Cave yields marsupial fossil haul
Fossil hunters in Australia have discovered a cave filled with the 15-million-year-old remains of prehistoric marsupials.
The rare haul of fossils includes 26 skulls from an extinct, sheep-sized marsupial with giant claws.
The beautifully-preserved remains have been described in the Journal of Vertebrate Paleontology.
“It’s given us a window into the past of Australia that we simply didn’t even have a pigeonhole into before.
“It’s an extra insight into some of the strangest animals you could possibly imagine.”
The giant-clawed, wombat-sized marsupial is named Nimbadon lavarackorum; researchers discovered the first of the Nimbadon skulls in 1993.
The palaeontologists have been stunned at how well preserved the fossils were – and by how many were found.
Discovering such a large assemblage suggests the animals may have travelled in herds – like modern-day kangaroos, said palaeontologist Karen Black, who led the research team.
