I will introduce this article by quoting the last sentence: "The place has been the site of fossil finds since the 1980s, and many of the discoveries - like this latest one - are made by dedicated amateur palaeontologists." LINK to article

Hey everyone, realizing right now that I haven't posted any fossils of my own in quite a while on the forum. Anyway, I found this tooth back in 2016 on my trip to the potomac river in maryland. It was found at purse state park which has exposures of the paleocene Aquia formation. When I first took a closer look at this tooth I was surprised to see that it had a shape which I had associated with Tiger sharks. I did some research online and found that Pachygaleus would be a match as they are present in that strata. It has been a while since that initial discovery but I wanted to confirm my idea

So I was rooting again around in the garage and found a couple plates I had bought a few years back and never tracked down an ID for. Tentative provenance was Paleocene from Montana. I found this article recently and was wondering if it could be one of the genera/sp described or one of the other genera mentioned in the discussion section. Trapa, Trapago, Fortuna, Quereuxia. STOCKEY, R. A., AND G. W. ROTHWELL. 1997. The aquatic angiosperm Trapago angulata from the Upper Cretaceous (Maastrichtian) St. Mary River Formation of southern Alberta. Int. J. Pl. Sci. 158: 83-94.

Long time dream comes to fruition!
FossilDAWG posted a topic in Partners in Paleontology - Member Contributions to Science
Long ago, back in the late 1980s, I lived in British Columbia and had the opportunity to collect in the Late Cretaceous Nanaimo Group. I realized that many of the crabs and lobsters I was collecting were undescribed, so I made an effort to collect any material I came across. I tried to find a collaborator willing to help describe the material, but (for reasons I described elsewhere) that didn't work out, and I was encouraged to take on the writing myself. Since I had to focus on my own research career, which actually has nothing to do with paleontology, the project languished and over time- 31 replies

At 1400 hours on 10/13/2018, I collected a number of specimens from the Tullock Member of the Fort Union Formation. The location is about a mile north of Miles City. The rock is fine silty clay with leaves and twigs mixed into the sediment. Above the strata is a layer of cattails forming a matted layer. Source for leaf identification came from Reproductive and Vegetative Organs of Browniea gen. n. (Nyssaceae) from the Paleocene of North America Article in International Journal of Plant Sciences, February 2007.

Nothing to crazy going on today. My wife found this piece of bone and she wants to know what it is. My initial thought is it was some random piece of croc but now that I’m looking at it closer I’m really unsure. Take a look tell me what you think

After the long month without fossil hunting, we decided to go to Purse on a free weekend. Now that it is a former state park, it's a lot harder to find because there is no address to it, so hopefully it can recover from some of the hunting that has taken place upon it's shores. I really, really wanted some nice Macrotas after all the talk I had heard about them, and thankfully, Purse didn't disappoint. It was the middle of hunting season there, and we werent wearing anything particularly bright, it was a little nerve racking hearing the boom of gunshots far of in the distance. We started by go

Shark Tooth ID help- Cretolamna sp. (appendiculata?) or Otodus obliquus?
PB&J Mama posted a topic in Fossil ID
Hello All! I found this shark tooth at Purse State Park in Charles County, MD. Located on the Potomac River, these fossils are from the Aquia Formation. As a novice fossil hunter, I would love some help in identifying this tooth. Is this a Cretolamna sp. (appendiculata?) or Otodus obliquus? Thanks so much in advance! ~Natalie- 3 replies

PaleoNoel's Fossil Hunting Chronicles: Potomac of Maryland, April 2016
PaleoNoel posted a topic in Fossil Hunting Trips
I would consider 2016 to be the year that my fossil hunting career really took off, I had spent trips prior to this grooming and developing my skills and it began to show in this period. My school vacations have always been the time where I've been able to get out into the field and go fossil hunting, this particular opportunity was afforded to me by my class trip to Washington D.C. which then lead into my April vacation. Having devised a plan to go fossil hunting before leaving, my dad picked me up at the end of the DC visit before the rest of the group took the grueling bus ride back to -
I am looking for some help IDing these leaves. They were collected less than a mile north of Miles City. They came out of the Tullock Member of the Fort Union Formation. They are Paleocene, Danian age. These leaf fossils were with Sequoia and grass leaves.

In the current (July-August 2018) issue of American Scientist magazine there's an article on champsosaurs. Anyone who's collected Late Cretaceous fossils in Montana, the Dakotas, Wyoming, or southern Canada has probably found a few. You tend to get just a paragraph or two about the group in mainstream science articles about animals that survived the K/T extinctions but there's a whole article about them. Check out your local Barnes & Noble if you don't have online access.

I just have to brag about @Ptychodus04 a bit more. This man is a master at preparing fossil fish. Someday I hope to be a fraction as good as he is. Here's what he ended up with on the Priscacara I sent him. This was not an easy prep. The right side was completely covered with matrix and the left side exposed. He glued the pieces back together and started prepping on the right side top down. Excellent job Kris. Here's what he sent me.

FYI @Ptychodus04 @RJB I have some Herkimer Green River Formation fish I just dug up last month and they look really nice but half of them are covered in the sedimentary limestone. There's a bunch that are halfway covered. The matrix is real sticky and just doesn't want to come off. I tried pulling off chunks with some dental tools but had to quickly stop as that was damaging the fossil. Every time I pull up a chunk it takes the fossil with it. I'm thinking about getting a nice air scribe. I found a nice Chicago Pneumatic CP-9361 but have heard that these scribes can be tough on fos

Fossil Forum Friends, I put some fish up for possible trading on the trades section and wise @Fossildude19 reached out to me with a possible identification as a Amphiplaga brachyptera. This species makes up less than 1% of the known fish collected in the Green River Formation. Upon closer inspection it appears to be that species or it might just be a disarticulated Knightia. I really can't tell as I'm not a fish expert. Please provide your input. If it is a A. brachyptera can someone please PM me with a quote for preparing the fish and once it's prepared I'll get it framed at Michael's cr

Found today and at first thought it was a Paleocene Croc Scapula. But, a FB member mentioned it could be a Paleocene mammal Talus. Thanks for looking, Any and all advice is appreciated Paleocene, Aquia Formation, Maryland
-
Anyone want to hazard a guess on this one? Its an undulating series of ridges and depressions uniform in size. The matrix has an ash character to it. It has a calcareous look but fails the vinegar test. Probably marine in origin. The only other fossil associated with it was a very small turritella impression. Found south of Thomasville, Alabama which makes it Paleocene.

Went for my first time to purse state park proper (Douglas point is my usual Potomac haunt). Mostly for micro, but I did a bit of surface hunting. Found this beautiful vert, find of the day by far (disappointing otherwise). I’ve no clue what it is, though I assume some sort of gharial. My quick research brought me to eosuchus being the best candidate. With a surprising resemblance to champsosaurus but I think that’s unlikely. Any ideas? Gonna go ahead and tag @MarcoSr. Thanks!

A couple of weeks ago I stopped by Blue Banks, just north of Purse State Park MD. The Paleocene Aquia Formation is exposed there, and teeth and bones of a variety of species erode from the exposures and accumulate in gravel along the shore. Unfortunately the Potomac River was in flood stage, so the gravel along the shore was submerged despite the low tide. A driving rain storm did not help matters. I scooped gravel and passed it through a couple of screens, and recovered a handful of the usual small sand tigers and ray teeth, before calling it quits after an hour or so. The following was
