Current Taxonomic Status of Late Cretaceous Species from the Western Interior Seaway

Jonathan R. Hendricks

Paleontological Research Institution, Ithaca, New York


The purpose of this page is to provide a listing of currently valid names of Late Cretaceous species from the Western Interior Seaway (WIS), as well as their synonymous equivalents. This listing is being used to standardize taxonomy across the CretaceousWorld TCN project. The corpus of taxonomic names is derived from the primary literature, as well as cataloged specimens in partner CretaceousWorld TCN collections. Taxa are treated at the family level and may be accessed via the links below. At the present time, all lists should be considered works in progress. A single listing of valid names of WIS species will be added at a later time.
