The
Anurognathidae were a group of small
pterosaurs, with short tails or tailless, that lived in
Europe,
Asia, and possibly
North America during the
Jurassic period. Four genera are known:
Anurognathus, from the
Late Jurassic of
Germany,
Jeholopterus, from the
Middle to Late Jurassic of
China,
Dendrorhynchoides, from the Middle Jurassic of China, and
Batrachognathus, from the Late Jurassic of
Kazakhstan. Bennett (2007) claimed that the
holotype of
Mesadactylus,
BYU 2024, a
synsacrum, belonged to an anurognathid.
Mesadactylus is from the Late Jurassic
Morrison Formation of the
USA. Indeterminate anurognathid remains have also been reported from the Middle Jurassic
Bakhar Svita of
Mongolia.
