Centrosaurus (Planet of Dinosaurs)

Centrosaurus is the main antagonist in the Planet of Dinosaurs.

History
Horribly awesome sci-fi trash from 1978. During the ascent, Nyla (Pamela Bottaro) slips and loses the entire supply of food rations, which Lee refuses to retrieve. Near a cave higher up the mountain, Vice-President of Spaceways Incorporated Harvey Baylor (Harvey Shain) discovers a nest full of eggs. After stealing an egg, Harvey is attacked and killed by a Centrosaurus. Soon after, much to ship engineer Jim's (James Whitworth) dismay, Lee decides to halt the expedition and settle at what he considers to be a defensible area. Lee expects to hold out until they are rescued, but Jim believes them to be trapped forever on the planet, and advises that they begin a new civilization. Even though that dinosaur killed a guy, it still runs like a Schnauzer. Captain Lee and his crew crash land on a  planet  similar to Earth, but millions of years behind in time. Wow..Loved the way Centrosaurus came out from behind the rock..Check out Labib's talks on dinosaurs.
