That of specimens Cio and Hio curves slightly forwards, but that of K37 curves slightly backwards (Fig. 5). The dorsal surface of this process bears a pattern of longitudinal grooves similar to that found on the ribs of the more anterior dorsal vertebrae (Fig. 8). There is no trace of a suture between the neural arch and this process, which may therefore be either a transverse process or a co-ossified rib. The zygapophyses of this tenth dorsal vertebra are rather wide. Sacral vertebra (Fig. 6). Specimen H (the natural mould) contains the only example of a sacral vertebra, which is preserved as part of an articulated series of vertebrae extending as far posteriorly as the second caudal. Only the ventral regions of this vertebra are preserved in the mould, but this includes the whole of the sacral.
