Giraffatitan ("giraffe titan") is a genus of sauropod dinosaurs which lived during the Upper Jurassic, about 140 million years ago. It was related to Brachiosaurus, and was one of the largest animals known to have walked the earth.
Giraffatitans were about 23-metre (75 ft) long and weighed about 40 tonnes (88,000 lb). They had very long necks and were well adapted for feeding on the tall conifers which were the main trees in the Jurassic forests. They lived in what is now Tanzania.
