Not every ancient reptile is a dinosaur: how to spot the difference
In short: Many prehistoric creatures are mistaken for dinosaurs, but the distinction is precise. Museum scientist Matt Porter explains the biological criteria that define a true dinosaur, while highlighting other remarkable animals like pterosaurs and plesiosaurs that coexisted with them millions of years ago.
The Natural History Museum in London houses over 80 million objects, ranging from meteorites to giant squid. While dinosaurs are a major focus, the museum's collection includes many other ancient reptiles that are often confused with them. This video, originally broadcast on 23 October 2020, clarifies the classification of these prehistoric animals.
True dinosaurs are distinct from other reptiles that lived during the same era. For instance, flying pterosaurs and sea-faring plesiosaurs are frequently grouped with dinosaurs in popular culture, yet they belong to different evolutionary branches. Understanding these distinctions helps clarify the diverse range of life that once inhabited the Earth.
