The extinctSolenoporaceaehave traditionally been interpreted as a group ofred algaeancestral to theCorallinales.^[4]

The genus from which they take their name,Solenopora,originates in the Ordovician.^[5]Unlike theCorallinaceae,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 achaetetidsponge. Post-Palaeozoic specimens therefore require re-classification.^[7]However, some algal taxa are still classified within the genus.^[8]

Some specimens of algalSolenoporaretain 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]
