Weighing 110lbs (50kg) and measuring the identical dimension as a wolf, a mysterious species of big otter roamed the earth 6 million years in the past.
Researchers have found a fossil of the large otter within the shallow, swampy waters of historic Yunnan Province, Southwestern China.
This groundbreaking discovery now has scientists making an attempt to grasp different facets of the lifetime of the large otter.

The fossil was found by a world staff of researchers, led by the Pure Historical past Museum of Los Angeles County, whereas within the Yunnan Province.
The newly found species of otter, named Siamogale melilutra, was about the identical dimension as a wolf, and weighed 110lbs (50kg) – virtually twice as giant as the most important dwelling otters.
Till now, the traditional lineage of extinct otters, which matches again no less than 18 million years, was solely recognized from remoted tooth present in Thailand.
However researchers have now discovered a whole skull, mandible, dentition and varied skeletal parts.
Dr Denise Su, Curator & Head of Paleobotany and Paleoecology on the Cleveland Museum of Pure Historical past, mentioned: 'Whereas the skull is extremely full, it was flattened throughout the fossilization course of.
'The bones had been so delicate that we couldn't bodily restore the skull.
'As a substitute, we CT-scanned the specimen and nearly reconstructed it in a pc.'
The CT restoration revealed a mixture of otter-like and badger-like head and dental options

It had a big and highly effective jaw, with enlarged, bunodont (rounded) cheek tooth, which had been tailored for consuming giant shellfish and freshwater molluscs.
Dr Su mentioned: 'From the vegetation and different animal teams discovered at Shuitangba, we all know that it was a swampy, shallow lake with fairly dense vegetation.'

The Siamogale melilutra was not the one otter to have giant rounded tooth, which led researchers to query whether or not the trait was inherited from a standard ancestor.
Dr Xioming Wang, lead creator of the paper, mentioned: 'Our phylogenetic evaluation means that bunodont dentition independently appeared no less than thrice over the evolutionary historical past of otters.'
The researchers hope their discovering will assist to grasp different facets of the large otter's life.

Dr Wang added: 'The invention of the otter helps clear up some questions on otter relationships, however has opened the door to new questions.
'As an example, why was it so giant, how did it crack open mollusks and shellfish for meals, and the way did it transfer within the water and on land?'
Dr Su mentioned: 'Continued future research by our group will handle these elementary questions and provides us a extra full image of its paleobiology.'
The fossil was discovered within the Zhaotong Basin within the Yunnan Province, Southwest China
