description Anurognathus ammoni Overview
Anurognathus ammoni is a small pterosaur from the Late Jurassic Solnhofen Limestone of Bavaria, Germany, first described by Ferdinand Broili in 1923. With an estimated wingspan of only 35-40 centimeters, it represents one of the smallest known pterosaurs. Its anatomy is distinguished by an unusually short, broad skull measuring about 6 centimeters in length—giving it a frog-like appearance that inspired its generic name, meaning 'without tail jaw.' The structure of its jaws and teeth suggests it was an insectivore, likely catching prey on the wing similar to modern nocturnal insectivorous birds.
help Anurognathus ammoni FAQ
Where was Anurognathus ammoni discovered?
It comes from the Late Jurassic Solnhofen Limestone of Bavaria, Germany. That finely layered limestone is famous for preserving delicate flying reptiles and other small animals.
How large was Anurognathus ammoni?
It was exceptionally small for a pterosaur, with an estimated wingspan of about 35 to 40 centimeters. Its compact body and short tail made it quite different from long-tailed pterosaurs such as Rhamphorhynchus.
What did Anurognathus ammoni probably eat?
Its broad skull, numerous small teeth, and small size are consistent with an insect-eating lifestyle. It may have hunted flying insects around the islands and lagoons represented by the Solnhofen deposits.
Why is Anurognathus ammoni important in pterosaur evolution?
It shows that pterosaurs evolved very small, specialized forms as well as large soaring species. Its unusual short-faced, short-tailed anatomy makes it a distinctive member of the Late Jurassic pterosaur record.
