    Trigonotarbid abdomen?

    Hello all! I just recently purchased this specimen which was indicated to be from the Carboniferous, Bashkirian-Westphalian B, beds of Poland, dated to be Pennsylvanian at 314 mya. It was sold to me as a Trigonotarbid abdomen. The white square is 1 x 1 cm for scale. While I am no expert on arachnid orders, it appears to be lacking the segmented plates that surround the perimeter of the inner abdomen. Could this be part of some other segmented terrestrial arthropod, or could this feature be covered up by surrounded rock or have been damaged? I will be posting pictures of the specimen below, please let me know if you have any questions or need further information to support a conclusive ID. Excited to hear y'alls input!

    Fossils show giant spiders

    Fossils show giant spiders have been creeping around Australia for 16 million years (msn.com) Amazing fossil, are these real fossil color ?
  4. L.S., It has been almost four years since I found an unidentified arachnid fossil in the Westphalian D (Late Carboniferous) of the Piesberg quarry near Osnabrück, Germany. The little critter received a warm welcome here on TFF, being awarded the July 2019 IPFOTM and later even given the honour of 2019 IPFOTY. At the time, I was happy to announce that the specimen had gone to dr. Jason Dunlop of the Museum für Naturkunde in Berlin (an expert on fossil arachnids) for further study. Today, I'm thrilled to give another update! Yesterday, the detailed study by dr. Dunlop culminated in a really nice open-access publication in PalZ, which can be downloaded HERE. The Piesberg-fossil turns out to be a new species and the first "true spider" from the Palaeozoic of Germany (so a spider from the order Araneae as opposed to early spider-lookalike arachnid groups such as the trigonotarbids or phalangiotarbids). The fossil (now a holotype) has been donated to the Museum für Naturkunde, where it is conserved under repository number MB.A. 4298. This has been a great experience, as I learned a great deal about arachnids and spiders and spinnerets along the way. Hope you'll enjoy reading dr. Dunlop's paper as much as I did! Kind regards, Tim Reconstruction of Arthrolycosa wolterbeeki Dunlop 2023 Reference: Dunlop, J.A. (2023) The first Palaeozoic spider (Arachnida: Araneae) from Germany, PalZ, published online 16 July 2023, https://doi.org/10.1007/s12542-023-00657-7

    Spider in Baltic amber

    Maybe the title should be "What's left of a spider in Baltic amber". Just got a small 50g package of Baltic amber & when I went to rinse it off (usually a little dirty) I found one rippled piece that was fairly clear so I checked it with my loupe. Found this tiny spider (about 2 mm in size) just below the surface in a lower part of a ripple. I added a small amount of sunflower oil to aid in taking the pic due to the slight distortion caused by the ripple. Not a whole lot left of the thing. I'm thinking it was dead prior to getting "resonated", but it had some hairy legs. Not really holding out any hope that it can be identified as anything other than a dead spider, but I thought I'd share it anyway. Taken with my Dino-lite at 185x.

    Mazon Creek Spider

    This concretion opened up a couple weeks ago. When I first looked at it, I could tell there was something there, but the contrast between it and the surrounding matrix was very low, so I didn't think much of it. I got around to looking at it again yesterday. In very bright oblique light, I realized it was actually a very beautiful spider with legs and all. It measures about 1cm. I am not sure on the ID. Colors inverted
  7. Hey everyone! I was wondering about 2 Amber specimens with inclusions that I've had for a while now. I tested both in salt water and acetone and both passed (Both Float in the salt water and both were not affected by the acetone) but I wanted to know what you think. I'll include close ups, regular and under UV light photos of both.

    Two specimens.

    From the album: Burmese Amber

    Top specimen contains a small lizard foot. Bottom specimen contains what appear to be two spiders. Bought from Israeli seller.
  14. Hi, I found this the other day and thought possible it was a crinoid but the bottom was very round and not disc like. Any help would be greatly appreciated. It was found in the Canehill, Arkansas area Northwest Arkansas, thanks.
  15. Hey guys! I found this nice looking Columbian Amber with a lot of inclusions and a big Spider, and was wondering what you think about it. Let me know what you think!

    Diatomite fossils

    On October 10, we (my wife and I) went to an extraction site for diatomites, in the Cantal massif. The age of these rocks is Messinian, bordering on Miocene-Pliocene. I present some photos of the exploited site (seen during a previous visit) and some fossils found this Sunday in the rocks stored awaiting industrial treatment. The remains of fossil plants are not abundant, you have to cut a lot of rock and the quality of conservation is often poor, but occasionally a pretty leaf appears... The next problem is long-term preservation, even with immediate consolidation treatment, performed at the site. The most 'common' species is Alnus hoernesi = A. stenophylla, but studies conducted for over a century have identified 86 species!
  17. Hi everyone, this is a piece of "amber" I bought a little while back. Not entirely sure if it's real so I thought I'd check here. It fluoresces green under a UV light and sort of smells sappy when pricked with a hot pin. Also included are some microscopic photos of the insect inclusions.

    Any chance this is a spider?

    Itsy Bitsy spider..

    At least I think it's a spider. Only has 6 legs. Only 1.5 mm in length from highest tip to lowest leg bend. Burmite amber, 99 myo (give or take). Pic at 90 x
  20. Hello my friends ! I just wanted do share pics of superb. male Jumping Spider ( Salticidae ) that i had. It is not often to see so amazing, colorful and well preserved eyes of jumpers so a little showing off I will upload more photos in comments. Cheers from Poland !
  21. Hello from Greece. Nice to meet you again. Before 2 days in a new open road from Greece to Bulgaria i stop at one point along the route to look if i found any interesting rocks or fossils. (the point is in the photo). I found obsidian, corneal and more, BUT in 7 meters deep down, from the top I saw a small rock protrude from the base rock and it made me curious about the strange lines he had. With a screwdriver I pulled it out relatively easily as the rock is not too hard. My big surprise was when I held it in my hands. It was very tough but very lightweight and is hollow and has something inside him. For sure it is not rock and to say it fossil I know it will be crazy. But it is there in 7 meters deep inside the rock . I didn't wash it, I didn't clean it at all. It's like I got it out of the rock. I've been searching the web for two days to find out what it is. I came to the conclusion that the most likely is that it is an insect cocoon with the insect still in it. An yes i know is crazy . I would like to ask you to help me with that. I take some good photos but i know from photos is not easy to identify what is. I am sure. When everything calm down from coronovirus i would go to Athens for examinations. The dimension is 10 x 5.5 x 2.5 cm So thanks everyone for any help....
  22. This is the most incredible piece of amber ever found. its so unbelievable, that nobody takes me serious when i post images of it anywhere. Facebook groups delete it and block me for posting fake fossils. its still attached to about a foot and a half of the original tree that the sap was secreted from. that in itself is very rare and one of a kind. this part that is wood, has high magnetic attraction. the fact that its included with creatures that have never been identified before, neither in amber or out is another unbelievable aspect of this piece. notice the two creatures in blue. both were stuck on the outer most layer of the sap. with only a very thin layer of amber covering their bodies. notice how high above the surface of the amber this dinosaur looking creature got stuck. then, look at the detail of its face... the two images in blue were taken under UV light. this piece was found in north baja mexico. all of the images of creatures oin this post can be found inside this one piece of amber. nothing has been altered or added, only the one photo of the turtle has the red filtered out so that the image of the turtle can be singled out. where can i take this to get documentation authenticating that its real??? open each image to see the complete images. also if your skeptical about the inclusions or the authenticity of this peace, pm me so i can send you a video of the turtle trapped in the middle of this thick chunk of amber. thanks. shawn
  23. 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
  24. How do these pieces of amber look? The first few pictures of the flies and the feather are described as deinonychus or velociraptor (or something like this as the description was not clear) from Burma. The last few are of a spider.
