Ceratopsians and other marginocephalians were highly abundant animals. They represent about one-quarter of the dinosaur taxa discovered from the latest Cretaceous Period. Together with the iguanodontian ornithopods, these dinosaurs successfully displaced sauropods as the dominant large herbivores in the Northern Hemisphere. Like the success of the ornithopods during the same time, marginocephalians may have succeeded where sauropods failed in adapting to the consumption of a more diverse vegetarian diet that included both tough-skinned gymnosperms and the softer flowering plants that were rapidly spreading during the Late Cretaceous.
Segnosaurus ursoides is a bear-shaped descendant of the original dinosaur Segnosaurus. This was an animal with the general outline of the prosauropod dinosaurs, such as plateosaurus, but with massive bearlike claws on the forelimbs. S. ursoides has exaggerated these trends, being bulkier by far, with larger claws, and with a neck and tail of only moderate length. It is one of the closest dinosaur counterparts to a true bear there is. Perhaps a ground sloth would be a better comparison, though, as this creature is a pure vegetarian like that animal, using its huge claws not only for self-defense, but also for digging up the tree roots that
In all probability, almost every dinosaur, even those considered vegetarians, were in actuality omnivores at some point in their lives, certainly when they were in the rapid growth stages and possibly also during periods of egg production. You may question how we arrived at that conclusion, but even today characterizing an animal as an herbivore, omnivore, or carnivore is an almost impossible task, so we assume the same held true for dinosaurs. Few vertebrates are truly one or the other. For example, mammals begin their lives dependent on a food source rich in protein, mother's milk. Fruit- and nectar-eating birds feed bugs to their young, and because many insectivorous birds take fruits and seeds as well, most birds would be considered omnivores.133 So both mammals and birds start life eating animal proteins, and although some go on to become herbivores as adults, overall they could be classified as omnivores. Since some paleontologists consider birds living dinosaurs, the principle...
