Late Maastrichtian pterosaurs from North Africa and mass extinction of Pterosauria at the Cretaceous-Paleogene boundary
Fig 18
Late Cretaceous pterosaur functional diversity.
Santonian-Campanian (blue) versus Maastrichtian (red) functional diversity, based on principal coordinates analysis of habitat, wingspan, jaw shape, and limb proportions (S2 Data). Axis 1 accounts for 54.4% of variation; axis 2, 11.2%; axis 3, 4.5%; axis 4, 3.0%, axis 5, 1.9%; axis 6, 1.4%; and axis 7, 1%.
