Penion proavitus is an extinct species of marine snail or whelk, belonging to the true whelk family Austrosiphonidae.[1][2][3][4][5]
Description
Penion proavitus fossils are the earliest known specimens of Penion siphon whelks.[3][4] The species was medium-to-large in size.[2][5]
It is possible that fossils of Penion proavitus represent a stem lineage that was the common ancestor of Penion, Kelletia and Antarctoneptunea, instead of a species of Penion itself.[4]
Distribution
Fossils of Penion proavitus are found in New Zealand's South Island.[2] The species lived in the seas surrounding Zealandia between 56 and 66 million million years ago (Teurian stage).[3]
