Summary
[edit]DescriptionSolenastrea hyades (fossil coral) (Croatan Formation, Lower Pleistocene; Beaufort County, North Carolina, USA) 1.jpg |
English: Solenastrea hyades (Dana, 1846) - fossil coral with encrusters from the Pleistocene of North Carolina, USA.
Scleractinians are significant reef-building organisms in Earth's warm, shallow oceans. They first appear in the Triassic and are the only group of stony corals in modern oceans (in the Paleozoic, tabulates and rugosans were the principal stony coral groups). Scleractinian corals consist of individuals or colonies of gelatinous polyps that secrete hard calcareous (CaCO3) skeletons. Most live in warm, tropical to subtropical, photic zone environments (the shallow portions of the world’s oceans where sunlight penetrates). Scleractinian corals are predators - they have stinging cells (nematocysts) in their tentacles that paralyze prey. They also obtain sustenance from microbes called zooxanthellae (usually dinoflagellates) that live in their tissues and need to be in sunlight to manufacture food by photosynthesis. The food is shared with the host coral. The dark structures at right are encrusting barnacles. The gray material at upper left is an encrusting cheilostome bryozoan colony. Classification: Animalia, Cnidaria, Anthozoa, Hexacorallia, Scleractinia, Faviina, Faviidae Stratigraphy: Croatan Formation (a.k.a. James City Formation), Lower Pleistocene Locality: unrecorded site in Beaufort County, eastern North Carolina, USA (probably the Lee Creek Mine near the town of Aurora) |
