  1. On the 1st I had the opportunity for another trip and made it out to Morton County. I was waiting until now to post the report because I wanted to finish preparing a crab to include in the report but I've been busy. I went to one Fox Hills Formation site but mostly I had sites lined up from the Paleocene Cannonball Formation and some Fort Union Group formations. Compared to Emmons County across the Missouri River there is less Fox Hills Formation and it is replaced mostly by the overlying Hell Creek Formation and Paleocene units. Some scenery showing outcrops of the Cannonball Form
  2. 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.

    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"):
  4. 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.

    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 i

    Douglas Point 3-7-21

    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

    Purse 2/25 - So-so finds

    Managed to get out last week to Purse to collect the low tide. After talking to a couple of nice game wardens at the lot, I headed down to the river. Turns out I had the place to myself. Conditions were very good and the sun came out after a week of nasty winter weather. My hopes were high! Well, being in no particular hurry, I was able to look at every square inch of beach and every slump pile. But I didn't find a lot, and nothing I found was spectacular. I did collect a few pretty teeth and some bits of bone, but nothing big. Just one of those days. I did share some teeth with a lady and he

    Mystery jaw - Maryland Potomac

    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?

    PG county Aquia (one more time)

    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

    Potomac River Micros

    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

    Best day yet on the creek!

    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

    Mystery Bone Fragments?

    So, I know bone fragments are notoriously hard / impossible to fully identify. Unfortunately, they are my favorite things to pick up I am happy with most of my collection remaining unknown, but there are a couple pieces I feel may have more identifying characteristics? I'm very new to identifying fossils so please let me know if its something obvious or if they aren't even bone fragments to begin with! I will describe each piece and then post photos below. 1. Found at Douglas Point, Nanjemoy WMA in Maryland. Less than an inch long, black, grooved, shiny, looks a lot like many of m

    titanoboa vertebra

    It's been nearly two years since last I posted, but I'm back with one of my latest creations, a lifesize replica of a bone from Titanoboa cerrejonensis. The smaller bone next to it is a vertebra from a(n estimated) 10-12-foot anaconda which I used for reference. Enjoy!
  14. Paleocene plants in Central North Dakota are among the first fossils I've collected. Despite this I haven't given them the attention they are due lately. The preservation is very nice but due to various reasons they've taken a back seat to other outcrops in the state like the Cretaceous ones and I haven't thought about them for awhile. I am now reorganizing some of my Paleocene collection and a spark was reignited in me. I've decided to post some of the best examples here as a result. Come spring hopefully I can collect in additional Fort Union sites. The terrestrial Paleocene depo

    Potomac tooth ID?

    I found both of these on the Potomac in a unique site with Paleocene Eocene AND Miocene exposures. I was not able to identify them, does anyone know what they could be?
  16. Hi all, I just made my first trip out to Purse State Park/Nanjemoy WMA in Maryland. I found quite a lot of sand tiger teeth, but a couple pieces I could use some help to ID. I’ve got a photo of all of them and some close-ups of each one. #1 is clearly bone, and I suspect reptile, but turtle or crocodile? #2 appears to have some glossy enamel covering on one part but is this a severely damaged shark tooth or something else? #3 had more of a tortuous, twisted crown than any of the sand tigers I found. Could this still be sand tiger or possibly goblin shark? #4 looks like it could be part of a pl

    Shark Tooth Hunting in the Potomac

    A few weeks ago my girlfriend and I decided to take advantage of the unusually warm December weather in Northern Virginia to visit the historic Stratford Hall and make a couple quick stops at the Miocene deposits in Westmoreland State Park and Stratford Hall and the Paleocene deposits in Purse State Park. To say the least, this trip was planned a bit on a whim. I was thoroughly unprepared - lacking boots or waders and having to buy a cheap plastic colander at Target to do some sifting. Luckily the Potomac River was cold, but not that cold, so I was able to wade out in my bare feet up to about

    PG county

    Ok I think I’m gonna be posting fairly regularly on this site from now on. So I’m a DC native, which means that the amount of fossils in dc are mostly sparse. However, neighboring PG county is a hotbed for all types of stuff! In the future, I’ll post my dinosaur stuff from here (still on my bucket list to find a tooth). In the mean time, I’ve just recently came back from southern PG county and I came away with some pretty cool stuff. The shells that come out of this creek are to die for. They’re some of the most intresting I’ve ever seen! But what I’m really excited about are the shark teeth!

    Potomic Paleocene Teeth ID Help Request

    I recently took a trip to Purse State Park, MD, U.S. and found this tooth fossil that I cannot identify. Because of the location (Potomic River), I assume it is Paleocene era. The fossil is 13 mm (0.5 inches) across. The pictures are of each side. Please help me identify this fossil.
