Sunnyodon

Sunnyodon is a tiny, extinct mammal, probably of the Lower Cretaceous. It was a relatively early member of the also extinct order of Multituberculata. It lived in obscurity in southern Engand during 'the age of the dinosaurs'.
(For the more technically inclined, suborder "Plagiaulacida", family Paulchoffatiidae.)
