Found this today in a farmers field. The area is 557 feet above sea level. Near Avon/Littleville NY in the Genesee Valley I am very new to collecting, so I have two questions... 1) It looks like it may be Lepadocrinites gobbardi, but I have no experience. The lightbulb like base DOES resemble that. 2) Just the base of the "lightbulb" is protruding from the rock....(i am not even sure what type of rock it is.) Limestone? Anyway, I am wondering when something like this is found, is there a process to that will reveal more of what is in the rock? Or, do you just stick with what you see? Could it be cracked open to reveal more? If so, are there people that can do that? Or, do you do that yourself? Thanks.

This may be a silly question, but how do I know if something is actually a fossil or just a weird shaped rock? Also, if anyone knows - how do these weird shaped rocks form in the slate/shale if they aren't fossils? Not looking for an ID (yet!), just trying to figure out how all the weirdly shaped rocks came to be! I went hiking with my mom in our backyard because she found what we believe to be nautiloid fragments (link to ID thread) and we wanted to see if we could get more. Well we found lots of oddly shaped rocks, but are unsure if they are actually anything. If it helps, we are in a creek in Groveland, Livingston County, New York. A geologist friend said that creek bed looks like shale slate. The only thing we pulled out that I have pictures of right now is a long wormy looking one. One picture of it in the rock and three after we got it out. I haven't been able to take any pictures with size reference sorry I don't have it with me right now, but from memory I'd estimate it's at least ~12-15 cm (5-6 inches). Thanks!

Hey everyone!! So I posted last week (sorry had the wrong link there for a minute!) - but my mom found some interesting things in our creek and it was suggested they might be nautiloid fragments! So obviously we went back to look for more. We found a ton of rocks that are similar. I think a lot of what we found might just be concretions but here are a few that seemed interesting to me and I'd love another opinion on! They all have some sort of hole/dimple which I'm not sure is something that occurs in concretions? If it helps - they were all found in the creek bed in Groveland, Livingston County, NY and a geologist friend said she believes the rock on the creek bed appears to be shale slate. I'm at work without a ruler right now, so I had to use the Mary Anning post card I have on my desk for scale haha. It is 6 inches (15.24 cm). I promise I'll get a ruler soon if I'm gonna keep asking for help!! Thanks in advance!!

Found as surface float on the scree pile at the Windom exposure. A very common fossil in Hamilton group sediments. Similar to Emanuella praeumbona, distinguished from E. praeumbona by the hinge width; the hinge of A. umbonata spans the width of the valve, while that of E. praeumbona is narrower. A. umbonata has a nearly flat brachial valve, while that of E. praeumbona shows a convex profile. Full-sized specimens of A. umbonata are also not as large as E. praeumbona. References: Wilson, K.

Appears to have been assigned to several genera over time, including Stenocisma and Cupularostrum. Refs: Linsley, D. M. Devonian Paleontology of New York.

Found as surface float on the scree pile at the Windom exposure. Possible undescribed species of genus Cyrtina. Closely resembles C. hamiltomensis, but surface is smooth and punctate, rather than covered in tiny spicules. Also differs in that extremities are slightly rounded, rather than squared, and height of interarea is equal to the width rather than smaller. References: Ehlers, G. M.

Found as surface float on the scree pile at the Kashong exposure. Originally assigned to Delthyris, reassigned to Spirifer, Acrospirifer, and Patriaspirifer. Alternate spellings: P. duodenaris, P. duodenaria, P. duodenarius. Does not appear in Fossilworks or Wilson’s “Field Guide to the Devonian Fossils of New York”. Classification information from Fossilworks entry for Patriaspirifer genus. Reference: Linsley, D. M. Devonian Paleontology of New York.
