Gemmocolus is an extinct genus of sea snails, marine gastropod molluscs in the family Fasciolariidae.[2] The genus includes two species, G. ectypa and G. gemmata, both known from the Miocene of New Zealand.
Description
[edit]The genus has a differing gemmate sculpture compared to other closely related genera such as Falsicolus.[3]
Taxonomy
[edit]Gemmocolus was first described by Phillip A. Maxwell in 1992 as a subgenus of Falsicolus.[1] By 2009, it was raised to genus level.[4]
Distribution
[edit]Fossils of the genus date to the early Miocene and middle Miocene of New Zealand.[5][1] Fossils found in the Westland District may represent a third, undescribed species.[1]
Species
[edit]Species within the genus Gemmocolus include:[2]
- † Gemmocolus ectypa (Marwick, 1931)
- † Gemmocolus gemmata (A. W. B. Powell, 1935)
