Hello, my friends, and a jolly warm welcome to one and all. Many moons ago, my friend, the exceedingly kind and generous Brett @Elmo sent me nearly 6 lbs of micromatrix from the Purse State Park in Maryland, USA. The tiny fossils found in this gravel are from the Piscataway Member of the Aquia Formation which is Late Palaeocene in age and about 60 million years old, give or take. I have been trying to sort through a little every day and am about two-thirds of the way through and have found lots and lots of goodies. Now, this is well out of my comfort zone as there is not a brachiopod to be seen, but lots of teethies from sharks, rays, skates, and bony fish. I have no idea what I am doing at all, and so Brett, who is also seeking some IDs, and I decided it might be useful and fun to start a thread to show off our finds, hopefully get some help with identification, encourage others to post their own finds and have a fun time, really. I don't have any Palaeocene material at all, except a couple of larger sharks' teeth from this location. So, please feel free to comment, just watch and enjoy or tell me off for my obviously stupid attempts at ID. I'll start this off with a really beautiful tooth that I think might be Delpitoscyllium africanum. On second thoughts, perhaps Ginglymostoma cf. subafricanum is a better fit? Because of the multiple side cusps.

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. And that wasn't the only one -- as it says in the thread title, today was an Otodus kind of day. #3 #4 #5 Yep, still going -- #6, which was in the best shape: And finally, lucky #7, which I found on somewhat higher and drier ground: I didn't only find Otodus today. There were also quite a few nice and sharp sand tigers. I often find large Striatolamia striata roots with broken crowns. But this one was complete! It doesn't hit the magical 2-inch mark, but at 1.7 inches, it is my largest sand tiger find to date. You can't tell in the photo, but the blade is sharp and the tooth is in quite good condition. I found another tooth that at 1.5 inches is also quite large, though this one's more river worn. Beyond shark teeth, I found a nice ray plate. There were also beautiful butterflies. All in all, it was a rather splendid day!

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 used the Striatolamia macrota artificial tooth set on elasmo.com as my guide. I'm sure some of the teeth in my reconstruction are out of place, including some of the upper or lower teeth possibly being from the opposite jaw instead. I couldn't properly size match the intermediates and first lower anteriors, but can always swap in replacements if I find them. One of the extreme posteriors is also reversed in the display (labial side showing rather than lingual like the rest) as I'm still missing a tooth from that position. Overall, I'm quite pleased with the result. This is my first artificial tooth set, and it was a fun project that taught me a lot about tooth positions! Here's the full tooth set -- the largest teeth in the display are just over an inch long: Left and right sides: Quadrants: The final riker display:
