Rugose Horn Coral Morocco Devonian age (~400 million years ago) The Rugosa, also called the Tetracorallia, are an extinct order of solitary and colonial corals that were abundant in Middle Ordovician to Late Permian seas. Solitary rugosans (e.g., Caninia, Lophophyllidium, Neozaphrentis, Streptelasma) are often referred to as horn corals because of a unique horn-shaped chamber with a wrinkled, or rugose, wall. Some solitary rugosans reached nearly a meter in length. However, some species of rugose corals could form large colonies (e.g., Lithostrotion). When radiating septa were present -

Fossil Hexagonaria Coral Morocco (Probably west Sahara) Devonian age (359-419 Million years ago) Hexagonaria is a genus of colonial rugose coral. Fossils are found in rock formations dating to the Devonian period, about 350 million years ago. Specimens of Hexagonaria can be found in most of the rock formations of the Traverse Group in Michigan. Fossils of this genus form Petoskey stones, the state stone of Michigan. Kingdom: Animalia Phylum: Cnidaria Class: Anthozoa Order: Stauriida Family: Disphyllidae Subfamily: Hexagonariinae Genus: †Hexagonaria -

Kettneraspis sp. Trilobite Cravat Member-Bois d'Arc Formation, Coal County, Oklahoma Devonian Age (419.2- 358.9 million years ago) The Kettneraspis sp. trilobite was a bizarre creature of the ancient seas. The broad and long array of spines was likely a display protection against potential predators. The free cheeks of these extinct creatures had a unique fringe of small spines projecting outward, as well and one cannot wonder if they served to help stir up the ocean floor to aid in search of food as the creature crawled across the sea bottom. The eye stalks protruded up of -

Paraconularia ulrichana fossil Belen Formation, Calamarca, Bolivia Devonian Age (~390 million years) Conulariids had elongated, pyramidal exoskeletons, made up of rows of calcium phosphate rods. Most were square or rectangular in cross section, with prominent grooves at the corners. They lived attached to hard objects by a flexible stalk, and often lived in groups. Presumably they were filter feeders; how they reproduced is not known. They aren't that uncommon; there are a number of genera, and they ranged from the Middle Ordovician to the Triassic. There are even a few cases in which -
