Hindsiclava pyrgoma is an extinct species of sea snail, a marine gastropod mollusc in the family Pseudomelatomidae, the turrids and allies.[1]
Description
Hindsiclava pyrgoma is a species of marine gastropod in the family Pseudomelatomidae. The shell of this extinct sea snail reaches a length of approximately 35.5 mm and a diameter of 10.5 mm, giving it a slender, elongate-fusiform shape typical of the genus.
The shell is composed of numerous whorls, each sculptured with prominent axial ribs and fine spiral striations that create a lattice-like appearance. The suture is distinct and slightly impressed. The aperture is elongated and narrow, terminating in a moderately long siphonal canal. The outer lip is sharp and may have had a slight sinus near the suture, characteristic of many turrids. The protoconch, if preserved, likely consisted of smooth, rounded whorls, indicating a planktotrophic larval stage.
Distribution
Fossils of this marine species have been found in Miocene strata in Panama; age range: 7.246 to 5.332 Ma
