Temporal range: Early Cretaceous, Hauterivian–Barremian
|Restoration of a Wakinosaurus|
Wakinosaurus (meaning "Wakino lizard") is a genus of theropod dinosaur from the Early Cretaceous (Hauterivian-Barremian) Sengoku Formation of Kyushu, Japan. The genus is a tooth taxon, based solely on a tooth.
In 1990 Masahiro Sato in Fukuoka found the tooth of a theropod. The same year Yoshihiko Okazaki first reported on the find. In 1992 Okazaki named the type species, Wakinosaurus satoi. The generic name refers to the Wakino Subgroup of the Kwanmon Group, of which the Sengoku Formation is a member. The specific name honours Sato.
The holotype is KMNH VP 000,016, a single damaged tooth, the crown of which must have been about seven centimetres long. Its base length is 32.9 millimetres (1.30 in), its base width 10.4 millimetres (0.41 in). It has about thirty serrations per five millimetres.
