'''Microdomatidae''' is an extinct [family](/source/Family_(taxonomy)) of [fossil](/source/fossil) [sea snail](/source/sea_snail)s, [marine](/source/marine_(ocean)) [gastropod](/source/gastropod) [mollusk](/source/mollusk)s in the superfamily [Trochoidea](/source/Trochoidea_(superfamily)).<ref name=":0">Taxonomy of the Gastropoda (Bouchet & Rocroi, 2005)</ref> They were extant throughout [Southeast Asia](/source/Southeast_Asia), [Northern Europe](/source/Northern_Europe), [Venezuela](/source/Venezuela), the [United States](/source/United_States), and [Northern Mexico](/source/Northern_Mexico). Their fossil records span from the Early Devonian to the Early Triassic, approximately 411 to 251 million years ago.<ref>{{Cite web |date=14 October 2025 |title=Microdomatidae |url=https://mindat.org/taxon-3245541.html }}</ref>

== Appearance ==
The umbilicus of Microdomatidae snails was typically well-developed and often quite wide, forming a noticeable central depression or hollow on the underside of the shell. This feature helps distinguish them from some other fossil sea snails, where the umbilicus may be narrow or even absent.<ref>{{Cite web |last=Galli |first=Claudio |date=15 October 2025 |title=WMSDB {{!}} Conchology |url=https://conchology.be/index.php?t=2204&CODsp=6412000003&Genus=Microdoma&species=carinata&variety=&srsltid=AfmBOopf8b131UolU-g6nP0k0_r19e-QXudBl7fLNwxyBa45I_2phzhn |access-date=15 October 2025 |website=Conchology}}</ref>
