Trigoniidae is a taxonomic family of saltwater clams, marine bivalve mollusks in the superfamily Trigonioidea. There is only one living genus, Neotrigonia, but in the geological past this family was well represented, widespread and common. The shells of species in this family are morphologically unusual, with very elaborate hinge teeth, and the exterior of the shell is highly ornamented.
==Description== The most striking feature of the Trigoniidae, which has attracted attention for centuries, is their external ornamentation. This is usually present as ribs or costae, or rows of aligned tubercles. The hinge teeth of the shell are unusually elaborate in structure. The living animal has no siphon.
