Dicraeosaurus (hansemanni, sattleri )
Name means: Bifurcated/Double-forked lizard
Period: Late Jurassic (155-150 MYA)
Length: 41 ft (12 M)
Weight: 10 tons

This diplodocoid dinosaur, whose first fossil was discovered by Werner Janensch in 1914, actually possesses characteristics that differ from typical diplodocids. The first difference to be noted is the lack of a whiplike tail, a chief characteristic of diplodocids.

Dicraeosaurus also had a relatively short neck that consisted of 12 vertebrae. These vertebrae had large, Y-shaped spines growing from them, hence this dinosaur’s name. Due to the shortness of Diceaeosaurus’ neck, it is believed that this sauropod dined on low lying vegetation. It is thought that the maximum height of grazing was 9.8 ft (3 M).

Dicraeosaurus fossils have been discovered in Tendagaru Hill in Tanzania, which shows that this dinosaur preferred woodland areas. Dinosaurs like Kentrosaurus and Giraffatitan have also been discovered at this location, but it is believed that they co-existed peacefully due to differing browsing heights.

This sauropod is closely related to Armagasaurus (a sauropod that I will cover in the future).
