Pterosauria (Pterosaurs)

Abstract

Pterosaurs were a highly successful group of carnivorous reptiles with well‐developed wings and an excellent flight ability. They lived alongside the dinosaurs, survived for more than 140 million years and filled many habitats now occupied by birds and bats.

Keywords: pterosaurs; flight; jurassic; cretaceous; reptiles

Figure 1.

The evolutionary history of pterosaurs. Each column represents the known extent of a particular lineage with blank sections indicating gaps in the fossil record. Important fossil horizons are shown in italics and the figures on the left side indicate age in millions of years. Abbreviations: Alb, Albian; Ani, Anisian; Apt, Aptian; Bar, Barremian; Baj, Bajocian; Bat, Bathonian; Ber, Berriasian; Cal, Callovian; Cam, Campanian; Car, Carnian; Cen, Cenomanian; Hau, Hauterivian; Het, Hettangian; Kim, Kimmeridgian; Lad, Ladinian; Maa, Maastrichtian; Nor, Norian; Oxf, Oxfordian; San, Santonian; Sin, Sinemurian; Toa, Toarcian; Tth, Tithonian; Val, Valanginian.

Figure 2.

The skeleton of Rhamphorhynchus (wingspan, 1 m). Wing‐membranes and some of their internal fibres are shown on the left side. Abbreviations: ch, cheiropatagium; f, fibres; h, humerus; i, ii, iii, digits one to three; or, orbit; p, pelvis; pr, propatagium; sh, shoulder girdle; sk, skull; st, sternum; t, tail; up, uropatagium; v, fifth toe; wf, wing‐finger.
