protomausolea
Protomausolea is a genus of fossilized marine invertebrates belonging to the class Gastropoda, commonly known as snails. These organisms are known from the Paleozoic era, predominantly appearing in the late Cambrian to early Ordovician periods, approximately 500 to 450 million years ago. Protomausolea species are characterized by their coiled shells, which exhibit a high degree of morphological variability. The shells are typically small, ranging from a few millimeters to a few centimeters in size, and often display distinctive ornamentation, such as ribbing or spines.
Fossils of Protomausolea have been discovered in stratigraphic layers across various regions, including North America, Europe,
Protomausolea is often classified within the broader group of early gastropods, and its evolutionary relationships remain
