Found this piece on a walk near a Triassic outcrop in Pennsylvania, has a pretty exact visual similiarity to the wing rib of a Triassic reptile but is likely just some form of sedimentary trace. It would be great to get some more opinions on this piece to see if its worth holding onto or I would label it to be definitely sedimentary and rid of it, which I feel is the case.
A bit of sun yesterday helped here in Millrift PA , about 3 miles upriver from Port Jervis/Matamoras. The reference for this location is Atlas 228 plate 1 http://www.dcnr.state.pa.us/topogeo/publications/pgspub/atlas/index.htm. The U. Devonian Millrift Formation (530') is underlain by the Sloat Brook Formation (340') , Sparrow Bush Formation (40') and the M. Devonian Mahantango Formation (2450'). Cheers, Gordon
