MammothPaleoGuy Posted June 22, 2012 Share Posted June 22, 2012 (edited) Greetings All; Thanks in no small part to the help I've gotten here on the forums, I managed to get my fossil dig / identification class off the ground. So far we've had around 400 kids sorting through gravel from Florida and North Carolina, identifying and keeping what they find. I've been stumped by a recent find, however -- a bilatterally symetrical, roughly t-shaped thing about 4mm X 4mm. It's from the Aurora Mine in North Carolina. To me the material looks a little like urchin test, but as the shape is so peculiar I am by no means sure. The scale in the background is 5mm X 5mm. Any ideas?

sward Posted June 22, 2012 Share Posted June 22, 2012 I can't help with the id, but congratulations on getting your classes started. 400 kids already...that sounds like a good start.

MammothPaleoGuy Posted June 29, 2012 Author Share Posted June 29, 2012 Sward, thanks for the kudos -- we're pretty proud of how the activity went. Indy: It could be a crinoid, but it would be pretty unusual, as there aren't any other pieces there. It does sorta look echinodermal, but I don't THINK its a crinoid.

Al Dente Posted June 29, 2012 Share Posted June 29, 2012 It is the plate that overhangs the peristome on the irregular echinoid Echinocardium. At Lee Creek, Echinocardium are found in the Pliocene Yorktown Formation.
