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