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).
