Scientists have reconstructed the skull of an Ichthyornis dispar, a very early bird species that still had the sharp teeth of a dinosaur
It was one of the fossils Darwin hailed as evidence of evolution. Now scientists have unveiled four skulls of an ancient toothed seabird in a study experts say reveals the face of early birds.
Thought to have lived between 66 and 100m years ago the gull-like bird, known as Ichthyornis dispar, was first written about in the 19th century by American palaeontologist Othniel Marsh after fossil remains were unearthed in the US.
