Horn Coral had plenty of tentacles sticking out to gather their food and plankton from the seawater. The tentacles made a flower like appearance.
During the Paleozoic Era, there were so many horn corals that they helped to create reefs on the ocean floor.
The oldest of the Rugosa corals are found in rocks from the Ordovician Period. Many species evolved during the Paleozoic Era. As a group they flourished until the Permian Period when they became extinct along with most living things during the Great Permian Extinction.
