Description
Description after Gibbes (1849) [941]:
Galeocerdo contortus, Gibbes. Figs. 71, 72, 73, 74.-This is an undescribed species, which is very abundant in the Eocene of South Carolina and Miocene of Virginia. The cone is longer and more acute with a twist outwardly in its upper third, which is characteristic. The inner face is rounded, while the outer is undulated; the edges are regularly indented, and on the anterior next the root the dentelures are more developed. The root is very thick and deep.
