The study of past ecologies by using the evidence of fossils

One of a peculiar kind of internal buds, or germs, produced in the interior of certain Bryozoa and sponges. They are protected by a firm covering, and are usually destined to perpetuate the species during the winter season. They burst open and develop in the spring. In some freshwater sponges they serve to preserve the species during the dry season.
