 Dubbed "Duria Antiquior — A more Ancient Dorset", this watercolor painting represents a scene from the Early Jurassic of Dorset, a fossil-rich region of the British Isles.This painting, based on fossil discoveries along the coast of Dorset by paleontologist Mary Anning, showcased realistic aspects of fossil animal appearance, behavior, and environment at a level of detail, realism and accuracy that was among the very first of its kind.This watercolor, an early illustration of paleoecology, shows plesiosaurs and ichthyosaurs swimming and foraging in a natural setting, and includes depictions of behavior of these marine reptiles that, while unknown, were inferences made by De la Beche based on the behavior of living animals.
