What is nerinea trinodosa?

Nerinea trinodosa is an extinct species of marine mollusk that belonged to the class Gastropoda and the family Nerineidae. This species is characterized by its distinctively ribbed and elongated shell, which is often found in fossil records from the Mesozoic era. Fossils of Nerinea trinodosa provide valuable insights into the evolutionary history of gastropods and the marine environments of its time. Its presence in the fossil record helps paleontologists understand past biodiversity and geological conditions.
