This Knightia Fossil Fish has a well defined bone structure.
Knightia fish lived approximately 55 million years ago and their fossils are found in just one location - the Green River Shales in Wyoming, USA. These slender fish fed mainly on ostracods, algae, Diatoms and other small fish and swam in large shoals.
With its fine detail this fish fossil plate makes a wonderful gift for anyone interested in natural history.
These fossil fish have not been enhanced in any way, just the covering layer of limestone has been carefully removed to present beautiful fossils, showing the relief of the bones and fins.
Fish length ~ 9cm
