Choiaella is an extinct genus of sea sponge ranging from the Chengjiang lagerstatten until the Lower Silurian.[1]
It is closely related to the genera Choia and Allantospongia, which the Chengjiang fauna species C. radiata coexisted sympatrically with.
The species C. scotica is known from the Caradoc-aged fine sandstone of Wallace's Cast, Southern Uplands of Scotland.[1]
The Silurian species has not been formally named.[1]
