T. rex's serrated, cone-shaped teeth were most likely used to pierce and grip flesh. Its two-fingered forearms could probably seize prey, but they were too short to reach its mouth. Scientists believe this powerful predator could eat up to 500 pounds (230 kilograms) of meat in one bite.
Angles and distances are measured from the total station to points under survey, and the coordinates (X, Y, and Z or easting, northing and elevation) of surveyed points relative to the total station position are calculated using trigonometry and triangulation.
Total Stations. Total stations are one of the most common surveying tools used today. They comprise of an electronic theodolite and an electronic distance metre/measurement (EDM) component. Robotic total stations are also available which allow for single-person operation by controlling the instrument using a remote control. History
