Askeptosauridae is a family of thalattosaurs within the superfamily Askeptosauroidea. Fossils have been found from Italy, Switzerland, and China. Askeptosaurids are distinguished from other thalattosaurs by their long necks and narrow skulls. ==Classification== Askeptosauridae was named in 1952 to include the genus ''Askeptosaurus''. In 2000, the genus ''Anshunsaurus'', which includes two species, was added to the family. In a 2005 phylogenetic analysis, ''Endennasaurus'' was included within Askeptosauridae. Later that year a new study placed ''Endennasaurus'' outside Askeptosauridae as a basal member of Askeptosauroidea.〔 More recent studies have placed the genus ''Miodentosaurus'' from China in the family as well. Below is a cladogram modified from Wu ''et al.'' (2009) showing the phylogenetic relationships of askeptosaurids: }} }}
