    I posted photos of Mrs.SA2's 1st meg of the new year on @RCW3D's Potomac River post from 1/20/18. Today, @MarcoSr, Mrs.SA2 and I wanted to try some hunting in the sun today instead of the feet freezing water and ice we had yesterday, so we went to a place we knew would have all day sun. When we put the boat in there wasn't any ice on our side of the river and only a little bit on the beach. Weather forecast was mid-60s and mostly sunny, perfect for late January in VA/MD. We motored to our planned starting point and started walking. Unfortunately, we immediately found lots (and I do mean A LOT) of footprints all over the beach. We kept on going and found a few teeth to start. Being out with MarcoSr is always a great time because I learn so much and have great conversations about stratigraphy. Here is my 1st tooth of the day, it's right at 1 inch, but ensured we didnt get skunked on the day. The rest of the day consisted of a few small teeth found plus a lot more footprints along the beach. At least it was sunny and warm. Didn't take an hour for us all to come out of a couple of layers of clothing. As we got a couple of hours past low tide, Mrs.SA2 did it again, and found her 2nd megalodon in as many days. She brushed a few leaves away from the gravel/cobble and there it was, in all its glory. I'm surprised she let me get a couple of photos before she grabbed it. Once we got a couple hours after low tide, the wind changed directions and picked up in intensity. Neither of these things were forecast and it started pushing the ice from the other side of the river, towards us. Didn't take long and there was large ice flow pinching us off from getting back to the ramp and I had to do some serious navigating to get around / through it. @RCW3D would have been proud as we once again plowed ice, and this ice was much thicker than yesterday. Some of it was 6-8 inches thick and obviously, we avoided that and chose our way through the thinner, slushy stuff. Here is a photo of the ice flow on our side of the river causing us to motor out to the middle to try and get around it. Good thing MarcoSr and Mrs.SA2 trust my boating skills. Here is the boat ramp after we pulled the boat out. Remember, there was NO ice there or anywhere near us when we launched. I busted up and pushed all the ice around the ramp with the boat so we could pull out. The dark spot in the middle of the right side of the photo is a full size duck blind that got ripped off its posts and carried away by the ice. Here is a photo of "our" side of the river after the ice flow moved in on us. The ramp is at the white building on the right side. (Don't worry folks, there are several other boat ramps within a 20 minute boat ride that we could tie up to and go get the truck and trailer.) Cheers, SA2 and Mrs.SA2
  2. Mystery Fragment from Purse State Park

    Hi all, This little fragment was one of my many finds at my first trip to Purse State Park. I've posted a trip report; go check it out if you haven't already. Although I found hundreds of fossils, I had very little trouble with identification as the formations at Purse only yield a handful of fossil species. But this one strange fragment has got me stumped. It's about 3/4 of an inch and pretty thin. One side is very bumpy with a small, smooth protrusion in the middle. The other side is very smooth with no bumps but some very tiny holes. It looks somewhat similar to a few of the crocodile and turtle fossils found along the Maryland Potomac coast that I've seen online. My best guess is that it is a scute of some kind due to the protrusion on the bumpy side, or perhaps a skull fragment. Again, I'm really not sure with this one. Any help would be much appreciated. It's always exciting to find something a little different! Thanks. Hoppe hunting!
  3. Purse State Park 12/22/17

    There are so many testaments to Purse State Park being a fantastic fossil collecting site online, and because of this I thought I’d go there myself and test my luck. I kept on hearing about quantity, and how Purse yields more fossil sharks teeth per trip than just about any other local site. I was blown away when reading that people come home from a single trip with hundreds of teeth, and of decent size and quality too! And so a few days before Christmas, I packed up my gear and made my way across the border and down the Potomac to Purse State Park.The drive there was just fine, and the park is very secluded, unlike some other common sites. Perhaps its isolation contributes to its lack of a crowd in comparison to the Calvert Cliffs. The park is quite difficult to find as it is not clearly marked; I actually drove past it at first and had to turn around! The parking lot is on the left side of the road, and you have to cross the road to get to the trail. The hike is a little under a mile, which can be a pain if you have a lot of gear. It’s also practically in the middle of nowhere, so be cautious. Eventually, you’ll find yourself on a very nice little beach along the Potomac River. The cliffs run along the majority of the beach, and you can even see the exposed shells and cliff mix in the lower layers of some parts. In terms of area, this site is astonishing! There is at the very least a mile of beach, not to mention the fact that you can venture far past that thanks to the high tide line law in Maryland. You really could just keep walking, and I did just that, but even then I couldn’t cover all of the area even in the eight or nine hours that I hunted. If your looking for a place to hunt where there’s more beach than you know what to do with, head down to Purse.The fossils found here are from the Paleocene Era, much older than the Miocene exposures at the Calvert Cliffs. They are approximately 60 million years old, which is nearly dinosaur aged! One area where Purse does lack, however, is variety. Although you may find loads of teeth, they will all likely belong to only a handful of species unlike the Calvert Cliffs that yield hundreds of different species. This being said, the species found at Purse State Park are fascinating. The majority of teeth found will be those of extinct Sand Tiger Sharks, although you are able to find ray plates and mackerel shark teeth as well. Maybe you'll even be lucky enough to uncover a dreaded Otodus!I got to the park just a few minutes after sunrise, making for a beautiful sight. Once I began searching, I quickly learned that my shovel and sifter were rendered near useless, as I was finding teeth left and right by simply using my eyes. Surface hunting allowed me to cover a lot more distance in a lot shorter time, and I also began developing an eye for sharks teeth; there were a few time I spotted a nice tooth with only the root showing in the gravel or sand! The air temperature was not too bad, but the water was absolutely frigid and I had to take multiple breaks to avoid losing feeling in my hands completely. I tried to cover as much beach as possible without going too fast and missing teeth, and I was quite successful in doing so. To the left of the entrance, I walked for at least a mile finding tons of teeth, and I eventually stumbled upon a large and complete Turritella mold! I had found tiny fragments towards the entrance, but I was ecstatic with this find. But then, I found another. And another. When I looked up I realized I was standing right by a multitude of cliff falls that were full of these Gastropod fossils! There were hundreds of them, both in the rocks and freshly washed into the surf beneath them. I picked up the prettiest ones I could find, even carefully prying one out of the matrix. As sunset approached, I had found hundreds of fossils including teeth, plates, molds, and possible bones (turned out to be pseudofossils). But aside from some good sized sand tigers, I didn’t have anything too spectacular. But in the last hour of searching, I turned over an object that was mostly buried in the sand. To my delight, it was a nearly complete Otodus tooth! My first relatively large tooth, and a great way to end a great day of hunting! Otodus obliquus was a giant shark, nearly 35 feet in length, that was likely the ancestor to megatooth sharks like Megalodon. And since Megalodon was not alive during the Paleocene, I’d argue that finding a tooth from its great great Grandpa is just as cool! And with that, I found another handful or two of teeth on the way back to my bag and began to leave as the sun set over the horizon. On the way out, I got to share my finds with a family who was walking their dog along the beach. They were the only other people I saw in the park all day long; other than that I had the site to myself. I said a big thank you to Purse State Park, and hit the road.In total, I found an incredible 619 sharks teeth, along with over 50 other fossils! Like I said, this site delivers when it comes to quantity. Some of my favorite finds are the large Otodus in the middle, the Turritella, and the long and complete Sand Tigers. I was only able to display so many teeth before my space was overcrowded, and I had to put the rest in a pile. I am beyond happy with the results from this trip; it was by far my most productive trip yet. I hope you all enjoy seeing my finds and hearing my report, and I hope you’ll pay a visit to Purse! As always, Hoppe Hunting!
  4. Possible Human Modified Bone?

    Hello again! Found this bone fragment at Flag Pond yesterday and it appears that it may have been modified. Could it possibly been a Native American tool? Notice the point, symmetrical indentations at the base/stem and the hole at the base. Thank you for your help!
  5. Hello... I found this small tooth yesterday at Flag Pond in Calvert County MD. It is embedded in a small jaw fragment (the small tooth is circled in red). The jaw fragment is solid, not appearing hollow like a fish jaw. Any thoughts on what it could be? Thank you for your help!!
  6. Hey guys! I took my second trip to Brownies beach! I found 180 shark teeth, a porpoise tooth, an almost complete ecphora, and some type of land mammal tooth. Also, if anyone can help me identify the land mammal tooth while you’re here that would be awesome. Here are my favorite finds.
  7. Brownie's Beach 11/25/17

    After some careful thought and many references to suggestions from TFF members, I decided that my first fossil site would be Bayfront Park aka Brownie’s Beach in Chesapeake Beach, Maryland. I packed up my newly bought expedition gear, sifter and all, and headed out. It was a little over an hour’s drive, which is not bad at all if you ask me. It was the day after Black Friday, so I had thought maybe everyone would just want to stay at home. But given it was a weekend, and families were in town for Thanksgiving and looking for something fun to do, my timing ended up not being ideal. When I showed up, the place was pretty busy, but I started collecting right away. There were quite a few other collectors, and in talking to them I learned that small teeth were a common find here, and in very large quantities. I actually didn’t find anything for a while, due to a number of things. The conditions were mediocre, considering how crowded it was and how the beach was riddled with those pesky autumn leaves that make combing the tide lines a real pain. Also, I was able to be at the park during low tide, but I would hardly call it that, as the water barely retreated at all. Must’ve just been the wind direction. But regardless of the imperfect circumstances, I was able to get a nice handful of small fossilized shark chompers and ray plates. My largest tooth, although still small, was actually the first one I found! A decent Physogaleus contortus I believe. Unlike the other teeth, I didn’t even have to sift for that one. Just found it chilling among some pebbles on the sand bank near the entrance of the park. The second I saw it I went “Ooh! That’s a tiger” and gladly picked up my first ever fossil. It will always hold a special place in my heart, even if it’s not the best find. Aside from my tiger, I found a bunch of Lemons, some real nice baby Sand Tigers, and I think some small Dusky. Again, I'm new so please correct my identifications. I also got my hands on some ray plates, and (although I had no idea what it was when I picked it up) a dolphin/porpoise tooth! I’m not quite sure what the black object next to it is, but I believe it to be something like a snail shell. If anyone has any clue what it is, let me know! Overall, I’d say I had a good first fossil hunting trip at a really beautiful site and I got to meet some nice people who share my passion. I got some cool finds and I can’t wait to hunt some more. I won’t let the small teeth scare me away from Brownie’s; I definitely plan on returning in better conditions to get some bigger, better finds. I actually plan on going in the winter, not too long from now! Hope you enjoy the trip report. Hoppe fossil hunting!
  8. I brought home a limb of matrix that had fallen out of the cliff the other week. It dried out and chunks started falling off, revealing a teardrop-shaped shell and a pair of scallops. I carved through it, gluing the heck out of the tear-drop shaped shell the keep it from crumbling, and working all the way around the exposed shells so as not to break them. I found maybe a dozen 1/2-inch or smaller molds and lots of paper-thin bits of broken shell. When I finally dug out the exposed shells, I realized what the rest was-- broken bits of Isognomon maxillata, baby ones, a whole bed of them! I talked to my friend at the Delaware Museum of Natural History, who was also intrigued. He's going to take the remaining lump and examine it carefully under the dissecting scope to see what else might be in there. Lots of things predated the oysters, so could be some interesting micros in there!
  9. Again, new member

    I’m not a person to try and show off or one up a person. I only want to learn and better myself without stepping on toes and enjoy what I do. I thank everyone for having positive comments and helping me on my previous posts. Here’s some of the finds that I’m pretty proud of and looking for opinions and what people think.
  10. Greetings! We found this fossilized egg on the banks of the clay cliffs in Maryland. We frequently find fossilized shark teeth, stingray jaws, whale vertebrae, and megalodon teeth on the same banks. It was a round/oval shape with a crack in the top and we proceeded to break it open (not the best idea now!). You can clearly see the yolk and egg layers. We would love any help identifying it! Thank you!
  11. Fossil Snail Sea Shell Turritella.jpg

    From the album MY FOSSIL Collection - Dpaul7

    Fossil Snail Sea Shell Turritella plebia St. Mary's formation, in the Calvert Cliffs, of Calvert County, Maryland Miocene Period, 23 million years ago Turritella is a genus of medium-sized sea snails with an operculum, marine gastropod mollusks in the family Turritellidae. They have tightly coiled shells, whose overall shape is basically that of an elongated cone. The name Turritella comes from the Latin word turritus meaning "turreted" or "towered" and the diminutive suffix -ella. The Gastropoda or gastropods, more commonly known as snails and slugs, are a large taxonomic class within the phylum Mollusca. The class Gastropoda includes snails and slugs of all kinds and all sizes from microscopic to Achatina achatina, the largest known land gastropod. There are many thousands of species of sea snails and sea slugs, as well as freshwater snails, freshwater limpets, land snails and land slugs. The class Gastropoda contains a vast total of named species, second only to the insects in overall number. The fossil history of this class goes back to the Late Cambrian. There are 611 families of gastropods known, of which 202 are extinct and appear only in the fossil record. Kingdom: Animalia Phylum: Mollusca Class: Gastropoda Order: Sorbeoconcha Family: Turritellidae Genus: Turritella Species: plebia
  12. How to hunt at Popes Creek

    I've never been to Popes Creek on the Maryland side and wondered how people hunt there. Must you use a boat or can you drive and park there? Google maps doesn't show any good areas to park as I have read to stay away from the restaurants. Is it all private land? Do folks hunt north or south of the restaurants?
  13. I found this article in the news recently: http://www.fox5dc.com/news/local-news/shark-teeth-fossils-stolen-from-southern-md-home I know that if those were my finds I would feel absolutely miserable, and I could only imagine what losing year's worth of collecting must feel like. Anyways, I thought it would be good to put this information out there so if anyone sees this and has any information they could go a long way in helping this poor person. As a side note, perhaps we could use this incident to secure our own collections. It may seem odd why some burglar would steal rocks and teeth, but it's a crazy world and a few simple steps now might save a lot of pain later on.

  15. Hello all! I found a few of these, does anyone know what they are? Thanks!
  16. I got a surprise at the end of August when I received notice from the Smithsonian Museum of Natural History regarding them returning one of my fossils. Part of my surprise was that I have been dealing almost exclusively with the Calvert Marine Museum (the CMM) in Maryland for several years. Occasionally some of my specimens are sent to the Smithsonian from the CMM, but they are returned back to the CMM. The surprise was compounded when the accompanying letter stated it was an item I had sent in for identification. It was a section of bone that I found in the vicinity of Brownie’s Beach in Calvert County, Maryland. Most of the fossil material found there comes out of “Zone 10” of the Calvert Formation. The Calvert Formation is Lower Middle Miocene in age. The piece of bone was identified as part of a land mammal ischium. In Florida, with its wealth of terrestrial fossils, this would hardly be worth mentioning. In the Maryland Miocene deposits, terrestrial material is very rare. I can attest that it is a fossil that I found, but I do not remember sending it in for identification. I was starting to wonder if my memory was developing gaps in the paleontology section. The mystery was solved when I saw the acceptance date for the fossil. The Smithsonian received the specimen on April 14th, 1991 and it was returned to me on October 7th, 2017. I do not claim to be a mathematician, but I am quite proficient at basic math. The reason I did not remember submitting this particular specimen to the Smithsonian is that it was sent twenty six and a half years ago. I will be donating it to the Calvert Marine Museum on my next visit. The Specimen
  17. Well i went out on the Pax today and the mud that has been covering the beach from the high tides a couple weeks ago is finally almost gone. I got to look at some material that has been buried under all that mud and came away with a 2" mako that as you can see was trying its best to hide from me and a bunch of other teeth too all in all not a bad trip!
  18. Octopus?

    Can somebody help identify this and give me an idea how old it is? I found it on a dirt road about a mile from the Potomac River in Western Maryland, and about 1000 feet up on a ridge. I can see 8 arms (one is hard to see, along the edge), so I am thinking this is the arms of an octopus, or something related to it. But the arms are rather short, and they seem to radiate out like a sea anenome, so maybe not. This is my first ever fossil find.

    Collected from matrix in the Chesapeake Bay that was deposited by landslide. Donated to the Delaware Museum of Natural History.
  24. Clam

    Excavated from a block of matrix collected from below the low tide line in the Chesapeake Bay. Deposited there by landslide.
  25. Hello again! I was just wondering if this tooth is a Carcharodon Hastalis Tooth. I found it at Brownie’s Beach as I was combing the beach. Thanks for the help.
