文摘

In light of diverse geological evidence that indicates a seasonal, semiarid climate for the time of deposition of the Morrison Formation, one can assume these general environmental conditions for the purpose of reconstructing the ancient ecosystem. Wet environments that preserved plant fossils and some invertebrates and small vertebrates in the Morrison can be interpreted as representing local conditions limited in space and/or time. These elements of the biota and the smaller dinosaurs were probably restricted to such wetland areas at times of environmental stress.
