On Friday I made a visit to an Atlanta area gem/mineral/fossil show. Generally I have poor luck at these shows, in large part because there are only a couple of dealers with fossils. This trip was different. One of the dealers was selling some items from an old collection. Most of what I bought was exciting to me because they are species I have wanted for a long time, for one reason or another. First up is a nice (to me at least) New Jersey Tiassic coelocanth, Diplurus newarki (I think the genus might have changed but Diplurus is OK for now). The dealer thought it was just a skull so it was very cheap, as the rock is very black and it was hard to see the skeleton in the room lighting. I used the flashlight on my phone to give oblique light and was very happy at what I saw! He also had some ammonites I was excited to see. Two are Triassic, a Ceratites nodosus and an Acanthoceratites spinosum from Germany. I collected a Ceratites when I was a kid (about 10) living in Germany, but it broke and all I have left is a piece. I've wanted a better specimen for roughly the last 50 years! I started to clean out the inner whorls on the Acanthoceratites but that will take quite a while. There was a third ammonite that was labeled as another Triassic species, but when I got home I recognized that it is actually a Placenticeras, a Late Cretaceous genus. I am not sure of the species and the preservation is different from the North American sites I know about, so I suspect it might be from a European source. I'll post more photos in the Fossil ID thread to see if anyone recognizes it. I also scored a trilobite I've wanted forever, an Elliposocephalus hoffi. Not because it is especially pretty, but because it is representative of the Chechosolakian Cambrian that is so important in trilobite lore. I also grabbed a nice Calymene celebra. Last up for now is an OK shrimp from Lebanon. The body is all authentic, but I'm not 100% sure about the appendages. It's pretty nice though so I like it. There are a few other little things but the above is enough for now. When I got home a box of New Mexico ammonites from the Christmas auction was waiting for me, which made a good day even better!

Private collector mistakes fossil for pterosaur skull. Paleontologists determine it is lung fossil of a potentially 5 meter long coelocanth! https://phys.org/news/2021-02-enormous-ancient-fish-fossil-pterodactyl.html

This fossil was inherited so unfortunatly I don't know the background on it. The creature within is approximatly three inches in length. It appears to have skin like an alligator with the tail of a fish, most resembling a coelocanth tail. My interest in the fossil was renewed after reading about the discovery of tiktaalik. Unlike other supposedly pre-tetrapod fishes, there is no sign of any anterior fins (besides caudal) or appendages. This has given pause to some professional paleontologists who will not even hazzard a guess as to whether what I have is, as I believe, even a vertibrate. (I can't help but wonder if it may be some sort of transitional species, possibly even one with growth stages likened to a modern amphibian.) The previous owner of this fossil was a long-time resident of Corpus Christi, Texas. He also once lived near Fayetteville Arkansas. My suspicion is that the fossil is from the Nueces River Basin. GoodLuck.
