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.

From the album: Sharks
An Eocene Mackerel shark closely related to the mako and white sharks. It may have evolved from I. inflata. -
Sometime last week I went to a creek in Southeast Alabama to find shark teeth. I got thirty nine teeth and what I believe is a partial glyptodon scute. I believe that the majority are sandtiger teeth (but from YouTube and online images could be goblin) and a few mackerel shark teeth. I also got my first tiger shark tooth from this site. I was hoping someone here could help identify the scute and supposed sandtiger teeth.

Looking for help to identify the species of shark this tooth came from. I think I know, but am not 100% certain. This tooth is from southern Maryland, from an unknown location that seems to have Eocene material. I'm 100% certain that it is Eocene based on other fossil specimens I have found that are only characteristic of Eocene and not Paleocene. Anyhow, this tooth is 7/8" inch long. Daryl.

Hello all, The following photos are from my most recent trip to Big Brook, NJ. For anyone unfamiliar with Big Brook, it contains late cretaceous fossils (approximately 65 million years old). From my understanding in descriptions of formations, I recovered these from the Mt. Laurel formation. I have made better finds than this, but I wanted to share this due to its recency and the fact that I had found my favorite tooth (so far). The first Image is everything I've found, which includes mackerel (C. appendiculata), goblin, and crow shark teeth (S. pristodontus). I remember at least one S. kaupi, though it is difficult to see the enamel notch in the photo I took. In the lower right corner are an Enchodus petrosus (salmonoid) fang (in rough shape) and an Anomaeodus phasolus (early drum fish) crusher plate. Above the salmon fang are two snail shell casts and a partial cast of a snail shell. The top right corner of the overview has a mammalian tooth, not fossilized. The land in the area was once used as farmland, so that tooth may or may not be related to that. The second picture is a Cretolamna appendiculata tooth (my favorite kind of mackerel shark tooth), and the third a close up of it. The close-up was taken by using a jeweler's loupe to view more detail. The last picture is the snail shell next to a dime for scale. My sources for identification are: Joe Cocke's "Fossil Shark Teeth of the World: A Collector's Guide" (used for the Shark teeth) and NJfossils.net (for cross reference for shark teeth identification, and non-shark fossils). If anyone has any clarifications or corrections for me I am always open to learning. If I have the time I'll do a "year in review post" of some of my best finds to share with everyone. Thanks for viewing. Happy to participate in the community. - Steve
