Lamprotula bazini – Rare Extinct Unionidae from Hebei

Lamprotula bazini, an extinct species from Hebei Province, China, is known for its exceptionally thick and heavily built shell with pronounced surface convexity. All known specimens are subfossils recovered from sedimentary deposits, and individuals retaining intact periostracum are exceedingly rare. This species holds great value for researchers studying extinction events and the fossil record of freshwater mollusks.
