The Wikipedia article of the day for December 9, 2018 is Brachiosaurus.
Brachiosaurus (from Greek for “arm lizard”) was a sauropod dinosaur that lived in what is now North America during the Late Jurassic, about 154–153 million years ago. The genus was first described by American paleontologist Elmer S. Riggs in 1903 from fossils found in the Colorado River valley in western Colorado. Only a few other specimens of Brachiosaurus are known to exist, making it one of the rarer sauropods of the Morrison Formation. It was probably between 18 and 21 meters (59 and 69 ft) long; weight estimates range from 28.3 to 58 metric tons (31.2 to 63.9 short tons). Like other sauropods, it was a large dinosaur with a long neck and small skull; atypically, it had longer forelimbs than hindlimbs, a steeply inclined trunk, and a proportionally shorter tail. It was a high browser, possibly cropping or nipping vegetation up to 9 meters (30 ft) off the ground. Initially thought to be one of the largest dinosaurs, Brachiosaurus appeared in the 1993 film Jurassic Park.
