Trilobites -One of the oldest animal life forms on earth, flourished in the ancient primordial seas from the Cambrian Period beginning 570 million years ago to the Permian Period which ended approximately 230 million years ago. A possible descendant of these diverse arthropods is the Horseshoe Crab as well as the insect commonly known as "pill bug" which often defensively roll up their external skeleton - a trait shared by all trilobites. |

Ammonites and Agoniatites - Ammonoidae -These varied and decorative invertebrate specimens evolved from nautiloids in the early Devonian Period around 450 million years ago. They flourished worldwide for approximately the next 370 million years and became extinct along with the dinosaurs in the late Cretaceous Period. Their descendant, the chambered nautilus, can still be found in the warm shallow seas of the Indian Ocean. |

Mosasaur Vertebrae Plates -The mosasaurs were a highly successful group of fish-eating reptiles that diversified and grew to 50 feet in length in the Late Cretaceous seas, at a time when the ichthyosaurs had died out and the plesiosaurs were in decline. "Mosasaurus" had a long slender body with a deep flat-sided tail which was used to power its swimming. The hands and feet were modified to paddles, probably used in steering and the long powerful jaws were lined with broad sharp teeth. These were used for piercing the shells of ammonites, a plentiful food source in the warm shallow seas of the Devonian through the Cretaceous periods. |

Sponge Spicules -These sponge spicules are siliceous or calcareous mineralized single crystals produced by large Ordovician sponges that lived in the warm shallow Saharan sea. The spicules were embedded in the walls of the fleshy part of the sponge to make it less appetizing to predators. |

Crinoids These specimens are popularly known as "Sea Lilies" or "Feather Stars". |
