''Xenachoffatia'' is a small Jurassic mammal from Portugal. It was a relatively early member of the also extinct order of Multituberculata. It lived during "the age of the dinosaurs" and belongs to the suborder Plagiaulacida, family Paulchoffatiidae. The genus ''Xenachoffatia'' ("for Xena Choffat") was named by Hahn G. and Hahn R. in 1998. The primary species ''Xenachoffatia oinopion'' (Hahn & Hahn, 1998) was found in Kimmeridgian (Upper Jurassic) Camadas de Guimarota of Guimarota, Portugal. The classification is based on three upper molars. == References == * Hahn & Hahn (1998), "Neue Beobachtungen an Plagiaulacoidea (Multituberculata) des Ober-Juras. 3.
