"Heavy Claw" discovered in 1983 by amateur fossil hunter, William J. Walker in Surrey, England, described by Angela C. Milner & Alan J. Charig in 1986. Baryonyx lived during the Early Cretaceous Period about 130 to 120 million years ago. It was 12 meters (40 ft.) in length, 5 meters (16 ft.) in height, and 4 tons in weight.

"High Chested Arm Lizard" and was discovered in Utah and Colorado. This animal was also believed to have been the largest land-animal of all time, but lost that record to Sauroposeidon and the titanosaurs of South America. Brachiosaurus lived in the Late Jurassic Period and grew from 25 meters (82 feet) in length, 7 meters (23 feet) high at the hips; 15.5 meters (51 feet) high at top of the head, and weighed in at 90 tons.

"Elegant Jaw" discovered in the late 1850's in Bavaria, Germany by Dr. Oberndorfer & described by Johann A. Wagner in 1959. Compsognathus lived during the Late Jurassic Period about 150 to 140 million years ago. It was 1 meter (3 ft.) in length, 0.3 meters (1 foot) in height at the hips, & 7.7 pounds (3.5 Kilos) in weight, also worthy of note is that the JP3 Dinosaur guide disputes this size as it claims the animal was 1.5 meters (5 ft) in length and 0.6 meters (2 ft) in height. Compsognathus can be found on Isla Sorna as well as possibly Isla Nublar. Dr. Robert Burke, the Paleonotologist of the inGen Expedition to Isla Sorna in 1997, either mistook Compsognathus to be Procompsognathus triassicus or both genus are present on Sorna.

"Double-Crested Lizard" discovered in 1940 in Monument Valley in Arizona by Jesse Williams a Navajo Native American, described & named in 1970 by Samuel P. Welles. Dilophosaurus lived during the Early Jurassic Period about 200 to 180 million years ago. It was 6.8 meters (22 feet) in length, over 2 meters (7 feet) in height, & 1.100 pounds in weight.

"Chicken Mimic" discovered in 1963 in the Gobi Desert of Mongolia, described & named in 1972 by Halszka Osmólska, Ewa Roniewicz, and Rinchen Barsbold. Gallimimus lived during the Late Cretaceous Period about 75 to 70 million years ago. It was 4-6 meters (13-20 feet) in length, 2.5-3 meters (8-10 feet) in height, & 968 pounds (440 kilos) in weight.

"Herrera's Lizard" discovered in 1958 in San Juan, Argentina by Don Victorino Herrera, described & named by Osvaldo A. Reig in 1963. Herrerasaurus lived during the Late Triassic Period about 235 to 230 million years ago. It was 3.9 meters (almost 13 feet) in length, 2.3 meters (7.5 feet) in height, & 80 pounds in weight.

"Medium Spine Lizard" discovered in 1923 in Dorset, England by von Huene, described by C. A. Walker in 1964. Metriacanthosaurus lived during the Late Jurassic Period about 160 to 150 million years ago. It was 8 meters (26 ft.) in length, 3 meters (10 ft.) in height, and 2 tons in weight. The Metriacanthosaurus on Isla Nublar may be Yangchuanosaurus shangyouensis since it was thought to be a species of Metriacanthosaurus when inGen started cloning their dinosaurs

"Similar Saurolophus" found in Western North America and described by Parks in 1922. Parasaurolophus lived in the late Cretaceous about 76-65 Million years ago. It was 7-7.5 meters (23-25 ft.) in length, 4 meters (13 ft.) in height and weighed 4 tons.

"Before Ceratosaurus" discovered in 1910 in Glouchestershire, England, described & named by Friedrich von Huene in 1926. Proceratosaurus lived during the Middle Jurassic Period about 175 to 169 million years ago. It may have been 5 meters (15 ft.) in length, 2.10 meters (7 ft) in height, and 300 kilos. Proceratosaurus can be found on Isla Nublar, though never witnessed on the tour. It could be seen listed on the JP Brochure Map found in the Ford Explorer tour vehicles, and labeled on the embryo cold storage unit in the lab. Proceratosaurus may exist on Isla Sorna since inGen orginally cloned them there, though there is no evidence as of yet to prove that it still does.

"Segi Canyon Lizard" discovered in 1933 in Segi Canyon, Arizona & described by Dr. Charles L. Camp in 1936. Segisaurus lived during the Early Jurassic Period about 206 to 200 million years ago. It was 1.2 meters (4 ft.) in length, 0.6 meters (2 ft.) in height, & 3.5 pounds (7.7 Kilos) in weight.

"Roofed Lizard" discovered in Colorado in 1876 by M. P. Felch & described by Othniel C. Marsh in 1877. Stegosaurus lived during the Late Jurassic Period about 154 to 150 million years ago. It was 12 meters (40 ft.) in length, 5.8 meters (19 ft.) in height at the top of the plates, & 7 tons in weight.

"Three Horned Face" discovered in 1888 in Wyoming by John Bell Hatcher & described by Othniel Charles Marsh in 1889. Triceratops lived during the Late Cretaceous Period about 68 to 65 million years ago. It was over 10.5 meters (35 ft.) in length, over 4.5 meters (15 ft.) in height at the top of crest, & 7 tons in weight.

"Tyrant Lizard King" discovered in 1902 by Barnum Brown in Hell Creek, Montana. Tyrannosaurus was holder of the worlds largest carnivorous dinosaur before Spinosaurus and Giganotosaurus made their way onto the scene. Tyrannosaurus lived in the Late Cretaceous period and grew over lengths of 12 meters (40 feet), (42 feet recorded and held by "Sue"), 4 meters (13 feet) at the hips and 5 meters height (16 feet) at the top of head, & 6 to 8 tons in weight.

In reality, Velociraptor's name means "Swift Robber" and when it was first discovered it caused paleontologists to believe dinosaurs were warm blooded. Originally named Deinonychus and discovered in 1964, V. antirrhopus weighed 160 pounds (73 kilos) and was 4 meters (13 feet) in length and nearly 1.8 meters (6 feet) high.
