''Plesiochoffatia'' is an extinct mammal of the Upper Jurassic. It was a relatively early member of the also extinct order Multituberculata. It was a resident of Portugal during the "age of the dinosaurs." It's in the suborder "Plagiaulacida" and family Paulchoffatiidae. The genus ''Plesiochoffatia'' ("near Choffatia") was named by Hahn G. and Hahn R. in 1999. It has also been known as ''Parachoffatia'' ("beside Choffatia") Hahn & Hahn, 1998 (preoccupied). Remains have been found in the Kimmeridgian (Upper Jurassic)-age strata of Guimarota, Portugal. Three species were described in the same study under the name of ''Parachoffatia''; (''P. peparethos'', ''P. staphylos'' and ''P. thoas''). As something else had already been given that name, the genus was rechristened a year later. ==References== * Hahn & Hahn (1999), Nomenklatorische Notiz: Namens-Änderung bei Multituberculata (Mammalia).
