Hi all! Today I'll show you a site which is quite similar to the subject of the Frozen Fossils topic, but somewhat opposite of the latter, as it's only accessible in summer (end of July- beginning of September). It's situated in the historical city of Vladimir on the Klyazma river. The banks are overgrown with vegetation, no movement whatsoever on the river and very few people visible. Occasional ducks and herons, fish splashing nearby.The bridge is the only reminder of civilization. The river bed is surprisingly formed of solid clay you can confidently walk on. The age of this clay is Lower Kimmeridgian (mostly the 1st bauhini/baylei zone which is pretty rare in European Russia)

I’m struggling to identify this. The closest I’ve found is possibly a fossilized crayfish gastrolith. But I could be way off. I’m very new to fossil ID. I do find a lot of marine life fossils in my area. I had thought perhaps brachiopod, but it looks nothing like my other one. I’ve included a photo of the unidentified piece along side my brachiopod so if I have misidentified it please correct me. Thanks in advance. Details: Northeast Arkansas Mississippi Alluvial plain Along the Eastern edge of Crowley’s Ridge I’m 93% certain the material is quartz (chert)

Initially described as a fossil spider, this fossil ends up being a crayfish from China https://m.phys.org/news/2019-12-jackalope-ancient-spider-fossil-deemed.html

Below is an example of how weird and rapid evolution can be. I have to wonder how often this has happened in the past and how invisible it would beto a paleontologist with nothing but hard parts as fossils and the lack of temporal resolution in the geologic record.

Is this what it looks like? ..... a crayfish? found in gravel drive west of Houston texas gravel from Brazos River. and from the looks of the shape of the stone there could be more lurking inside....sorry about photo quality will take more with good camera later am having a problem getting the photos to upload from camera.

As I was putting together labels with photos containing microscopic images of inclusions in coprolites, I came across something that I may have misidentified as a fish tail and vertebrae in a very small coprolite. After looking at it again, the tail looks more like a shrimp or crawfish tail than that of a fish. What I thought were fish vertebrae, look more like crustacean arm joints/elements. Can anyone please confirm this for me? Thanks a bunch! Formation: Oxford Clay (Jurassic - Callovian) Location: Orton Pit, near Peterborough, Cambridgeshire, England

This past weekend my wife and I, a few friends and a few other fossil hunting fanatics braved the sweltering heat and humidity that is eastern NC summer. Forecast was for temps in the low - mid 90s F, high humidity and 50-70% chance of showers and thunderstorms. This was our 3rd attempt at accessing a Cretaceous deposit along one of the rivers after 2 unsuccessful attempts earlier this spring due to high water. With many of the eastern NC rivers running higher than normal so far this summer, we wanted to take advantage of a lull on this particular river, since there is no guarantee a tropical storm/system won't flood us out for an extended time period at any point from now through late fall. Even though we knew we were going to be hot and sweaty, harassed by mosquitoes, biting flies & gnats as well as the possible snake or 2, we had to take what low water we could get. We were all drenched in sweat (and sand / mud) the entire 2 days we hunted. Coming along on its inaugural fossil hunting trip was a new photo scale cube custom made by Ray/ @aerogrower for Mrs. SA2, in pink. She was quite surprised when a box addressed to her showed up a few days before the trip and it contained her very own cube, in pink. When I explained that its a 1 of a kind, she was even more excited. Even more importantly for me, Mrs. SA2's new, pink cube proved to have "the magic" that so many TFF members have come to expect and enjoy in Ray's cubes. Here are a few photos of it beside the massive, almost complete Deinosuchus rugosus vertebrae I found on Sunday morning. These photos were taken right after it was found and given a preliminary rinsing off. Note how nice the cube looks with pink paint. Mrs. SA2 was not impressed with my muddy finger prints on her new cube and promptly cleaned it off before the last photo. It is by far the most complete and largest Deinosuchus vert in our collection. Once I finish cleaning it and the other goodies we found, I will post some more photos. Quite a few teeth and verts of Deinosuchus and other crocodile species were found by the group as well as the normal massive amount of Squalicorax, Scapanohrynchus and Carcharias teeth. Numerous Cretaceous fish teeth and even a few Hadrosaur teeth and 1 theropod tooth were also found over the weekend. What we didn't expect when we made the trip, was for the wildlife to be so determined to keep the fossils away from us. Here is a photo of a big crayfish holding onto a sharks tooth. Determined little thing so we traded him a clean getaway for his tooth. One of our group even snapped this photo along the river bank while she was scanning for fossils. Of course, its all fun and games until you slip on the sloping, wet clay and fall face first at the snake you are attempting to photograph. (YES, that really happened.) More to come......

Found in Guernsey, Wyoming area. Shake rock. About 1 inch long. If you notice, in the rock within the fossil has small line imprints. Assuming a crayfish, but is incomplete. Also on the same chunk of rock, a small (not even a centimeter) fossil that appears to have rings. Possible shell? Rock has tiny fragments of same red fossil scattered on it.
