Tarbosaurus skeletal mount at the Mesa Southwest Museum. Photo Â© Geb Bennett. The theropod (meaning beast-footed) dinosaurs are a diverse group of bipedal saurischian dinosaurs. They include the largest terrestrial carnivores ever to have made the earth tremble.

Education Requirements. To gain an entry-level job in marine biology, you need to have a Bachelor of Science degree in marine biology or a related field such as biochemistry, biology, botany, ecology, microbiology or zoology.
If you want to be a marine biologist, you are preparing for a life in science. Science education in high school is a must. Nearly all school systems in the U. S. teach biology, chemistry, earth sciences, and physics. All are essential for an understanding of the natural world.
