Good morning all! Hope everyone is healthy and starting to get back to normal, whatever that will be! Found this yesterday below a roadcut in Kansas City laying by itself. The shape instantly caught my attention, and when I looked at it, I believe it is a totally encrusted large bivalve/clam! Very similar to the large native freshwater clams we have around here. The encrusted material is limestone- there are crinoid parts/what appears to be sea urchin spines and "hash". You can see faintly concentric lines. So my questions are-Since it has the shape and appearance of a bivalve, but is totally covered by "matrix" is it a concretion, or simply an encrusted shell? Second-it's very cool in itself, but do I try to clean it up to see what species and have a cooler shell? Could it even be cleaned well enough? Just alternating baths/soaks in vinegar?I have also included a pic of the encrusted matrix. Thoughts all? Thanks! Bone
I am studying a tiny area of a fossiliferous limestone rock from our yard and trying to determine the different items in it. The fan shaped item in the lower left corner didn't really look like the fenestella bryozoa that I am used to seeing, so I did a bit of research. I found a page with a similar image and was wondering if I am correct (or even close) in identifying that particular item as a cheilostome? Here is the page I was looking at: https://www.researchgate.net/figure/A-sample-of-bryozoa-sand-sample-number-71-from-a-depth-of-130-m-on-the-Lacepede-Shelf_fig1_238417060. Would the fenestella bryozoa be seen next to the cheilostomes? And what about the little flower like item that is above and to the right of the fan shaped item? It's kind of hard to see - I can circle it if needed. This area covered by this image is approximately 2cm across. That is what caught my eye - how tiny the fan shaped item was. This rock is from Huntsville, AL. Thanks guys and gals!!
Ok This and many more I found on "Paniotis formation" in Limassol lets call it that, coz I can't find it on the maps, but after cross referencing from 3 geological maps it is supposed to be Miocene territory. As i mentioned before that formation is a small oval shaped hill 3-4-5km from the sea, 3x6km on top with steep edges, about 100m tall. And at some point I found some sedimentary formations moving in nicely shaped curves and after that huge formations full of shells corals sponges maybe some fish, plants who knows..Those formations are 4m high above ground but i am guessing they go well bellow as well and 100m2 or more or less. I ll take my camera and get u some photos on site better. But I picked a few stuff and here u go 1)this shell,(or inner cast, but I think not) bright orange, yellow, black and beige colors on its upper surface, as many shapes on those formations. 2)this one shell with a different finish on one side 3) a mollusk cast, I believe it belonged to a species like the one next to it. The actual mollusk on the right I found on the beach I think, so I has to be a modern one. But the cast is from that formation area 4) 3mm diameter 5mm length tube shaped, composed by many linear crystals of brown and beige colors. 5) coral or plant or something else?
