The Rhamphorhynchus (Rhamphorhynchus muensteri) is a pterosaur in the Rhamphorhynchidae family of long-tailed pterosaurs in the Jurassic period. Rhamphorhynchus means beak snout. It is a cousin of the dinosaurs, and it is believed to be among the first flying vertebrates.
It had a long tail that ended with a soft tail vane. It had needle-like teeth that were angled forward. It also had a curved, sharp, beak-like tip that lacked teeth. From a study of its teeth and stomach contents, palaeontologists think that its diet was mainly fish and cuttlefish.

The Epidexipteryx (Epidexipteryx hui) is a small pterosaur, a cousin of the dinosaur, in the Scansorioptergidae family.
Palaeontologists found a partial skeleton, which was from the Middle Jurassic or Upper Jurassic period.
It had four long tail feathers with central, unbranched rachis (spines) and vanes. Modern birds have branched vanes. It also had simpler body feathers than modern-day birds. It had teeth, but only in the front of the jaw, with long front teeth angled forward.

The Archaeopteryx (Archaeopteryx lithographica) is a small pterosaur, a cousin of the dinosaur, in the Archaeopterygidae family. Archaeopteryx means ancient wings.
Palaeontologists think it was the oldest known bird that was on the Earth. It lived in the Late Jurassic period around 150 million years ago in the land that it now called Europe.
