MESSAGES IN STONE Produced and directed by John Robichaud Prehistoric Productions, 1993. VHS cassette, 52 min., $149.00. Distributed by T.H.A. Media Distributors. Marsha Kaiserman Volume 22 Number 44 1994 September Dinosaurs are probably one of the most fascinating subjects there is. Young and old, we rush to museums to view the dinosaur displays. Our knowledge of dinosaurs and their time on Earth is limited and, as a result, our imaginations run wild. We know, in general, how dinosaurs must have looked, but are we right in our guesses? How many of us are familiar with more than two or three species of dinosaurs? Messages in Stone is a video about a recently discovered dinosaur called Pachyrhinosaurus. Using a combination of stop-motion animation and live video, we see how Pachyrhinosaurus was born, lived, died and was ultimately discovered. Following researchers of the Royal Tyrell Museum of Paleontology in Drumheller, Alberta, we travel to Dinosaur Provincial Park, where Pachyrhinosaurus was found. We follow the fossil from excavation to restoration in the laboratory, to the making of the cast and models and, finally, the display of the full-scale model. It is a fascinating and exciting trip. While Pachyrhinosaurus is the real star of this video, he has a strong supporting cast. Leslie Nielsen is the host, providing the narration, while world-renowned paleontologists Phillip Currie, Dale Russell, Robert Bakker and Jack Horner provide the scientific background and expertise. These are interesting people with a passion for dinosaurs. Perhaps the most exciting moment in this video occurs when each one of these experts provides a different theory as to why dinosaurs became extinct. Produced and directed by John Robichaud and written by John and Gerry Robichaud, Messages in Stone is an entertaining, exciting and fascinating video that must be seen. Highly recommended.
