    Purse State Park 4-5-21

    I was able to get out to Purse State Park this morning for a Maryland Paleocene (Aquia Formation) hunt. I usually prefer the nearby Douglas Point when I hit the Potomac River but I decided to give Purse a try as I haven't been to that stretch in a while. I was the second car in the lot but first on the beach, which is always the best way to start the fossil day. My first good find--a croc tooth, though the enamel is very worn: Followed by an Otodus -- also quite worn but a decent size for the site (approx. 1.25"): It really turned into a gorgeous day! Can you spot the bald eagle? My find of the day: I've been finding ratfish material on most trips lately, but just small fragments. This is my first mostly complete tooth plate. Something interesting in the water... Multiple Otoduses always makes for a very good day. Like the other one (and all of my shark teeth today), this one's river worn. A good sized croc tooth: I did a fair amount of walking and exploring along the shoreline and didn't see too many people along the way, but the entrance to the beach was quite packed by the time I headed for the exit. Thanks for reading!
  2. I've wanted to put together an artificial tooth set of Striatolamia striata from the Aquia Formation in Maryland for a while given the abundance of that species in the formation. Until recently, though, I was missing a lot of the less commonly collected tooth positions--extreme posteriors, intermediates, and first lower anteriors. After searching through several gallons of Potomac River gravels over the last couple of months, I finally filled in the gaps. I put together the tooth set below a few days ago and just finished mounting them in a riker box I received in the mail yesterday. I used the Striatolamia macrota artificial tooth set on elasmo.com as my guide. I'm sure some of the teeth in my reconstruction are out of place, including some of the upper or lower teeth possibly being from the opposite jaw instead. I couldn't properly size match the intermediates and first lower anteriors, but can always swap in replacements if I find them. One of the extreme posteriors is also reversed in the display (labial side showing rather than lingual like the rest) as I'm still missing a tooth from that position. Overall, I'm quite pleased with the result. This is my first artificial tooth set, and it was a fun project that taught me a lot about tooth positions! Here's the full tooth set -- the largest teeth in the display are just over an inch long: Left and right sides: Quadrants: The final riker display:
  3. My son asked to be taken to find shark teeth for his birthday. We are planning a trip to Calvert Cliffs in May. Does anyone have any suggestions to make this kids bday a success?
  4. I have an upcoming trip around the Point A Dam in Alabama. Is this site still in good shape with the recent weather that's been cranking through the south? If the dam is out, are there any other good sites still in existence in 1-3 hours drive south of Andalusia? I've read about a lot of northern panhandle sites in Florida but wondered if they're still in existence or have been wrecked with Hurricane Michael. Also, I work mostly dry sites in the Paleozoic of West Virginia. Is this a site where muck boots are warranted? If so, are mid calf height enough or better to have waders that go over the knee? I'm wondering the same thing at some of the Northern Panhandle of Florida sites which apparently are mostly stream and creek beds? One friend mentioned old shoes and wool knee highs being enough. Would love to hear opinions of others.
  5. Hello everyone, I'm new to this so I don't have much experience IDing teeth. I found a few shark teeth at Calvert Cliffs in MD and I was easily able to identify most of them by comparing them to some photo guides online, but this one didn't seem to quite match up to any standard examples I could find. It's just over a centimeter, very symmetrical except where a top corner is broken off, and has pretty clear little serrations. Hopefully an easy one for someone who knows more than I do! Thanks!

    Potentially interesting Calvert Frm teeth

    As I’ve mentioned in other posts, we got quite a bit of matrix from @sharkdoctor recently. Much of what he sent was from the Calvert Formation. Most of what we found was fairly easy to identify as Aaron provided the guide for the Calvert. When I got the very end of the bag from lag site 210, I found a couple of teeth that I could not match to those in the guide. They appear to me to be Catshark but of a different morphology than those in the guide and quite a bit different from those I had found. They are a bit larger than the other Catsharks I found and overall seem to look more like Pachyscyllium teeth. Unfortunately none are complete but there was one that is I think is complete enough to perhaps ID. I am going to send Aaron these pictures and they may get forwarded to the CMM but in the meantime I wanted to see if I am way off base in my thinking. Any and all opinions are welcome. First tooth is the most complete and largest at 3mm .

    Unusual shark teeth

    I went out to Douglas Point (Paleocene, Aquia Formation) in Maryland yesterday and found a couple of unusual shark teeth. The tooth on the left is about 1.5 cm long and I'm pretty sure is a pathological Striatolamia striata. The tooth on the right looks a bit like an Otodus obliquus or Cretalamna appendiculata to me. Since it's only 1 cm long, Cretalamna might be the better guess. I'd appreciate any thoughts on the IDs. Thanks! Here are some more views of the sand tiger on the left. The root is both relatively large and very flat. It appears to be chipped in a couple of spots as marked in the top middle photo below. There is a small cusplet on one side but not on the other. This is perhaps the most peculiar-looking tooth I've found. And here are more views of the "Otodus/Cretalamna". The blade is a bit wavy and might perhaps be pathological too.

    Cookie Cutter Creek

    Many years ago, Cookie Cutter Creek was the first location I had the opportunity to hunt Florida fossils at thanks to @jcbshark. That day, while he screened a 5 gallon bucket of matrix containing the Cookie Cutter teeth, I looked for megs. What an ameteur I was, not appreciating the special teeth Jeff had in his bucket of gravel. As time has advanced, I became interested in the micro fossils from this creek and decided on a trip to the area back in February to try on my own, sifting some matrix to take back with me. Hopefully the elusive Cookie Cutter (Isistius) tooth would be amongst all those grains of sand. So I cut a few different sizes of screen and packed them in my suitcase for the trip. Nothing fancy. Then proceeded to the creek one morning, all excited to give this a try. Could I remember how to get to the stream? Two hours later, the answer to the question was NO! So that night, I scrutinized the area on Google Earth and tried again in the morning. This time I was successful! Armed with my screens and a baggie, I attacked the creek. It didn't take long to fill it, so instead of returning to my son's apartment, I forced myself to look for larger shark teeth for awhile (another success). But it wasn't until yesterday that I was able to ascertain whether my hunt for the elusive Isistius was successful. Here are some of the SMALL teeth I extracted from the bag of gravel. Here is a picture showing that I was successful in my Quest to find a Cookie Cutter tooth on my own!!! These sharks are called "cookie cutter" for a reason. They attach to their prey and remove a circular piece of tissue, mimicking a cookie!!!

    Teeth from Douglas

    It was very cold this morning, but I still managed to do some sifting for small teeth. I was disappointed that I didn’t get any “hound shark” teeth, but I still got some good items.

    Unknown shark teeth

    These show up fairly often in the basal pecan gap which has been the focus of my searches recently, nearly all the shark teeth here have the root dissolved so that diagnostic piece is missing but this looks unique enough I'm sure someone has seen something similar, they seem to have a sort of nacre look to the white part so maybe not sharks tooth. This is the largest I have. Microscope pictures with a phone are shaky at best. end on and the back And a smaller more typical example any help appreciated

    Fun with Calvert Formation micros

    We were very fortunate to get quite a bit of Calvert Formation micro matrix and some great teeth from @sharkdoctor. This is my first exploration of this formation and I am loving it. Lots of Carcharhiniformes material and it will take me a little time to ID some of Carcharhinus teeth but that is a good learning experience. I need the practice. The very fine matrix has been my favorite. I’ve found a few Scyliorhinus teeth, a few Squalus teeth and a few Mustelus teeth. Raja teeth are way more common than in STH. I’ve searched a lot of STH matrix and found 2 Skate teeth. It took me 10 minutes to find two in this mix. I have a lot more searching to do but I am really enjoying this.

    Southeastern United States Sharks

    I received a lot of teeth from the Southeastern United States today. I couldn't identify three. While many of these came from Bone Valley, I can't say for certain that these three are from that locality. The only provenance I have to go with is the Southeastern United States. Here are front and back shots for each of the three teeth. The first two are 1/4", while the last one is 1/8". Each has cusps. I would appreciate any help with this. Thank you, Bellamy

    Pecan gap shark teeth

    A couple hours searching a new to me exposure of pecan gap chalk turned up some pretty nice stuff. First a couple of shark teeth, I don't know the identification. Actually this one might be a fish tooth: I love the color on this one. Also got a lot of fish scales and a small fish vertebra. Vertebra: Scales: A good sized ammonite. And a UFO. An unidentified fossilized object, if you know what this let me know.

    Russian Sand Tigers

    I purchased some shark teeth recently, all or most of which appear to be sand tigers, from Russia and am hoping some folks on here might be able to help me identify them. The information from the seller, who is in Russia but didn't collect these himself, is that these are Cretaceous teeth found in chalk deposits on the banks of the Don River, near Kalach-on-Don, Volgograd region, Russia. He doesn't have any more info or know the exact geologic layer. I haven't been able to find much information from searching online, but using the app Rockd, it does appear that the geology in the area around Kalach-on-Don is Late Cretaceous (see composite screenshots from the app below). Many of the teeth themselves also have remnant white chalky matrix on them and some have what appear to be calcite crystals on them. If anyone here knows more about the geology/stratigraphy of the area that you could share with me, that would be great! Below are photos of the teeth. While the info above checks out, I have some suspicion that these teeth might be younger than Cretaceous in age. I may well be wrong about that, though, and would be happy to know either way if you think these look like Cretaceous teeth or if you think they're from a more recent time period. These are nice looking teeth that were reasonably priced, and I don't mind if they're younger; I'm just interested in trying to identify them. I've tried to organize the teeth in the photos below into groups with similar characteristics. Please let me know if any additional photos would be helpful, and thanks in advance for any help you can provide! Group 1: These all have lingual striations, except for the tooth on the far right, though that one's more worn and may have had them originally. The tooth fourth from the left/third from the right has very different coloration than all of the other teeth I acquired and reminds me of the coloration of teeth I've seen from Kazakhstan (perhaps it was accidentally mixed in?). You can't necessarily tell from the photos, but these all have very small lateral cusplets/nubs, one on each side. Here are additional views on the leftmost tooth above, which is generally representative of the others. One reason I question whether these are Cretaceous in age is the striations on these remind me more of Striatolamia sp. teeth I've seen from the Paleocene and Eocene than Scapanorhynchus sp. teeth from the Cretaceous, which in my albeit limited experience have deeper/more prominent striations. The striations on these teeth also do not appear to extend onto the roots. Group 2: These teeth are also lightly striated on the lingual side, which you can see more clearly in the second set of photos below detailing the leftmost tooth. These all have one lateral cusplet on each side of the cusp (more rounded on the two teeth on the right). My guess is these are the same species as the ones above, just different tooth positions. The tooth on the left in particular does remind of Scapanorhynchus sp. Here are more detailed views of the tooth on the left: Group 3: The teeth below all lack striations; the preservation is quite good, so I don't think they ever had them. These teeth have fairly large lingual root protuberances. The first three teeth each have one sharp, but small lateral cusplet on each side. The two teeth on the right both have two lateral cusplets on each side. Here are some more detailed photos of the leftmost tooth: And here are some closer photos of the two teeth on the right, which have two lateral cusplets on each side: Group 4: The two teeth below also lack striations and have one pointy cusplet on each side of their cusps (one of the cusplets is broken on the left tooth). I've separated these two out from the teeth above as the lingual protuberances aren't as large/prominent. Group 5: These are somewhat smaller teeth that may be from the same species as teeth above. All three lack striations. The one in the middle has two cusplets on each side while the other two each have only one. Group 6: These two teeth have more u-shaped roots and narrower cusps than the ones above. They lack striations and have one cusplet on each side of the cusp (though some are broken). Group 7: This tooth has more triangular cusplets than the ones above and a more angular root. It lacks striations. Group 8: The final tooth is a bit worn, but reminds me of the Cretaceous thresher, Paranomotodon sp.

    Help with Some Matoaka Beach Finds

    I was out at Matoaka Beach (Calvert Cliffs, Choptank Formation) a couple days ago and found a small but great quality megalodon tooth, a great-looking crocodile tooth, and then what looks to me to be a small aquatic mammal tooth. I have a couple questions about them. 1. Can anyone tell if the megalodon tooth is from a juvenile animal or just one of the posterior teeth of an adult animal? 2. What is the typical genus/species of crocodiles in this formation that you typically find teeth for? 3. Any ideas on the smaller find? I think it could be a tooth belonging to an aquatic mammal, but pretty weathered down without much enamel. Any other thoughts?
  18. Went out to Matoaka Beach this past wednesday for a sunny but pretty chilly day of fossil hunting. While I do enjoy chatting with other fossil hunters, having the beach pretty much to myself for the day was really nice. After a couple of hours pretty close to low tide, I spotted a sizable crocodile tooth rolling in the surf. I was already stoked about that, but the best was yet to come. Maybe about 30 minutes later, I was sifting around with my shark tooth sifter, and my breath caught, spotting this small but complete and terrific looking megalodon tooth. My first one! As always (at least for me), I found both pretty close to the bigger cliff falls further down the beach, for those of you familiar with the location. While it was freezing, it was my best trip to Matoaka to date, finding two uncommon and great quality fossil teeth. I also found a small but great quality hemi and what I think might be an aquatic mammal tooth (I'll post pictures separately for some opinions in the ID forum), as well as a few Ecphora shells. Matoaka can sometimes be hit or miss as those who frequent the location know all too well. I usually find at least something small there, but these finds show you can really find some great stuff if you look carefully enough.

  21. First of all, my utmost sympathy for all of you in the midwest who are snowed in and freezing off your extremities. The worldly weather patterns are wreaking havoc on us lately. Over here in southern Germany the sun is shining again, the temperatures have been rising for the last few days and the last of the snow has turned into vapor in my parts. So it was warm enough to mount my bike again today and take a trip to my favorite shark tooth site. Here's what I came up with. A good selection of various species and a nice Galeocerdo aduncus posterior.

    Mesaverde Formation Round 2

    I have been a little bored lately and missing micro matrix searches. It’s been awhile since I’ve gotten to enjoy hunting for tiny shark teeth. I got some more matrix from the Rollins Member of the Mesaverde Formation. My first time through that matrix produced one of my favorite finds, a 1mm Scyliorhinus tooth. This formation doesn’t provide much in the way of complete teeth but it is a fauna that was really quite diverse. The first search was with less matrix but I found enough to want to do it again. This time I have more matrix and in varying states. Some is broken down, some is in small matrix bits and we have a small piece of untouched matrix. It’s a good chance to practice breaking matrix down and learning a broader approach to collecting. The first search of the broken down matrix and first look at the small bits has yielded few complete teeth but a much wider diversity which makes it fascinating. The first Squalicorax, Ptychodus, Lissodus, and Rhinobatos. It also produced an Orectolobiformes that doesn’t appear to be Chiloscyllium. It looks much more similar to Restesia. I am really looking forward to searching more as the breakdown goes forward. I am going to take closer pictures tomorrow but the first time finds are among the teeth in this picture.

    Shark Teeth St Augustine Florida

    Ok I was lucky to find these shark teeth in St Augustine last week. But help with identification please. My guesses are Mako top left followed by Sand Tiger and lastly a small Great White? Or could that be an extinct Mako? Thanks for your help.
  24. I have been fishing more than beach combing and the collecting has been poor (or maybe I'm going blind!) Lots more people this year hunting stuff with metal detecters, screens and better eyes. This would have been great for one trip, but accumulated over 8(?) trips. Hopefully with better winter storms more will turn up, and the cold will keep most people away.
