I was driving north on Interstate 35 near Waxahachie, Texas this afternoon. Saw pile of rock debris that were up 60 feet high near the Interstate 35 service road. I couldn't resist passing by, so I parked near the service road and walked around the debris for any fossils. Well, most of the fossils I found are small to large Inceramous clams. Not too much spectacular, but the clam attached to the matrix were near complete. Some of these clams have pyrite rust stains on them. Formation is Austin Chalk (upper Cretaceous).
