Measurements of lion skulls with FM stenosis (FMH< = 16.60 mm) and those with larger FM opening, comparing males and females separately.

Significantly different values in the same raw and within the same sex are marked with a superscript asterisk. FMH = foramen magnum height, BT = basilar thickness All comparisons were done using T-test: a t = 2.284, DF = 159, P = 0.024 b t = 3.630, DF = 120, P<0.001 c t = 1.339, DF = 72, P = 0.185 d t = 1.468, DF = 61, P = 0.147 e t = 3.283, DF = 265, P = 0.001 f t = 2.229, DF = 205, P = 0.027 g t = 1.826, DF = 192, P = 0.069 h t = 0.826, DF = 145, P = 0.410
