|Scientists are probing the remains of two Ice Age puppies found perfectly preserved in Russia's far northeast region of Yakutia and dating back 12,460 years. The mummified dogs were found by hunters searching for mammoth tusks in a riverbank by a deposit of ancient bones in remote Arctic tundra. As they explored the area, they found a puppy's snout in the permafrost. |
The second puppy was found a few feet away. The dogs both died when they were about three months old and were likely siblings. It's unclear if the Ice Age dogs were domesticated or wild.
|The find could offer clues about the origin of domesticated dogs. The world's oldest dog remains were discovered in a cave in Belgium. They were 36,500 years old, but weren't well preserved.|

|Scientists in Brazil found an ancient 250-million-year-old beast that they have named Teyujagua paradoxa. Fossil remains of the previously unknown species of reptile were found in the Brazilian state of Rio Grande do Sul. It is an important find because it is a link between ancient reptiles and the creatures that would eventually become dinosaurs and then birds and crocodiles.|
This skull reveals for the first time the mosaic assembly of key features of the archosauriform skull.
|The fossil was found in an area of exposed Triassic rock, and it would have lived not long after a massive volcanic eruption in eastern Russia eliminated 90 percent of living species. The reptile - and its close relatives the archosauriforms - became the dominant animals on land and eventually gave rise to the dinosaurs.|
Teyujagua paradoxa are transitional in morphology between archosauriforms and more primitive reptiles.
|Teyujagua paradoxa was a small, quadrupedal reptile. The species grew up to about 5 feet (1.5 m) in length and lived in the margins of lakes and rivers, hunting amphibians and procolophonids — extinct, small bodied reptiles similar to lizards.|
Its teeth were recurved with fine serrations and sharply pointed, indicating a carnivorous diet.

|They ruled the oceans for more than 157 million years; dolphin-like marine reptiles called ichthyosaurs. Science learned of ichthyosaurs’ existence early in the nineteenth century with the discovery of the first complete skeleton in England. The order Ichthyosauria (Greek for fish-lizard) was named in 1834.|
|The mystery surrounding their extinction 66 million years ago towards the end of the Cretaceous period (30 million years prior to the global dinosaur extinction) has prompted many theories. Newly published research suggests the fate of ichthyosaurs was tied to climate change.|
|Strong fluctuations in temperatures and sea levels 100 million to 94 million years ago during the Cenomanian stage of the Cretaceous period coinciding with intense volcanic action, ice-free poles, rapidly shifting continents and periods of anoxia (a lack of oxygen) on the sea floor affected a large portion of the marine biosphere and significantly changed marine ecosystems.|
Ichthyosaurs were unable to successfully evolve new species in response to their quickly changing world.

|British archaeologists have unearthed the remains of a previously unknown Anglo-Saxon island, located in the village of Little Carlton, near Louth, Lincolnshire.|
Once home to a Middle Saxon settlement, many intriguing items emerged from the field. The items include another 20 styli, about 300 dress pins, a huge number of “sceattas” – coins from the 7th-8th centuries – and a small lead tablet bearing the female Anglo-Saxon name, Cudberg.
|It is thought the settlement might have been an island monastery or a trading center. Using geophysical and magnetometry surveys along with 3D modelling, the researchers digitally restored the water level of the island to its higher medieval state.|
It was connected to the outside world through waterways.
|The presence of coins from various parts of mainland Europe offered evidence of commerce with Germany, Scandinavia and the Low Countries.|
Loom weights unearthed by archaeologists indicated that the Anglo-Saxons may have exported woven textiles while importing pottery and wine.
