APPENDIX 2

New characters and coding changes

296. Ischium, ventral margin: (0) continuous ventral margin; (1) abrupt change in angle between the proximal end and the shaft. (Modified from Nesbitt 2011)

The character state 1 defined by Nesbitt (2011) as a notch present in the ventral margin of the ischium is here considered independent of the angle of said margin, and therefore the presence or absence of a notch or incision is proposed as a separate character (char. 421)

416. Dentary, ratio of length to basal height of ventral angular process: (0) equal or more than 1.5, (1) less than 1.5 (New)

417. Proximal ends of chevrons: (0) with two separate articular heads, (1) both articular facets connected by a bony bar, so that a closed haemal canal is present (New)

418. Scapula-coracoid suture, posterior margin: (0) entire margin, (1) presence of an oval incision on the coracoid (Desojo and Rauhut 2008)

419. Ischium, dorsolateral margin: (0) smooth, (1) with longitudinal depression delimited medially by a ridge (Modified from Desojo and Rauhut 2008)

420. Ischium, position of longitudinal depression: (0) dorsal, (1) lateral.

Inapplicable for those without longitudinal depression (New)

421. Ischium, ventral margin: (0) continuous, (1) obturator plate separated from the ischial shaft by a small incision (Desojo and Rauhut 2008)

422. Fibula, “lunate” fossa on posteromedial surface of the distal end: (0) absent, (1) present (New)
