Further Informations
At their peak in the Paleozoic era, the brachiopods were among the most abundant filter-feeders and reef-builders in the sea, and occupied as well ecologigal niches. Brachiopod fossils have been useful indicators of climate changes during the Paleozoic.
Spirifer sp. attach to hard surfaces with its pedicle (“stalk”). It has a lophophore, a crown of tentacles whose cilia (fine hairs) create a water current that enables them to filter food particles out of the water.
