Nice negative
Genus: Crossopolis. Species: magnicaudatus.
This paddlefish is 55 million year's old. Found at the 7200 feet elevation in the Green River formation. Located near Kemmerer, Wyoming, USA.
The paddlefish are the rarest described fish in the Green River Formation, represented usually by incomplete specimens (partial skulls and tails) the body consists mostly of cartilage and notochordal tissue. They same to be found only in the Fossil Lake deposits. Paddlefish are still living today and are only found in two of the worlds large river systems. That is the Mississippi River system of North America and in the Yangtze River system in China.
This specimen is 25" long and the plate is 22" wide by 32" high and has a 5/8" wood backing with hanger attached and beautifully trimed.
This negative plate had only a bone but the emprint from a positive was so great in detail that I decided to enhance and preserve this specimen.
This plate has nice color contrast.

FANTASTIC FOSSIL BIRD!!
EXTREMELY RARE!!

Undetermined sp.
The Green River Formation has produced more complete or nearly complete articulated fossil birds than any other pre-Pleistocene locality in North America. Many of these birds (an Eocene galliform) were non-aquatic; they fell into the lake,somehow,and covered with sediment and fossilized in the same way the fish were. Feathers,legs,feet and skulls are more abundant than complete specimens (which are extremely rare).
This specimen is 7" long, skull is 1 3/4" long and the plate is 21" by 16" high. It also has 24 minni fish on the plate and has a 5/8" wood backing.
Very Excellent and Extremely Rare. No repair or touchup has been made to the bird specimen.
