Vericeras is an extinct genus of nautiloid cephalopod that lived in what would be Europe during the Silurian from 421—418.7 mya, existing for approximately 2.3 million years.[1]
Taxonomy[edit]
The type species, V. ambigena, was originally described by Joachim Barrande as "Orthoceras ambigena. Vericeras was assigned to Orthocerida by Sepkoski (2002).[2]
Morphology[edit]
The shell is an elongated orthocone with fine, longitudinal ribbing, very similar to the shells of its sister genus, Arionoceras.
Fossil distribution[edit]
Fossil distribution is exclusive to Silurian marine strata in Sardinia.
