Having the opportunity to review some literature today, I came across an interesting figure that I had not noticed beforehand. In their paper describing the fauna of a Severn Formation locality in Maryland, Harstein et al. (1999) include a photograph of a tooth assigned to Deinosuchus rugosus (Specimen 59). This struck me as strange since the Maastrichtian is typically considered to be early to middle Maastrichtian in age. However, from what I gather it seems that the youngest confirmed occurrences of Deinosuchus are in the late Campanian. Have I missed some literature and is Deinosuchus known to occur in Maastrichtian strata? It may also be important to note that in the paper, the particular lens where the tooth was found is described as a thin lag layer occurring at the contact between the Severn Formation (Maastrichtian) and the Matawan Formation (Campanian). I am inclined to believe that the fossils are from the Severn Formation and that they are indeed Maastrichtian in age, but is it possible that they may instead be from the Matawan formation? As always, any expertise is greatly appreciated . Hartstein, E. F., Decina, L. E., & Keil, R. F. (1999). A Late Cretaceous (Severn Formation) Vertebrate Assemblage from Bowie, Maryland.

For my first trip out to Calvert Cliffs for the “Season”, I took my girlfriend out to kayak along the cliffs for her first ever fossil hunting trip in the area. She had gone with me to Douglas Point once before and had good luck, so she was excited to go and see the Calvert Cliffs. We launched around sunrise and did a little leisure kayaking before making our way to the beach, water was a little rough but it was a nice morning. Hunting started slow with only a few small teeth being found, but things started to pick up after I had found two really nice size Hemis the largest being 1.47” and a nice little dolphin tooth. Then while I was searching the waterline I hear her shriek behind me and turn to see her holding her first Megalodon (or chub)! It was sitting right on top of the sand not but a few inches from the base of the cliffs. It measured 2.03” and is in great condition and I couldn’t be more happy for (jealous of) her! Needless to say she is hooked. Being my first trip out since March this gets my hopes up for a great season and I’m looking forward to going out some more over the next few months!

Trying to remember a site - La Plata MD beach on the Chesapeake?
ebfossilhound posted a topic in Fossil Hunting Trips
Hi all - I’m trying to remember a site I went to a long time ago. It was with a Delaware Rock & Mineral group to a spot that I think was called La Plata? La Plata is a town in Maryland but I’m not sure of the specific site nearby. I think it was a pebbly beach-like site on the Chesapeake that had a lot of ray mouth plate fossils. Does anyone know where this might be? -

Found a curved bone that is quite large in the Miocene formation of Calvert cliffs. Any ID help appreciated!

Hi everyone! My name is Kerry and I am a newbie fossil hunter located in central Maryland. My son has a long interest in dinosaurs (he is taking paleontology in college this coming fall!) and fossils generally, but he recently has taken an interest in fossil hunting. We went on our first expedition this weekend, and are looking to do fossil hunting more regularly! I'm generally up for hiking, digging in the dirt, cracking rocks, and carrying heavy stuff, but right now my son is most interested in finding trilobites. Any advice about good sites for locating trilobites in the Midatlantic region would be most welcome. We went to the Kinzers formation near Lancaster, PA, and didn't find much but still had a good time. Kerry

Greetings everyone, I have finally had a chance to sort through my Aquia Formation material and to put proper labels to these specimens. Although I have hunted at Purse State Park and Douglas Point several times, I have not done much in the way of identifying specimens and am quite new when it comes to this area. Responses to a previous post in which I sought identification of some specimens has been quite helpful, and hopefully my tentative identifications of this batch are more accurate than before. All specimens came from the Douglas Point area and I have used Elasmo as my primary reference for tentative shark tooth identification. I extend my gratitude to all who view this post and help with pinpointing accurate IDs for these pieces! I will tag a few members who are knowledgeable in this area: @MarcoSr @Al Dente @bthemoose @cck @Bjohn170. A Specimens: All of the specimens pictured above, which for convenience I will refer to as '1a-49a', seem to be Striatolamia sp. If sharper images are needed or if photographs of individual specimens would be helpful, I would be glad to provide some. B Specimens: I cannot say for sure what these teeth belong to. They - or some of them - could very well be Striatolamia sp., but I felt inclined to tentatively label them as Hypotodus verticalis. C Specimens: These all appear to be myliobatid dental plates. Can a more specific identification be given for any of the above specimens or should they simply be labeled as myliobatid? D Specimens: 1c and 3c very closely resemble crocodilian teeth and I have placed 2c along with the others due to the striations on its surface. I have heard that Eosuchus minor is known from the Aquia Formation along with another species of crocodile. Are there any diagnostic characteristics that would allow these teeth to be attributed to a specific crocodilian? Specimen E: This tooth looked quite different from any others that I have included in previous photographs. I have tentatively identified specimen E as Odontaspis winkleri due to the double cusps but I have a low level of confidence in this ID. Specimen F: Appears to be either a ray or chimera fin spine. I recall having come across a post in which @MarcoSr identified a similar specimen as pertaining to a ray rather than a chimera. Specimen G: A possible bony fish element? I do not know if a more specific identification can be given. Specimen H: Pyconodont fish mouth plate? Specimen I: A very small yet curious piece that I found while sifting with a very fine screen. I am unsure whether this is a fossil or whether it is simply a geologic oddity. Specimen J: Fish jaw section?

I found this enamel fragment along the Calvert Cliffs (Miocene) in Maryland, USA, some time ago. I'm not sure what it came from--croc, odontocete, other?--but am hoping the horizontal ridge between the top and bottom halves, or perhaps other features, may be diagnostic. Anyone recognize this or have ideas on what it may have belonged to?

In sorting through some of my previously unidentified Maryland, USA, shark teeth from the Aquia Formation (Paleocene), I found the small tooth below, which looks like it may be an extreme posterior tooth from an Otodus obliquus shark. It's missing a cusplet, but the shape of the remaining cusplet, cusp, and root all remind me of Otodus or possibly Cretalamna sp., which is also present in the formation. If this is an Otodus, it's definitely the smallest one I've found. @MarcoSr and others, what do you think? Here are several views: And here it is next to my largest Otodus (measuring 48.6 mm on the slant) from the same location.

I picked up this little bean-shaped thing, 10+ years ago, from a beach in either Charles or Calvert County. I can't find any modern beans or seeds that look like this. Ideas?

I found what I think are some mosasaur parts in Maryland. The site I was looking is an ~80 MYO marine site in the severn formation in Prince George's county just outside of DC. Here are a few pictures of the best pieces - a big tooth, nice neural spine, and a smaller vert. Am I correct thinking this is mosasaur? If so, potentially either a Prognathodon or a Hoffmanni? These are not in the best state of preservation, but typical for this location.

Here are some of the cool things I have found over the years!

Took a trip down to the Calvert Cliffs with the Buffalo Geological Society last weekend for some fossil hunting. It was my first time ever hunting at this location and I would call it a success. I can see why this location is such a popular spot, great beaches along the Chesapeake and beautiful weather made this one of the most scenic fossil hunting locations I've ever been at. The first day was Flag Ponds, which is where most people had better luck finding good sized shark teeth during low tide conditions. I found a small fragment of a Meg here, which was exciting. The second day was Matoaka Cabins, which was where much better invertebrate shells could be found. I took a walk a bit past a recent cliff failure and ended up having a lot of success finding teeth during high tide by churning up the sand and letting the waves wash it out. After I got a system down in the afternoon, this method yielded me a tooth every 5 to 10 minutes. I also filled a 3gal bucket with gravel deposits from the low tide to bring home and sift, I would not do this again as I only found a few teeth from this bucket. Looking forward to the next time I can get back. Total finds. Everything above the coral is from Matoaka, everything below the coral is from Flag Ponds Dolphin ear bone, probably my favorite find of the trip. Awesome preservation from what I have seen Some of the best teeth Some of the better ray fossils Crab claws Bones

Hi, all. I found this on a beach in Maryland and thought it might be something cool. Or just a rock. Started googling around and found you all! I'm an absolute beginner. Let me know what you think. Happy to answer any questions.

I used to hunt Paint Branch Stream in College Park MD for fossils as a child (slightly before the Ray Stanford nodosaur find) and never found much. I returned after many years today (place was really bulldozed, shame) and found a great section of formation and tons of wood impression and lignite fossils. Also found two magnificent flat, thin possible footprints. I’m attaching the best one of which I dropped and broke to my great dismay. Let me know if you need additional shots or angles. I really want some insight on if it is a track. Notice that the clean break revealed the cross section which showed folds and sunken areas that match up perfectly with the “track”. Thanks in advance, I’m new here

Hi! I went on my first fossil hunt yesterday! Found two cool shells, some pretty quartz, a few rocks but no fossils. Here are my finds! I was wondering what i should look for when hunting along and in the potomac! Was hard to find stuff when I wasn’t sure what to look for haha! ^^ im 16 so I cant go often but im going to be begging my parents to take me again soon because i found pottery too! (Its not old but i find it interesting ^^)

I found this specimen recently and have been perplexed by it for a while. To me it appears to be a tooth, though if it were I don't know from what. I looked at it from under my loop and it does have some small dimples in it, and is made of shiny black material, which is what drew me to that possibility in the first place. It looks similar to teeth I've seen posted on the forum before, especially in the Pennsylvanian shark tooth topics. I did some searching and oddly enough ended up finding images from a ptychotrygon. I don't know what it is exactly, but form the images it has a resemblance to that shape. I tried taking the best pictures I could, but the object is pretty small. So I guess my questions are if it's actually a tooth and, if it is, what kind is it? It comes from the early Cretaceous Potomac Group, Patuxent (?) Formation (possibly Arundel however) from near Washington DC. Thanks for any help!

I found what I believe is a partial fish tooth along the Calvert Cliffs (Miocene) in Maryland a while ago. @Al Dente, @MarcoSr, or others, any idea what this may have belonged to?

Hi! I found this by the potomac river, maryland! Was wondering if this could be a fragment of something or just a cool rock with some layers! Thank you.

Hello to all ! I've never been on a forum before so please excuse any ignorance of protocol, thanks in advance. I was recommended this from Rock Seekers because I have been interested in both rocks and fossils for most of my life. I'm a 64 year old retired RN that grew up living all over the place. My father was career military and also a Master Naturalist for the state of Mississippi, so we got to dig for stuff all over the world. Very lucky for me ! Fortunately, I get to go out west every year and dig in Wyoming, Idaho, South Dakota and Montana with my brother. I've attached a few pictures of some of my stuff, just finished moving so it's not all unpacked yet. Thanks for allowing me to join, I look forward to being on frequently.

Just observing both shark teeth side by side. The heterodontus teeth have rounder cusps and a textured enamel near the root, similar to what you see on top of their crushing teeth.
