Marble Girl Posted January 21, 2013 Share Posted January 21, 2013 (edited) I was wondering if this piece is worth taking to a paleontology meeting tohicknh2o and I are going to this week. We visited the greensand marl pit a few weeks ago in NJ. We realize this is private property and Drexel Univ. has been doing wonderful work there. We walked the "trail" above and I stumbled upon this rock. Thought it was neat. The attached photo is the rock along side a small portobella mushroom for comparison. Ideas? Thanks! The only photo i have until later is this side view....which is consistent through the back. Hope it helps for now and I will post again when I get home.

Fossildude19 Posted January 21, 2013 Share Posted January 21, 2013 Looks like a geofact or concretion to me. Any pics of the opposite side?

squali Posted January 21, 2013 Share Posted January 21, 2013 I believe the formation at the top of the pit is the pennsauken. The formation has a high iron content as indicated by the orange/rust colored soils. This is most likely a concretion that may or may not of formed around an organic substance. It can't hurt to bring it to the DVPS meeting though. There will be several people there that are very knowledgeable about inversand It's hard to remember why you drained the swamp when your surrounded by alligators.

RichW9090 Posted January 22, 2013 Share Posted January 22, 2013 (edited) Yes, there is a small bit of Pensuaken at the top of the section, but, as I remember it, most of the yellow sandy layer was Cohansey Miocene.
