Scientists have discovered a new species of marsupial in Australia\u2019s bushland, closely related to the kangaroo.<\/p>\n

Researchers have identified a new species of bushland marsupial that is closely related to kangaroos. Unfortunately, evidence suggests this species has already disappeared.<\/p>\n

The discovery came after scientists from Curtin University, the Western Australian Museum, and Murdoch University examined fossil remains found in caves across the Nullarbor and southwestern Australia. Their analysis revealed not only a previously unknown species of bettong but also two new subspecies of woylie.<\/p>\n

Woylies: Small but Powerful Ecosystem Engineers<\/p>\n

Woylies, also called brush-tailed bettongs, play an important role in their environment. These small marsupials can shift several tons of soil each year while digging for the underground fungi they prefer to eat. Native to Western Australia, woylies are also the most frequently relocated mammal in the country, moved between areas as part of programs designed to safeguard the critically endangered species.<\/p>\n

Lead author Mr. Jake Newman-Martin, a PhD student in Curtin\u2019s School of Molecular and Life Sciences, said the discovery unlocked vital clues about the diversity of woylies, also known as brush-tailed bettong.<\/p>\n

\u201cWoylies are critically endangered marsupials that have been the focus of conservation efforts for decades,\u201d Mr. Newman-Martin said.<\/p>\n

\u201cIn this new research, we\u2019ve named a completely new species based on fossil material, and two new subspecies of woylies for the first time. Sadly, many of them have become extinct before we\u2019ve even been aware of them.<\/p>\n

\u201cOur results split the critically endangered woylie into two living subspecies, which is very important for conservation when we\u2019re considering breeding and translocation initiatives to increase the size and fitness of populations.\u201d<\/p>\n

Expanding Knowledge Through Fossil Analysis<\/p>\n

Co-author Dr. Kenny Travouillon, Curator of Terrestrial Zoology at the Western Australian Museum, said researchers used bone measurements to assess the diversity of woylies and the number of species.<\/p>\n

\u201cThis research confirmed several distinct species and expanded the known diversity of woylies by measuring skull and body fossil material that had previously not been looked at in detail,\u201d Dr. Travouillon said.<\/p>\n

\u201cWhat we\u2019ve found through this research tells us that examining fossils alongside genetic tools could offer significant insights that may help conservation efforts of this critically endangered native species.\u201d<\/p>\n

The scientific name of the new Nullarbor species has been described as Bettongia haoucharae but the researchers will work with Indigenous people to identify an appropriate collaborative name given woylie is a Noongar word.<\/p>\n
