oscarinelpiedras posted a topic in Fossil IDHi group! What is your opinion? I bring you this rarity, which seems to be divided into segments, something I had never seen around here until now in my Carboniferous area. It reminds me slightly of an arthropod, maybe it could even resemble an arachnid. Or maybe they are just plant remains! Note that there are some sort of indentations in some of the fossil segments and there is an area (vaguely reminiscent of an abdomen) that is oval. It comes from the Upper Carboniferous Estephanian B (Saberien) of León, Spain. Alethopteris zeilleri

Mazon Creek Best Of The Best Geralinara Carbonaria Scudder, 1884
RCFossils posted a topic in Member CollectionsThis is a creature that many collectors are not even aware exists in the Mazon Creek Deposit. This unusual animal is commonly known as a whip scorpion. While it is an arachnid and resembles a scorpion , it belongs to a district order called Uropygids. Whip scorpion are incredibly rare in the fossil record. A handful have been described with the earliest known specimens dating back to the Devonian. Any arachnids in the Mazon Creek deposits are considered a rarity. In a faunal study that I referenced in an earlier post, out of 230,000 concretions collected at Pit 11, nine arachnid
I found this in South Yorkshire, UK today in the coal measures (upper Carboniferous). I suspect it may be an arachnid though I am not sure. Please can anyone confirm if it is or isn’t an arachnid? Plant fossils are abundant at the site where this was found. Thanks, Daniel
I found this in West Yorkshire, UK recently in coal mining waste from the Pennine Lower Coal Measures formation (Westphalian A, upper Carboniferous). On the rock, there are several plant fossils such as Neuropteris leaves, but also this fossil. I am unsure whether this is the abdomen of an arachnid or insect, or just a plant fossil. On one part of the fossil, there is what seems to be a faint imprint of a Neuropteris leaf. However, this imprint seems to be from a different fossil which formed on top of the possible arachnid/insect. Do you think this is indeed an arachnid/insect fossil
Florissant spider id ?
LiasEpsilon posted a topic in Fossil IDAll, My son found this orb-weaver spider at the Florissant Fossil Quarry in Colorado last month. It's about 1.5" (4cm) between the tips of the longest legs. There are short thorns on the abdomen, and possibly on the bases of the legs as well. Overall, it's very much like the golden orb-weavers whose webs I have the occasional misfortune of walking into in my garden. Can anybody tell me what genus, or perhaps even species this may be?
