Measurement (length): Titanosaur
The Problem
The picture opposite shows what scientists think the complete skeleton of a titanosaur might have looked like.
From this picture, and from the fossilised titanosaur femur (thigh) bone featured in the clip, can you calculate the approximate length of this mighty dinosaur?
Did you know?
Despite their huge body size, the eggs of a titanosaur were very small. They were laid in nests on the ground and were covered with layers of vegetation and dirt (to stop other dinosaurs from finding and eating them).
