Boremys is an extinct genus of baenid turtle from the Late Cretaceous and early Paleocene of North America.
Naming and description
It is known from two species, the first being
B. pulchra named in 1906 by Lawrence M. Lambe for a partial
plastron and
carapace from the
Campanian Dinosaur Park Formation of
Alberta as a species of the extinct turtle
Baena, before being reassigned to the new genus
Boremys later that year. The second valid species is
B. grandis, named in 1935 by Charles W. Gilmore for a near complete shell from the Campanian Kirtland Formation of
New Mexico. A third species,
B. albertensis, was named by Gilmore in 1920 but is now recognized as a
junior synonym of
B. pulchra. Additional material of an uncertain species of
Boremys, from the Hell Creek Formation of
Montana and the Fort Union Formation of
Texas, show that
Boremys survived the
K-T Extinction and lived at least into the early Paleocene.
