50K-year-old juvenile mammoth carcass discovered in Russia's thawing permafrost

(Newser) - Russian scientists have unveiled what they say is the best-preserved mammoth carcass ever discovered—that of a juvenile dubbed "Yana." The female mammoth, believed to have been about a year old when she died an estimated 50,000 years ago, was discovered this summer in thawing permafrost in...

Dinosaur Dung, Vomit Offers Clues to Their Rise

As opportunistic eaters, they were well-suited to environmental change, researchers say

(Newser) - Much attention has been paid to the question of what killed the dinosaurs. But how did they arise in the first place? And how did they come to dominate the planet? A new 10-year analysis of dinosaur poop moves us closer to the answers, per CNN . Paleontologist Martin Qvarnström...

Hiker's Find Leads to Trove of Fossils Predating Dinosaurs

Hundreds of imprints of plants, animals, even raindrops discovered in northern Italian Alps

(Newser) - Claudia Steffensen was hiking in the Italian Alps last summer when she stepped on a rock that caught her eye. "It seemed more like a slab of cement" with "these strange circular designs with wavy lines," Steffensen tells the Guardian. "I took a closer look and...

In Prehistoric Fossils, a Surprising Find on Aging

Mouselike mammals lived a lot longer than modern-day counterparts, say scientists

(Newser) - Two sets of fossils found 40-something years apart suggest that small mammals who lived during the mid-Jurassic period had a longer "childhood" and a more stretched-out life span than their contemporary counterparts. The new research published Wednesday in the journal Nature examined the fossilized remains of Krusatodon kirtlingtonensis, a...

New Dinosaur Species Named After Norse God

Lokiceratops had massive, blade-like horns

(Newser) - A dinosaur that researchers say is new to science has been named after the Norse god Loki not because of any mischievous tendencies, but because of its massive, blade-like horns. In a study published in the journal PeerJ , researchers say Lokiceratops rangiformis was one of many ancestors of Triceratops that...

Scientists Find Evidence of 'Age of Monotremes'

A diversity of platypus-like creatures roamed Australia some 100M years ago

(Newser) - There are exactly five existing egg-laying mammals, or monotremes: the platypus and four echidna species, all native to Australia and New Guinea. According to new research, they're the last survivors of a diverse set of species that roamed the southern continents during the time of the dinosaurs. The Lightning...

Ichthyotitan severnensis estimated at 82 feet long, with a 7-foot-long jawbone

(Newser) - It was the largest reptile to ever prowl Earth's oceans. At some 82 feet, this giant ichthyosaur would've been nearly as large as a blue whale, a marine mammal and the largest animal known to exist at any point in the planet's history. Yet the ichthyosaur, dubbed...

New caenagnathid species, and a possible second, suggest this dino family was doing fine

(Newser) - Paleontologists have been debating whether the asteroid that killed non-avian dinosaurs took out a varied group of thriving reptiles or one already in decline . Now, researchers say they've discovered a new dinosaur species whose very existence disputes the latter argument. The argument is largely based on apparent declines in...

Fossilized sample predating the dinosaurs represents oldest epidermis ever found

(Newser) - It looks a lot like crocodile skin, with a pebblelike texture someone might desire for a purse. But for the small sample size, you'd never guess it's 289 million years old, dating to the late Paleozoic Era, when many species were just beginning to venture from water to...

'We're Pretty Sure It's Not a Bird'

But what made bird-like tracks before birds existed isn't clear

(Newser) - The earliest known fossils attributed to ancestors of modern birds date to around 160 million years ago, which is why birdlike tracks discovered in southern Africa and dated to tens of millions of years earlier have become a fascinating topic of discussion for paleontologists. In reviewing 163 tracks found across...

Cat-sized 'Lumakoala' could be marsupials' missing link in Australia's Northern Territory

(Newser) - The modern koala is a well-known and well-loved marsupial, but researchers know surprisingly little about its evolution. Indeed, they describe an "approximately 30-million-year-gap" in the fossil record of Australian marsupials, or diprotodontians, a group including kangaroos, wallabies, and wombats. That gap may be closing, however. Researchers say they've...

Rhynchosaurs had a single set of teeth they wore down to nubs, may have starved to death in old age

(Newser) - In the age before the towering dinosaurs we know so well from textbooks and Jurassic Park movies, an ugly-cute creature about the size of a pig called the rhynchosaur roamed the Earth, chomping on tough plants with a single row of teeth. As the New York Times reports, they were...

M. sinocanadorum had a 50-foot-long neck, made up of mostly hollow vertebrae: study

(Newser) - Think giraffes have long necks? Paleontologists say a dinosaur that roamed northwest China some 162 million years ago had a neck eight times as long, making it the "longest-known neck in the animal kingdom," per IFL Science . Partial remains of the dinosaur, Mamenchisaurus sinocanadorum, were discovered in the...

Study suggests ancient plesiosaurs lived in freshwater bodies of water, though not Loch Ness

(Newser) - A new study offering some of the best evidence yet for ancient long-necked reptiles living in freshwater lakes has been seized upon by believers in the Loch Ness Monster. Plesiosaurs, small-headed beasts with flippers that disappeared from the fossil record 66 million years ago, certainly inhabited Earth's oceans. There...

Paleontologist Calls Gorgosaurus Sale a 'Disaster'

Rare skeleton was sold for $6.1M

(Newser) - A rare and exquisite Gorgosaurus skeleton sold for $6.1 million at a Sotheby's auction in New York City Thursday—but since the anonymous buyer apparently wasn't a museum or an unusually wealthy paleontologist, scientists say they find the sale concerning. Gorgosaurus was a distant—and faster—relative...
