10:44 PM | Portage Chute
Churchill River, Manitoba: August 24, 2014 Heading south from Churchill, the helicopter follows the river for the first 30 kilometres above its mouth. Then we head off overland, taking a straight-line shortcut instead of duplicating the river’s long dogleg. “Overland” is, perhaps, a bit of a misnomer, since the surface we pass over must be at least […]

10:36 PM | 3D Images Provide New Insights into Biology of Dodo
Using 3D laser surface scans of two skeletons of the dodo, paleontologists have reconstructed how this famous extinct bird lived, looked, and behaved. The dodo (Raphus cucullatus) is an extinct flightless bird that lived on the island of Mauritius in the Indian Ocean. The bird was first discovered by European sailors in 1598, and was [...]

3:19 AM | Armored Dinosaurs Had Elaborate Nasal Passages
Since paleontologists began using CT scans and 3D reconstructions of dinosaur remains, they have been able to tell us much more about dinosaurs than ever before.Ankylosaur skull(William Diller Matthew, US PD)Now a new study shows that armor-plated dinosaurs (ankylosaurs) had the capacity to modify the temperature of the air they breathed using nasal passages shaped like "crazy straws."We know that animals use strategies such as sweating, panting, and swimming to prevent their brains from […]

6:27 PM | 9,300-Year-Old Frozen Steppe Bison Found in Siberia
Paleontologists have discovered a well-preserved frozen mummy of the extinct Steppe bison (Bison priscus) on the shore of Chukchalakh Lake in Yakutia, Siberia. The Yukagir bison mummy, as the find was dubbed, has a complete brain, heart, blood vessels and digestive system, although some organs have shrunk significantly over time. “It is a male about [...]

An international team of paleontologists headed by Marco Marzola from the New University of Lisbon, Portugal, has discovered nearly 70 fossilized tracks of dinosaurs, prehistoric mammals and crocodiles in the large diamond mine Catoca in northeast Angola. All the tracks were found in a small sedimentary basin that formed in the crater of a kimberlite [...]

1:30 PM | How To Determine The Color Of The Ancient Archaeopteryx Wing
Reconstructing ancient life has long required a certain amount of inference and imagination - especially speculative is the coloration of long-extinct organisms. New methods of investigation are being incorporated into paleontology that may shed light (and color) on fossils. read more

1:30 AM | Frozen Extinct Bison Found in Siberia
Many large mammals went extinct at the end of the last Ice Age (approx 11,000 years ago), including the Steppe bison, or Bison priscus. A team of scientists has found one of these extinct bison frozen and naturally mummified in Eastern Siberia. It's a complete specimen frozen in time.A Steppe bison on display at the University of Alaska Museum of the North(Bernt Rostad from Oslo, Norway, via Wikimedia Commons)According to the research team, they have uncovered the most complete frozen […]

7:25 PM | Complete Frozen Bison Mummy From 7,000 B.C. Found In Siberia
Many large mammals went extinct at the end of the most recent Ice Age (about 11,000 years ago), including the Steppe bison, Bison priscus. Recently an intact one was found, literally frozen in time. This most complete frozen mummy of the Steppe bison yet discovered dates to 9,300 years ago and was uncovered in the Yana-Indigirka Lowland.  The Yukagir bison mummy, as it is named, has a complete brain, heart, blood vessels and digestive system, although some organs have shrunk […]

3:09 PM | Ancient Horse Fossil Contains Unborn Foal
A fossil of the ancient horse Eurohippus messelensis found in Germany contains a fetus as well as parts of the uterus and associated tissues. Eurohippus messelensis had four toes on each forefoot and three toes on each the hind foot, and it was about the size of a modern fox terrier. Though different in size and structure, reproduction in early horses was very similar to that of modern horses. The new find was unveiled at the 2014 Annual Meeting of the Society of Vertebrate Paleontology in […]

11:26 AM | First Amphibious Ichthyosaur Found – Cartorhynchus lenticarpus
Paleontologists led by Prof Ryosuke Motani of the University of California, Davis, have discovered an amphibious ichthyosaur that lived in the seas of what is now China during the upper Lower Triassic, about 248 million years ago. The discovery is the first to link the dolphin-like ichthyosaur to its terrestrial ancestors, filling a gap in [...]

3:25 AM | Madagascar: Fossil Offers Clues to Evolution of Mammals
About 70 million years ago, in the heyday of the dinosaurs, a groundhog-like mammal lived on the island of Madagascar. Weighing an estimated 20 pounds (9 kg), it was the largest mammal of its time.This image is a finite element analysis result, showing how stress is distributed through the skull under an incisor bite at a wide gape angle. (UMass Amherst)The mammal is named Vintana sertichi. Its fossilized skull was found in a geological formation that was deposited when a great variety of […]

A team of paleontologists led by Prof David Krause of Stony Brook University has discovered a groundhog-like animal that lived in what is now Madagascar during the Late Cretaceous epoch, about 70-66 million years ago. The new fossil mammal, named Vintana sertichi, belongs to Gondwanatheria (or gondwanatherians), a group of early mammals that lived during [...]

3:55 AM | Digital Dinosaurs: Paleontologists Use New Technology to Digitally Restore a Dinosaur Fossil
Fossils are usually crushed or incomplete when they are found. Millions of years can take a toll, after all. Consequently, fossils have to be studied very carefully to avoid damage and sometimes they are hard to access. Now, an international team of scientists has found a better way to examine delicate fossils and reconstruct their original forms. An artist's rendition of Erlikosaurus, depicted with feathers(Arthur Weasley)The team has been using high-resolution X-ray computed tomography […]

3:03 PM | Zaraapelta nomadis: New Armored Dinosaur Discovered in Mongolia
Paleontologists have discovered a new genus and species of ankylosaur that roamed what is now the Gobi Desert in Mongolia during the Upper Cretaceous, between 100.5 and 66 million years ago. The new dinosaur is named Zaraapelta nomadis. It belongs to Ankylosauridae, a family of herbivorous dinosaurs with armored plates on their back. The genus [...]

We had just listened to a series of presentations, […]

Carlos Manduga lives in the resort city of Mar del Plata, Argentina, which lies about 250 miles south of the country’s capital Buenos Aires. Not too long ago, Manduga was digging and cleaning out a well on his property when he came across the fossilized remains of a pre-historic creature. Manduga found a skull, ribs, a number of vertebrae and a few other fossilized remains. Manduga immediately contacted the Lorenzo Scaglia Natural History Museum to inform them of the find. […]

4:00 PM | Oldest Modern Genome From Human Bone Reveals When We Bred With Neanderthals
The femur that led to the oldest modern human genome. Credit: Bence Viola, MPI EVABy Daniel Zadik, University of LeicesterWhen a human bone was found on a gravelly riverbank by a bone-carver who was searching for mammoth ivory, little did he know it would provide the oldest modern-human genome yet sequenced. The anatomically modern male thigh-bone, found near the town of Ust’-Ishim in south-western Siberia, has been radiocarbon-dated to around 45,000 years old. read more

9:30 PM | The world's oldest genome shows when our ancestors had sex with Neanderthals.
The world's oldest genome shows when our ancestors had sex with Neanderthals. Analysis of a 45,000 year-old femur shows that modern humans and Neanderthals mated 52,000 to 58,000 years ago — a much smaller window than previously estimated (a 49,000 year span). It's the oldest-known human genome ever sequenced, revealing a mysterious population that once spanned northern Asia. Read more...
