The extinct Solenoporaceae have traditionally been interpreted as a group of

Corallinales.[4]

The genus from which they take their name, Solenopora, originates in the Ordovician.[5] Unlike the Corallinaceae, this family has large vegetative cells and an undifferentiated thallus.[5] Additionally there are external, non-calcified sporangia.[6]

The differences in structure suggest that the holotype is not an alga at all, but rather is a

chaetetid sponge. Post-Palaeozoic specimens therefore require re-classification.[7] However, some algal taxa are still classified within the genus.[8]

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.[8]

The solenoporaceae mineralized with calcite.[9]

Other genera within the Solenoporaceae

Although the following other genera have been included in this family, their status is uncertain due to the loose definition of the family.[3][7]
