Dinosaurs are a varied group of animals from taxonomic, morphological and ecological standpoints. Birds, at over 10,000 living species,[3] are the most diverse group of vertebrates besides perciform fish.[4] Using fossil evidence, paleontologists have identified over 500 distinct genera[5] and more than 1,000 different species of non-avian dinosaurs.[6] Dinosaurs are represented on every continent by both extant species and fossil remains.[7] Some are herbivorous, others carnivorous. While dinosaurs were ancestrally bipedal, many extinct groups included
