Synonym: †Archotuba conoidalis Hou et al., 1999, †Cambrorhytium sp. Chen & Zhou, 1997 Quote from ‘The Cambrian Fossils of Chengjiang, China: The Flowering of Early Animal Life, Second Edition’: Hou Xian-Guang et al., p. 136: “This species is relatively common with hundreds of known specimens, which are essentially the remains of the tubes of the animal. 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
