Help requested: Western NY / PA Late Devonian eurypterids & sponges
pefty posted a topic in Fossil Hunting Trips
This Missourian is headed out to the Late Devonian of western New York state and Pennsylvania this coming week and hoping for a little help from y'all on localities for eurypterids and the sponge Hydnoceras. Are Clarke's (1920) Hydnoceras localities at Brown Hill (near Cohocton, NY) and Irish Hill (near Bath, NY) still productive and accessible? Are Ehlers' (1935) eurypterid localities at Bush Hill (near Smethport, PA)? Or are there other spots I should be checking out? I understand that the Trimmers Rock Formation in the vicinity of Bloomsburg, PA, is also worth a look for eurypterids, but I don't have any pinpoints mapped. If you're local to the area and want to show me the way yourself, I'll gladly bring you some Missouri crinoids Thanks in advance . . .- 3 replies

Anyone have Hexactinellida (Glass Sponges) from Penn DIxie?
DevonianDigger posted a topic in General Fossil Discussion
Hello, all! I'm working on an article presently about the existence of glass sponges in the Hamilton Group in New York state. The publications that I have found, most notably, The Great Glass-Sponge Colonies of the Devonian; Their Origin, Rise, and Disappearance, (Clarke, 1920)1 dispute their existence in the Hamilton group altogether. Recently, an example of an indet. Hexactinellida was presented to me from the site, and mention has been made of several others over the past 20 years having been found. I am wondering if anyone here in their vast array of experiences has encountered similar examples at the Penn Dixie site. If so, would you be willing to share photos and your information about where they were found? Thank you in advance! -J 1John M.
