Details

High Quality Content by WIKIPEDIA articles! For a long time it was thought that Volborthella, some fossils of which pre-date 530 million years ago, was a cephalopod. However discoveries of more detailed fossils showed that Volborthella's small, conical shell was not secreted but built from grains of the mineral silicon dioxide (silica), and that it was not divided into a series of compartments by septa as those of fossil shelled cephalopods and the living Nautilus are. This illusion was a result of the laminated texture of the organisms' tests.
