Visiting the Osha Canyon Formation in the Jemez Mountains, New Mexico. Upper part of the formation. The massive sandstone is the Sandia Formation. Underneath is the Pennsylvanian Osha Canyon Formation. FInds: Crinoid stem segments, a rugose coral, a couple of echinoderm plates, and a worm burrow cast. Whole bed of brachiopods: Composita brachiopods? I was shown this site by a semi-professional geologist who calls it The Nursery because there are huge numbers of unusually small brachiopods. Spirifers? some are silicified

Hello everyone, thanks for letting me join the site! I'm an amateur fossil hunter from Toronto who has made a few expeditions in the past months. I've found a few fossils of interest that I'd like some help identifying. Below are links to photos of the fossils in question on my iNaturalist page, along with some additional details. Thanks all in advance! The following were all found along the Don River in Toronto. 1. https://www.inaturalist.org/observations/68570190 2. https://www.inaturalist.org/observations/68573964 3. https://www.inaturalist.org/observations/68570193 4. https://www.inaturalist.org/observations/68300323 5. https://www.inaturalist.org/observations/68573819 This was also found in Toronto, in a clean fill pile. A nice assortment of small invertebrates here. 6. https://www.inaturalist.org/observations/19866874 This one is a real mystery. Also from Toronto, among clean fill. A bone fragment? A piece of vegetation? Coral? 7. https://www.inaturalist.org/observations/68299911 These three were found today in Prince Edward County... 8. https://www.inaturalist.org/observations/69519088 9. https://www.inaturalist.org/observations/69532565 10. https://www.inaturalist.org/observations/69519075#activity_identification_0484c99a-6655-4e0f-8a1c-2ab2cd4c0fea And finally, this Trilobite fragment was found in the vicinity of Arkona. 11. https://www.inaturalist.org/observations/68299694

I have lived on this property in Lawrenceburg, Tennessee for over 35 years. I have been noticing these fossils while working in a shade garden on the property. I believe they are some form of fossilized coral. I tried to find help in the Audubon Society Field Guide and by searching on line, but did not find anything that completely matched my samples. I have selected several pieces that I hope my help identify the fossils. The pieces I have found are usually 1-1 1/2" inches in diameter, and somewhat spherical. Many of the colonies are shaped like a 5 pointed star and appear in somewhat parallel rows. I have found only one example that has geodized. Please excuse my ignorance that prevents me from entering a more specific description. I hope the photographs will help.

Taking advantage of my time spent home, I finally got a couple of glass display cases to showcase fossil specimens from my collection. Finding ones that were affordable and blended with the style of our home, was challenge, and I took my time choosing. Despite a bit of criticism I receive from some of my fossil collecting friends, I am a generalist collector who doesn't specialize in anything. Having said that, my collection does feature some rare faunas; Devonian and Cretaceous bivalves, Lower and Middle Devonian brachiopods and gastropods, Cretaceous vertebrates, etc. The focus is largely on fossils of the Northeast (New York, New Jersey, Pennsylvania, Connecticut, Maryland, and Eastern Canada), but a number of trips to the Ohio Valley, Texas, out west, and Germany have expanded my collection which is about 90% self collected with remaining fossils primarily gifts from generous friends. There is only one purchased fossil in the display and one I traded for. I ended up with twelves shelves- ten devoted to animal life (seven of those are invertebrates), and two for plants. I was seeking to emulate the old style of specimen display that one might encounter in a 19th century museum, when displaying specimens was the priority. I didn't and couldn't display my entire collection which is too large, so I picked representative specimens to tell the story of the vast variety of prehistoric life on earth. Some of my best specimens didn't make it into the display. These are the cases which are situated in our finished basement:

I propose to show us your Cenozoic corals. It is not necessary that it are identified although it would be better. What is necessary is that it are dated. Ok? Come on, I'll start. Cyathoseris castroi (Mallada, 1887) Lutetian South Pyrenean basin

I found this in a sand pit near Kalkaska Michigan as a kid. It was in the vally wall around lake Skegamog. Next to it were a number of sand stones containing shell fossils. I don't know if it matters, but the pit wall I dug into was about 75 feet below the undisturbed grade. The stone I believe to be a sponge is approximately nine inches tall and weighs approximately 9.5 pounds. The chamber's are not uniform in size so I doubt it's being coral. The fact that there were no igneous rocks present makes me doubt pumice. I apologize that I could put up more pictures and close ups, but there was a limit on the upload size.

Hi Everyone, I took a 2 week trip to the Ohio Valley, arriving back in New York about a week ago. It was primarily a family visit since many of my relatives now reside in the Elizabethtown, KY area. However, the Ohio Valley, as some of you know, is very rich in Paleozoic fossils and I just had to make a few stops on my way there and back as well as between family engagements. I will try to share enough to give you all a gist of it: It was a long day's drive from the northern suburbs of New York City to Richmond, Indiana where I spent the first night. The next day I was headed down State Road 101 to Garr Hill, to collect in the Upper Ordovician Liberty Formation. It was my first time at the site and everything I found was collected from loose rocks at or near the base of the outcrop. A couple of pictures:

From the album: Lower Devonian Helderberg Group in Eastern NY
Enterolasma strictum rugose corals from the Lower Devonian Kalkberg formation. Collected 5/31/20 Rickard Hill Rd. Schoharie, NY -
Spring of 2020 We took advantage of the time off and the break in weather to hunt one of our favorite streams here in Western New York. This was just a spring scouting mission to see what was exposed after the ice and snow has melted. Some of the more interesting finds were a crinoid crown (very rare for this locality) possibly Logocrinus, Spinocyrtia granulosa open with both valves, Orthospirifer marcyi, a large Megastrophia concava cleaned by nature with epibionts, and 3 small nearly complete Greenops. We also found many small Favosites coral colonies, large Heliophyllum corals, and 8 different species of brachiopods. Happy Collecting!

Reef-building coral exhibiting 'disaster traits' akin to the last major extinction event
msantix posted a topic in Fossil News
A new study shows that stony corals, which provide food and shelter for almost a quarter of all ocean species, are preparing for a major extinction event. Researchers identified an increased prevalence of certain traits found with previous extinction-survival characteristics among corals. By studying the fossil record of coral skeletons, they were able to determine that corals are showing some survival traits that match the last major extinction event 66mya. These traits include an increase in deep water residence, cosmopolitan distributions, smaller colonies, non-symbiotic relationship to algae and higher resistance to bleaching. The study also discusses in detail the comparison to primates and discusses how primates don't show the same survival characteristics that some corals do. Finally the authors state that the corals that are likely to survive extinction are less likely to be from tropical coral reefs and more likely to be from smaller, solitary, slower growing & deep dwelling corals. https://www.sciencedaily.com/releases/2020/03/200303113246.htm Gal Dishon, Michal Grossowicz, Michael Krom, Gilad Guy, David F.

Coral hunting in the Weißenegg-formation, Styria, Austria (Langhian/Badenian, Miocene) – 10/17/2019
FranzBernhard posted a topic in Fossil Hunting Trips
Hello! Finally, I have some time to post this fossil hunting trip from a warm and sunny day in October, 2019. Introduction The Miocene Styrian basin in Austria is mostly filled with various clastic sediments, e.g. fossil-rich “Florianer Schichten” around St. Josef. The “Mittelsteirische Schwelle”, a north-south trending high-zone of palaeozoic, slightly metamorphic rocks, however, is, in a very literal sense, the base of various biogenic carbonate rocks (“Leithakalk”). The individual carbonate bodies are of slightly different age – spanning the whole Badenian (about three Million years) - and composition. The younger ones to the north around Wildon are characterized by coralline algae and often oncoidic limestones, corals are extremely rare there. To the south, corals became locally an important part of the limestones, besides the coralline algae. No really big coral reef structures have developed, though; coral carpets and small coral batch reefs are characteristic. Various maps from the internet and literature of the visited area. 1 = Kittenberg; 2 = Hötzlweg Depositional scheme of the Weißenegg-formation around the “Mittelsteirische Schwelle”. Within the green rectangle the area of interest. Relief map of the area north of Heimschuh. Note the many very small to medium-sized quarries. Some cliffs are also visible. These corals are witness of tropical to subtropical temperatures in this area about 15 Million years ago. Coral development is considered to depend on local factors like sediment input or (non-)exposure to severe wave action during storms. Coral diversity is relatively high, with at least a dozen of genera described or mentioned. About four years ago, I have prospected the area north of Heimschuh several times for corals. My goal was to find some good coral sites. Fossils in the wild are not super-abundant in this formation, but I succeeded to find a few good spots. Corals are by far the most abundant fossil group, bivalves etc. are much rarer. (Note: there is a very large, active quarry for portland cement fabrication in Retznei nearby, that is famous for all kind of marine stuff, incl. Meg teeth and other large vertebrates.) I will present two sites that I have visited again at 10/17/2019, but already also four years ago. One is at Kittenberg in the woods (1), the other one is a small outcrop along a minor road called “Hötzlweg” (2). Continued...

I bought a new old cabinet last winter and spent several months filling it with newly labeled specimens, most of them now stored in jewelry boxes. I took photos of it to show Tim, Fossildude19 and he suggested I post them in the Members Collections section. I followed his suggestion. The collection started in 2011 with a few fossil purchases off a well known public auction site. By the early spring of 2012 I was collecting in the field and the vast majority of my collection was self collected in that manner from sites, primarily in the Northeast and Ohio Valley as well as ones collected on trips to Texas, Germany and out west. There are also some gift specimens that I own thanks to the generosity of a number of friends, most of whom are on the Forum. The top of the cabinet is occupied by miscellaneous specimens, some that wouldn't fit in the drawers, some slated to be in a glass display case I hope to eventually get, and my collection of fossils found in New Jersey just above the Iridium Layer.

Today I was pretty stressed out, but it was also my day off work so I figured what better to do than go out for a hike. Usually around this time of the year Truman Lake's water level drops, and more spots are accessible to hunt for treasures or to journey and site see. I wasn't looking for fossils but instead I was looking for fishing lures, (You'd be amazed how many you can find when the water drops) but I always keep an eye out for fossils as well. I ended up finding a nice little exposure that is usually underwater, and boy it was worth the search. It was about a hour and a half walk to where the exposure was from my car, and I didnt have long to search before the sun set. I probably had a good 40 minutes of sunlight to search and came up with a lot. So much infact, I still have a lot of cleaning to do! Some of the solitary and colonial rugose corals are geodized, or have lovely crystal lining on the inside. I didnt get to take many pictures which I regret, and my few pictures don't do the lovely crystalized coral justice. I suppose I'll share a final photo when I get everything cleaned up.

Fossil hunting in St. Bartholomä, Styria, Austria, July-September 2019. A Summary
FranzBernhard posted a topic in Fossil Hunting Trips
Hello, I have summarized my hunting trips to St. Bartholomä from July 2019 to September 2019. Its in German and located at an external site: Rudists St. Bartholomä - July-Sept 2019 (external site) (pdf, ca. 4.2 MB) Fell free to delete this post if you find it inappropriate. Thanks! Franz Bernhard -
Hello there! I was inspired by @markjw to check out the Credit River here in Mississauga, Ontario (Georgian Bay Formation, Upper Ordovician) because where I normally hunt there are typically no corals and I'd love to add a couple to my collection. Consequently, I went out for about an hour this morning before the family got up in order to try my luck, and I'm happy to say that I was successful!!! Based on information provided by @FossilDAWG in other threads here on TFF, I think all of my colonial rugose corals are Favistina calcina - here are photos of three of my specimens: Specimen #1 - side view: Specimen #2 - top and bottom views: Specimen #3 - top and bottom views: more to come...

I visited Etobicoke Creek, and, as usual, the place was packed with fossils. Then I went to Credit River...a park near "The Riverwood Conservancy". At first I was disappointed, but in one place I found 3 little corals that had been packed into a mud path by hiker's boots. Here they are; all approximately 4 cm across.

July 23,2019 Its been so hot working outside all week that today's fossil hunt in 70 degree temps felt cool. It was quiet in the stream (besides the sound of wildlife) when I got there in the AM and stayed that way all day. I didnt want to disturb the scene with me pounding on rocks so I surface collected and covered a large area of the stream. Along the sides of the stream are glacial erratic boulders, stones, and gravel. The tabulate corals (Chonostegites clappi, Favosites winchelli, Favosites sp.) I pictured in this post were found among these glacial rocks. In one gully off the stream I noticed a large boulder of Waterlime. I have found parts of Eurypterids in these displaced Silurian rocks before. Today I found a partial Eurypterid on one of these boulders but had to leave it where I found it. Too big and way too far to haul back. Happy Collecting, Mikeymig

Hi! Here is a trip report on visiting a locality near Carlin, Nevada (one of our early videos). I'm not sure if what we decided to call "octopus beaks" (see 1:44 and image attached) are the real thing and not just fragments of brachiopods. Perhaps, somebody more knowledgeable can weigh in with the right answer. Thanks in advance!

Hi guys so I have this Hebertella occidentalis specimen I collected yesterday from the Credit River at Streetsville, Mississauga, Ontario, which belongs to the Upper Member of the Georgian Bay Formation. Do these look like predation marks? There are also what appears to some crystallized grains inside these marks and I think they could be some sort of calcite. Sorry for the noisy grain of the image, but I hope this will help.
