Parictis is an extinct arctoid belonging to the family Subparictidae.

Taxonomy & evolution

It was originally described as a new genus and species Parietis princeous of mustelid by Scott in 1893, for a single specimen, a mandible fragment with two anterior molars.[1] An alternative name and spelling, ?Parictis princeps, was proposed in 1894;[2] and in 1904 both the genus and species name were declared to be in error and the name Parictis primaevus was assigned.[3]

Parictis bathygenus was described in 1947, but it was considered a different genus by 1958, and a synonym of Cynelos caroniavorus by 1976.[4][5]

Another species was described in 1954 as Campylocynodon personi,[6] and was reassigned to the genus Parictis in 1967.[7] And Parictis major was described during a review of the genus in 1972.[8]

The genus as a whole was placed within various families, including

Ursidae by Hunt in 1998.[9][10] It is placed within the family Subparictidae as of 2023.[11]

Description

It was a very small and graceful

Amphicynodontinae into the Hemicyoninae in Asia.[13] Although no Parictis fossils have been found in East Asia, Parictis does appear in Eurasia and Africa, but not until the Miocene.[12]
