WATERLINE Posted December 17, 2015 Share Posted December 17, 2015 This item I found while walking a dried up creek bed in the Catskills NY. At first it was nondescript but had a distinct layering which I split open.....The lump is Devonian...I think....and has an amazing amount of detailed 'flora/fauna' albeit marine in origin.... The Brachiopod mold was double sided and had an interior which came out on its own!!!! Bruce Link to comment Share on other sites More sharing options...
erose Posted December 17, 2015 Share Posted December 17, 2015 Nice find. The majority of the rocks within the Catskill Mountains are non-marine. If these were from up in the mountains this would be from one of the few marine layers scattered amongst the rest. But if you were on the flanks of the mountains it could be from one of the older formations which are mostly marine. With that big trilobite pygidium definitely worthy of more research.

ZiggieCie Posted December 17, 2015 Share Posted December 17, 2015 A good posability on your brach that came off, it may be the entire brachiopod and you have the top and bottom shells, as that type is very thin. An interesting hash plate. Link to comment Share on other sites More sharing options...
WATERLINE Posted December 17, 2015 Author Share Posted December 17, 2015 The area I was reviewing was near the town or Oak Hill and along the 'Catskill Creek' itself...This was back in late September and I have to say the lack of water flowing was disturbing...very dry.....Good fossil hunting never the less.

Jeffrey P Posted December 17, 2015 Share Posted December 17, 2015 That's an excellent piece. I can see some brachiopods and a trilobite pygidium (tail). Those are fairly uncommon in the Hudson Valley and Catskills. It's definitely Devonian, I'm guessing Lower Devonian but I'm not sure which formation. Congratulations on a nice find.

erose Posted December 17, 2015 Share Posted December 17, 2015 (edited) Definitely Devonian and I think your well into the Middle Devonian there. You need to get a hold of the geological map that covers that area. I think is the Mohawk-Hudson sheet but you can figure that out by looking into the publications and maps division of the NY Geological Survey: https://www.nysm.nysed.gov/nysgs/publications/index.html Edited December 17, 2015 by erose 1 Link to comment Share on other sites More sharing options...
Jeffrey P Posted December 18, 2015 Share Posted December 18, 2015 That area I believe is Upper Devonian terrestrial bedrock so the rock shown I think is most likely a glacial transport from the area to the north which has both Lower and Middle Devonian beds with rocks similar to this one. The Catskill Creek and other streams in the area display a wide variance in terms of flow, varying from a mere trickle to a raging torrent depending on the season and other factors. 2 Link to comment Share on other sites More sharing options...
