Fish and Insect Fossils from the McAbee Deposit
Page 1 of 3

In addition to plant fossils, fish and insect fossils are relatively abundant at the McAbee site. These fossils are often well preserved and provide valuable information about some of the inhabitants of the lake ecosystem.

The fish fossils at McAbee have been previously studied and described by Dr. MarkV.H. Wilson (see reference at the end of this article). The majority of the fish fossils are represented by a single species has been found in the lake deposit. Eohiodon rosei is an extinct relative of the modern mooneyes that survive in North America east of the Rocky Mountains. They are typically about 7.5 cm (3 inches) in length. At least two species of Eohiodon fossils have been found from several of the Okanogan Highland fossil localities, as well as the Eocene Clarno Formation of Oregon, the Eocene Green River Formation of Wyoming and in Oligocene deposits of Montana (Wilson, 1977). Rare partial specimens of a larger fish species have also been found at McAbee, but these have not been identified or described as of yet.
