Drimylennella

Drimylennella is a fictional genus of extinct marine gastropods created for illustrative purposes. In this constructed taxonomy, it belongs to the family Drimylidae and is known from late Cretaceous to early Paleogene deposits in the western North Atlantic. The available material comprises small, single-shell fossils representing a brief lineage within Neogastropoda.

Two described species are assigned to Drimylennella: the type species Drimylennella cerasiformis and Drimylennella radiata. The genus was established to demonstrate certain shell features and to illustrate how paleontologists distinguish taxa by sculpture, aperture, and protoconch details.

Shells are up to 6 mm in height, elongate-conical with 7 to 8 whorls. The sculpture combines fine axial ribs with spiral cords, creating a reticulate pattern. The aperture is ovate, the outer lip crenulated, and the siphonal canal short. The apex is slightly acute, and the peristome forms a continuous, smooth margin in mature individuals.

Fossils were described in a synthetic scenario by the fictional paleontologist S. Lente in 1993. The name Drimylennella is constructed from a fictional donor name Drimy Lenn and the common gastropod suffix -ella.

In this fictional scenario, fossils are known from shallow-marine deposits corresponding to depths of 20–40 meters. The genus is interpreted as a micro-grazer feeding on biofilm and detrital material on hard substrates.

This article describes a fictional genus created for demonstration and should not be treated as a record of a real taxon.
