Also called Rugose Corals, Horn Corals were plentiful in the ancient oceans. At first glance, it is easy to mistake a horn coral for a horn or even a tooth, but that was simply how they were shaped.

Solitary Horn Corals ranged in size; the small, common varieties were about 1-4 inches long, while larger species could reach up to 3 feet long.
