No single person “discovered dinosaurs,” but a few key scientists are usually credited with turning strange old bones into what we now recognize as dinosaurs.

Early fossil finders

Long before anyone knew what dinosaurs were, people were digging up their bones without understanding them.

  • In 1677, English naturalist Robert Plot described a giant thighbone (later recognized as from Megalosaurus) but thought it belonged to a huge human or other large creature, not an extinct reptile.
  • For centuries, similar large bones were treated as curiosities, sometimes linked to mythical giants or dragons rather than to a distinct group of ancient animals.

First correctly identified dinosaur

The first person generally credited with correctly identifying a dinosaur fossil was William Buckland , an Oxford geology professor.

  • In 1824, Buckland studied bones from quarries near Stonesfield in England and named the animal Megalosaurus , meaning “great lizard,” recognizing it as a large, extinct, carnivorous reptile.
  • Buckland did not yet realize that Megalosaurus belonged to an entirely new group that would later be called dinosaurs, but his work is considered the first modern scientific description of a dinosaur.

Naming “dinosaurs” as a group

The word “dinosaur” itself came a bit later, from the British anatomist Sir Richard Owen.

  • In 1841–1842, Owen compared fossils of Megalosaurus , Iguanodon , and Hylaeosaurus and recognized that they formed a distinct group of large, extinct, reptile-like animals, which he named Dinosauria , meaning “terrible lizards.”
  • Because of this, Owen is often said to have “discovered dinosaurs” in the sense of defining them as a unique scientific group, even though he built on fossils described by earlier researchers.

Why there isn’t one discoverer

Modern understanding of dinosaurs grew step by step, rather than from one eureka moment.

  • Early observers like Plot found the bones, Buckland gave the first clear scientific description and species name, and Owen created the concept and name “Dinosauria.”
  • Later in the 1800s, intense fossil hunting “dinosaur rushes” in Europe and North America added many more species, turning dinosaurs into one of the most studied and famous groups of extinct animals.
