Hmmmmm? Definitely different. My knee jerk reaction is, not Native American Indian.
Welcome to Tnet by the way! The basic material doesn't look like chert or flint. Whatever the white stuff is on the base material looks strange but interesting. Can you tell us more about how and where you found it?
Interesting for sure and I would have picked them up. Not sure what you have, almost looked like something melted onto the rock. Hope someone can help you. Welcome to the party. Happy Hunting!
Like the others have said Gar scales. Be looking real close if you have found these fossils in this area there are more and of different kinds. Nice find.
