The cleavage stages of marsupial development are vary among groups and aspects of marsupial early development are not yet fully understood. Marsupials have a short gestation period—typically between 12 and 33 days, [ 38 ] but as low as 10 days in the case of the stripe-faced dunnart and as long as 38 days for the long-nosed potoroo .

The Macropodidae are an extant family of marsupial with the distinction of the ability to move bipedally on the hind legs, sometimes by jumping, as well as quadrupedally. They are herbivores , but some fossil genera like Ekaltadeta are hypothesised to have been carnivores . [ 1 ]

Modern marsupials are now understood to be an originally South American lineage that later reached Australia and diversified there in a massive adaptive radiation. [1] [2] Molecular data, including analysis of retrotransposon insertion sites in the nuclear DNA of a variety of marsupials, and the fossil evidence indicate that Ameridelphia might best be understood as an evolutionary grade.
The common spotted cuscus is about the size of a common house cat, weighing 1.5 to 6 kilograms (3.3 to 13.2 lb), body size about 35 to 65 centimetres (14 to 26 in) long, and a tail 32 to 60 centimetres (13 to 24 in) long. [5]
The Macropodiformes / m æ k r oʊ ˈ p ɒ d ɪ f ɔːr m iː z /, also known as macropods, are one of the three suborders of the large marsupial order Diprotodontia. They may in fact be nested within one of the suborders, Phalangeriformes. [2] Kangaroos, wallabies and allies, bettongs, potoroos and rat kangaroos are all members of this suborder.
Figure 1:In mammals, the quadrate and articular bones are small and part of the middle ear; the lower jaw consists only of dentary bone.. While living mammal species can be identified by the presence of milk-producing mammary glands in the females, other features are required when classifying fossils, because mammary glands and other soft-tissue features are not visible in fossils.
