Fig. 7 in Crouching theropod and Navahopus sauropodomorph tracks from the Early Jurassic Navajo Sandstone of USA

Fig. 7. Comparisons between the manual and pedal skeleton of sauropodomorph material from the Navajo Sandstone of northern Arizona and the Navahopus coyoteensis isp. nov. trackway from Coyote Buttes. The skeletal material was originally referred to as Ammosaurus (Galton 1971), but has recently been revised and reinterpreted as belonging to an indeterminate sauropodomorph (Yates 2004). A. The manus of the sauropodomorph from northern Arizona is tridactyl and consists of two short, forward−facing digits (II and III) and the large pollex claw of digit I directed inward. The pes is tetradactyl with digits III and IV of subequal length, followed by the shorter digits II and I; modified from Baird (1980). B. Manus and pes couple from N. coyoteensis. Note the close correspondence between the pedal skeleton and the tracks, here shown to the same scale.

Fig. 3 in Crouching theropod and Navahopus sauropodomorph tracks from the Early Jurassic Navajo Sandstone of USA

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.

Fig. 6 in Crouching theropod and Navahopus sauropodomorph tracks from the Early Jurassic Navajo Sandstone of USA

Fig. 6. The ichnofamily Navahopodidae, characterized by the tridactyl manus impression with the prominent inward directed pollex trace. A. Navahopus falcipollex Baird, 1980, the holotype MNA P3.339 from the collection of the Museum of Northern Arizona, Flagstaff. B. Baird's (1980) interpretation of Navahopus falcipollex as a sauropodomorph trackway, with an enlarged medially directed pollex claw. C. New interpretative drawing of Navahopus falcipollex, with less pronounced pollex impressions, and suggested mammal affinities. From Lockley and Hunt (1995). D. Sketch of Navahopus coyoteensis isp. nov. manus and pes couplets from left and right side of the trackway. In the pes prints, digits III and IV are separated by a deep hypex, recognizable in all well−preserved tracks in the trackway. All manus prints in the new trackway show consistent impressions of a large, medially directed pollex claw, supporting the original interpretation of Baird (1980), that Navahopus was made by a sauropodomorph dinosaur. Compare with Fig. 7. E. New interpretation of Tetrasauropus unguiferus Ellenberger, 1972 from the Lower Stormberg assemblage of Southern Africa (Porchetti and Nicosa 2007).

Fig. 5. Sketch of the trackway in figure 4. The sketch is redrawn from high−resolution digital photographs of the trackway. RM, right manus; LM, left manus; RP, right pes; LP, left pes. The solid arrow indicates the direction of progression and the broken−line arrow the orientation of the body during progression. Notice how the animal walked at an oblique angle upslope in the first half of the trackway, and then changed to progress head on, up the slope.
