Tabulate fossils are almost exclusively colonial. It's difficult to differentiate Scleractinian and Rugose fossils this way as both have colonial and solitary species. Scleractinian and Rugose corals both also have well developed septa, so this cannot be used to tell the difference. But again, tabulate corals have weak or absent septa.Favosites, extinct genus of corals found as fossils in marine rocks from the Ordovician to the Permian periods (between 488 million and 251 million years old).
