Agatized Prehistoric Sea Turtle Egg Embryo Petrified Fossil Christmas Gift WoW!

Description

The images in this listing have been magnified 1-4 times, see below. As well, a back light was used to illuminate the embryo.
This amazing specimen I found along the Willamette River here in Oregon.  I've done a fair amount of research over the past couple years, and I believe this to be probably a sea turtle, since our area had been below sea level many thousands of years ago.
It measures 2 inches tall and is about an 1 inch thick. Thank you so much for looking!
