Invertebrates - The Burgess Shale locality in British Columbia is probably the most famous invertebrate fossil site in the world. Trilobites, extinct three-lobed arthropods, are found in many localities around the world, such as Europe, Australia, China, Canada, and Utah. Some of the best preserved examples come from Morocco, Russia, and Oklahoma. Ammonites, related to the modern-day Nautilus, are famous from Europe and Madagascar, and are also found in Russia, South America, and even the United States. Insects in amber are commonly found along the Baltic Coastline and the Dominican Republic. Crinoids are unusual animals related to starfish and sea urchins. One of the most prolific areas for these fossil "sea lillies" is Crawfordsville, Indiana, although crinoids have been discovered in China and Australia.
Vertebrates - Dinosaurs are the world's most popular fossil vertebrates, and their fossils are most commonly found in the Western United States and Canada. Dino remains are also known from Europe, Africa, Argentina, and China. Aquatic reptiles, such as Mosasaurs and Plesiosaurs have been found in England, Morocco, Kansas, and Texas. Mammals, both large and small, are commonly exposed in the Badlands area of South Dakota and Nebraska. Alaska and Siberia are famous for beautifully preserved Mammoth fossils, ranging from teeth and tusks to complete animals. Fossil fish are relatively common in the fossil record. The Green River Formation of Southern Wyoming is world famous for both its variety of species and its sheer number of specimens. Complete fossil fish are also known from Europe, Lebanon, Brazil, and China. Shark fossils, especially teeth, are found all around the world. Some of the more well known fossil shark localities are the Eastern Seaboard of the United States, Chile, and Morocco.
