"Scientists already knew that birds evolved from dinosaurs. But thanks to a Yale-led study published Wednesday in the https://www.nature.com/articles/s41586-018-0053-y" rel="nofollow - journal Nature , they know what the first bird beak (næb) looked like during that evolutionary journey. The beak belongs to an Ichthyornis dispar from about 85 million years ago. The beak was small, and appeared at the end of its jaw filled with teeth. At its origin, the beak was a precision grasping mechanism that served as a surrogate hand as the hands transformed into wings This half-bird, half-dinosaur was a seabird similar in size to a gull (måge)."
