The genus Sunnyodon (meaning "Sunny tooth", after Sunnydown Farm) was named by Zofia Kielan-Jaworowska and Ensom P.C. in 1992 based on a single specimen.
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.[1] A tooth has also been assigned to Sunnyodon from the Berriasian aged Angeac-Charente bonebed in France.[2]
