Mangelia chariessa

Mangelia chariessa is an extinct species of sea snail, a marine gastropod mollusk in the family Mangeliidae.

Description
Mangelia chariessa had a small, elongated shell with a length reaching up to 5.8 mm and a diameter of 2.5 mm. The shell was characterized by its intricate patterns and fine sculpturing, typical of the Mangeliidae family.

Distribution
This extinct marine species was found in the Alum Bluff Group, a geological formation in Florida, USA, which dates back to the Miocene epoch. The Alum Bluff Group is known for its rich fossil deposits, providing valuable insights into the marine life of that era.

Paleontological Significance
The discovery of Mangelia chariessa in the Alum Bluff Group contributes to the understanding of the diversity and distribution of marine gastropods during the Miocene. It helps paleontologists trace the evolutionary history of the Mangeliidae family and the environmental conditions of the time.
