Figure 6.5
Scene in Early Bathonian times, showing a small lake in Gloucestershire surrounded by seed ferns and conifers. Fishes (Lepidotus) live in the water, and frogs (Eodiscoglossus) disport themselves around the sides. Dinosaurs include some of the earliest stegosaurs and maniraptorans (?), plated and small carnivorous dinosaurs respectively. A carcass of the large sauropod, Cetiosaurus, is rotting in the water, and Megalosaurus scavenges. Lizard-like animals, crocodiles, pterosaurs, mammals and tritylodont mammal-like reptiles complete the scene. Based on a restoration painting by Pam Baldaro, showing the scene at Hornsleasow Quarry, Gloucestershire. Reproduced with permission of the University of Bristol.
