New computer simulations suggest they used river valleys like natural highways to cross daunting landscapes during warmer climate windows. These findings not only help solve a long-standing archaeological mystery but also point to the likelihood of encounters and interbreeding with other ancient human species like the Denisovans.

Thanks to new research, scientists believe that these creatures are 14 million years older than previously thought. The new age -- dating back to 346 million years ago -- adds to the significance of the find because it places the specimens in a mysterious hole in the fossil record called Romer's Gap.

Scientists reveal that a recently identified second species of bacteria responsible for leprosy, Mycobacterium lepromatosis, has been infecting humans in the Americas for at least 1,000 years, several centuries before the Europeans arrived.

Named Traskasaura sandrae, this 85-million-year-old marine reptile sported a freakishly long neck, crushing teeth, and bizarre shoulders that baffled paleontologists for years. It appears to have been a top-tier predator that hunted prey from above — a novel strategy among plesiosaurs. Its discovery not only clears up a decades-long puzzle but also gifts the Pacific Northwest with a uniquely strange Mesozoic creature to call its own.
