I found this in an abandoned fish nest in a human-made lake. One of my favorite finds!

Found in Paleozoic gravel alongside crinoids, corals, and gastropods. Sorry if this is just wishful thinking! Thanks. The rock is about an inch tall

I drive 8 hours with a friend to a location he remembers from his childhood as yielding a lot. Oh boy it did. 100% worth the drive. Lake Huron, among the agates, pyrite, yooperlite, has some extraordinary Devonian fossils. All fossils were collected from the beach of his family’s property except for the fenestelid bryozoan, which was found at a gas station on the way there. please enjoy this collection of gastropods, petoskey stones, various tabulate corals, crinoids, stromatoporoids, bivalves, Brachiopods, tenteculites, horn corals, an unidentified agatized fossil in jasper matrix

Found in landscaping gravel at a gas station on a 6.5 hour drive to Lake Huron for some fossil hunting. This is probably Devonian. Instinct tells me horn coral but it looks rougher than that and lacks visible septa at the top. Bryozoan colony? That’s my next best guess. Thanks! Love you guys.

Found these at the Nike Missile site in Waukesha Wisconsin. I found a chunk of armored fish bone in the same area. This is an update on my last post with the moss cleared off more. Thanks!

My collection is enriched with new pieces from the dear, old Europe. This is a Gryphaea dilatata, the so-called "devil's toenail", from Villers-sur-Mer in Normandy, France:

All of the specimens are preserved as compressed fossils, in which a whitish color, sometimes with rusty patches. No proboscis or other soft parts of the animal have been discovered. The tube is shaped like an elongated cone. Lar

Help request! I am putting together a tool for judging rock age based on very crude, whole-rock, hand-sample observations of fossil faunas/floras -- the types of observations a child or beginner could successfully make. I view this as a complement to the very fine, species-level identifications commonly employed as index fossils for individual stages, biozones, etc. Attached is what I've got so far, but I can clearly use help with corals, mollusks, plants, vertebrates, ichnofossils, and the post-Paleozoic In the attached file, vibrant orange indicates times in earth history to com- 5 replies

Mazon Creek Best Of The Best Octomedusa Pieckorum Johnson And Richardson, 1968
RCFossils posted a topic in Member Collections
Octomedusa is a type Scyphozoan jellyfish. It is the smallest described species of jellyfish that can be found in the Mazon Creek deposit. The bell can reach a maximum diameter of approximately 2 centimeters. Like all Cnidaria from Mazon Creek, they are only found in the marine portion of the deposit. In the faunal study that I have referenced in previous posts, Octomedusa made up .03% of 230,000 concretions collected. Often times, only the bell is preserved. Well preserved specimens will show 8 tentacles. Depending on orientation in the concretion, some specimens will- 11 replies

I acquired this enigmatic creature a while back and just rediscovered it in storage. It was found in the Heilinpu Fm, Kunming, Yunnan Province, China (Lower Cambrian, same age as the Chengjiang fauna). I have seen a few similar creatures offered from the same locality from a few sellers. It has been alternately labeled as either a cnidarian or ctenophoran. However, I've looked through a few dozen papers about cnidarians/ctenaphorans from Chengjiang and have found no similar specimens. Has anyone seen these before?

This is a new one for me. A neat little button-like horn coral: Dipterophyllum glans from the Middle Mississippian Burlington Fm. of Iowa. Didn't know which forum to share this, so I thought I'd drop it off here for posterity (scale in mm)

Found in Southeast Indiana on the Whitewater River. I find a bunch of Grewingkia but this coral looks different, has a deeper chalice and wider at the top compared to the length. Thanks guys!

On this dreary first day of the New Year, I was poking around in some of the fossils I picked up on the Whitewater River in Franklin County Indiana and trying to id them. The fossil on the right hand side is shaped like a Horn Coral which I find alot but it shares the same crenelated surface as the fossil in the middle which isn't shaped like a Horn Coral. Could the middle fossil be Cystiphylloides? The piece on the left I have no clue, it's really porous and may be just a rock, but I see a small mold of a shell in it? Appreciate you help and want to wish everyone a Happy New Year!!

Dear The Fossil Forum members, I have those Cnidaria (and a few other unidentified Cnidaria genera) from Camadas de Alcobaça Formation, Kimmeridgian, Portugal. I would be interested in Neogene Bivalvia or Gastropoda. If interested drop me a line please. Kind regards, Ricardo

Quotation Wikipedia: "Nemiana simplex has given taxonomists great trouble due to its simple nature. When the species was first discovered it was placed in incertae sedis, however since then, a combination of well-preserved specimens and new techniques that have allowed scientists to examine the creature's body structure, have given the creature anatomical links to jellyfish and was subsequently placed in with the other extinct coelenterates." Nemania simplex is one of the most commonly found Ediacaran organisms. Lit.: Palij, V. M., 1976. Remains of soft-bodied and trace f
