Iseolutus

Iseolutus is a genus of extinct ammonites, a diverse group of marine mollusks that lived from the Devonian to the end of the Cretaceous period. Ammonites are characterized by their coiled shells, which often exhibit intricate patterns and sutures. The genus Iseolutus is known for its specific shell morphology and geological distribution.

Fossils of Iseolutus have been found in various locations worldwide, indicating its presence across ancient oceans. The precise taxonomic classification of Iseolutus places it within the order Phyllocerida, a group known for its smooth, evolute shells. The sutures, which are the lines where the shell chambers meet the outer wall, are typically simple and rounded in Iseolutus, distinguishing it from other ammonite genera.

The paleoenvironment in which Iseolutus lived is thought to have been marine, likely in relatively shallow to moderately deep waters. Like other ammonites, Iseolutus was a free-swimming organism that inhabited the oceans of the Mesozoic Era. Its extinction, along with all other ammonites, occurred at the end of the Cretaceous period, coinciding with the K-Pg extinction event. The study of Iseolutus contributes to our understanding of ammonite evolution, diversity, and the ancient marine ecosystems they inhabited.
