The more I looked at this stone and touched it, the more this thing looked like it was wrapped in some kind of reptile skin. It may just be a random rock. More photos if needed. Does this look like something you may have seen before?
It's mainly green/yellow in color except for the pattern on the rock. The skin like pattern is a very dark color, almost black. It's a very hard rock, not breakable. It seems to weigh what it should. Not too heavy or light. We were looking for fossils in a sand bar that was in the shallows of the Bogue Chitto River in Mt. Herman Louisiana. This river is fed by the Mississippi River. We found it a couple weeks after some severe weather. Rivers had gotten pretty high & were at flood stage. Once they receeded, we went on our adventure. We found several other fossils of shells, and small centipede looking fossils. We only picked this one up because it reminded us of an alligator toe.
