Scope and Terminology
There is no official, canonical list of pterosaur genera, but the most thorough attempts can be found at the Pterosauria section of Mikko Haaramo's Phylogeny Archive, the Genus Index at Mike Hanson's The Pterosauria, supplemented by the Pterosaur Species List, and in the fourth supplement of Donald F. Glut's Dinosaurs: The Encyclopedia series.

Famous quotes containing the word scope:
“As the creative adult needs to toy with ideas, the child, to form his ideas, needs toys—and plenty of leisure and scope to play with them as he likes, and not just the way adults think proper. This is why he must be given this freedom for his play to be successful and truly serve him well.”
—Bruno Bettelheim (20th century)
