I found this perfect little tooth today along the Potomac River in Maryland (Paleocene, Aquia Formation), which I think may be an Otodus obliquus parasymphyseal. The root isn't as oversized as megatooth shark parasymphyseals I've seen posted elsewhere on the forum, but it sure looks like an Otodus, is laterally compressed, and is quite tiny compared to other Otodus I've found. @MarcoSr, @siteseer, @Al Dente, and others, what do you think? This tooth bears similarities to another I found from this location several weeks ago (tooth on the right

here are some stuff that I found in the aquia formation over the weekend. this button is weird to me, my gut tells me it might be a vert, but it could also be a fish tooth perhaps? this is a weird one, it looks like a Galeocerdo tiger shark, but i havent read anything of these existing at the Aquia formation, much less finding them at purse. bone fragments? would it be possible to tell if its reptile bone? this bone is interesting because it has some underside of its surface still intact. it almost reminds me of

Hi all. This past Thursday I made it out to Douglas Point (Paleocene, Aquia Formation). I found the usual assortment of sand tiger shark teeth and some goblin shark teeth too. Unfortunately, finding an Otodus in this formation still eludes me. First is a picture of all my finds. What I'd like some ID help with are the vertebrae, the two bone fragments, and the crocodile tooth. The last tooth is an interesting one. Looks like a Hemipristis serra tooth to me, though I didn't think they're found in this formation. I included an in-situ photo with the characteristic Douglas/Purse grav

This past Thursday, I made a trip out to Douglas Point along the Potomac. I enjoy going in warm weather like anyone, but going during the winter has its own merits. Cool, crisp air, fewer people, possibly some more unique finds. I was the only one on the beach for just about the whole morning and afternoon. Although a little chilly, the right gear made it no problem at all. The trail down to the beach is a bit run down. Lots of broken and collapsed trees covering the trail. I found quite a few sand tiger teeth. I only keep the larger ones now that I find and leave the

I was fortunate to find an excellent Palaeocarcharodon orientalis tooth this morning at Douglas Point (Paleocene, Aquia Formation) in Maryland. I thought it was an Otodus obliquus at first but then I bent down and saw the serrations. The tip is a little dinged, but it has a solid root, shiny enamel, both cusplets, and those classic ragged serrations. At a little over 34 mm long, it's quite large for the site. I also found my first section of fossilized croc jaw (also just over 34 mm long) today, which still has two teet

I made it out to the Potomac yesterday in Maryland and finally found a 2" (almost) Otodus obliquus tooth! IMG_5728.mp4 It's worn and missing both cusplets unfortunately (have to have a reason to keep looking, right?), but this has been near the top of my Maryland bucket list fossils. It's tad less than 2" (1.91"/48.6 mm), but also very wide (1.38"/35.1 mm) with a nice chunky root. I'll round up. Here it is next to my previous largest Otodus personal find (1.59"/40.4 mm), from February. The new one is

After going several weeks without fossil hunting, due to weather, schedule, etc., I finally made it out to Douglas Point (Paleocene, Aquia Formation) in Maryland this morning on a very pretty, cool autumn day. My first fossil find of the day was a small piece of ratfish plate. Below is my first shark tooth of the day (a sand tiger, like the vast majority of teeth found here). By the standards of this site, the quantity of shark teeth was low today, but they were in better than average shape, which isn't a bad trade off. Many appeared to be fres

Here I have attached pictures of a recent find I made in Maryland’s Aquia Formation. It’s a Paleocene bone from what I think is a turtle. What do y’all think? It’s very thin whatever it is.

I found the tooth below a couple of months ago at a Maryland Paleocene (Aquia Formation) site. Am I correct that it's Hypotodus verticalis? Thanks in advance for your help! The tooth measures just under 28 mm on the slant.

I went out to Douglas Point (Paleocene, Aquia Formation) in Maryland yesterday to see what fossils the recent rains helped bring out. I tried last weekend as well, but I didn't find a ton as it was too close to the storms and the Potomac River was running choppy and high with little beach exposed, even at low tide. Yesterday the water was calmer and lower and I had a more successful hunt. It's definitely the time of year for snakes! (They're almost all non-venomous around here.) I encountered this one a few minutes into my hunt and saw four others throughout the day.

I found the small bone below yesterday while out at Douglas Point in Maryland, which exposes the Aquia Formation (Paleocene - Thanetian). It has the look and feel of fossilized bones from the area and it passed the burn test, so I'm fairly sure it's a fossil. This is the most complete bone I've found at this site. Any ideas what it might be from? Side 1: Side 2: Side 3: Side 4: Ends:

Went out to Douglas Point (Potomac River, MD, Paleocene, Aquia Formation) on June 5th, first time taking the kids and we had a great time. Found a lot of sand tiger teeth as is typical. But this one has me a little stumped. The crown seems too wide at the base to be a sand tiger tooth. Could it be a small or juvenile Otodus? Or is it some kind of sand tiger after all?

I made a trip out to Douglas Point today and had one of those incredible fossil days that just makes you want to head out over and over again. There were two cars in the lot already when I arrived early this morning but their occupants must have been up to something else because I never saw them and I had the beach all to myself for most of the day. It was a chilly but beautiful morning on the banks of the Potomac. There's just no better sight at Douglas Point than a nice Otodus obliquus tooth waiting for you in the sand.

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"):

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 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 i

I made it out to Douglas Point on the Potomac River yesterday morning for a chilly Maryland Paleocene (Aquia Formation) fossil hunt. Temperatures started in the upper 20s Fahrenheit and eventually climbed into the more comfortable 40s though by that time the tide had substantially come in. The banks of the river were ice free but the sand was hard packed and frozen. The pickings were fairly slim by this site's standards, which means I found dozens rather than hundreds of shark teeth over roughly 4 hours. No spectacular finds on this trip, though I found a decent enough variety, and

This was found at the Virginia/Maryland Aquia Formation, Potomac River. It’s about 3 inches (7.6 cm) long and 1.5 inches (3.8 cm) wide. I have an idea of what I think/want it to be but would like the opinion of someone more experienced. Thanks for any help!

I recently brought home a gallon bag of Potomac River gravels (Paleocene, Aquia Formation), and have been searching through them for micros using my new digital microscope (the quite reasonably priced Plugable USB 2.0 Digital Microscope, which several others on TFF have recommended). I've found a number of shark teeth and have tentatively IDed many of them, though would appreciate corrections or confirmations, as well as thoughts on the unidentified ones. The tick marks in all of the photos below are millimeters. Thanks in advance for your help! 1. Abdounia

For years I’ve had my macro fossils in drawers and my micro fossils in gem jar displays. Recently I’ve started putting some of my macro fossils in 8”X12” Riker mounts. Below are the Riker mounts that I now have. I’ll probably put together at least twenty of these. Below are two Riker mount displays with specimens from the Paleocene Aquia Formation from the Potomac River in the Liverpool Point, Maryland area. This display contains in the top crocodile vertebrae, a couple of crocodile leg bones, and two crocodile coprolites. I have larger crocodile vertebrae but they- 20 replies

I’ve recently bought some fossil shark teeth online to expand my collection beyond the local Maryland fauna (Miocene from the Calvert Cliffs and Paleocene from the Potomac River/Aquia Formation), and it occurred to me that perhaps there are some forum members who would be interested in sharing some of your finds or extras in exchange for mine. The things I have to offer are shown below—mostly fossil shark teeth and a few other things. These aren’t all perfect, but there’s a good variety, including some less common species. I’ve collected most of these myself and have also listed a

I found the tooth below this morning at Douglas Point (Aquia Formation, Paleocene) in Maryland. The cusp is fairly narrow, it's missing one cusplet and the other is small and/or worn down. But between the prominent lingual protuberance and what looks to me like a small bourlette, I'm getting an Otodus obliquus vibe. What do you think? I also found a tiny Cretalamna appendiculata -- just over a quarter of an inch.

Found this partial ray tooth plate in January while fossil hunting in the Aquia Formation along the Potomac River. Does this look like Myliobatis dixoni to you? I am terrible at identifying ray teeth, so really not feeling certain about that ID.

Hi all, I found this chunk of bone at Purse State Park this November. It is from the Aquia Formation, which is of Paleocene Age. I was wondering if it could be identified to either crocodile or turtle, considering that these are the only two bony vertebrates that exist in large amounts in this formation. Or, of course, it could be nailed down to chunkosaurus status considering that it is relatively worn and isn’t very large. Thanks in advance!
