Answer:

D

Explanation: Preparation revealed five types of trace fossils on the bone surfaces--shallow pits; rosettes; hemispherical pits; thin, curvilinear grooves; and U- to V-shaped grooves. Trace fossils, also called ichnofossils, do not contain information about the organism itself. Rather, they contain information on traces left by the organism. Common examples of trace fossils include burrows, nests, footprints, dung and tooth marks.
