BOLTON Museum is taking visitors on a trip back to prehistoric times with a display of dinosaur models.

The scale models, which measure from 15 centimentres to over half-a-metre in length, have gone on display after work by staff to restore them to their glory.

The 17 creatures are the work of Vernon Edwards who created them to be used in photographs in the first ever public science book dedicated to dinosaurs -- W.E. Swinton's The Dinosaurs: A Short History of a Great Group of Extinct Reptiles -- in 1934. Bosses at the museum hope the display will give an insight into how science has changed to give a different view on dinosaurs. The models in the museum will be presented with a 1934 interpretation and a 2004 interpretation to show how science has changed.

To help shed some light on changing views and the lives of these extinct reptiles, resident dinosaur expert, David Craven, will be giving a talk on Friday.

The event, starting at 1.30pm, is free and will give visitors the chance to ask any questions about dinosaurs.
