A new species of Tymolus and a report on Metacarcinus (Crustacea: Decapoda: Brachyura) from the Miocene of Alaska
Bulletin of the Mizunami Fossil Museum, 33:47-57.
Tymolus alaskensis new species (Cyclodorippidae) is described from the Bear Lake Formation, a Miocene shallow water deposit from Alaska. The geographical range of the genus is extended to the northern-most margin of the Pacific basin. A large collection of Metacarcinus goederti Schweitzer and Feldmann, 2000 (Cancridae) permits a more complete description than was previously possible. Its occurrence in the Bear Lake Formation suggests a temperate-water depositional environment for the upper Bear Lake Formation
