hadrosaur etymology

Etymology

Hadrosaur is derived from the Greek words:

• hadros (ἁδρός): meaning "thick" or "stout"
• sauros (σαῦρος): meaning "lizard"

Meaning

Hadrosaur means "thick lizard," referring to the bulky and sturdy nature of these dinosaurs.

Origin

The term "hadrosaur" was first coined by the German paleontologist Otto Hermann von Meyer in 1862. He originally classified hadrosaurs as a subfamily of Iguanodontidae, a group of herbivorous dinosaurs. In 1902, the American paleontologist John B. Hatcher established the family Hadrosauridae, which included all known hadrosaurs.

Origin of Hadrosaurs

Hadrosaurs evolved from a group of ornithopods called hadrosauroids during the Late Cretaceous period, around 80 million years ago. They became extinct along with other non-avian dinosaurs at the end of the Cretaceous period, about 66 million years ago.
