Fordilla

Fordilla
F. troyensis; outer surface (top) and cast of internal anatomy[1]
Scientific classification
Kingdom: Animalia
Phylum: Mollusca?
Genus: Fordilla

The Early Cambrian fossils Fordilla and Pojetaia are regarded as bivalves.[2][3][4][5] Their inner shell layers were constituted of layers of carbonate akin to the laminar aragonite layer in extant monoplacophora.[6]
