This striking specimen is Mammuthus jeffersoni, photographed by @jmsuarez_ #InsideAMNH. Mammoths were widespread during the Ice Ages, and some had woolly fur to keep warm. This “nonwoolly” mammoth lived about 11,000 years ago in the southern parts of the United States which were not covered by glaciers.

It’s a mammoth of a Fossil Friday! Mammuthus jeffersoni lived about 11,000 years ago and was collected in 1909 in Grant County, Indiana.  Mammoths were widespread during the Ice Ages. Some had woolly fur to keep warm. This “nonwoolly” mammoth lived in the southern parts of the United States which were not covered by glaciers. The only obvious difference between Mammuthus and the living Indian elephant is that the mammoth is much larger. Most mammoths died out by about 11,000 years ago, but a few somewhat dwarfed forms persisted until about 3,000 years ago, on remote arctic islands.  This fossil is located in the Museum’s Paul and Irma Milstein Hall of Advanced Mammals

Sasha: A baby woolly rhino

The gently thawing Siberian permafrost is famous for its finds of well preserved frozen mammoths (see and, but last summer, the Sakha Republic saw the first discovery of a baby rhino eroding out of a riverbank. Research has not yet properly started, but an international team is assembling to probe every aspect of this unique find, from anatomy to genetics in the hope of deepening our understanding of its relationship to modern rhinos.

She was named after the hunter who spotted her hair hanging out of the riverbank, spotted the horns sticking out of the jaw and alerted scientists at the Mammoth Fauna Department of the Yakutian Academy of Sciences. Her age at death is estimated at roughly 18 months, and they estimate that she is over 10,000 years old (the age of the youngest fossil ever found), but further tests are needed for confirmation. The results are due in about 6 months, though DNA analysis should be available sooner.

So far only five specimens of well preserved adult rhinos have been found throughout Europe and northern Asia, though fossil bones are more common. Sasha is the first ever juvenile, which will give researchers insights into their growth process and how it compares with that of their modern cousins. Much less is known about these large furry creatures that shared the ice age landscapes of Europe with our ancestors than their cousins the mammoths, though as the second photo (taken in Chauvet the oldest painted cave in France, dated to 32,000 years ago) reveals, our distant forebears certainly interacted with them.

Siberian Mammoth Unearthed After Eaten by People 25,000 Years Ago

Researchers in Siberia have found the remains of a baby mammoth that researchers believe was caught and eaten by humans about 25,000 years ago, local media reported Thursday.

The remains, discovered on the shores of Siberia’s Belaya River, were separated into at least three distinct groups of chopped ribs, a broken skull and other bones, and teeth — all stacked over a 1.5-square-meter area, leading researchers at the Irkutsk State University to hypothesize that the animal fell prey to hunters, the Babr news agency reported.

Researchers estimate that the bones, discovered earlier this month, are about 25,000 years old. Read more.
