M. robustus |
Meketibolodon is a genus of extinct mammal from the Kimmeridgian (Upper Jurassic) of Portugal. It was a relatively early member of the also extinct order Multituberculata, suborder Plagiaulacida, family Paulchoffatiidae. It lived in Portugal during the Mesozoic era, also known as the "age of the dinosaurs." The genus was named by Hahn G. in 1993 based on nine specimens of lower jaw.
"Meketibolodon (Hahn 1993) is distinguished from the other genera [of Paulchoffatiidae] by two characters: the tooth row is significantly convexly curved upwards, and the corpus mandibulae has angled margins ventrally (Hahn and Hahn 1998b). The incisor is more strongly curved than it is the case in Paulchoffatia, and its root is longer. The corpus mandibulae is similarly massive to that in Paulchoffatia" (Hahn and Hahn 2000, p.105). The corpus mandibulae is the part of the lower jaw beneath the tooth row, and meketi is Greek for 'no longer'.
The primary species Meketibolodon robustus, is based on remains found in Guimarota, Portugal.
