This flying reptile lived in the Mesozoic era, in Jurassic, about 155-140 million years ago.
An adult copy was 5 cm in length, 10 g in weight and 50 cm in wings.
They populated forested areas near the waterside and was a great insect hunter, such as crickets and dragonflies. These were often caught in flight, clenched in sharp teeth and then swallowed.
Although the species was ranked long-tail flying dinosaurs, Anurognathus had a relatively short tail but perfect to give it mobility, flexibility and stability during flight, but also the ability to ignite the prey faster. It is the smallest flying dinosaur.
The head was robust, tall and short compared to body size, and the brain was sufficiently developed to give the animal the opportunity to coordinate with great precision movements during the flight. The mouth could be wide open, and the jaws were provided with many conical teeth, pointed, positioned at a certain distance from each other. The neck was short and thick, well inserted into the area between the head and the body.
The wings were long, and the big eyes looked like the dinosaur could be very good at dusk. As with other flying dinosaurs, the wings developed from the forelegs, the patch stretched from the last toe (the fourth from the forepaws), and the other three ended with sharp claws and had the role of hooking and clamping.
The patch was stretched perfectly to the ankle of the posterior limbs so that their paws remained free. This allowed the dinosaur to rest on the back of the paws and the big and bent claws, especially when he was resting or preparing to make a stunt to fly in flight.
Body weight of the anurognathus was greatly diminished by the fact that the bones were hollow inside and had very thin walls. Moreover, the bones had small holes that were connected to the air bags of the lungs.
This made good oxygen circulation, as well as a temperature balance in the muscle area during the flight. In flight, he was excellently leaning on the wind, but he moved slowly on the ground because of the muscles of the weakly developed posterior limbs.
Anurognathus Dinosaur’s Food
Some researchers support the idea that this insectivor also feeds on parasites on the skin of large-sized dinosaurs. Others, however, disagree with this idea because they believe the animal has a skull too short for this purpose.
