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.
The following are some of the major advantages of using total station over the conventional surveying instruments: 1  Field work is carried out very fast. 2  Accuracy of measurement is high. 3  Manual errors involved in reading and recording are eliminated. 4  Calculation of coordinates is very fast and accurate.
