description Bandringa Overview

Bandringa is an extinct genus of shark that lived approximately 300 million years ago during the Carboniferous period, first described in 1969 from specimens found in the Mazon Creek fossil beds of Illinois. Notable for its distinctive elongated snout, which accounted for roughly one-third of its total body length, Bandringa is considered one of the earliest known sharks to display sexual dimorphism. The abundance of juvenile specimens in particular fossil deposits indicates that these ancient sharks utilized specific marine environments as nursery areas, a reproductive strategy still observed in modern sharks.

Bandringa had a long, narrow snout that made up roughly half of its body length. Its unusual head shape is one of the main features used to recognize the genus.

Did Bandringa live in the ocean?
