Sunnyodon
Sunnyodon is a genus of tiny, extinct mammal, probably of the Lower Cretaceous. Found in what is now southern England and Denmark, it was a relatively early member of the extinct order of Multituberculata. It is part of the suborder Plagiaulacida and family Paulchoffatiidae.
The genus Sunnyodon was named by Zofia Kielan-Jaworowska and Ensom P.C. in 1992 based on a single specimen.
Fossil remains of the species Sunnyodon notleyi Lower Cretaceous-age strata of the Lulworth Formation in Durlston Bay, Dorset, England and the Rabekke Formation in Denmark. This is a tooth-based species.
A tooth from the Danish island of Bornholm was assigned to Sunnyodon in 2004. It is the first fossil of a Mesozoic mammal found in Scandinavia.
