Engineering technology reveals eating habits of giant dinosaurs
Date:7/16/2012

High-tech technology, traditionally usually used to design racing cars and aeroplanes, has helped researchers to understand how plant-eating dinosaurs fed 150 million years ago.

A team of international researchers, led by the University of Bristol and the Natural History Museum, used CT scans and biomechanical modelling to show that Diplodocus - one of the largest dinosaurs ever discovered had a skull adapted to strip leaves from tree branches.

The research is published today [16 July] in leading international natural sciences journal, Naturwissenschaften.

The Diplodocus is a sauropod from the Jurassic Period and one of the longest animals to have lived on Earth, measuring over 30 metres in length and weighing around 15 tonnes.

While known to be massive herbivores, there has been great debate about exactly how they ate such large quantities of plants. The aberrant Diplodocus, with its long snout and protruding peg-like teeth restricted to the very front of its mouth, has been the centre of such controversy.

To solve the mystery, a 3D model of a complete Diplodocus skull was created using data from a CT scan. This model was then biomechanically analysed to test three feeding behaviours using finite element analysis (FEA).

FEA is widely used, from designing aeroplanes to orthopaedic implants. It revealed the various stresses and strains acting on the Diplodocus' skull during feeding to determine whether the skull or teeth would break under certain conditions.

The team that made this discovery was led by Dr Emily Rayfield of Bristol University's School of Earth Sciences and Dr Paul Barrett of The Natural History Museum in London. Dr Mark Young, a former student working at both institutions, ran the analyses during his PhD.

Dr Young said: "Sauropod dinosaurs, like Diplodocus, were so weird and different from living animals that there is no animal w
