    Favosites?

    I found this Favosites turbinatus today while fossil hunting in Louisville, Kentucky. The problem is it was mixed in with Ordovician age fossils such as Hebertella occidentalis and Platystrophia ponderosa. The area was very eroded and it could have just been jumbled up with the other fossils. Do you think this is what it is?

    Blue agatized tabulate coral!

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

    Conulariid or nothing?

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

    Port Huron, Michigan trip

    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, and a pudding stone I felt like showing off too. Thanks! I highly recommend the area.

    Horn coral or bryozoan colony?

    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.
  15. 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:

    Placosmilia vidali

  17. 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. Large individuals can reach 5cm in length and 6mm in diameter for the wide opening, with a sharply pointed posterior end. The surface of the tube is smooth and and lacks ornamentation, but a few specimens show sparsely distributed annulations. Parts of the intestine can be seen through the tube as a dark longitunal structure running down the midline of the fossil. Archotuba is monospecific. A. elongata was originally reported as Selkirkia? elongata Luo & Hu, 1999. Chengjiang material recorded under the name Cambrorhytium sp. nov. of Chen & Zhou, 1997 and the species Archotuba conoidalis Hou et al., 1999 are considered to be the same species as A. elongata. A. elongata shows similarities to the other Cambrian tube-dwelling genera Selkirkia and Paraselkirkia and phylogenetic position of A. elongata remains problematic. It was originally assigned to Priapulida (Luo et al. 1999; Hou et al. 1999), but others have suggested that it might be related to cnidarians (Chen Jun-yuan & Zhou 1997; Chen Jun-yuan 2004; Huang 2005).” This species is often found fixed to other creatures, and even clustered together with its own kind in similar orientations. A sessile lifestyle would suggest against an assignment to Priapulidae. However, if indeed they were sedentary like the cnidarians, no tentacles have been preserved to support such a conjecture.

  22. 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 commonly observe the item of interest; paler orange indicates times in earth history to less commonly observe the item of interest. White indicates very little to no practical probability of observing the item of interest. Please keep in mind that the listed indicators are things like “conspicuous horn corals,” purposefully declining to address rare encounters with groups of low preservation potential, low recognizability, etc. Got additions/amendments, especially for the groups mentioned above? Toss them in the comments below! Thank you..... https://docs.google.com/spreadsheets/d/1tVm_u6v573V4NACrdebb_1OsBEAz60dS1m4pCTckgyA

    Rugose coral?

    Is this a rugose coral?
  24. 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 show a crenulated edge around the bell. Most specimens show very little raised detail and often appear as just a color difference in the rock. A large “X” shaped mouth opening is preserved in some better specimens. This first specimen shows most of the defining features.

    Possible Chengjiang cnidarian?

    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?
