Hi all, I have been seeking an isopod fossil for a while. I came across these unidentified Cretaceous marine fossils from Lebanon I know the isopod, Cirolana garassinoi, has been found in that region but these look nothing like that species. Could this be a yet-unidentified isopod?

I have been revisiting some of my fossils from my collection I gathered during a two year period where I had the privilege of exclusively exploring hundreds of acres of land in NW Arkansas in and around the town of Eureka Springs. During that time, I was able to collect on friends private land that had never before been surveyed by the outside world. 99.99% of what I came across was of oceanic and inland sea origin when it came to fossils but a couple of fossils perplexed me and this is one of them. I came across this fossil, or pseudo fossil, or weird anomalous permineralized erosion, or “I have no idea,” in a Mississippian Deposit known as the St. Joe and Boone Formations. I found this early in my collecting and had little background or research study under my belt at the time of discovery. I thought it was interesting and set it aside and moved on. I know that the area it comes from isn't known for bone, but it really does appear to be permineralized shoulder bone and upon magnification it has the hallmark of having been biological in origin, but I AM NO EXPERT, and I don't like to give into to fantastical thinking especially when there isn't other supportive evidence to suggest that Arkansas has fossil bones of any kind. What else could it be? Under magnification the flip side of the fossilized bone shape has detailed scale or skin pores and textures that have been preserved through the amazing process of permineralization…but again, there could always be a more plausible explanation that is outside my own understanding, simply because Arkansas doesn’t have bone fossils, historically speaking, aside from the Arkansaurus toe bone that was found some 160 miles south of where this fossil was found. I bring this to the forum because I would love to be able to get feedback and answers. And for future notation, I have many more fossils to present to the group and am looking forward to all of your thoughts, suggestions, expertise, and recommendations! Sincerely, PESEBECHE

This fossil was found yesterday on Murdock Beach, Olympic Peninsula, Washington. It is about 1" x 2". We've been there many times but never found anything like this before. Actually, my kids found many fossils that weren't typical of what we 'usually' find. Any help with identifying it would be much appreciated. Thank you.

This fossil was found in Petoskey, Michigan at a beach I'd rather not identify while I was looking for petoskey stones with my family, it caught my eye as looking like a shell of some kind. Since I couldn't come to a conclusion as to what it was I consulted a michigan based rockhounding youtuber who advised me to post here. I cannot, for the life of me, come to a conclusion on what it is with any certainty, please help.

I need help identifying these sauropod teeth from Yixian Formation
-Andy- posted a topic in Fossil ID
Hi all, I have several sauropod teeth from the Yixian Formation of Liaoning that I need help identifying. This is Tooth 1 - White Length: 44 mm Formation: Jianshangou Beds of Yixian Formation Locality: Chaomidianzi, Sihetun, Beipiao, Liaoning Province I believe this is a Dongbeititan dongi tooth as this tooth has the morphology of titanosauriform teeth, and Dongbeititan is the only titanosauriform from that locality as far as I know. The formation is based off the locality of Chaomidianzi (my source was confident of that locality) --- This is Tooth 2 - Red Formation: Lujiatun Bed of Yixian Formation Locality: Yanzigou, Shangyuan, Beipiao, Liaoning I believe this is a cf. Euhelops sp. tooth as this tooth has the morphology of titanosauriform teeth, and cf. Euhelops sp. is the only titanosauriform from that locality as far as I know. The formation is based off the locality of Yanzigou and the red matrix. I've compared this matrix to multiple Yanzigou locality fossils of the Lujiatun Beds and they are identical My ID is based off this paper "Basal titanosauriform (Dinosauria, Sauropoda) teeth from the Lower Cretaceous Yixian Formation of Liaoning Province, China" --- This is Tooth 3 - Partial Formation: Lujiatun Bed of Yixian Formation Locality: Yanzigou, Shangyuan, Beipiao, Liaoning I believe this is a cf. Euhelops sp. tooth as this tooth has the morphology of titanosauriform teeth, and cf. Euhelops sp. is the only titanosauriform from that locality as far as I know. The formation and locality is based off the red matrix in the cross section. This tooth was resold from my source but he confirms it's definitely within Beipiao and either from Yanzigou or Sihetun. I've compared this matrix to multiple Yanzigou locality fossils of the Lujiatun Beds and they are identical --- This is Tooth 4 - Tiny Formation: Yixian Formation Locality: Sihetun, Beipiao, Liaoning This is the toughest tooth of all due to its size and incompleteness. It's the top half of a spoon-shaped crown. Again, the source admits being a reseller but he promises the locality is accurate. I believe this is a Titanosauriform indet. I showed this tooth to @hxmendoza and he agrees it's a tooth, not a claw. The closest match I can find to this tooth is MSNM V6214 from "Sauropod teeth from the Middle Jurassic of Madagascar, and the oldest record of Titanosauriformes" May I have your thoughts on these IDs please? Thank you.-

Good morning! I was hiking along a park path when I inspected a large boulder and found these two fossils, the first of which is similar to modern day scallop. I didn't have anything to measure with -my apologies, but it was approximately 1 1/4" in height and 1" across. the other object has some faint lines/rays emanating from ~9:00 to 2:00, but not sure it is overlying the underside of another shell, or is part of the fossil. This one is approximately 1 1/2" x 3/4 " Any thoughts and suggestions on i.d.s welcome and encouraged!..... not sure I could remove the scallop intact but thoughts on how to do that as well? Bone

Hi all, I recently got this crab as a gift from a Burmese friend. He said it came from the Rakhine State, western shore of Myanmar. He said his friend found it there. Unfortunately, neither of them kept any extra provenance detail about it. I can find no info whatsoever about this crab online. I don't think Myanmar fossils outside of amber have easily accessible documentation. This crab looks like it might be a Galene bispinosa. Does anyone know what species it is, and what age or formation it possibly came from? Thank you.

Hi all, I have fossils from Singapore's Jurong Formation, aged from late Triassic to early Jurassic (235 - 175 mya). Some were found over 10 years ago by a fossil-digger while others were dug up recently by the two of us. Several specimens have been handed over to our local museum. However, no one really knows what family or genus these bivalves belong to. I was hoping you guys could help. Specimen 0A Specimen 0B Specimen 0B alt view Specimen 0B alt view
