abctriplets Posted December 24, 2016 Share Posted December 24, 2016 My kids found some fossils near Roanoke, VA - It looks like they are brachiopods and trace fossils from outcrops ranging from the Ordovician to the Mississippian. Can these be more specifically identified besides generic "brachiopods"? Thanks! Link to comment Share on other sites More sharing options...
abctriplets Posted December 24, 2016 Author Share Posted December 24, 2016 And these are trace fossils we think. Do these ever get more specifically identified by what made them? Link to comment Share on other sites More sharing options...
DenBoy Posted December 24, 2016 Share Posted December 24, 2016 The shells look like some kind of Rhynchonellida & the the third I would look at as possibly an eroded Echinoid but I'm no expert. And have yet to fossil in the USA. Last one looks like worm casts. But they look like great finds. Link to comment Share on other sites More sharing options...
Fossildude19 Posted December 24, 2016 Share Posted December 24, 2016 Much of what you are showing is incomplete bits and pieces. Some of the invert guys should be able to give you some ideas. @Shamalama Tim - VETERAN SHALE SPLITTER VFOTM --- APRIL - 2015 __________________________________________________ "In every walk with nature one receives far more than he seeks."

trisk Posted December 24, 2016 Share Posted December 24, 2016 The circular trace fossils could be impressions left by crinoid column segments (The raised circles on the bottom left resemble fragments of actual columnals). That could explain the sizes and why the rings are so well-defined and consistent in thickness. This was a hypothesis for similar-looking traces: http://www.ispotnature.org/node/470020 Link to comment Share on other sites More sharing options...
