Persististrombus nodosus is an extinct species of fossil sea snail, a marine gastropod mollusk in the family Strombidae, the conchs. [2] [3]
Persististrombus nodosus is quite polymorphic, but it is usually slender with high spire. Spire whorls show strong nodes or spines. The sutural ramp and the last whorl bear spiral ribs, quite variable in number and strength. The surface of the last whorl is crumpled., with a slightly concave area. [4]
Fossils of Persististrombus nodosus are found in marine strata of the Miocene (age range: from 20.43 to 7.246 million years ago.). Fossils are known from Austria, France, Greece, Italy, Poland and Turkey. [5]
Strombidae, commonly known as the true conchs, is a taxonomic family of medium-sized to very large sea snails in the superfamily Stromboidea, and the Epifamily Neostromboidae. The term true conchs, being a common name, does not have an exact meaning. It may refer generally to any of the Strombidae but sometimes is used more specifically to include only Strombus and Lambis. The family currently includes 26 extant, and 10 extinct genera.
The gastropod shell is part of the body of a gastropod or snail, a kind of mollusc. The shell is an exoskeleton, which protects from predators, mechanical damage, and dehydration, but also serves for muscle attachment and calcium storage. Some gastropods appear shell-less (slugs) but may have a remnant within the mantle, or the shell is reduced such that the body cannot be retracted within (semi-slug). Some snails also possess an operculum that seals the opening of the shell, known as the aperture, which provides further protection. The study of mollusc shells is known as conchology. The biological study of gastropods, and other molluscs in general, is malacology. Shell morphology terms vary by species group.
