''Lanthaniscus'' is an extinct genus of lanthanosuchoid ankyramorph parareptile known from the Guadalupian epoch (Late Roadian to latest Wordian age) of Eastern Europe, Russia. ''Lanthaniscus'' was first named by M. F. Ivakhnenko in 1980 and the type species is ''Lanthaniscus efremovi''. ''L. efremovi'' was originally described on the basis of the holotype PIN 3706/9 from Peza-1 locality, Krasnoshchel' Formation, of Arkhangelsk.〔 Various authors had assigned it to the family Lanthanosuchidae,〔deBraga, M. and Rieppel, O. (1997). "Reptile phylogeny and the interrelationships of turtles." ''Zoological Journal of the Linnean Society'', 120: 281-354.〕 however Ivakhnenko who described an additional specimen of ''L. efremovi'' in 2008, assigned ''Lanthaniscus'' to its own family, the Lanthaniscidae. The additional specimen PIN 4543/2, was collected from the same formation as the holotype, from the Nisogora locality, which is slightly younger in age. ==References==
