A juvenile mammoth, nicknamed Yuka, was found entombed in Siberian ice near the shores of the Arctic Ocean and shows signs of being cut open by ancient people. The remarkably well preserved frozen carcass was discovered in Siberia as part of a BBC/Discovery Channel-funded expedition and is believed to be...

The smallest dwarf mammoth, standing at under 4 feet (about 1 meter) at the shoulders, has been uncovered on the Greek island of Crete, researchers say. These findings could help yield insights as to how giant animals can shrink to tiny sizes over evolutionary time, scientists added. Dwarfism often happens...

Woolly mammoths were apparently driven to extinction by a multitude of culprits, with climate change, human hunters and shifting habitats all playing a part in the long decline of these giants, researchers say. Woolly mammoths (Mammuthus primigenius) wandered the planet for about 250,000 years, ranging from Europe to Asia to...

An 11-year-old boy in Russia's far north found the frozen carcass of a woolly mammoth with soft tissue, skin and hair intact. Yevgeny Salinder stumbled upon the extraordinarily well-preserved remains in the Taymyr tundra, a few miles away from the Sopkarga polar weather station, according to The Moscow News. After...

Mammoths and mastodons may have once roamed the Earth together, but they represent two distinct species of the Proboscidean family. And while these extinct giants have a lot in common, they also exhibit some interesting differences. Mammoths, belonging to the genus Mammuthus, arose about 5.1 million years ago in Africa,...

Updated at 7:30 a.m. ET on May 30. A frozen mammoth has been unearthed in the Siberian ice, and it contains perfectly preserved blood and tissue, according to a scientist in Siberia. The torso and gnawed-on legs of the mammoth were unearthed, along with dripping blood, in the frozen Novosibirsk...

Despite the recent discovery of a stunningly preserved mammoth, the odds of scientists using it to clone a real-life mammoth anytime soon are still low, experts say. To clone a mammoth by finding intact cells — and, more importantly, an intact genome — is going to be exceptionally difficult, likely...

Mammoth unearthed (Image credit: Semyon Grigoriev | North-Eastern Federal University in Yakutsk)In May 2013, researchers Semyon Grigoriev and colleagues at North-Eastern Federal University in Yakutsk recently unearthed an astonishingly well-preserved mammoth carcass on an island off the coast of Siberia. Fresh blood (Image credit: Semyon Grigoriev | North-Eastern Federal University...

A previously unknown European lineage of woolly mammoths once plodded Earth, suggest new DNA analyses, which also provide new evidence for the role of climate change in the animal's ultimate extinction. The woolly mammoth — an ancient relative of the Asian elephant — roamed northeastern regions of Siberia as far...

NEW YORK— De-extinction, the process of bringing saber-toothed tigers, woolly mammoths and other extinct animals back into the world, has become increasingly plausible with recent advancements in modern genomics research. What was once discussed only in the context of science-fiction plots has now become a conceivable reality. But as this...

Updated Tues. March 4 at 12:30 p.m. ET. The idea of bringing extinct species back to life has transitioned from science fiction to near reality in recent years, with some scientists saying the passenger pigeon — a bird that once clouded North American skies but went extinct due to over-hunting...

The last of the woolly mammoths may have suffered from high rates of devastating birth defects, new research suggests. Fossils of mammoths found near the North Sea and dating to the late Pleistocene, about 12,000 years ago, frequently sported extra ribs along their neck vertebrae. Though harmless on their own,...

The frightening last moments of two baby mammoths that died thousands of years ago are now being revealed, thanks to CT scanning. The 1- and 2-month-old woolly mammoth calves, which were discovered in different portions of Siberia, choked on mud after falling into water more than 40,000 years ago, new...

VANCOUVER — A fossil tusk rescued from the sea proves mammoths swam to Southern California's Channel Islands much earlier than thought. The new fossil is one of two recently discovered tusks that challenge the idea that climate change killed off the Channel Islands' pygmy mammoths, said Daniel Muhs, a geologist...

Mammoth bones more than 70,000 years old emerged from the eroded river banks of a reservoir in Idaho this month. Paleontologists and students raced to rescue part of the beast's skull and a tusk, but they suspect more lies below the surface, perhaps a full skeleton. [Read full story on...
