The scientific genus name for a specific type of long-necked dinosaur that lived during the Jurassic period and had front legs longer than its back legs.
From Greek 'brachion' (arm) and 'sauros' (lizard), with the Latin genus ending '-us'. This formal taxonomic name was established in the 1900s when paleontologist Elmer Riggs discovered and classified the species.
Brachiosaurus is probably the dinosaur most people picture when they think 'big dinosaur,' and it deserves the title—at 85 feet long and 80 tons, it was basically the blue whale of the dinosaur world, except it lived on land and had to support all that weight on four legs.
