Laugiidae is an
They are notable for the extreme temporal disjunction seen between genera; two genera, Laugia and Belemnocerca, are known from the
latimerioid coelacanth lineage; almost all other non-latimerioid coelacanths were extinct by the Carnian stage of the Late Triassic, leaving only the latimerioids (Latimeriidae and Mawsoniidae) as the dominant coelacanth groups. It has been estimated that the laugiids diverged from the latimerioids & allied taxa (such as the Whiteiidae) during the Early Permian.[3]

A potential indeterminate genus is known from the Late Triassic of China.[4][5] The Carboniferous genus Synaptotylus was previously included in this family, but is no longer thought to be a member.[6]
Some studies indicate that the genus Piveteauia, known from the Early Triassic of Madagascar and previously considered a member of the Whiteiidae, may actually be a laugiid.[3]
