Description

In February 2000, at the same time as excavating his property in St. George, Utah, Sheldon Johnson turned over a piece of ground and came upon an absolutely preserved dinosaur footprint. That track was once the first of many fossils to be uncovered. Five years later, the St. George Dinosaur Discovery Website at Johnson Farm was once established to preserve one of the vital richest and oldest dinosaur-age fossil sites in Utah.

Tracks in Deep Time presents, for the first time, an engaging, thoroughly readable account of the history, geology, and paleontology of this important Website. Two hundred million years ago, Lake Dixie covered the Website. Within its waters and along its shores, a diverse ecosystem of dinosaurs, early crocodylians, fishes, plants, and other organisms thrived, leaving in the back of thousands of footprints and other fossils preserved in layers of rock. Strange fossils found here include the world’s largest number of tracks left by swimming dinosaurs and one in every of only six traces known to have been made by a sitting, meat-eating dinosaur. With approachable text and lavish, full-color photographs and illustrations, Jerald Harris and Andrew Milner describe how geologists and paleontologists have painstakingly reconstructed a vivid “snapshot” of life from the Early Jurassic epoch.
