    Warmed fossils

    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)
  2. 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)
  3. 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
  4. 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.

  5. 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.
