Calliostoma bullatum is a species of sea snail, a marine gastropod mollusk in the family Calliostomatidae. [1]
Fossil evidence indicates that this species formerly lived as far north as what is now the Mediterranean Sea, but presently it is only known from abyssal habitats off the coast of West Africa, where it largely lives among deep-water coral reefs. [2]
This species is notable for being described as a fossil well before live individuals were found. The species was originally described from fossil specimens from early-mid Pleistocene outcrops in southern Italy. After over a century, live individuals were found in deepwater reefs off the coast of Mauritania. This makes C. bullatum an example of a fossil Lazarus taxon. [2]
Anthozoa is a class of marine invertebrates which includes the sea anemones, stony corals and soft corals. Adult anthozoans are almost all attached to the seabed, while their larvae can disperse as part of the plankton. The basic unit of the adult is the polyp; this consists of a cylindrical column topped by a disc with a central mouth surrounded by tentacles. Sea anemones are mostly solitary, but the majority of corals are colonial, being formed by the budding of new polyps from an original, founding individual. Colonies are strengthened by calcium carbonate and other materials and take various massive, plate-like, bushy or leafy forms.
In paleontology, a Lazarus taxon is a taxon that disappears for one or more periods from the fossil record, only to appear again later. Likewise in conservation biology and ecology, it can refer to species or populations that were thought to be extinct, and are rediscovered. The term Lazarus taxon was coined by Karl W. Flessa & David Jablonski in 1983 and was then expanded by Jablonski in 1986. Wignall and Benton defined Lazarus taxon as, ‘At times of biotic crisis many taxa go extinct, but others only temporarily disappeared from the fossil record, often for intervals measured in millions of years, before reappearing unchanged’. Earlier work also supports the concept though without using the name Lazarus taxon, like work by Christopher R. C. Paul.
