Gigatitan is an extinct genus of titanopteran insect that lived in Kyrgyzstan during the Triassic period. The type species is G. vulgaris, described by Aleksandr Grigorevich Sharov in 1968.[1] Fossils of Gigatitan have been found in the Madygen Formation.[2] In life, Gigatitan was a mantis-like predator with a wingspan of approximately 33 centimetres (13 in). Its forelimbs were similarly enlarged and bore spines for prey capture.[3] The ovipositor of Gigatitan bore sharp cutting ridges. These were likely used to excise holes in plant matter for oviposition, similar to some modern Orthoptera.[4] It is the type genus of the family Gigatitanidae, in which the closely related Nanotitan and Ootitan are also included.[1][5]
