40,000-Year-Old Bear-Like Wolf Found Preserved in Siberian Permafrost
TEHRAN (Tasnim) – A giant wolf head preserved since the last Ice Age has been found in incredible condition in Siberia.
The head, discovered by a local man in 2018 along the shores of the Tirekhtyakh River in the Russian Republic of Sakha (aka Yakutia), measures a whole 40 centimeters in length (about 16 inches), making it unlike any existing wolf specimen scientists have studied from so long ago, Science Alert reported.
"This is a unique discovery of the first ever remains of a fully grown Pleistocene wolf with its tissue preserved," paleontologist Albert Protopopov from the Republic of Sakha Academy of Sciences told The Siberian Times.
"We will be comparing it to modern-day wolves to understand how the species has evolved and to reconstruct its appearance."
The find, which follows the discovery of a number of ancient cave lion cubs in the same region in 2015 and 2017, represents another amazingly well-preserved animal recovered from Yakutia: its fur, fangs, skin tissue, and even brain tissue are still seemingly intact.
Protopopov, together with scientists from Sweden and Japan, is now studying the head, believed to be from an adult wolf two to four years old.
Their work will include analyzing the ancient animal's DNA, and using tomographic techniques to non-invasively see inside the skull.
According to Protopopov, finding wolf skulls in thawing Siberian permafrost isn't uncommon, but they're rarely on the same level as this massive, ancient predator.
"Several puppies have already been found," Protopopov told Russia's Interfax news agency.
"The uniqueness of this find is that we found the head of an adult wolf with perfectly preserved soft tissues and brain."
Alongside the wolf, the scientists are also examining a newly discovered cave lion cub, thought to be a female. The researchers think it may have died shortly after being born and then became preserved in ice.
Nicknamed Spartak, the cub is also in an incredibly undamaged state, giving scientists an amazing opportunity to study and learn more about these ancient specimens.
"Their muscles, organs and brains are in good condition," paleontologist Naoki Suzuki from the Jikei University School of Medicine in Tokyo told The Asahi Shimbun.
"We want to assess their physical capabilities and ecology by comparing them with lions and wolves of today."
