Figure 8. A, a strict consensus tree of the 124 most parsimonious trees found by the analysis of the modified version of Sereno's (1999) data matrix. B, a 50% majority-rule consensus tree based on the 12 reduced consensus topologies produced by re-analysis of the modified Sereno (1999) data matrix. 'Gripposaurus' represents a referred individual of 'Gyposaurus' sinensis (Young, 1948); material included as 'Sellosaurus' is currently regarded as Efraasia (Yates, 2003b).
