Living at the same time as the dinosaurs, Hesperornithiform bird fossils have been found in North America, Europe and Asia in rocks 65–95 million years old. Dr Alyssa Bell and Professor Luis Chiappe of the Dinosaur Institute, Natural History Museum of Los Angeles County, publishing in Journal of Systematic Palaeontology, have undertaken a detailed analysis of their evolution, showing that separate lineages (see Fig.1
