Found At Seven Stars PA a while ago, I am not sure weather this is a spine from the pygidium of a Greenops boothi, or if it is part of a phyllocarid telson. I am not an expert on arthropods, for all I know it could be a hyolithid (Hallotheca aclis). Adjacent fossil is a tiny gastropod, scale bar 5 mm.

ID help. Crustacean, mollusk, or something else? Upper carboniferous.
Gramps posted a topic in Fossil ID
I have found several of these in an outcropping of shale and limestone in the Iola Formation in Northeastern Oklahoma (middle Pennsylvanian). The longest dimension is about 15 mm (≈ 5/8 inch). Some of the other specimens are slightly larger, but all have the same pattern of bumps. (I photographed this one because it shows the least wear.) I’m wondering it might be the carapace of a phyllocarid or some other crustacean. Alternatively, it might be a bivalve or other mollusk. Any help with ID would be appreciated. Focus and exposure were difficult, so there are several images. Best wishes. -
Yesterday I was able to get out to Onondaga County in central NY. While I was there I got a chance to do some fossil hunting at two locations. The first was in Pompey Center, NY near Pratt’s Falls. The second location was a creek in Delphi Falls. The rock at both of these locations was the Skaneateles formation. I was able to get into a different formation at the second spot that was more shaly and had better preservation. This was my first time fossil hunting in the middle Devonian and I was amazed with the number of bivalves I found. (I’ve never found one in the lower Devonian near me). As w

I am new at this. I found possibly both halves of a phyllocarid(?) But not sure. It was found by me. Devonian. Found in shale outcrop Near Lebannon, NY. July 2022 Thanks for any info on this.

A day collecting elusive Mahantango Trilobites and Phyllocarids.
Dean Ruocco posted a topic in Fossil Hunting Trips
Hey everyone! The other day me and a few other experienced collectors spent the day out in the Mahantango formation. After moving a literal ton of material we each came home with about 3 or 4 complete trilobites and plenty of other neat associated fauna. I found 2 different specimens that are incredibly interesting/rare a complete trilobite, Dechenella (I have to take the head off the counter part and glue it back onto the body after prep it will be fully complete.). This means I have a complete specimen of every species of trilobite in the Mahantango except the elusive and rare Neometacanth- 4 replies

This is a great specimen of Rhinocaris columbina which I collected a couple summers ago. Both sides of the carapace are there as well as the majority of the telson, which is tucked around the underside of the rock.© Owen Yonkin 2022

My wife and I traveled up to western upstate NY this past weekend for Penn Dixie's annual dig with the experts event. This was our first visit to the park and we were happy to finally use up the tickets we had originally purchased for the 2020 dig. The event was sold out both days and the staff seemed happy to be back in normal operations. The weather was perfect, with bright sunny skies and temps in the 50s to 60s day 1 and 60s to low 70s day 2. Lots of folks digging: We didn't find anything crazy good, but didn't get blanked with a mix o

I have just found this little coprolite? yesterday. This is the second time a coprolite-like fossil has turned up in the shale from the Leighton Fm. I am not really sure on this one, though, due to the presence of crinoid stems. The fossil(s) are from the Leighton Formation, Maine; which is Pridoli, Silurian. The main reason I think it is a coprolite is because of its situation in the shale. The rest of the shale around it is relatively uniform, with no fossils whatsoever. The fossils present in it are one crinoid stem, quite a few ostracods, a very small Orbiculoidea brachiopod,

This morning I split this shale (technically it fell apart on me), and found this interesting little fossil. I was thinking that there was a possibility of it being a phyllocarid valve, but I have never seen one. This also raises a question that I have been wondering - how do you differentiate between a phyllocarid and a bivalve valve when the tail is absent? What raised my suspicions on this specimen are the raised bumps on the external mold and the depressions on the cast. The pictures below are of the specimen. The first shows the cast/internal mold, and the second the externa

Greetings, I found this in schuylkill county, Pennsylvania: part of the Mahantango formation. A couple people suggested that this could be a phyllocarid carapace, but I'm not sure... What do you guys think?

Taxonomy according to Schram and Horner, 1978, p. 394. Diagnosis (Schram and Horner, 1978, p. 394): "Rhinocarid of large size; carapace covered with hairlike ornament; furcae about 1 ½ times as long as the telson." Dithyrocaris rolfei, reconstruction from Schram and Horner, 1978, p. 395. Identified by oilshale using Schram and Horner, 1978. References: Schram, F. R. and Horner J.

Prepped Devonian Phyllocarid found in April 2021 New York
mikeymig posted a topic in Member Collections
Our recently discovered Devonian Phyllocarid is back from our preparator. Found on Collecting trip 4/9/2021 in New York state (#3 Phyllocarids we have with complete mandibles). This rare specimen has the classic pyritized Roemerella brachiopods attached to its carapace and the detail of the carapace itself is well preserved. What I was hoping and had very little chance of being antenna are serrated hinge lines. I never seen this on other specimens and the detail is amazing under magnification. The pincher like mandibles look to have color or pattern markings near the tips. I'm pretty sur- 9 replies
