Abstract

Abstract: The structure of Mesozoic vegetation is outlined as consisting of evergreen brachyphyllous forests, deciduous forests dominated by Phoenicopsis and then by Parataxodium, cycadophyte—sclerophyllous shrublands and fern marshes. Warm, warm-temperate and temperate zones are indicated for successive periods. Dinosaur localities are situated mostly in the warm and warm-temperate zones but a few of them fall in the temperate zone. Feeding habits of dinosaurs are inferred from combined evidence of depositional environments, surrounding vegetation and stomach contents. It is suggested that dinosaurs were associated mainly with open vegetation, such as shrublands and marshes, capable of supporting large populations of herbivores. The shrubland and marsh dinosaur communities are provisionally indicated, the latter comprising diplodocids, stegosaurs and hadrosaurids. Replacements of dinosaur communities were concomitant with major vegetational changes. Forestation at the end of Cretaceous time might have played an important role in the final extinction.
