The Rise of the Ornithopods

Описание: Having first evolved during the Middle Jurassic as small, fast running herbivores, the Ornithopods began to develop larger body sizes by the end of the period. Equipped with highly efficient jaws and tightly packed teeth for processing plant matter, the group diversified rapidly going into the Cretaceous, possibly taking advantage of the Tithonian extinction event as well as the rise of flowering plants. This set the stage for the expansion of the Hadrosauroids during the second half of the Cretaceous.
