The Dust Bowl of the 1930’s refers to a large section of prairie land subjected to severe ecological damage resulting from farmers using a deep plowing method on the thin soil. The uprooted grass holding the topsoil together was further eroded by a series of droughts and eventually blew away as massive dust storms.

Triceratops - During the late Cretaceous period, triceratops, Greek for “three-horned face,” appeared and spread over much of North America. It was the largest and heaviest of the ceratopsians. Triceratops shared its environment with tyrannosaurus and was heavily armed with two enormous brow horns and a smaller nose horn. The estimated length of a triceratops was 8 or 9 meters and its height was about 3 meters. It became extinct through an asteroid impacting the earth during the Cretaceous–Paleogene extinction event.
