Primary quantitative analysis of 108 pterosaur taxa. It documents an every-continent record while emphasizing severe spatial and temporal patchiness and sampling-sensitive biogeographic inference.
Pterosaur remains are reported from every continent, but a 108-taxon analysis finds the record extremely patchy; package dossiers therefore remain tied to named specimens and localities rather than a complete distribution.
