Penion crawfordi is an extinct species of marine snail or whelk, belonging to the true whelk family Austrosiphonidae.[2] [3][1][2]

Description

Penion crawfordi is a large, extinct species of Penion siphon whelk.[1] Shells of P. crawfordi have spine-like, dorso-ventrally compressed nodules on the shell spire.[1]

(Original description) The shell is ovato-fusiform in shape and is distantly marked by spirally striated patterns. It consists of five whorls, where those of the spire appear distinctly flattened. Each of these spire whorls bears a row of tubercles located near the anterior suture, though this feature is largely covered up by the subsequent ventral whorl.

The body whorl is notably inflated and keeled, featuring a prominent row of nine large tubercles situated directly on the keel. Positioned just in front of them is a similar row of smaller tubercles. The aperture is oval in form, leading into what appears to be a short siphonal canal. [4]

Distribution

Fossils of Penion crawfordi are found in northern South Island and southern North Island in New Zealand.[1][5]
