	Biostratigraphy; Bones; Cretaceous; Dimetrodons; Fossils; Geologic Time; Paleontology; Pelycosaurs; Permian; Skeletons; Vertebrata; Vertebrates	Dimetrodon skeleton on display. The Dimetrodon is not a dinosaur, but a pelycosaur. Thought to be a carnivore, this animal lived during the Permian period (280-245 million years ago). View Geological Time Scale for this image.

	Agate; Bones; Cenozoic; Fauna; Fossil Beds; Fossil Record; Fossils; Hills; Hills; Megafossils; Miocene; Mounds; Outcrops; Paleontologic Record; Paleontology; Rocks; Silicates; Tertiary	Agate Fossil Beds National Monument is located in the Niobrara River Valley in Nebraska. The park takes its name from thin lenses of agate (White River Silicate Group) in the area. Miocene-age rocks are exposed in the park in the bluffs above the Niobrara River wetlands and contain an excellent fossil record. Twenty million years ago animals such as the Dinohyus (giant pig-like animal), Stenomylus (small gazelle-camel), and Menoceras (short rhinoceros) roamed the plains. There were also carnivorous beardogs wandering around, and the land beaver Paleocastor dug spiral burrows that remain as today’s trace fossils (Daemonelix) into the ancient riverbanks. There are remnants of the ancient grasses and hoofprints of prehistoric animals in Miocene sediments preserved in the park, as well as layers of fossilized bones.

	Biostratigraphy; Fossils; Geologic Time; Hills; Landforms; Landscape; Paleontology; Sedimentary Rocks; Sediments; Terrigenous Materials	Hills of Dinosaur Provincial Park in Alberta, Canada. Dinosaur Provincial Park is considered to be among the richest fossil sites in the world. Because of the abundance and diversity of dinosaur remains, the rich environments for plants and animals, and the spectacular badlands, Dinosaur Provincial Park was declared a UNESCO World Heritage Site in 1979.

	Biostratigraphy; Bones; Dinosauria; Fossils; Geologic Time; Hadrosaurs; Ornithopoda; Paleontology; Skeletons; Vertebrata; Vertebrates	Foot cast of an Ornithopod. The Ornithopoda are a group of medium to large plant-eating dinosaurs. They include one of the earliest discovered dinosaurs Iguanodon, as well as the famous crested and "duck-billed" hadrosaurs. Several of these are noted for the spacious and bizarrely shaped sinus regions in their skulls. All ornithopods were herbivores and mostly bipedal.
