LFGT-0103 probably represents a sub-adult individual, as indicated by the relatively small body size of the specimen, the large orbit, the lack of fusion between the scapula and coracoid, the lack of ossification of distal tips of the ischia, and the separation of the astragalus and calcaneum. However, the neurocentral sutures are fused, cervical ribs are fused to their respective centra, the ilium is fused to the ischium, and distal tarsal 3 is probably fused to metatarsal III, indicating that the specimen may be close to an adult individual.

Most of the lateral surface of the right maxilla is exposed. The rostral process of the maxilla and the rostrodorsal edge of the maxillary body proper (the portion between the rostral process of the maxilla and the rostral rim of the internal antorbital fenestra, but not including the ascending process) have been lost, and the preserved rostrodorsal margin appears to represent the caudoventral rim of the external naris.

Caudodorsal to this ridge an elliptical fenestra opens laterally, while rostroventral to it are two small fenestrae separated by another short vertical ridge: a rostrally positioned fenestra that is more or less round in lateral view, and a caudally positioned one that is triangular.

The centrum of the third cervical is about 130% longer than that of the axis. Centrum lengths continue increasing steadily until cervical 7, then decrease gradually so that the last cervical is about equal in centrum length to the third one. All postaxial cervicals are elongate, with mid-central constrictions and stout prezygapophyses. The lateral surfaces of the centra of cervicals 4-5 bear deep, elongate pneumatic foramina (“pleurocoels) (

The third cervical rib has a small capitulum and tuberculum. In contrast, the remaining cervical ribs have well-developed capitula and tubercula, and are fused to their corresponding vertebrae.

). The femoral head is enlarged, well offset from the shaft, and directed craniomedially, with its end turned slightly downward. In proximal view, no clear constriction is apparent, and the proximal surface tapers caudolaterally. A longitudinal bulge is present near the proximal end of the caudolateral surface of the shaft. The anterior trochanter begins at the level of the ventral edge of this bulge, centered transversely on the craniolateral surface of the femur, as a prominent boss that extends ventrally. A tubercle lying caudal to the ventral end of the anterior trochanter may be homologous to the trochanteric shelf. The area proximal to the anterior trochanter is shallowly depressed.

). In proximal view, they combine to form a flat and roughly square articular surface for the femur. The cnemial crest forms the craniolateral corner of this surface, while the craniomedial corner consists of two small tubercles of the tibia that protrude slightly above the surface. The shafts of both the tibia and fibula are straight, and the fibula is closely appressed to the lateral surface of the tibia. The distal ends of both bones are enlarged.

). The proximal end of metatarsal IV is positioned slightly distal and dorsal to that of metatarsal III, indicating that the latter incorporates a fused distal tarsal III. The proximal end of metatarsal III extends ventrally well beyond the metatarsal shaft, and bears a clear ventrolateral process. The proximal surface of metatarsal IV has a triangular shape matching that of distal tarsal IV, with an expanded dorsal portion and a tapering ventral end. The fifth metatarsal is splint-like, with a proximal end at the same level as that of metatarsal III and a distal end that tapers abruptly to a point. The four phalanges of pedal digit III are preserved, as are the proximal three phalanges of pedal digit IV (
