..Kicking up a cloud of dirt, a herd of Chasmosaurus marches towards a new land with plenty of fresh vegetation. In the shade of a tree, a Parasaurolophus sees off this seasonal migration, which is repeated every year.

..Just like the migration of gnus of present age, no one could ever have stopped such a crowd of herbivorous animals, once they started striding for fresh food.

..Other dinosaurs scramble away from the path of the armada to yield. A Stegoceras with bulky head, an Edmontonia under the supposed invincible thick arms, and a Troodon, a small-sized predatory dinosaur, all take refuge under the shade of magnolia trees. A Quetzalcoatlus floats sedately in the sky far away.

..----- About 70 million years ago (during the late Campanian and the early Maastrichtian), there may have been a scene like this illustration in the western part of ancient North American Continent.

..Sometimes, hundreds of fossils of the same species of dinosaurs are produced in the mass in the formations that show remains of flooded plain. Especially, it is known that there are outstanding examples of ceratopsians found in the formations of the Late Cretaceous in the North American Continent. Based on these facts, it is considered possible that some of ceratopsians, Chasmosaurus for example, lived and migrated a great distance in groups looking for grassy plains, just like gnus in Africa and reindeers in the north pole area do today.

..When crossing a river, hundreds of unfortunate members of the group were drowned and later fossilized, but they were only a small part of the group, ---- and it means there must have been at least thousands of survivors, who proceeded the migration. Dietary for supporting such an immense number of lives may have been assorted ground vegetation abundantly sprouting here, there and everywhere.

..Anyway, just like herding of gnus would fascinate photographers today, a troop of ceratopsians is one of attractive themes for paleontologic illustrations.
