sTamprockcoin Posted March 25, 2017 Share Posted March 25, 2017 I spent the afternoon fossiling. I've always called these turnitella. Is this correct/are they even identifiable? They're from the Surilian - Wills Creek Formation. I did no prep except a quick rinse. I'm looking forward to working on these. I've also posted in the Pennsylvania section 3 different "forms" of Favosites that I found in the same formation. “Beautiful is what we see. More beautiful is what we understand.

westcoast Posted March 25, 2017 Share Posted March 25, 2017 That is a really nice slab of gastropods. I would have called them turritella too but others will have more to say on that... Link to comment Share on other sites More sharing options...
sTamprockcoin Posted March 25, 2017 Author Share Posted March 25, 2017 That's actually 3 different samples and there's more out there I only spent about 20 minutes there. “Beautiful is what we see.

abyssunder Posted March 25, 2017 Share Posted March 25, 2017 Nice ones. Unfortunately, they can't be Turritella gastropods with temporal range from Cretaceous to recent. Wills Creek Formation of Pennsylvania, Maryland, Virginia, and West Virginia is Silurian in age and contains fossils from the Pridoli to the Ludlow epoch. Maybe, Turnitella ? 2 " We are not separate and independent entities, but like links in a chain, and we could not by any means be what we are without those who went before us and showed us the way.

doushantuo Posted March 26, 2017 Share Posted March 26, 2017 maybe Murchisonia? 1 Link to comment Share on other sites More sharing options...
abyssunder Posted March 26, 2017 Share Posted March 26, 2017 (edited) I think Hormotoma would be a good candidate. Also, I'm wondering if they couldn't be from the Mckenzie formation, rather than from Wills Creek Formation.

sTamprockcoin Posted March 26, 2017 Author Share Posted March 26, 2017 The location is definitely Wills Creek formation as per the interactive PA geologic survey map and the Blair County Geology report. “Beautiful is what we see.

Jeffrey P Posted March 26, 2017 Share Posted March 26, 2017 Really nice collection of gastropod internal molds there, Tim. Without surface features of the shells such as ribbing or ornamentation it will be difficult to come up with a precise ID, but Hormotoma looks like a decent guess. Glad to see you're getting out and sharing your finds with us. Link to comment Share on other sites More sharing options...

Ludwigia Posted March 26, 2017 Share Posted March 26, 2017 I'll also go with Hormotoma, but only because I don't know many other paleozoic gastropods that look like those. It does occur in the Silurian at any rate. Greetings from the Lake of Constance. Roger http://www.steinkern.de/ Link to comment Share on other sites More sharing options...

Also, I'm wondering if they couldn't be from the Mckenzie formation, rather than from Wills Creek Formation. I agree Holotoma sp. is probably it. I think this is probably Wills Creek material we're looking at. Gastropods like these are quite common in some of the limestone layers, where as the McKenzie tends to be mostly just ostracodes, brachiopods and hash material (by the way, be on the lookout for ostracoderm plates when you're in the transitional zones in the Wills Creek). I have a bunch of McKenzie Formation stuff from near one of Jasper Burn's old sites that I could post, lots of hash limestone with crinoids and brachiopods. Unfortunately I only found a couple of trilobite molt fragments, and no eurypterids (the two things I wanted to find the most!). Link to comment Share on other sites More sharing options...
sTamprockcoin Posted April 11, 2017 Author Share Posted April 11, 2017 This locality is a highway road cut almost in the middle of a 3 mile long ridge. Jeff P collected localities along the ride last fall. I have seen a nice variety of fauna from ostracodes to trilobites! There are numerous cuts created by shopping plazas along the ridge so its easy collecting from a fairly soft formation. “Beautiful is what we see. More beautiful is what we understand.
