Etymology
The name "brontosaur" is a modern scientific Latin construct from the late 19th century, directly pieced together from classical Greek roots. It was coined by the American paleontologist Othniel Charles Marsh in 1879. The literal meaning, "thunder lizard", was intended to evoke the immense size and presumably earth-shaking footsteps of this colossal dinosaur. This naming follows a common pattern in paleontology, where Greek roots are combined to create descriptive, evocative names for prehistoric creatures, with the "thunder" element purely metaphorical to convey power and magnitude.
Analysis

- bronto: From Greek brontē (βροντή), meaning "thunder". Functions as a descriptive prefix in the compound.
- saur: From Greek sauros (σαῦρος), meaning "lizard" or "reptile". Functions as the core noun root.
