Finds from North Sulfur River in Ladonia Texas.
Baculite part of a nautilus.
Baculite
Bits of Baculite
All the layers of a huge gryphea
On left 2 huge gryphea. Red and black baculite. the algea covered thin over TX I thought could be the underside of a sea urchin.
Sorry a few rocks snuck in there and at the top at first I thought it was a chunk of petrified wood but now am thinking it could be a wore down bone fragment.
