Remains Of Woolly Rhino Found In Stomach Of Ice Age Puppy

The wolf-dog hybrid was dated at 14,000 years old — and woolly rhinos are believed to have gone extinct around the same time.

In 2011, Russian researchers unearthed a perfectly preserved Ice Age puppy in Siberia. Recently, while examining the 14,000-year-old wolf-dog’s stomach contents, researchers were stunned to find evidence of what could be one of the last woolly rhinos on Earth still in its prehistoric bowels.

“It’s completely unheard of,” professor of evolutionary genetics Love Dalen said. “I’m not aware of any frozen Ice Age carnivore where they have found pieces of tissue inside.”

Scientists originally found the furry canine at a dig site in Tumat, Siberia and shortly afterward found a piece of yellow-haired tissue inside its stomach. Experts initially believed that the tissue belonged to a cave lion, but after sharing the evidence with a resourceful team in Sweden, learned otherwise.

“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 explained.

Dalen works at the Centre for Paleogenetics, which is a joint venture between Stockholm University and the Swedish Museum of Natural History, so his team had access to both highly-detailed DNA databases and radiocarbon dating.

After Dalen and his colleagues were able to assess with overwhelming likelihood that this half-digested tissue belonged to a woolly rhinoceros, they then radiocarbon dated it at around 14,400 years old.

“This puppy, we know already, has been dated to roughly 14,000 years ago,” said Dalen. “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.”

Modern research has shown that the woolly mammoth’s extinction was partly due to severe climate change. As for how this lucky puppy got its paws on such a specimen, which is the same size as a modern-day white rhino that weighs nearly 8,000 pounds and stands six feet tall, remains largely unclear.

Indeed, Edana Lord, a PhD student who co-authored a research paper studying the woolly rhino’s road to extinction, asserted that due to the rhino’s size it is impossible that the puppy killed the animal itself.

Additionally, experts were surprised to see that the rhino was left mostly undigested in the puppy’s stomach, leading Dalen to conclude that “this puppy must have died very shortly after eating the rhino.”

“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,” Dalen hypothesized. “Or the (adult) wolf ate the baby rhino. Maybe as they were eating it, the mother rhino had her revenge.”

This wolf-pup is just one of a few amazing prehistoric canines specimens to be found in the last decade. In 2016, a miner in the Yukon region of Canada found a mummified 50,000-year-old wolf pup alongside a prehistoric caribou. Then, in 2019, researchers found an 18,000-year-old wolf-dog hybrid perfectly preserved in the Siberian permafrost. They have since named that specimen “Dogor.”

Ultimately, researchers hope that this latest find can shed some more light on the last days of the woolly rhino — which are still being debated millennia later.

After learning about the stomach contents of an Ice Age puppy, read about the Russian lab that is seeking funds to bring back the woolly mammoth and woolly rhinoceros. Then, meet Stuckie, the mummified dog that’s been lodged in a tree for the last 50 years.
