BassaricyonAmphicyon, Arctictis and Eofelis

Bassaricyon gabbi (Allen 1876) is the extant olingo or olinguito, traditionally considered a member of the raccoon clade native to Central American rainforests. Here it nests with the kinkajou, Potos. This omnivore is arboreal, nocturnal and solitary.

Eofelis sp (Kretzoi 1938, Peigné 2001, MA-PHQ 348, ) was considered an early member of the Nimravinae, a cat-like clade often with saberteeth. Here it nests with the more primtivie Mustela, a European mink and a member of the weasel family.

Arctictis binturong (Raffles 1822, up 90cm svl = a 75cm tail) is the extant binturong, a vivverid close to the bear-dog, Amphicyon. A prehensile tail, as in Nandinia, is retained. The vomers separate the palatal maxillae. Two or three molars are present.

Amphicyon idoneus (YPM VP.013134) was originally considered a bear dog.

Amphicyon longiramus (Lartet 1836, Blainville 1841; Mid-Miocene to Pliocene, 16–9mya; up to 2.5m) is the wide ranging bone-crushing, bear-dog. This is a wastebasket taxon with some specimens (A. longiramus) related to dogs, others (A. galushi) related to hyaenas, while still others (lower right above) nesting between Arctyocyon and Thylacinus.

Amphicyon galushai (Hunt 2003) is a sister to the extant binturong, Arctictis, in the LRT, both nesting with arboreal carnivores like Eofelis.
