Fig. 3. Trace of a crouching theropod (left in the field). A. The crouching track comprises subparallel impressions of the metatarsus, two small, undetailed manus imprints, the imprints of the ischial callosity, the impression of the tail, and tracks from the dinosaur walking toward and away from the resting site. Upslope direction is to the right. Knivehandle is 10 cm long. B. Interpretative drawing of an unspecified small theropod dinosaur crouching down to produce the configuration of tracks seen in A. The manus posture during resting, where only the metacarpals are in contact with the ground producing an amorphous rounded depression is based on Weems (2006). The animal was progressing directly up the slope and was crouching facing upslope before it continued directly up the dune face.
