Display screen with an animated graphical user interface

FIG. 1 is a front view of an display screen with an animated graphical user interface showing my new design;

FIG. 2 is a front view of a second image thereof;

FIG. 3 is a front view of a third image thereof;

FIG. 4 is a front view of a fourth image thereof; and,

FIG. 5 is a front view of a fifth image thereof.

The appearance of the transitional image sequentially transitions between the images shown in FIGS. 1 through 5 . The process or period in which one image transitions to another image forms no part of the claimed design.

In the drawings, the broken lines are for the purpose of illustrating portions of an display screen with an animated graphical user interface and an environmental mobile device that forms no part of the claimed design.
