Palm oil, tea, coffee, cacao, and rubber are the island's major crops. The woods produce export-quality timber, while the sea supplies tuna and prawns. Although over a third of the population of Papua New Guinea is Roman Catholic and more than a quarter is Lutheran, traditional religious beliefs and rites are still extensively observed, and the island's majority is animist.
The Sr ratios in the sample are consistent with those found in the Darling Downs area of central eastern Australia, where the fossil species was discovered, and suggest that the animal traveled around 200 kilometers every year. Outside of the region, Sr rations are much higher and lower. If Diprotodon traveled outside of this location, the Sr ratios from the incisor would have varied according to the area on which it munched. There is no other marsupial, alive or extinct, that migrates. While certain kangaroo species may be migratory, contemporary marsupials were formerly thought incapable of long-distance dispersion owing to their relatively lower body size in comparison to their migrating placental counterparts. The frequent two-way migrations seen in Diprotodon, on the other hand, demonstrate that large-bodied marsupials did move.
The majority of Australian animals are nocturnal or crepuscular, including the carnivorous marsupials. While the majority of species are nocturnal, some have been seen feeding and basking during the day in a number of species for which thorough field data are available, including antechinuses and thylacines. In certain populations, spotted-tailed quolls take advantage of chances to hunt nocturnal possum prey lying in tree hollows, and their activity is virtually arhythmic. Three species, the numbat, the speckled dasyure from New Guinea, and the southern dibbler (Parantechinus apicalis) from Western Australia, are mostly or totally diurnal.
Before we continue, it's important to recognize that the pouch is one of many distinguishing characteristics of marsupials; it is not the primary criteria for categorization. Not all marsupials have a permanently attached pouch. Indeed, several animals have just skin folds to shelter their babies. Additionally, members of this mammalian infraclass have a short gestation time and a lengthy nursing period. Essentially, the little time spent in the womb is complemented by the extended breastfeeding phase during which the young remain in the pouch and feed on the mother's milk. While infants are frail due to the brief gestation period, they do have powerful forelimbs that enable them to crawl out of the pouch to eat.
