Figure 16. Tarsometatarsi of (B–G) fossil Megalurus sp. compared with the corresponding bones of (A) M. timoriensis AM O.65209 and (H) M. cruralis AM O.59220 in dorsal view. (B) QM F57934, left tarsometatarsus; (C) QM F30360, proximal left; (D) QM F57936, distal left; (E) QM F57937, distal left; (F) QM F30375, distal right; (G) QM F57935, distal left. Some distinguishing features labelled as follows: 1, impressio lig. collateralis medialis at about level with arcus extensorius; 2, lateral foramen vasculare proximale large; 3, tuberositas m. tibialis cranialis located distally adjacent of arcus extensorius and medially of shaft midpoint; 4, foramen vasculare distale situated proximally of incisura intertrochlearis lateralis by distance of ≥ 2× length of tr IV; 5, tr II similar width to tr III; 6, incisura intertrochlearis medialis narrow; 7, medial rim of tr II greater in distal and dorsal extents than lateral rim; 8, distal edge of tr IV at disto-lateral angle to shaft long axis. Arrows indicate different extent of medial protrusion of trochlea metatarsi II. Scale = 2 mm.
