Microdomatidae is an extinct family of fossil sea snails, marine gastropod mollusks in the superfamily Trochoidea. [1] They were extant throughout Southeast Asia, Northern Europe, Venezuela, the United States, and Northern Mexico. Their fossil records span from the Early Devonian to the Early Triassic, approximately 411 to 251 million years ago. [2]
