Episode 7: Colouration in fossils

We can observe colour to be highly important for animals today. It can be used for many different purposes, including camouflage and signalling, and produced by many different methods. What is true of colouration today is also likely to have been so in the past, however the fossilisation process replaces tissues with minerals, so finding hints of colour in fossils is very unlikely. There are however certain colour producing structures that can survive the fossilisation process. We visit the University of Bristol to talk to Maria McNamara, a post-doctoral research assistant, to learn more about the preservation of colour in the fossil record.
