KK: /ˈbrɒntəˌsɔr/
A large, long-necked dinosaur that lived during the late Jurassic period, often characterized by its massive size and herbivorous diet.
The brontosaur was one of the largest dinosaurs to roam the Earth.
Brontosaur is formed from "bronto-" (from Greek "brontē", meaning thunder) and "saur" (from Greek "sauros", meaning lizard or reptile). The word refers to a large dinosaur that was once thought to be a giant lizard associated with thunder due to its size.
Imagine a giant 'lizard' ('saur') that makes a 'thunder' sound ('bronto-') as it moves — that's how you can remember that a brontosaur is a massive dinosaur.
