| Abstract: | In the paper, the moving directions and scopes of cyrtograptus in sea are discussed, and it is pointed out that the sway tendency of cyrtograptus'young branches is related to the direction of paleosea current. Using the average values of the angles between the young and primary branches, to determine the paleosea current direction in the Middle Silurian Period is of actual significance in the exploration of mineral resource distribution. |
