I found quite a few ammonites but didn’t think they were worth showing as I know them, but still want tips

Ventured into the Newark Super Group. Found some Upper Triassic aged fossils from the Lockatong Formation in SE Pennsylvania. Specifically Conchostracan, or Clam Shrimp. These are bivalved crustaceans that lived in a freshwater environment. Also included a couple photos of some non-fossil animals spotted on the trip.

About an inch and a half long, found in Surry, VA, on a miocene fossil shoreline, likely Yorktown Formation. Appears to have very fine striations/pores, which leads me to think its bone. Very light weight. The shape reminds me of an ear bone, but would like to have someone confirm.
