What are these?

[Guest 1551]

I used to know, but I forgot [emoji23] I always find them.

Looks to me but not sure to be musical instrument reeds. I'm sure someone on the forum will help.

These are the flex osteoderms to a nine-banded armadillo...the part of the shell that allows the armadillo to roll up and protect itself.

Here's a photo comparing some different armadillo osteoderms:

To the far left is a modern nine banded armadillo (Dasypus novemcinctus) flex osteoderm (top) and normal osteoderm (bottom). To the right of that is a larger extinct cousin of the modern armadillo from the same genus, Dasypus bellus. The next osteoderms are from the giant armadillo, Holmesina. The far right and largest is Holmesina septentrionalis, and the smaller of the two giant armadillo osteoderms is Holmesina floridanus.
