'Swamp king' prehistoric crocodile identified in Australia

Scientists in オーストラリア have identified a new species of prehistoric crocodile they have christened theswamp king.

The creature, officially named Paludirex vincenti, measured more than 16 足 (five meters) long and dominated waterways in southeastern Queensland, according to a press release from the University of Queensland (UQ) published Monday.
It lived between 5.33 そして 2.58 百万年前, researcher Jorgo Ristevski, a PhD candidate at UQ’s School of Biological Sciences, told PeerJ, the journal which published the research.
Researchers identified the giant crocodile from fossils dug up in the 1980s near a town named Chinchilla.
    The species is named after Geoff Vincent, who found a fossilized skull of the prehistoric animal. “Paludirexmeans swamp king in Latin andvincentihonors Vincent, according to Ristevski,
    Paludirex vincenti compared to a human.

    The ‘swamp kingwas one intimidating croc,” said Ristevski in the press release. “Its fossilized skull measures around 65 centimeters, so we estimate Paludirex vincenti was at least five meters long.

    But Paludirex had a broader, more heavy-set skull so it would’ve resembled an Indo-Pacific crocodile on steroids,” said Ristevski.
    Researchers identified the new species using fossilized skull pieces.

    The species was one of the top predators in Australia at the time it lived, and would have been able to eat giant prehistoric marsupials, according to the press release.
    Two species of crocodileCrocodylus porosus and Crocodylus johnstonistill live in Australia today, and it is not clear why Paludirex vincenti died out.
    Whether Paludirex vincenti went extinct as a result of competition with species like Crocodylus porosus is hard to say,” said Steve Salisbury, senior lecturer in the School of Biological Sciences and Ristevski’s supervisor at UQ.
    The alternative is that it went extinct as the climate dried, and the river systems it once inhabited contractedwe’re currently investigating both scenarios.
      9月中, an enormous saltwater crocodile (Crocodylus porosus) measuring 14.4 足 (4.4 メートル) was caught at a remote tourist hotspot in Australia’s Northern Territory.
      The crocodile, estimated to weigh 771 ポンド (350 kilograms), was captured by wildlife rangers at a trap in the Flora River Nature Park, a popular tourist destination southwest of the outback town of Katherine.
