Laser scan based digital files of the tail and tail tip osteoderms of the MFN mount (scale bar 0.5 m). a In dorsal view with the anterior half of the tail at 10° lateral flexion per intervertebral joint, and the distal half in ONP. b With the sacrum in left lateral view at 2.5° extension per intervertebral joint. c In left lateral view at 5° extension per intervertebral joint. Light grey area marks a semi-circle covering the entire tail length, as described as the position in the field by Hennig (1913, 1925), and as suggested to represent the opisthotonic posture. Length of gap at the tail end between caudal 29 and distal caudals according to Janensch (1925)
