extinct mammal of the UpperJurassic . It was a relatively early member of the also extinct orderMultituberculata . It was a resident ofPortugal during the "age of thedinosaur s." It's in the suborder "Plagiaulacida " and familyPaulchoffatiidae .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, thegenus was rechristened a year later.References
