Found this while digging in red clay on my ranch. Seems to be made of minerals like quarts crystal ect. It's approx. As big as my hand from tip of middle finger to palm. U can actually see an entire eyeball completely in tact with a pupil and eye color. U can also see the brain exposed as well.
I discovered this peice on my 50 acre ranch in California while exploring in the back field digging in the red clay. There has also been a huge discovery on the neighboring property said to be the largest fossil find in California's history by an east bay mud employee working a t pardee dam recreational park in valley springs ca
