People used to hunt dinosaurs. Dinosaurs died out 65 million years ago. Indians who lived in America before Columbus were members of the same tribe of simple people. Prior to European contact, the Americas were inhabited by hundreds of well-developed cultural groups with distinct and mutually unintelligible languages. The houses, tools, foods, and other aspects of life differed among these populations because they lived in different environments and met basic needs in culturally unique ways.
Archaeologists dig up dinosaurs.
Paleontologists study the fossil remains of extinct animals, including dinosaurs, and geologists study rocks. Archaeologists study people of the past through their material remains. Archaeologists spend all of their time digging. Archaeology is more than a dig. Archaeologists actually spend a relatively small amount of their time excavating, compared to the time spent in the laboratory, analyzing and interpreting their finds, and preparing written reports about the project.
