== Etymology == The Latin genus name ''Striatolamia'' refers to the striations on the surface of the teeth.
== Taxonomy == This genus had been assigned to families Mitsukurinidae and Striatolamiidae by other authors.<ref name=bb>Jim Bourdon [http://www.elasmo.com/frameMe.html?file=genera/cenozoic/sharks/striatolamia_new.html&menu=bin/menu_genera-alt.html Striatolamia - The Life and Times of Long Dead Sharks]</ref>

== Description == ''Striatolamia'' species could reach a length of about {{convert|350|cm}}. Its teeth are notably big and rather common in sediments. The anterior teeth have elongated crowns, with striations on the lingual face and small lateral cusplets. The lateral teeth are smaller and broader, with weaker striations.<ref>[http://www.squali.com/squali_fossili/striatolamia.html Squali]</ref>
''S. macrota'' anterior teeth have smaller roots than ''S. striata'', and they are often recurved. Another difference between these two species is the length of their teeth. Teeth of ''striata'' are generally smaller ({{convert|13|to|51|mm}}) than ''macrota'' ({{convert|19|to|38|mm}}).<ref name=bb/>
== Distribution and habitat == Most widespread species of ''Striatolamia'' are ''S. striata'' and ''S. macrota''. Fossil teeth and calcified vertebrae of ''Striatolamia'' species have been found all over the world.<ref name=aa/> These sharks lived in waters with low salinity.
