This past month I was at Latvia and Lithuania for ten nights, investigating their amber industries. Among other specimens, I bought this large polished nodule of transparent Baltic amber, that was reputed to have a "tiny spider" inclusion. I found and photographed a very small arthropod—but since I cannot count body parts and legs, I cannot say it's a spider. The purchase took place in Riga, Latvia; though I was informed that a great deal of available amber comes from Kaliningrad in the former-USSR. Jamey D. Allen - Bead Historian

Just found this juvenile Eurypterid a couple hours ago....went rubble picking today in the Silurian waterlimes. I got very lucky....like 1 in 10 years of searching lucky. Time to get some lottery tickets! All kidding aside....I’m floored....super happy. I’ve been trying to find a nice Eurypterid for years ever since my first hunt in 2010-11. It’s about 1.5 inches. Juvenile for sure. It has walking legs and the swimming paddle on the left side. The right walking legs and paddle could be present but I’m too afraid to touch it. Here is a raw shot from the field. After a cleaning and application of a thin thin layer of washable Elmer’s glue and water to make it pop more. Picture with a scale. I also found this quality prosoma. I did find 2 other partial prosomas, body segments, a telson (mostly covered), a mouth plate with nice teeth, and I took home a few chucks of the Phelps member to freeze thaw. Never know right?! All my finds are in rubble so I might as well bring some rubble home haha. That’s all, just really excited..... Al

Hey everyone, I had an entire free afternoon yesterday so made my way out to DSR and Briggs rd. I haven’t been out there since the group hunt and I was curious to see if I could find pickings to split. I did a good amount of slab tossing and I know others did as well. People also got some newer areas going also and I was curious if I could work off those too. I started the day at Briggs rd because I did so well last time I was there. I was drooling for a 2nd shot! I didn’t find anything top shelf worthy but I did seem to stumble on more dipleura than I did the last couple visits. These are the total spoils from Briggs rd. I don’t know how common dipleura is at Briggs or if they ever come complete but these are my best dipleura so far from Briggs rd. They sure don’t show up like the Eldredgeops lol. I just liked this cephalon lol. All alone popping out it the rock with great detail!! Basically I got a bunch of stuff like this. I did a ton of labor moving over burden so that perhaps in the future I can keep expanding the shelf I started. Kinda rough on the back but this overburden doesn’t remove itself! After a few hours I moved onto DSR to see what was left behind for me to find . With all the action at DSR with the group hunt something was bound to get missed!! I forgot to take pictures of the site when I was at DSR so all I have are the final spoils and some close ups of my favorite finds. DSR spoils I wasn’t at DSR as long cause I was so tired and worn out from Briggs rd so I didn’t do much slab removal or excavating. I spent most my time scouring over others discard piles looking for hidden gems! And gems I did find!!! I found this dipleura looking through some blocks that were pulled off the upper layer of the quarry. Dipleura tends to show up more in the upper strata. It’s missing the pygidium and the cephalon is tucked over. With some minor prep I should be able to expose the rest of the cephalon. Super happy about this find. In general I have been coming up empty with dipleura at both Briggs rd and DSR so it was a bonus. Last but not least....... Echinocaris punctata phyllocarid!!!! I found this just sitting out in the open face up. Most likely mistaken for a bivalve. I couldn’t believe it. My best phyllocarid carapace so far. It’s nearly perfect!!! I have to say this beats all my other finds for the day. Just sitting face up for me to find . Well that wraps it up. Fun time at Briggs rd and DSR with a couple exciting finds for me. Seems like every time I go out I comeback with something totally unexpected!! It just keeps me coming back for more . Hope everyone has a great mother’s day! Thanks for reading, Al

I am wondering if this sample is a trilobite. The second pic contains an additional sample. Both taken from the same rock.

I have always been quite fascinated with the early stages of development of life on Earth. My interest really picked up when I first discovered the Ediacaran biota, and who can blame me. Those creatures are so enigmatic and fascinating. I was able to pick up a few specimens, but quickly realized that my desire for fossils greatly outweighed the supply and cost of Ediacaran fossils, and I soon discovered the equally fascinating and enigmatic Lower Cambrian Chengjiang biota. I was, and still am, blown away at the quality of preservation of these soft bodied critters. A lot of specimens come very shoddily or incompletely prepared, and while it's been a steep learning curve, I feel that I'm starting to get the hang of prepping them. I've decided to start posting my latest acquisitions as these fossils are too amazing not to share. First up is Cricocosmia jinningensis, a fairly common palaeoscolecid worm from the Chengjiang biota. I have several specimens but this one is the best. It came partially prepped and I am just now satisfied with the result. You can see remnants of the gut preserved as darker regions in the center of the body. Next up is a small hash plate of Bohemiella romingeri brachiopods from the Middle Cambrian of the Czech Republic. Not my usual purchase, but I felt the specimen was too beautiful to pass up.

Found on a beach in Scotland. Matrix appears to be volcanic. Any clues?

What could this be? Just a rock or a fossil as i have theorized. My guess is that it could be a kind of marine fossilized arthropod, with fossilized inner organs, i know it is not very common but thats what makes more.sense to me. . It was found in the rivershore in Bilbao, in lower cretaceous sediments, i found some sea-urchin fossils there too. . Thanks a lot!

I made another day at my favorite hunting site. A cold and wet day. Didnt score anything really noticable, but this fat boy : Ectillaenus giganteus, who is actually "giganteus", complete and not that streched !

I was out at the North Sulfur River on Saturday. I found a number of cool things. This one is a mystery to me, but it seems very rare and pretty neat. I’m not sure it’s even really identifiable as to a class or order, but I thought I’d ask. It needs more prep, but I’m not sure how much more there is to uncover. Above you can see what look like 2 legs hanging down and possibly One on op. Below is the same thing invented. Another pic from a different angle. I can’t get any closer on the small details. I can see the texture of what I believe may be legs on the bottom of pic 1, but they aren’t crustacean legs. I guess they could be antennas, but I’m not sure antennas are segmented like that. If you look at what appears to be an appendage on the top it does have bumps on it. Any thoughts?

Hello! As a typical New York fossil hunter I have always had a special interest in Trilobites and Eurypterids. When I was in my undergrad in Buffalo I was able to get my hands on load of trilos but eurypterids were seemingly not available anymore outside of Lang’s quarry. I have found some luck at a roadcut in Litchfield, New York and these are the pictures I will share. It’s a very difficult place to dig honestly and I’m lucky to have a half decent little Eurypterid. I really want to dig Ridgemount quarry. I hear people still go there but I’m not really sure how to go about it. In conclusion, here are my Litchfield NY finds! Al

This specimen is from the Pennsylvanian subsystem, Kansas City group, and probably the Winterset member. I say probably because I collected it several years ago and I'm not sure. If it is not from Winterset, then it is from a some other nearby member in the Kansas City Group. It seems that the only arthropods in the Winterset are trilobytes, so I'm thinking that this is not arthropod, even though it has that superficial appearance. Can you folks help me identify it?

What do you think these are? Sorry, this is the only picture, and there is literally 0 information, so just your best thoughts from what you see here. I'll update any info if I can.

A friend found a few small tubs of fossils that she hadn't seen in years until she started moving stuff around last week for a possible move. She asked me if I could come over and look at what she found. Most of the specimens don't have a label but some of it is obvious to anyone who's been to shows and had friends who collect fossils as well. I don't specialize in invertebrates or plants but I know an Elrathia from Utah, a Lovenia from Australia, and a Metasequoia from British Columbia when I see them because I have a few of each myself. She has some trilobites that are out of my wheelhouse so I thought I would ask the forum for identifications. The one below is from Morocco and apparently a Devonian form related to Phacops. I forgot to note the dimensions or ask for the photos to have a ruler included but the specimen is about an inch and a half (approx 4cm) as I recall. The second one is also from Morocco. I think that plate has two of the same (Cambrian and related to Paradoxides). The third is also from Morocco and Devonian, I think. Thanks for any info that can be provided especially if you have an idea of the general locality. I have a few more photos to post but have to go now. Jess

This 3" specimen was collected out of the Mazon Creek itself, near the Benson Farm. It was collected around 1998 and filed as Problematica. We are finally starting to identify these specimens. It is our specimen number S00051. At first, we thought it might be a shrimp similar to Kellibrooksia Macrogaster, but there isn't much evidence of the proper segmentation, and no legs.

Another fine find from Sacha's Merritt Island Micro Matrix. I'm thinking this is modern, and it has a crustacean vibe to it. Any clue as to what this might be? @old bones @MarcoSr
