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.

Finally ... a discussion of fossil sharks from Morocco and transitional teeth.
Northern Sharks posted a topic in Member Collections
Santa came early here in the north country. I've been after one of these for a while and I finally got one in the mail today. It's an early, transitional form, Palaeocarcharodon orientalis. Very coarse serrations near the root fading to almost smooth at the tip. One root tip was glued back on as these teeth are very prone to damage, but I can ignore that because it's almost 2 inches long, and they don't get much bigger than that.- 156 replies

I'm finally getting around to posting pictures of this Moroccan shark tooth, which I believe is either a transitional Otodus obliquus or a transitional Palaeocarcharodon orientalis. My original thought was Otodus but @Al Dente flagged in the mailbox thread a few weeks ago that it might be Palaeocarcharodon instead. Any thoughts on this one? The tooth measures 49 mm on the slant and is 39 mm wide across the root.

I got to Purse a couple hours before low tide and got a good 5 and a half hours of searching. Managed to scrounge together over 1,000 teeth, most of them pretty small, a new personal best. I didn't find anything of significant size, but a handful of oddities/rarities. One such oddity was what looks like a Carcharhinus (Gray/Dusky Shark) of some sort. Perhaps some folks came to Purse following a hunt at Westmoreland or some other place and a tooth slipped out of their bag. This is a first for me. I found a worn down palaeocarcharodon with some nice dark blue coloration, some crocodile teeth, among other things. I found a neat little fossil of some sort that I can't identify, it's about 0.8 mm in diameter. Images: https://imgur.com/gallery/d0qdUxU

I got this tooth mixed in with a bunch of small Moroccan stuff and it struck me as something a little different. To me it bears a striking resemblance to Palaeocarcharodon, without the serrated blade. It doesn’t look right for Otodus or Cretalamna to me, it’s too delicate and thin, very much like Palaeocarcharodon. Any thoughts or suggestions on it identity would be appreciated. Happy newyear!

These teeth were found along the Potomac River in Western MD, in the Aquia formation. I am having a tough time finding information on teeth from this location but I believe these are possibly Pigmy White teeth (Palaeocarcharodon orientalis). All six show signs of serrations, but there are other teeth from the Paleocene that might look similar? I need help identify them and don't want to mislabel them in my collection. Also I found these two smaller teeth with serrations on one side but they seem unlikely to be Pigmy Whites. Any idea what they are?

Just thought I'd share a set of principal transitional Palaeocarcharodon teeth from Morocco. Love this species, one of my faves.

I was wondering what the general consensus is on what Palaeocarcharodon's ancestors are. Inwas also hoping some of you could share pics of your early or transitional palaeo teeth. cheers!
