mikeymig Posted December 20, 2013 Share Posted December 20, 2013 I just posted these photos to my FB page and wanted to share them here as well. The set of Platystomas range in size from .2" to 1.6" and they are from the Middle Devonian. The Platyceras was found this past season and its the spiniest gastropod I have ever found. This snail was found at my crinoid site and more then likely lived attached to a crinoid. thanks Mikey 1 Many times I've wondered how much there is to know. led zeppelin Link to comment Share on other sites More sharing options...

mikeymig Posted December 21, 2013 Author Share Posted December 21, 2013 Jed, all but the biggest snail was found lying on the surface. Mikey Many times I've wondered how much there is to know. led zeppelin Link to comment Share on other sites More sharing options...
Jeffrey P Posted December 21, 2013 Share Posted December 21, 2013 Mikey; Those are sweet. Never saw a spiny one before. Have you checked out my Lower Devonian Platystoma preserved in silica I posted late in the summer? You can see the basic similarities to your specimens. Glad to see another appreciating Devonian gastropods. Best wishes. Jeff Link to comment Share on other sites More sharing options...
mikeymig Posted December 21, 2013 Author Share Posted December 21, 2013 Nice Jeff, they look recent! I found some upper Devonian snails that were silicafied but they weren't loose. Cool!

Jeffrey P Posted December 21, 2013 Share Posted December 21, 2013 Mikey; Comparing your specimens and mine, I'm curious about the differences between Lower and Middle Devonian Platystoma. Mine I've identified as Platystoma ventricosa. Shell ornamentaion is for the most part absent from my specimens while yours have beautiful pronounced ribbing. Wonder if that's characteristic of that species or differences in preservation. Mine are also found eroded from a limestone shell bed over twelve feet thick composed over 99% with brachiopods. Gastropods and tentaculites make up less than 1% of the fauna and there's occasional very rare trilobite and cephalopod remains. Despite being overshadowed by the brachiopod fauna, I've collected over two dozen complete Platystoma and can usually count on a few every time I visit the site. I wonder what the faunal mix is at your Livingston Co. locality. Again, that spiny Platyceras is very cool. Best wishes and take care.

Wrangellian Posted January 12, 2014 Share Posted January 12, 2014 Count me as an appreciator of Devonian (Paleozoic generally) gastropods (mollusks generally) though I can't find any in my area. Those are very nice. Link to comment Share on other sites More sharing options...
hrguy54 Posted January 13, 2014 Share Posted January 13, 2014 Great finds and, I assume, prep. I find or see several similar pieces here in Southern Ohio every year, sort of.....it is always the top portion, the "hump". Often protruding out of a plate. They are either broken or so imbedded that they are not retrievable. Nice to see what they would look like. Link to comment Share on other sites More sharing options...
