German name for frill-necked lizard?
The Chlamydosaurus kingii is called "Die Kragenechse" in German.
"Brontosaurus" means thunder lizard. However, the name Brontosaurus is an invalid dinosaur name. The name Brontosaurus arose from the misidentification of another dinosaur, Apatosaurus. So, technically, Brontosaurus did not even exist, but its name does mean thunder lizard which I believe comes from the Latin word "tonitrus".
