Researchers examining the body of an entirely safeguarded Ice Age pup have made a startling disclosure - a bit of what could be one of the last wooly rhinos inside its stomach.
Russian analysts initially unearthed the saved, textured body of the canine - which could be a canine or a wolf - from a site in Tumat, Siberia, in 2011.
Inside the 14,000-year-old doggy's stomach was a shaggy bit of tissue. From the start, researchers accepted the piece had a place with a cavern lion, as a result of its fine yellow hide. Be that as it may, tests by specialists at Stockholm's Natural History Museum recounted to an alternate story.
"When they got the DNA back, it didn't look like a cave lion," Love Dalen, a professor of evolutionary genetics at the Centre for Palaeogenetics, a joint venture between Stockholm University and the Swedish Museum of Natural History, told CNN.
"We have a reference database and mitochondrial DNA from all mammals, so we checked the sequence data against that and the results that came back -- it was an almost perfect match for woolly rhinoceros," Dalen said.
"It's completely unheard of. I'm not aware of any frozen Ice Age carnivore where they have found pieces of tissue inside," he said.
After radiocarbon dating the example, specialists confirmed that the rhino skin was around 14,400 years of age.
"This puppy, we know already, has been dated to roughly 14,000 years ago. We also know that the woolly rhinoceros goes extinct 14,000 years ago. So, potentially, this puppy has eaten one of the last remaining woolly rhinos," he said.
Researchers don't have a clue how the doggy came to have a bit of rhino in its stomach.
Edana Lord, a PhD understudy at the Center for Palaeogenetics who co-wrote a paper contemplating the end of the wooly rhino, disclosed to CNN that the animals would have been generally a similar size as the cutting edge white rhino - making it far-fetched that the little dog murdered the monster itself.
The scientists additionally thought that it was interested that the little dog passed on not long after eating the rhino.
"This puppy must have died very shortly after eating the rhino, because it's not very digested," Dalen told CNN.
"We don't know if it was a wolf, but if it was a wolf cub, maybe it came across a baby rhino that was dead, or the (adult) wolf ate the baby rhino," he speculated. "Maybe as they were eating it, the mother rhino had her revenge."
