What do you think?

Any advice and or comments etc are welcome. So thanks in advance I've probably 1000 or more pieces I myself have found n God only knows how much more is waiting to be discovered just on my property alone..it's really everywhere in my area of my state..whats puzzling to me however is why my University it's anthropology dept along with those individuals in my area who's business it is to know the who what when n how are denying that any of it exists and have old me I'm seeing things and worse have attacked my character in an attempt to shame me n make me look pitiful .. so I'll post my pics of some of what I've found and let y'all decide now keep in mind it's old it's dirty n most cases fossilized remnants of materials used to create their art their tools their accessories etc and as such can be for some difficult to identify with absolute certainty ..

The first one reminds me of a piece of fossilized turtle carapace....
This one looks right on both sides, with common figuration and shape, and possibly some quite intricate details.

The anthropologist's are either A, have not caught on and are clueless   B, Realize almost everything they think they know is complete garbage, and are in denial   or C, are part of conspiracy to hide our true origins...

D..all the above
