Anurognathus ("Without Tail Jaw") is a genus of small, carnivorous, diminutive, rhamphorhynchoid pterosaur that originated during the Late Jurassic-Early Cretaceous period in what is now both Germany and North America.


Era & DiscoveryEdit

Anurognathus lived during the Late Jurassic Period and the Early Cretaceous Period from 154–130 million years ago. Anurognathus was first named and described by Ludwig Döderlein in 1923.

Physical AttributesEdit

Anurognathus was one of the smallest pterosaurs, having a tiny wingspan of about 30–50 centimeters in length - very small indeed by Pterosaur standards, even for Rhamphorhynchids.

In spite of being within this suborder, Anurognathus had a short head with pin-like teeth, and its tail was comparatively short, uncharacteristic of the group (which are largely notable for their long tails), allowing it more maneuverability for hunting in the woodland. It would have weighed less than a bag of sugar, a kilogram or less.

Behavior & TraitsEdit

Anurognathus lived in very large, swarm-like flocks and groups, and were predators of devastating savagery. Anurognathus attacked prey in their large numbers and used their needle-like teeth to attack their prey and strip the flesh away in moments. Anurognathus could also smell blood across considerably large distances, like piranhas, and were drawn to it very easily.

As a tiny flying reptile, Anurognathus was a pterosaur that specialized in life among giant dinosaurs, even ones as large as the massive sauropods. These pterosaurs fed on insects and spent their entire lives hanging on to sauropods. They fought, fed, and bred on creatures that were over 150 thousand times heavier than they are. Because of their small size, Anurognathus was near the bottom of the food chain. However, Anurognathus would usually be safe from predators as it was a nocturnal, somewhat bat-like insectivore.
