Ivan Antonovich (real patronymic Antipovich) Yefremov (Ива́н Анто́нович (Анти́пович) Ефре́мов; 22 April 1908 – 5 October, 1972), last name sometimes spelled Efremov, was a Soviet paleontologist, science fiction author and social thinker. He originated taphonomy, the study of fossilization patterns.

Ancestry
Yefremov's father, Antip Kharitonovich, was born in 1861 in Makaryevskiy Uyezd of Nizhny Novgorod Governorate into a family of Old Believers. In 1882, he was conscripted and sent to serve in the Semyonovsky Regiment in Saint Petersburg, where he was eventually promoted to a non-commissioned officer. After 16 years of service, he retired and was granted the position of a collegiate registrar, the lowest class in the Russian Table of Ranks. Soon thereafter, Antip Kharitonovich moved to Vyritsa, where he built a house and rented a saw mill on the Oredezh River from the local landowner. With the construction boom in Saint Petersburg and the opening of a railway line to Vyritsa, this quickly proved to be a very profitable enterprise, which facilitated Antip Kharitonovich's acceptance into the Merchant Guild.
