Phlaocyon annectens is an extinct species of the genus Phlaocyon, belonging to the subfamily Borophaginae and tribe Phlaocyonini, a canid endemic to central and western North America from the Late Oligocene to Early Miocene living 24.6—20.8 mya and existed for approximately 4.2 million years.

Taxonomy[]

Phlaocyon annectens was named by Peterson 1907. Its type locality is Beardog Hill, which is in a Harrisonian fluvial sandstone in the Upper Harrison Beds Formation of Nebraska. It was recombined as Phlaocyon annectens by Vanderhill (1980) and Wang, Tedford & Taylor 1999.

Morphology[]

Body mass[]

Legendre & Roth 1988 estimated the body mass of two specimens to be 1.81–1.87 kilograms (4.0–4.1 lb).
