Kangaroo with muscular body roamed Papua New Guinea 50,000 几年前

Meet Nombe Nombe! Bizarre giant kangaroo with a squat, muscular body roamed Papua New Guinea 50,000 几年前 – and was NOT closely related to Australian species

  • Scientists analysed fossils from the Nombe Rockshelter in Papua New Guinea
  • Their analayis reveals Nombe Nombe is a new species of ancient kangaroo
  • Rather than being closely related to Australian varieties, the new species most likely belongs to a unique genus, found only in Papua New Guinea
  • A bizarre giant kangaroo roamed Papua New Guinea 50,000 几年前, a new study has revealed.

    物种, which researchers from Flinders University have named Nombe nombe, had a squat, muscular body.

    Rather than being closely related to Australian varieties, the new species most likely belongs to a unique genus, found only in Papua New Guinea, 根据团队.

    ‘We think of these animals as being uniquely Australian, but they have this intriguing other life within New Guinea,’ said Isaac Kerr, an author of the study.

    How did Nombe Nombe end up in New Guinea?

    The study suggests that the species evolved from an ancient form of kangaroo that dispersed into New Guinea around 5-8 一百万年前.

    在那段时间内, the islands of New Guinea and mainland Australia were connected by a land-bridge, thanks to lower sea levels.

    Before the bridge was flooded and became the Torres Strait as it is today, it allowed early Australian mammals to move into New Guinea.

    The giant kangaroo was first described in 1983 and is known from fossils dating back 20,000-50,000 年份.

    The fossils come from the Nombe Rockshelter, a site in Chimbu Province that was once a diverse rainforest with thick undergrowth and a closed canopy.

    那里, Nombe evolved to have a thick jawbone and strong chewing muscles, that would have allowed it to eat tough leaves from trees and shrubs.

    ‘The New Guinean fauna is fascinating, but very few Australians have much of an idea of what’s actually there,’ Mr Kerr said.

    ‘There are several species of large, long-nosed, worm-eating echidna that are still around today, many different wallaby and possum species that we don’t get in Australia, and more still in the fossil record.

    The researchers used 3D imagery to study the fossilised jaw of Nombe.

    Before the bridge was flooded and became the Torres Strait as it is today, it allowed early Australian mammals to move into New Guinea.

    那里, the animals evolved to suit their new, tropical home, 根据研究人员.

    While several studies were carried out in the 1960s, 70s and 80s to study these extinct megafauna, no digs have taken place there since the early 90s.

    The researchers now seek to remedy this with further studies going forwards.

    Professor Gavin Prideaux, 该研究的合著者, 说过: ‘We’re very excited to undertake three palaeontological digs at two different sites in eastern and central PNG over the next three years.

    ‘We’ll be working with the curators of the Papua New Guinea Museum and Art Gallery and other contacts in PNG, with whom we hope to build some local interest in New Guinean palaeontology.
