Shark teeth from Paleocene Aquia Formation at Douglas Point, Potomac River, Maryland
traveltip1 posted a topic in Fossil Hunting Trips
This riker mount displays the best shark teeth that I collected on 3 hunts sifting at Douglas Point beach, Charles County, Maryland. This is the Paleocene Aquia Formation. Bottom row contains several Odotus teeth. There are many goblin shark Anomotodon and sand tiger shark Carcharias. Also appears to be one pygmy white shark Paleocarcharodon in lower left corner.- 9 replies

Found this cool little jaw fragment last week on the Potomac in a section that has mostly Aquia paleocene exposure but also has some eocene and miocene. There is a very tiny unerupted tooth in one of the sockets which I hope will help with ID. It's hard to get a good image but the tooth looks flattish with a rounded tip, not conical and not pointy. Any ideas?

I was going to do some more exploring of new areas (trying to find a Calvert exposure until I can get the boat in the water since everything’s closed) but I decided to go back here yet again. I made a pretty good decision I think because I found a bunch of shark teeth that are of decent size, and a killer shark and fish vertebrae. I also found a small block of Calvert formation here too, and I found a lot of it exposed on another piece of land a few weeks ago, but then turned around after seeing a bunch of “no trespassing” signs posted all up and down. Go figure. So until I find anot

This is from a two day trip to the same creek. The first trip I found some clues that there may be big teeth here due to the large ray plates I found (the first day was mostly rays so you can tell them apart kinda). I found a few small shark teeth and I called it a day. The next morning, I set out for the creek yet again and I knew I made a good decision because I was going to explore a new place. Sometimes it’s good to explore something uncharted another day. I found a lot of teeth including this beauty that tooth was absolutely flawless and came right out the formation. I found a lot more sh

Recently took a trip to Douglas Point and found this odd shaped piece in matrix. Not sure if it is anything or just some sort of concretion, appreciate any help! Thank you

I was out kayaking on a creek on the Virginia side of the Potomac today to do some birdwatching, but in an area I thought might have some Aquia exposure. I did come across one small bluff face, with maybe maybe 40 feet of narrow beach, that I stopped to check out. After about 2 minutes, I looked down and found this guy. My best Otodus so far and still razor sharp! I did find a few more much smaller teeth and a decent ray plate fragment, but nothing special the rest of the day. But this tooth--plus dozens of herons, ospreys, eagles, and purple martins, among other birds--made for an awesome

Hi, I made a few visits earlier this spring to the Potomac (Aquia formation) in Maryland and collected a bunch of shark teeth, most of which look like Striatolamia striata with quite a few likely Hypotodus verticalis as well. I'm hoping to confirm my IDs of a few potential Otodus obliquus and Cretalamna appendiculata teeth as well as get help identifying some others. The teeth in question are below--I'll include composite photos from different angles in reply posts. I've currently categorized teeth #1-3 as Otodus obliquus, #4-6 as Cretalamna appendiculata, and #9-14 as Hypotodus ve

I got to Purse a couple hours before low tide and got a good 5 and a half hours of searching. Managed to scrounge together over 1,000 teeth, most of them pretty small, a new personal best. I didn't find anything of significant size, but a handful of oddities/rarities. One such oddity was what looks like a Carcharhinus (Gray/Dusky Shark) of some sort. Perhaps some folks came to Purse following a hunt at Westmoreland or some other place and a tooth slipped out of their bag. This is a first for me. I found a worn down palaeocarcharodon with some nice dark blue coloration, some crocod

We've had a couple nice hunts in the Aquia recently. Our first trip was really nice. The weather was beautiful and the tide was low. The only finds of note from this trip were two shark vertebrae and a small yet pristine transitional otodus. As always, we found over a 100 teeth in the gentle shallows. Our second trip was incredibly productive, albeit with fast moving water and a high tide on a beach ravaged by storms. We found what I think is a turtle washing out of a recent fall; I was unable to spot the rest of the turtle in the fall, however we were able to grab five pieces of mat

Today was our first trip to a hunting spot in the Aquia Formation. We had no idea what to expect from this location, but believe me, we were not disappointed. After three hours of walking the beach and sifting, we managed to leave (when the rain started) with some really nice pieces. I managed to grab what would have been a beauty of an Otodus except for the fact that it was snapped in half, some Ratfish material, one of the teeth i've been hunting after for a while, Jaekelotodus Robustus, a croc tooth, an angel shark, and a multitude of large Striolamnia Striata.

Hello all, first post on the forums despite joining awhile ago. Last winter I was fortunate enough to have some serious luck at Purse State Park in 2 consecutive trips while I was on break. Thanks to @Williamb55I was able to finally muster some motivation to seek some help to ID what I believe is a Crocodile tooth and Otodus from the Paleocene Epoch. Of course this could be inaccurate but I would love some insight into my find, comments and replies are appreciated. Best, DF

Hi there! my name is Tim George. I am fairly new to the fossil hunting hobby and was wondering if anyone knew someone who could perhaps take me and my dad on a fossil hunting trip. I am looking for people who do tours of either the Calvert formation,Aquia formation, or the Nanjemoy formation. Thank you.

Virginia - Maryland Aquia & Nanjemoy formations dating?
kate_rose posted a topic in Questions & Answers
Hi, We are doing a unit on geology/paleontology in our homeschool with the fossils we find. I was wondering if anyone knows the difference between the Aquia and Nanjemoy formations. I know wikipedia is not perfect but I am not an expert and it lists them as separate formations albeit both from the Paleogene. I have read Paleocene/Eocene border for the Aquia formation. Is that correct? The Nanjemoy formation I had not read about before today. Is it just the same thing on the Maryland side of the River instead of the Virginia side? Thanks for the help, -
Question about shark/fish teeth and casting Aquia formation MD
kate_rose posted a topic in Fossil ID
Hello, Here are some more of our findings from our 2 brief trips to Purse Park. I think the shark teeth are Odontaspis winkleri but am not sure. I have no idea on the small cream tooth other than its probably from a fish . . . (to me it looks surprisingly rodentlike though)?? And the hollow black bit which I initially took to be a casting from an invert burrow I figured can't be since it is hollow. Anybody have any ideas?? Thanks, Kate -
Hello - I wouldn't normally post a fragment of a bone seeking help with identification given how difficult it can be to determine the specific animal with just a photo of a piece; however, I found this piece awhile back and was going through my phone looking at other pictures and realized I never posted my question. The pattern on the bone is what makes me think someone with much more knowledge about the fauna that can be found in that area might be able to make a positive identification. If not, no big deal but figured it was worth an ask. This was found amonst the rocks along the beach at Pu

I went to Purse today for a few hours and this is what I came up with. Not as impressive as last time, but I still enjoyed my day. I didn't find anything absolutely amazing, but I did find a teeny vertebra piece. I am sad though, as I had planned to head to Calvert tomorrow but unfortunately my car began acting up so I had to drive all the way back to RVA.

I'm back! A long spring break presented me with the opportunity to go out on a few fossil trips. I just haven't gotten around to posting until now. But here we go! After finding over 600 shark teeth in one day at Purse State Park, how could I not go back? With the stress of school completely absent from my mind, I went down to the park along the Potomac River for another day searching for Paleocene fossils. I arrived early, as I always try to, and I was the only one there when I arrived. Instead of heading to the left of the entrance as I did on my first trip, I decided to start by

Hello. I recently took a trip on the Potomac River south of Washington to a Paleocene site. Nothing too exciting for the most part. Lots of small shark's teeth, two smaller broken Otodus teeth. I did, however, find two oddities. Both appear to be bone, one has "ripples" in the surface reminding me of turtle shell. the other has dimples that somewhat resemble a crocodile scute, but not exactly.. Any help would be appreciated.. Thanks!! drobare

Hey all, Hope all my fellow East Coast dwellers are holding up alright after the storm. We got hit pretty hard with snow in Northern VA. Anyway, this tooth was found at my Purse State Park trip a few months back. It looks quite different from the majority of the teeth I found on my trip. I used fossilguy.com to compare it to common fossils from the Aquia Formation, and it looks very much like a Paleohypotodus rutoti tooth. Can I get any confirmation on this ID or is it something else? It is slightly over 1/2 inch, but that's with a dinged tip. It has a distinctive U-sha

These teeth were found along the Potomac River in Western MD, in the Aquia formation. I am having a tough time finding information on teeth from this location but I believe these are possibly Pigmy White teeth (Palaeocarcharodon orientalis). All six show signs of serrations, but there are other teeth from the Paleocene that might look similar? I need help identify them and don't want to mislabel them in my collection. Also I found these two smaller teeth with serrations on one side but they seem unlikely to be Pigmy Whites. Any idea what they are?

My wife and I were searching Aquia formation beaches in Virginia the other day and found these. We've no idea what they may be. Can anyone throw some knowledge our way? The first is a small (nickel sized) plate with little divots in its surface. Divot side is convex, other side is smooth and concave. (One image) The second piece is about a 3/4 of an inch long. Two opposite surfaces are smooth, and the other two opposite surfaces are grooved, kind of like wear patterns. There is a hole down the length of it that goes all the way through. Looks toothlike (three images)

Last Sunday my family (wife, 7yo son, and 2yo son) and I headed down to Purse State Park for the first time for some fossil hunting and beach time. The parking lot was full but a couple was packing up so we were able to snag their spot. We got there about and hour before low tide and stayed about 2 hours. We all found some teeth and ray crushing plate fragments. Ok, technically our 2 year old was just playing in the sand but we pointed out and he handed us the ones that were in the sand he was playing with. We didn't find anything huge but for 2 hours everyone had fun and was happy. In t
