Hardly anybody ever talks about the Cambrian fossils of the southern midcontinent (USA). They're super-underappreciated. Show us what you've got! Here's one to start us off: Thorax and pygidium of a trilobite, possibly Orygmaspis, typically referred to as "Orygmaspis cf. Orygmaspis llanoensis" but probably a different species altogether. Note the two pairs of macropleural spines marking the final thoracic segments. Davis Formation (late Cambrian: Furongian), south side of Highway 8, St. François County, Missouri.- 3 replies

There have been other microbes freed from ice or salt before, but if these are indeed alive they shatter all records for oldest living things by about 600 million years!!! https://www.sciencealert.com/830-million-year-old-microorganisms-found-trapped-in-australian-rock/amp

PBFossilAgae05.tif Pittsburg Bluff Formation (near Mist, Oregon) Late Eocene or early Miocene. I am finding a lot these tubular items in the matrix. Still waiting from the adapter for my good camera, this is from a 5 mpx camera. Since it is a marine environment, perhaps this is some type of Algae? On my 27" screen the yellow ring part has fuzzy hairs protruding. This was taken with a 5 mpx camera and a 10X objective.

Illusory erect spines(?) on a Kimmswick receptaculitid
pefty posted a topic in General Fossil Discussion
UPDATE: These seem to just be weirdly incomplete cross-sections through ordinary cylindrical meroms. ++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ This weekend in the Kimmswick Limestone in eastern Missouri (Pike County) I saw plenty of receptaculitid algae, mostly of genus Fisherites. But one cross-section has a feature I've never seen before: a fringe of what look like erect spines on the external surface. Can someone point me to a reference for understanding this feature functionally and/or taxonomically? I've looked in the usual places but I d -
Location: n-e Italy. Probably Permian or Carboniferous. It's a fossil? Algae?
-
The fossil was found near the Mukhavets River, Belarus, Brest. Length ~ 6-7cm (~ 2.5 inch) whole piece. If I registered here, I will be impudent: you can recommend a book (100 -200 pages), an introductory course in fossils.

I've got this big hash plate that I collected last year and I somehow didn't notice this thing poking out until now. It looks like an algae to me. Found in SW Wisconsin in the platteville formation.

Hello everyone, I have posted about this fossil before but I was not able to get it Identified. I have decided to create a separate topic for it because I am quite interested in if this is really what I initially thought it was. The fossil is from Eifel (Middle Devonian) and on one side there are a bunch of Crinoids columnals, but upon flipping it over I noticed this darkened branching structure on the rock, to me it looked very reminiscent of certain algae, although I have never seen anything like that from the Devonian so it's probably something else. So my question is:

Hello Dear Friends! This is my first topic on this forum. Hooray! I work in museum and sometimes go on the Kaliningrad beach of Baltic sea and search some fossils. I'am not paleontologist and i need help to definition of them. THe last time i found some algae but i'am not sure. Place was in a few meters from cliff on beach. p.s. can i add my other find in this topic or should create new?

a friend and I traveled to the florida barge canal on Saturday. it is a 4 hour trip for us. besides the usual finds, my friend found this, and we were wondering if it looks like algae to anyone else, besides us. lol. thanks. ( second photo is of my best finds of the day, still needing a final cleanup....also found a 4" sand dollar that broke getting it out of the bank....and a 5" thick, 6' long section of broken sand dollar edges all in hardened stone...ugh. )

Hello everyone, I found the below ichthyosaur vertebra on the beach at Wimereux two weeks ago. It had obviously been lying there for some time, as it was covered in green algae and barnacles. Based on the advise of various friends and the fact this rock seems to hard and massive to work through using just my Dremel, I'll be leaving the fossil in its matrix. However, I do want to clean it up from the algae and barnacles. As such, I used a 1:2 dilution of 14° household cleaning vinegar and a couple of sturdy brushes to remove most of the algae (dipping the br

I have a few specimens that I recently collected from a river. The best are covered in dried algae that needs removal. Does anyone know how to remove the algae?

Anyone seen this species or similar? Found in Pennsylvanian spoil piles of central Illinois (near Peoria). Is it part of some kind of alga? Not my find and not my specimen, so these photos are basically what we have to go on. More broadly, can anyone here recommend a Treatise-style taxonomic book detailing known algal heads / macroalgae in the fossil record? Thanks.

I recently aquired this Glossopteris. It has a green coating which looks like algae. How do I remove this without damaging the fossil ?

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

Hi guys, I would like to know if you can recognize this algae fossil. It is Cenomanian in age and associated with microbialites. My first guess is cyanobacteria. Thanks!

While hiking through a desert area just southwest of Tucson, AZ. I found these interesting layered rocks. Over the course of an afternoon I came across a couple more spots where these types rocks were strewn over relatively large areas. Many of the pieces would fit inside a square inch or the palm of your hand, while many others were a few feet long/wide. I showed these to a local geologist and he called them stromatolithic Paleozoic limestone – evidence the area was once covered by water and these represent the layers of algae, probably in the form of algal matting that existed there, dat

I would highly appreciate your opinion about this formation . Marine , Pliocene or Pleistocene age, Greece . Could be algae , bryozoa ?

Hello all. I picked up this fossil in a Permian formation on the Potash Road, unpaved section, SW of Moab. I think I can eliminate what it is not but am unsure of what it is. I do not think it is some kind of sponge. It does seem to have the structure of coral. It does not it seem to be like any bryozoan clusters I’ve seen. If that is correct, this begins to narrow it to bacterial. The fossil material is very thin overlaying a hard red clay base, so I don’t think it is a stromatolite. It does not come in layers, but seems to be just one layer. The piece is 4cm x 4cm x 4cm. The fingers in the t

I found this in my Seattle area yard, near the dead stump of a small maple. After washing and bleaching the septums appear filled with sand and shell bits. There is also something growing throughout it like a veinous system—likely plant? It is heavy. There are striated and mineralized layers. There is a ventricle feature and a faceted stem—it’s disturbingly brain-like. I feel honored to have finally guessed my way through your captcha (respect!)~~hoping someone can identify this oddity. Best guesses so far are coral or fungus, but I’ve not found any examples sporting this stem canal...

Saw this at a rock shop. Reminds me of lichen. Thoughts?

Hello again. I have several of these strange fossil discs. I cannot find tags for them in the boxes of minerals and fossils recently acquired. Possibly some sort of jellyfish? sea sponge? Any help with ID is of course always appreciated!

I was just going through a handful of Pioche Shale (Early-Middle Cambrian, Nebraska Nevada) trilo plates I bought a while ago, and found this interesting piece. I'm leaning more towards algae than worms, as they are reminiscent of the carbon film preservation of algae from Cambrian formations in China. Any thoughts?

Hello everyone, I had recievrd this as a part of set of many fossils a few years ago as a gif, it was labeled as an algae fossil and the piece is very interesting but I am not sure what it is and what the age could be, one side is very glossy while the other is partially so, the glossy side has very interesting coloration and I am unsure of what it could be a mineral or a part of the fossil, the other side has some staining which could also be the fossil I am really not sure but another very unique thing about this is that y the side of the rock has almost a fiberous look with lines
