Solenopora
Template:Short description Template:Automatic taxobox
The extinct Solenoporaceae have traditionally been interpreted as a group of red algae ancestral to the Corallinales.[1]
The genus from which they take their name, Solenopora, originates in the Ordovician.[2] Unlike the Corallinaceae, this family has large vegetative cells and an undifferentiated thallus.[2] Additionally there are external, non-calcified sporangia.[3]
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.[4] However, some algal taxa are still classified within the genus.[5]
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.[5]
The solenoporaceae mineralized with calcite.[6]
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.[7][4]
- Dendronella Moussavian and Senowbari-Daryan 1988
- Elianella
- Marinella Pfender 1939
- Metasolenopora Pia 1930
- Parachaetetes Deninger 1906
- Pycnoporidium Yabe and Toyama 1928
- Solenoporella Rothpletz
- Tauristorea Senowbari-Daryan and Link 2005
