Phylum: Brachiopoda
Class: Rhynchonellata
Order: Speriferida
Familiy: Spiriferidae
Genus: Spirifer sp.
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.
The models are made by using casted fossil original finds, found in Gerolstein (D), middle devonian side. We offer two models.
No.1: Spirifer sp. with open shells. Visible are the lophophor and the tentacles used by the animal to filter the water for food particles.
No.2: Spirifer sp. with closed shells
No.1: Spirifer sp. with open shells. Visible are the lophophor and the tentacles used by the animal to filter the water for food particles.
