Coral Specimen - possibly Astrangia sp.?
SITE LOCATION: Yorktown formation Beaufort County, Aurora, North Carolina
TIME PERIOD: Pliocene age (5.333 million to 2.58 million years ago)
Data: Unknown genus, possibly Astrangia sp. Corals are marine invertebrates in the class Anthozoa of phylum Cnidaria. They typically live in compact colonies of many identical individual polyps. The group includes the important reef builders that inhabit tropical oceans and secrete calcium carbonate to form a hard skeleton. A coral "group" is a colony of myriad genetically identical polyps. Each polyp is a sac-like animal typically only a few millimeters in diameter and a few centimeters in length. A set of tentacles surround a central mouth opening. An exoskeleton is excreted near the base. Over many generations, the colony thus creates a large skeleton that is characteristic of the species. Individual heads grow by asexual reproduction of polyps. Corals also breed sexually by spawning: polyps of the same species release gametes simultaneously over a period of one to several nights around a full moon.
Kingdom: Animalia
Phylum: Cnidaria
Class: Anthozoa
