sauro-, saur-, -saurus, -saurid, -saur,
-sauria, -saurian +

(Greek: lizard, reptile, serpent; used especially with reference to "dinosaurs")

Aachenosaurus was found and named in 1888, by the scientist Gerard Smets who named the species Aachenosaurus multidens, to what was believed to be two hadrosaurian (duck-billed dinosaur) fragments. Later that year the specimens proved to be pieces of petrified wood.

Smets at first tried to defend his original identification, but he was proven to be wrong by a neutral commission and so it is reported that he withdrew from scientific research completely because of his humiliation or mortification.

Dinosaur expressing itself with a BROOM sound.

Dinosaurs came in all shapes and sizes and many of the "scientific" conceptions about them are essentially guesswork or estimations.
