Fossil Record of Gastropoda - Digital Atlas of Ancient Life
Gastropods have left behind an extraordinary fossil record that documents a rich evolutionary history. They are distinctive among animals for their high taxonomic, ecological, and environmental diversity.
The fossil record of freshwater Gastropoda – a global review
Here, I review the fossil record of freshwater gastropods on a global scale, ranging from their origins in the late Palaeozoic to the Pleistocene. As compiled here, the global fossil record of freshwater Gastropoda includes 5182 species in 490 genera, 44 families, and 12 superfamilies over a total of ~340 million years.
Gastropoda - Wikipedia
In rocks of the Mesozoic era, gastropods are slightly more common as fossils; their shells are often well preserved. Their fossils occur in ancient beds deposited in both freshwater and marine environments.
The Gastropoda - University of California Museum of Paleontology
There are about about 13,000 named genera for both Recent and fossil gastropods. They have a long and rich fossil record from the Early Cambrian that shows periodic extinctions of subclades, followed by diversification of new groups.
Class Gastropoda - Digital Atlas of Ancient Life
2021年9月16日 · Gastropods are the second largest class of animals (after the Insecta)—with 40,000–90,000 living species and at least 13,000 extant and fossil genera (Ponder and Lindberg, 2020)—and are also one of the most evolutionarily successful groups in the variety of ecosystems and habitats that they occupy.

Gastropods - British Geological Survey
Gastropods evolved early in the Cambrian, but since the Palaeogene they have become the most common molluscs, inhabiting both aquatic and terrestrial environments. We focus here on shelled forms that are normally found as fossils: Prosobranchia; Pulmonata; Opisthobranchia (although these are rather rare)
