About Kielanodon

Kielanodon is an extinct mammal of the Portuguese Upper Jurassic. It was a relatively early member of the also extinct order of Multituberculata. It eked out a living during the Mesozoic era, also known as the "Age of the Dinosaurs." It is in the suborder Plagiaulacida, family Paulchoffatiidae.

The genus Kielanodon, meaning "Kielan’s tooth" after Zofia Kielan-Jaworowska, was named by Hahn G. in 1987. The main species, Kielanodon hopsoni, also named by Hahn, is known from fossils found in the Kimmeridgian (Upper Jurassic)-age strata of Guimarota, Portugal. The identification is based on three upper jaws.
