=== Evolution ===
Despite only having fossils as early as the [[Cretaceous]], Scolecophidia itself likely originated in the [[Middle Jurassic]], with [[Anomalepididae]], [[Leptotyphlopidae]], and [[
Scolecophidians are believed to have originated on [[Gondwana]], with anomalepidids and leptotyphlopids evolving in west Gondwana (South America and Africa) and typhlopids, gerrhopilids, and xenotyphlopids on east Gondwana, initially on the combined India/Madagascar land mass, during the [[Mesozoic]].<ref name="Vidal-2010"/> Typhlopids then dispersed to Africa and Eurasia. South American typhlopids appear to have evolved from African typhlopids that [[oceanic dispersal|rafted]] across the Atlantic about 60 million years ago; they, in turn, dispersed to the Caribbean about 33 million years ago.<ref name="Vidal-2010"/> Similarly, typhlopids appear to have reached Australia from Southeast Asia or Indonesia about 28 million years ago.<ref name="Vidal-2010"/>
