A. Luoyang shovel(铲) —This tool was invented in China. It has a half－cylindrical(半圆形的) shape with the help of an extended rod(延长杆) and an attached rope. Archaeologists(考古学家) shove it in the ground and then pull it up to do some surveys.
B. Brushes—To avoid breaking artifacts while excavating, great care must be taken. A variety of brushes are used to remove the dirt from around the artifacts. Stiff brushes are used to remove larger material, while softer ones help remove finer material.
C. Drones—They can take pictures and videos of a whole site, which is quite useful in many ways. Before digging, it gives a wider view of a whole site and allows archaeologists to see things clearly from ground level. during the digging process, it can take low-altitude(低空的) and vertical(垂直的) shots quickly, which makes it easier to map the remains later.
D. Compasses—Archaeologists usually work in the wild. They use a compass to tell direction.
E. Tape measure—Tape measures are used to make sure that the size of each unit in a dig site and the depth of each level are as exact as possible.
F. Watering cans—When the ground is dry, it's hard to draw line in the soil to create units. Archaeologists use watering cans to sprinkle(喷洒)water on the ground to keep the soil wet.
