This reminds me of the time a study group came from Berkeley out to the desert Southwest. They came to see what kind of plants they ground up because they were convinced they were mostly vegetarians and used their Matate grinding stones for grinding seeds and such. They found very little plant residue on the Matates, it was mostly all Mice, Rats, Ground Squirrels and Lizards that they were grinding to a paste. lol
Mmmm, lizard paste...
