Bretzia pseudalces, is an extinct species of deer from the extinct genus Bretzia. Endemic to North America, with fossils found in the Ringold Formation in Washington.

Taxonomy and evolution

The genus Bretzia was named in 1974 by paleontologist Eric Paul Gustafson and his colleague Willis Fry. It was named after geologist J. Harlan Bretz. Bretzia pseudalces is notable for being one of the first deer to live in North America, and one of the earliest ancestors to all New World Deer. Fossils of sister species Bretzia nebrascensis has been found in Nebraska and South Dakota

Description

Bretzia pseudalces is known from fossils of its jaws, teeth, leg bones, vertebrae, and antlers, and overall had approximately the same body size as a modern mule deer. However, it is easily distinguished by its dramatic antlers, which form a large palmate structure from a single anterior tine and posterior beam, superficially resembling a modern moose antlers.

Paleoecology

Bretzia pseudalces fossils are found with Teleoceras, Platygonus and Megatylopus, indicating they lived in the same space. The environment would have been mild and temperate, but seasonal, allowing for water levels to rise and fall. The majority of Psudalces fossils recovered from White Bluffs in the Ringold formation were degraded to various degrees, and bones of fish and small rodents were most commonly found with them, indicating that they were buried in silt and mud from riparian areas, including marshes or oxbow lakes.
