Tanystropheidae is an extinct
Tanystropheids are known from Europe, Asia (Russia, China, and Saudi Arabia), North America[5] and probably South America (Brazil).[6] The presence of tanystropheids in Europe and China indicate that they lived along much of the coastline of the Tethys Ocean.[7] However, species in western North America are found in terrestrial deposits, suggesting that as a group, tanystropheids were ecologically diverse.[5]
Relationships among tanystropheid species have been difficult to resolve because most specimens were flattened during fossilization and are preserved two-dimensionally. Three-dimensional fossils are known from Europe and North America.[5]

A later 2024 study grouped Tanystropheidae along with Trachelosauridae in the new clade Tanysauria.[9]
