The Project

Adventurous artists Sylvia Causer and Sheila Wetton have teamed up with biologist Dr Gavin Thomas to highlight the plight of endangered species and the price we all pay when biodiversity is threatened.

As well knowing a thing or two about biodiversity, Gavin is the curator of the University’s Alfred Denny Zoological Museum, a treasure trove of weird and wonderful specimens, including some creatures you may never have heard of.

With Gavin as their expert guide, Sylvia and Sheila embarked on a project of painstaking detail, learning the science of bone, feathers and fur to produce a series of 30 closely observed drawings. These astonishing artworks bring rarely seen animals and birds to vivid life.
