Plots showing the relationship between the anteroposterior length of the surangular foramen and the skull length (as a proxy of body size) in tyrannosaurids.Bagaraatan ostromi was measured for the single (posterior only) or double (posterior + anterior) foramina. A, regression analysis including all specimens shows a negative slope and a high correlation coefficient. B, regression analysis for specific taxa shows the same trend. No distinction between small, medium, or large size of the surangular foramen can be noticed in the tyrannosaurids.	Figure 22.

Asterisks indicate the posterior surangular foramen.Note that the placement of the double surangular foramina in B.ostromi is similar to the enlarged posterior surangular foramen in Ta.bataar. During ontogeny, the surangular shelf faces more laterally and the glenoid becomes longer anteroposteriorly.	Figure 5.
