Bird beak revealed by laser imaging informs early beak function and development

Confuciusornis was a crow-like fossil bird that lived in the Cretaceous ~120 million years ago. It was one of the first birds to evolve a beak. Early beak evolution remains understudied. Using an imaging technique called Laser-Stimulated Fluorescence, researchers address this by revealing just how different the beak and jaw of Confuciusornis were compared to birds we see today.

Ancient human footprints in Saudi Arabia give glimpse of Arabian ecology 120000 years ago

Using high resolution paleoecological information obtained from fossilized footprints, a new study presents ~120 thousand-year-old human and animal footprints from an ancient lake bed in northern Arabia. These findings represent the earliest evidence for humans in this part of the world and show that human and animal movements and landscape use were closely linked.
