Scientists found a 9-million-year-old capybara relative’s tooth in Chile’s Atacama Desert, one of Earth’s driest places; the water-loving animal adds evidence that the region once supported wetlands and a much wetter climate

Scientists found a 9-million-year-old capybara relative's tooth in Chile's Atacama Desert, one of Earth's driest places; the water-loving animal adds evidence that the region once supported wetlands and a much wetter climate

The newly discovered tooth provides another reason to reconsider how the region looked in the distant past, the report claims. The Atacama Desert is a landscape where water is measured in millimetres, not rivers. Today, parts of this vast Chilean desert receive almost no rain, making the discovery of an animal that depended on plentiful … Read more

T. rex had a body temperature of 36.3°C, almost the same as humans; fossil tooth chemistry reveals the 66-million-year-old predator was warm-blooded and could survive in cold climates

T. rex had a body temperature of 36.3°C, almost the same as humans; fossil tooth chemistry reveals the 66-million-year-old predator was warm-blooded and could survive in cold climates

Representative Image via Canva For 66 million years, the body temperature of Tyrannosaurus rex (T.rex) lived only in speculation. Now, a new study has taken the dinosaur’s temperature using chemistry locked inside its fossilised teeth, finding an average of about 36.3°C (97.3°F), strikingly close to the human norm. The researchpublished in Science Advances, offers one … Read more

A narwhal can grow a single 10-feet tooth through its upper lip; scientists used 3D X-rays and 3 particle accelerators to discover how nature’s only straight tusk stays straight

A narwhal can grow a single 10-feet tooth through its upper lip; scientists used 3D X-rays and 3 particle accelerators to discover how nature's only straight tusk stays straight

An international team of biologists, chemists and physicists has used sophisticated 3D X-ray technology to investigate the tooth at an unprecedented level. A unicorn may be a mythical creature, but nature made something very similar under the Arctic ice. Wondering what? Well, the narwhal has a strange tusk that can reach nearly 10 feet long … Read more
