Fig 6. Inferred nest type for six extinct archosaurs as a function of Pagel's lambda values.

Inferred nest type is generally consistent across all lambda values, except for oviraptorosaurs where inferred nest type changes when the lambda value varies between 0.08 and 0.52, and for titanosaurs and Lourinhanosaurus, which change to open nesters when lambda values approach one. The yellow line indicates the optimal lambda value (0.56).
