Knightia fossil fish, framed. Measures 12.25"w x 10.5"t
Green River Formation, Wyoming
These are the fossil remains of a fish who lived during the Eocene
Epoch, over 50 million years ago. As the fish died, the remains settled
on the bottom of the lakebed and were covered with fine sediment.
Every fin and scale was covered so gently that every outline has been
preserved. Over millions of years, more mud and pressure transformed
the remains in to fossils. Eventually weathering eroded and exposed the fossils.
