Glironia venusta(Thomas 1912; snout-vent length 20cm) is the extant bushy-tailed opossum. It is nocturnal, arboreal, small and omnivorous. Here it nests with Late Jurassic Henkelotherium and Middle Jurassic Agilodocodon – and therefore probably had its own genesis in the Jurassic.Glironia lacks a marsupium (= pouch), by convergence with placentals, Descendant taxa, like Dromiciops, retain a pouch. |
