Hoooooooooooorrrrrrrrrrrraaaaaaayyyyyyyyyyy!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! Here we are at last, into Adam's Silurian. Thanks for looking. First up is the Lower Silurian or Llandovery and I begin with a problem. I posted this one incorrectly in Adam's Ordovician as it had got it's label muddled up with an Ordovician Favosites I had that has vanished in the move here, but is being replaced by kind forum member @Herb Anyway, this, I remember now I've found the correct label, is from the greenish Browgill Formation, part of the Stockdale Group from a cutting near Skelgill (Skelghyll) in Cumbria, Northern England. It seems to be a tabulate coral, but I can't find any listed for this location, only mentions of small, rare, rugose corals. It has the star shaped corallites of a Heliolitidid, but seems to be tightly packed together like a Favositidid. A couple of species of Palaeofavosites seem to be close and are a bit star-shaped,, but anyone know any better? @TqB@piranha hmm who else? The coral bit, an external mold, is a maximum of 3.5 cm across and each corallite up to 2 mm.

I was wondering if I found an external mould of the Devonian gastropod Platyceras. The fossil curves in the rock which was hard to capture with the lighting. The rock was too big to carry back and I didn’t have a ruler with me so I apologize for lack of scale. Thanks!

Found this guy in crumbly shaley stuff, Monroe County, Indiana. The rippling shape reminds me a lot of a modern oyster shell. Closest thing I can match online is platyceras, but I don’t see any like this. The large associated crinoid plates are about 1/2” diameter for size reference. Is this worth prepping out and trying to glue together/consolidate?

Hey all, Decided to hit the Mahantango today. This spot has historically produced a complete trilobite during my hunting. While my collecting has become more selective as I have to try to keep storage in mind, I did pick up a few examples that I wanted to share. This I believe is a Platyceras? While I am getting more selective on keeping heads, I particularly liked this association of a head and pygidium. I do not believe these are the same specimen as the size and angles would be off but it did make me think of the rough sediments and potential storms that entombed these two together. Here I have some enrolled Eldregeops specimens, the leftmost is missing its head but flipped over does have the connected thorax. The centermost specimen is bisected and is only what you see in the picture, the other side is simply matching the matrix. Probably due to weathering out of the rock or splitting poorly, (I found him loose among the weathered material.) Additionally the rightmost specimens are complete (or relatively complete) and each show some great detailing of the compound eyes. The three rightmost specimens were found on my previous trip. Lastly, literally my final split of the day I uncovered this little creature! While only one of his spines was showing, I carefully hit the rock and was able to remove some more of the matrix around it. Additionally I managed to grab some more general trilobite material that will be used to give to other collectors in trades or will be donated to a home where they can help shed some light on the fascinating lives of these ancient creatures.

I am going to go to some real sites in eastern New York tomorrow, but I decided to check the rocks by a pond near my grandparents house where I found a couple trilobites and other Devonian fauna this summer. And I found this really nice Platyceras specimen which it turned out had a brachiopod fossil attached near the bottom, where the opening of the shell would be located. I highly doubt that these two organisms are articulated and fossilized together but I thought it was interesting and worth showing here.

I have a nice little gastropod in my collection, from my most recent trip to the Leighton formation. I am pretty certain that this is a Platyceras sp, such as the one shown in the plate below, figures 23 - 24. Boucot, A. J., Yochelson, E. L. (1966) Paleozoic Gastropoda from the Moose River Synclinorium, Northern Maine. Geological Survey Professional Paper, 503(A). https://pubs.usgs.gov/pp/0503a/report.pdf I do not believe that specimens such as these have been assigned to species as of yet, and would greatly appreciate to hear any insight on their taxonomy. The lifestyle of these gastropods is pretty interesting. It is thought that they attached themselves to the anal plates of crinoids, to feed on their excrement. There is some debate, though, that instead this species was a suspension feeder, or was parasitic, boring holes in through the crinoid's shell. The picture below is of my specimen. The tip, unfortunately, broke off, but the rest of the specimen is intact, though it is laterally compressed. It is from the Leighton Formation, which is Pridoli, Silurian. Thanks for reading!

Fossil forum, Good morning. I have been looking for literature on the following for a while now, and have not been successful. I was wondering if anyone already had information on the following, or can direct me to a place where I can look for it myself. Brachiopods, specifically Lingulids (classification and identification) Salopina genus ( classification and identification), this genus was moved from Orthis, for further clarification Rhychonellida (classification and identification, at least to the genus level). Camarotoechia genus (classification and identification); Strophomena genus (classification and identification); Gastropods, specifically Platyceras (classification and identification) Bivalves, specifically Modiolopsis and related genera (classification and identification) Ptychopteria genus (also known as Actinopteria). I am also interested in the fauna of fossil formations in northeastern Maine, specifically the Edmunds, Eastport, and Leighton formations. Thanks in advance!

Hi, I am looking for someone that can do a good (preferably great) job prepping out a fossil for me. I have a Platyceras that died still sucking the crinoids' backside. I don't have means or equipment to do a proper prep. If you do good work or know someone that does, I'd appreciate the contact. Unfortunately, I am somewhat cash poor but would like to perhaps work out some sort of trade for the work done. I have quite a few fossils or mineral specimens I could trade for the time. Thanks, caldigger

I went to the North Pit of Hungry Hollow for a few hours on Friday. I spent most of my time digging through the clay piles and walking around the water's edge, scoping out a few recognizable shapes that are by now completely camouflaged by the clay. It's amazing that my eyes even zeroed in on my tiny trilobites but I guess they had waited long enough for me to take them home, and today was the day! One trilobite turned out to be just the head but the other is pretty cute. I met one hiker from Pennsylvania (Greg) that came through the trail along the North side of the river. I introduced myself and we chatted for a few minutes. i always enjoy meeting tourists from different parts of the country. As I headed out, I decided to try the north cliff near the parking area and there I found a very nice Heteroschisma alatum (blastoid). It is about 1/4" wide and 3/8" long. In my pill bottle it went! I hope the photo is clear enough to see the detail. I got called back home or I would have stayed there a few more hours, even though the sun was beating down on me. Even one good find keeps me there longer than I anticipated! Incidentally, I went home with a large bag of garbage that I collected in the pit. I try to take anything out (cans, bottles, plastic bags etc) that I can, each time I go there and it always surprises me that I find more the next time I go. I hope people will be mindful that it's a privilege for us to be able to dig there at the generosity of the land owners. Please take your litter home with you. Detail is a bit clearer in the image above. I took the time to dig a few footholds so I wouldn't take a spill down the hill!
