Thylacinidae is an extinct family of carnivorous, superficially dog-like marsupials from the order Dasyuromorphia. The only species to survive into modern times was the thylacine (Thylacinus cynocephalus), which became extinct in 1936.
The consensus on placement of the family is with the Dasyuromorphia order, with agreement on the divergence this family and the Dasyuridae, represented by the extant quolls and Tasmanian devil Sarcophilus harrisii, remaining under consideration.
The thylacinid family was represented by two species in a synonymy published in 1982, the recently extinct Tasmanian tiger and the species Thylacinus potens, known by fossil material. Discoveries of new material, especially in well researched fossil depositions at the Riversleigh World Heritage Area, revealed a diverse array of genera and families existing during Miocene epoch. The dentition of specimens and some largely complete crania showed the development of specialist predators capable of hunting and consuming a range of vertebrate species, and like other mammalian predators, such as the canid family, could include herbivores larger than themselves. An assessment of the size range of the species has provided evidence of animals occupying a greater number of trophic levels and challenged the conception of the dominance of reptilians as large hyper-carnivorous predators on the Australia continent.[1]
The consensus of authors prior to 1982 was that the thylacinid family were related to the borhyaenidae, a group of South American predators, also extinct, that exhibited many similar characteristics of dentition. A review published in 1982 compared the skeletal structure of these groups, concluding the tarsal bones show greater affinity with the dasyurmorphs, strongly supporting the later theory that any dental similarities emerged independently.[2]
Another family, the Thylacoleonidae, were also large carnivorous marsupials, but allied to the order Vombatiformes and assumed to have also evolutionarily converged as predators of large herbivores.

Los tilacínidos (Thylacinidae) fueron una familia de marsupiales carnívoros del orden Dasyuromorphia propios de la fauna australiana. Con un rango fósil que comprende el intervalo Oligoceno - Holoceno, su representante más reciente, extinto en 1936, es Thylacinus cynocephalus, el tilacín o lobo marsupial. Se trata de animales poliprotodontos con una fórmula dentaria 4/3, 1/1, 3/3, 4/4 = 46.[1]

Les Thylacinidae étaient une famille de marsupiaux carnivores de l'ordre des Dasyuromorphia. Le seul membre à avoir vécu récemment est le loup de Tasmanie (Thylacinus cynocephalus), qui a disparu en 1936. Les autres animaux du groupe vivaient tous dans les temps préhistoriques en Australie.

La famiglia dei Tilacinidi (Thylacinidae Bonaparte, 1838), appartenente all'ordine dei Dasiuromorfi, comprendeva alcuni marsupiali esclusivamente carnivori. Tra tutte le specie che componevano la famiglia, solo una, il tilacino (Thylacinus cynocephalus), è sopravvissuta fino a tempi recenti, sebbene sia ormai estinta già dal 1936. Tutte le altre specie, diffuse solamente in Australia, vissero in epoca preistorica.
Il tilacino moderno apparve per la prima volta circa 4 milioni di anni fa. Le specie della famiglia Thylacinidae risalivano ai tempi del Miocene; dagli anni novanta sono stati scoperti almeno 7 fossili nel Queensland.[1][2] Il tilacino di Dickson (Nimbacinus dicksoni) è il più vecchio di questi fossili e si pensa possa risalire anche a 23 milioni di anni fa. Questo esemplare, inoltre, era di dimensioni più piccole rispetto ai tilacini moderni.[3] La specie più grande, il Thylacinus potens, poteva diventare grande come un lupo e fu l'unica a sopravvivere fino al tardo Miocene.[4]
