Definition: Hesperornithoid is a group of birds that have feathers and claws and are part of the family Arctoidea. The name "hesperornithoid" comes from the Greek word "hesperus," meaning "stern," which refers to the sharp, pointed beak and the long, curved wingtips of these birds. These birds were found in Europe, Asia, and Africa during the Late Cretaceous period, around 65 million years ago. H
