Latouchella costata is an extinct species of marine invertebrate animal, that is considered to be a mollusk and which may be a sea snail, a gastropod.

Etymology

It was named by Edgar Sterling Cobbold in 1921 for the Rev. William Martin Digues La Touche of Wistanstow, Shropshire, England, in whose collection it was found.

Physical Appearance

Latouchella has a tightly coiled, spiral shell containing a number of low "walls" running up the front surface of the interior; these would have directed water currents within its shell. Between these walls are a series of furrows, parallel to the shell's aperture, giving casts of the internal structure the appearance of a railway line, with sleepers (created by furrows) tying together paired rails that run towards the apex of the shell.

Abilities

Helcionelloid species, like contemporary snails, require shells to shield their fragile bodies from dryness, mechanical harm, and predators. Muscle attachment and calcium storage are further functions of shells.

Ecology

Helcionelloids are ancient Cambrian gastropods that are crucial to the ocean ecology, if you assume that they are similar to sea snails but have less information. They inhabit a wide range of environments, including deep-sea areas and salt marshes.

Behavior

Like modern snails, helcionelloids are thought to be old and are generally not seen as pleasant due to their simple nature and lack of complicated emotions. Rather, their primary priority is survival.

Distribution and Habitat

It is a helcionellid from the Early Cambrian to Early Ordovician ages of the Tommotian epoch in what is now Siberia.
