Description:
This 50 million year old, Eocene-Era fossil fish comes from one
of the world's famous Laggerstatten, the Green River Formation
in Wyoming. A small portion of the fish fossils from Green River
exhibits such fine preservation. The significant extent of soft-tissue
preservation that makes the site famous is evident in this specimen.
This
one is Amia fragosa, a fossil relative of the modern bowfin
Amia calva. It is extremely rare, with only a few complete examples
known. It is even more rare than the gar, and highly prized by
collectors. Note the exceptional detail in the fins, teeth and
scales preserved in this almost 50 million year old example.
