Cynarctoides roii is an extinct species of Cynarctoides, belonging to the subfamily Borophaginae and tribe Phlaocyonini, a canid which inhabited west central North America from the Late Oligocene to Miocene living 30.8—20.6 mya and existed for approximately 10.2 million years.

Taxonomy[edit]

Cynarctoides roii was named by Macdonald (1963). It was recombined as Cormocyon roii by Xiaoming Wang and Richard H. Tedford (1992) and Wang and Fremd (1994); it was recombined as Cynarctoides roii by Wang et al. (1999).[1][2]

Morphology[edit]

Body mass[edit]

Two specimens were examined by Legendre and Roth for body mass.[3]

  • Specimen 1 was estimated to weigh 0.644 kg (1.4 lb).
  • Specimen 2 was estimated to weigh 0.700 kg (1.5 lb).
