86 - Physa

Hello friends, Welcome to the  Fossil   Repository at the Department of Geology, Shivaji Science College, Nagpur.

I am Physa, belonging  to the Kingdom Animalia and the Phylum Mollusca. I possess a distinctive shell, typically conical or cylindrical in shape, spiralling in a counterclockwise direction. My shell is composed of calcium carbonate, offering protection and support to my soft body within. My body features a muscular foot, which I use for locomotion, and a head with sensory organs and a mouth for feeding.

I am primarily an aquatic creature, inhabiting freshwater bodies such as ponds, lakes, and slow-moving streams. I am known for my adaptability to various environmental conditions, thriving in both stagnant water and mildly polluted habitats. I can be found distributed across various regions of the world, particularly in North America, Europe, and Asia. My genus has a widespread distribution, indicating a long history of existence spanning millions of years. I  have been discovered in sedimentary rock formations dating back to the Cenozoic era, particularly the Miocene and Pliocene epochs. Some fossils even trace back to the late Paleogene period.
