angles or views are needed for any of these I'm happy to take more pics! Lighting in my house isn't ideal so these are the best I could do without taking pics of each bone/tooth individually. Oh they posted all out of order, sorry about that!

    Shark teeth!

    Hi! I just wanted to show off my best fossil hunting finds so far, I hope that's ok! I've identified them from left to right as extinct tiger-like shark tooth, snaggletooth shark tooth, tiger shark tooth, sevengill cow shark tooth, stingray barb, and pufferfish mouth plate I also included a tooth from a previous trip (second from the left) just to show why I'm so proud of these

    Calvert Beachcombing Tips?

    Hi guys! So I'm planning to go back to one of the Calvert County beaches to try my luck again- I haven't had any success with finding teeth bigger than about a quarter inch and I'm hoping to find something a little bigger next time. My current technique is to dig up sand from the water and sift through it super carefully- should I switch it up and try something different to find big teeth? If so, does anyone have any recommendations for how to find them? And, final question, which beaches are good for finding larger specimens? I know Purse and Matoaka are good for quantity but I don't know which are best for finding big fossils. I'm still very new to tooth hunting so any help would be appreciated!

    Calvert County Fossils

    Hi everyone! I went to Flagponds in Calvert County MD a few weeks ago and came back with my biggest *actual* fossil haul so far (I posted here my first time with about 50 barnacle pieces)! I know there are a few ray plate fragments in here, and I've included what I think are bone pieces although I'm not entirely sure. Anyway, I'm having a lot of trouble identifying my shark's teeth, so any help with this would be greatly appreciated! I'll post numbered photos of my finds with this. If anyone needs a zoomed in, clearer or different angle pic I'm happy to provide more. (Advance apologies for the broken down photos, these teeth are really tiny so I had to take multiple pics to make them visible)
  19. I’ve never been collecting in the Chesapeake Bay before and am gonna visit the area soon during low tide. Which locality (beach, site) produces a good quantity and diversity of fossils. I’m not fixated on finding big megalodon teeth. I’d love to find a nice *Ecophora* and maybe some dolphin teeth. Species diversity would be nice.

    Fossil ID Matoaka trip 2

    Hi Again! for Easter this year I decided to go to the Calvert cliffs for some Easter egg fossil hunting. it was a lovely day out got to talk with some nice folks. I wanted to share some of my finds and my IDs of them to check if I got them right before I put labels on them in my collection. 1) Stingray teeth, most likely eagle ray, although the grayish one looks to me like a duck billed ray. 2) Mako Shark Isurus hastalis upper 3) Hemipristis Serra upper 4) Extinct tiger shark Physogaleus contortus 5) Extinct tiger shark Galeocerdo (I think the one below is a lower) 6) Crab claws ( is there any resources on specific crabs, some of these don't look like they belong to the same species) 7) Turritella plebia 8) Scallop shell (Chesapectean?) 9) Fish jawbone fragment (looks like sockets on the top) 10) Bone shard (there seems to be two divets below)
