Class: Bivalvia
Order: Ostreoida
Family: Posidoniidae
Genus: Daonella

In paleontology, Daonella was a genus of bivalves (clams) of the middle to late Triassic period.[1] They are related to the genera Aparimella and Halobia.[2] Since they were ubiquitous in the Arctic, Tethys and Panthalassa seas, they are frequently used as index fossils in dating rocks to the Triassic period.[3] However, the systematic classification of the Daonella is still an area of ongoing research.[4]
