			Below is a sampling of dinosaurs and other reptiles of the Permian, Triassic, and Jurassic Periods as presented at "The Dinosaur Place", a park in Montville, Connecticut, USA devoted to life-sized interpretations of dinosaurs. Since the reconstructions are based on fossil evidence, much interpretation is required before a life-like figure is constructed. The fossil evidence usually includes bones and teeth. Skin, internal organs, and outer appearance are usually missing. Existing reptiles are often used as a guide. The Dinosaur Place has used some interesting color schemes for some of their interpretations.
			Interpretation of Brachiosaurus, a huge herbivorous reptile of the Middle to Late Jurassic Period. It is estimated that these dinosaurs stood 40-50 feet tall, had a length of about 85 feet, and weighed 33-88 tons. Exhibit at "The Dinosaur Place", Montville, Connecticut, USA.

			Interpretation of Dimetrodon, a carniverous reptile of the Permian Period. It is estimated that these pelycosaurs (it is not a dinosaur) had a length of about 11.5 feet (3.5 meters), and weighed about 550 pounds (250 kg). This reptile had both mammal and reptile characteristics. Exhibit at "The Dinosaur Place", Montville, Connecticut, USA. Photo by Flo Bruehl September 30, 2006. Interpretation of Stegosaurus, a herbivorous reptile of the Late Jurassic Period. It is estimated that these dinosaurs had a length of about 26-30 feet (8-9 meters), about 9 feet (2.75 meters) tall, and weighed about 6,800 pounds (3,100 kg).

It is estimated that these dinosaurs had a length of about 20 feet (6 meters), and weighed on the order of 650-1,000 pounds (300-450 kg.). Exhibit at "The Dinosaur Place", Montville, Connecticut, USA. Photo by Flo Bruehl September 30, 2006. Interpretation of Stegomus, a prehistoric relative of the crocodile of the Triassic Period. It is not a dinosaur. They are characterized by heavy armor plates that cover the neck, back, trunk, and tail. They reach a length of about 9 feet.

It is estimated that these dinosaurs had a length of about 9 feet (2.8 meters). They were a very lightly-built dinosaur that could run rapidly. Fossilized stomach remains have been found containing small reptiles, fish, and other (smaller) Coelophysis indicating that it was a cannibal.

It is estimated that these dinosaurs had a length of about 6.5-8 feet (2-2.5 meters) and were estimated to weigh 65-150 pounds (30-70 kg.).
