Unveiling Japan's ancient practice of cranial modification: The case of the Hirota people in Tanegashima      (via sciencedaily.com)     Original source 

Cranial modification is a form of body alteration where the head is pressed or bound to permanently deform the skull. The practice has been reported across various cultures throughout history. Researchers report that the Hirota people -- who lived on the southern Japanese island of Tanegashima between the 3rd to 7th century CE -- also conducted cranial modification, with indication that both males and females performed the practice.

Using gemstones' unique characteristics to uncover ancient trade routes      (via sciencedaily.com)     Original source 

Gems' unique elemental composition and atomic orientation act as a fingerprint, enabling researchers to uncover the stones' past, and with it, historical trade routes. Scientists now employ three modern spectroscopic techniques to rapidly analyze gems found in the Arabian-Nubian Shield and compare them with similar gems from around the world. They have identified elements that influence gems' color, differentiated stones found within and outside the region, and distinguished natural from synthetic.

Family trees from the European Neolithic      (via sciencedaily.com)     Original source 

The Neolithic burial site of Gurgy 'les Noisats' in France revealed two unprecedentedly large family trees which allowed a Franco-German team to explore the social organization of the 6,700-year-old community. Based on multiple lines of evidence, the team describes a close kin group which practiced monogamy and female exogamy, and experienced generally stable times.

New archosaur species shows that precursor of dinosaurs and pterosaurs was armored      (via sciencedaily.com)     Original source 

Researchers have described a new species of armored reptile that lived near the time of the first appearance of dinosaurs. With bony plates on its backbone, this archosaur fossil reveals that armor was a boomerang trait in the story of dinosaur and pterosaur evolution: the group's ancestors were armored, but this characteristic was lost and then independently re-evolved multiple times later among specialized dinosaurs like ankylosaurs, stegosaurs, and others.

Missing island explains how endemic species on the Miyako Islands emerged      (via sciencedaily.com)     Original source 

Miyako Islands are home to various native species of snake and lizards. How these species came to call these islands home has long puzzled scientists. A group of researchers have compiled the latest geological and biological data, proposing that an island once facilitated migration between Okinawa and Miyako Islands.

Unusual fossil shows rare evidence of a mammal attacking a dinosaur      (via sciencedaily.com)     Original source 

Scientists have described an unusual fossil from around 125 million years ago in China that shows a dramatic moment in time when a carnivorous mammal attacked a larger plant-eating dinosaur. The two animals are locked in mortal combat, and it's among the first evidence to show actual predatory behavior by a mammal on a dinosaur. The fossil's presence challenges the view that dinosaurs had few threats from their mammal contemporaries during the Cretaceous, when dinosaurs were the dominant animals.

Fossils reveal how ancient birds molted their feathers -- which could help explain why ancestors of modern birds survived when all the other dinosaurs died      (via sciencedaily.com)     Original source 

Birds are the only group of dinosaurs that survived the asteroid-induced mass extinction 66 million years ago. But not all the birds alive at the time made it. Why the ancestors of modern birds lived while so many of their relatives died has been a mystery that paleontologists have been trying to solve for decades. Two new studies point to one possible factor: the differences between how modern birds and their ancient cousins molt their feathers.
