Death of the megabeasts

University of Exeter scientist Dr Tim Barrows has recently appeared as an expert on past climate change in the National Geographic Channel production ‘Death of the Megabeasts’.

A team of experts were assembled for the production to tackle the controversial issue of what caused the extinction of the Australian megafauna; a collection of giant marsupials, reptiles and birds. Given this happened more than 40,000 years ago, the evidence is sparse. But new records of past climate change are hinting that climate was not responsible, and the finger is now pointing towards the impact of the arrival of humans.

For an overview of the programme and to watch some clips for the programme visit the National Geographic website.

A series of extinctions also occurred in the British Isles. Tim Barrows’ third year module are investigating how these are dated. The class recently attended a field trip to Kents Cavern in Torquay and a short article appeared in the Herald Express.
