The genus from which they take their name, Solenopora , originates in the Ordovician. Unlike the Corallinaceae , this family has large vegetative cells and an undifferentiated thallus. Additionally there are external, non-calcified sporangia. The differences in structure suggest that

9-435: The holotype is not an alga at all, but rather is a chaetetid sponge. Post-Palaeozoic specimens therefore require re-classification. However, some algal taxa are still classified within the genus. Some specimens of algal Solenopora retain an original pink colouration, which is banded with growth stages of the fossil; this is produced by boron-containing hydrocarbons. The solenoporaceae mineralized with calcite. Although
