For 150 million years, the skies didn't belong to birds--they belonged to the pterosaurs.
These flying reptiles, which include the pterodactyls, shared the world with the nonavian …

The tectonics, geography and climate of the Cretaceous world were very different from the
modern world. At the start of the Cretaceous, the supercontinent of Pangaea had just begun …

North-south provinciality among Campanian and/or Maastrichtian vertebrates, especially
dinosaurs, in the Western Interior basin of North America (specifically, between West Texas …

There is a long tradition of indirectly inferring feeding in fossil and Recent vertebrates from
the functional morphology of bones and teeth. However, some trace fossils provide direct …

Pterosaurs were the first vertebrates to evolve powered flight and the largest animals to ever
take wing. The pterosaurs persisted for over 150 million years before disappearing at the …

Despite the attention focused on mass extinction events in the fossil record, patterns of
extinction in the dominant group of marine vertebrates—fishes—remain largely unexplored …

The size and flight mechanics of giant pterosaurs have received considerable research
interest for the last century but are confused by conflicting interpretations of pterosaur …

Although viviparity (live-bearing reproduction) is widely distributed among lizards and
snakes, it is entirely absent from other extant Reptilia and many extinct forms. However …

Viviparity is known in several clades of Mesozoic aquatic reptiles, but evidence for it is
lacking in the Plesiosauria. Here, we report a Late Cretaceous plesiosaur fossil consisting of …

Pterosaurs, the first vertebrates to evolve powered flight, dominated Mesozoic skies from the
Late Triassic to the end Cretaceous, a span of around 154 Myr (∼ 220–66 Ma). They …
