Closed-mouth vocalization might be present in some dinosaurs

A research paper posted online in the journal Evolution has unveiled that not every dinosaur roared ferociously. As per researchers, there were some dinosaurs that used to mumble or cooed with closed mouths.

In the study, the researchers have closely studied a way using which birds emit sounds known as closed-mouth vocalization. In order to understand when and as to how closed-mouth vocalization evolved, international researchers used a statistical approach.

Climate change pushed megafauna into extinction: research

Large mammals like sloths, saber-toothed cats, giant bears and mammoths lived in South America and went extinct around 12,000 years ago. Evolutionary biologists and ecologists believe that blame two possible culprits for the disappearance of those gigantic mammals.

One possibility is that those ancient large mammals went extinct because of the peopling of the Americas. Supporters of this theory believe that humans hunted the big animals to extinction.

Evidence from bison fossils helps scientists determine how first people migrated to Americas

Evidence from bison fossils helps scientists determine how first people migrated to Americas

With the help of evidence from bison fossils, scientists have found when an ice-free corridor opened up down the Rocky Mountains in the late Pleistocene. The corridor was considered a probable route through which humans and animals might had have migrated between the far north and the rest of North America, but when and how it was used isn’t known so far.

Combing the radiocarbon dating and DNA analysis, the researchers tracked the bison’s movements into the corridor, indicating that it was completely open by nearly 13,000 years back.

Archaeologists Produce State-Of-The-Art Scan of Ancient Art

A dramatic and state-of-the-art scan has been launched by archaeologists, depicting ancient rock paintings on the highest-ever altitude. The art has been discovered on a sandstone ceiling of a shelter located in the southern French Alps.

The new digital scans display the art in its real colors. The prehistoric art is located at an elevation of approximately 7,000 feet. The shelter where it is located is known as Abri Faravel, a small rock overhang, and is situated on a plateau in France.
