Dinosaur whose name means "thunder lizard" (12)

I believe the answer is:

brontosaurus

(Other definitions for brontosaurus that I've seen before include "Large herbivorous dinosaur" , "Huge herbivorous Jurassic reptile" , "Dinosaur with a long neck and tail" , "Prehistoric beast (thunder lizard)" , "Prehistoric thunderer?" .)

I've seen this clue in The New York Times.
