1. abelisaurus and Aelozavry
Abelisaurus
Abelisaurus - «Lizard Abel»
Time Habitat: Late Cretaceous (74-70 million. BP)
Food: carnivore
Length: up to 9 meters
Height: up to 3 meters
Weight: 1, 5 tons of
Speed:
Detected: Argentina, India, Madagascar
2. alioramus
Alioramus - «Another branch»
Time Habitat: Late Cretaceous (71-65 million. BP)
Food: carnivore
Length: 6 meters
3. Allosaurus
Allosaurus - «Another Raptor»
Time Habitat: Late Jurassic (153-135 million BP.)
Food: carnivore
Length: 12 meters
Height: up to 5 meters
Weight: up to 2 tons
4. Apatosaurus
Apatosaurus - «False Raptor»
Time Habitat: Late Cretaceous (154-145 million BP.)
Food: herbivore
Length: up to 24-26 meters
Weight: 40 tons
5. velociraptor
Velociraptor was a relatively small dinosaur, reaching lengths of 1, 8 meters, a height of 60 cm and a weight of about 20 kilograms [1]. The elongated skull length of 25 cm was bent upwards. Both the upper and the lower jaw there for 26-28 teeth spaced and curved back, which is an adaptation to capture and hold prey
6. Giganotosaurus
Giganotosaurus (lat. Giganotosaurus) - a giant carnivorous dinosaurs of the Cretaceous period. It belongs to the family of carcharodontosauridae, close to Allosaurus. Described R. Corea in 1995, nearly complete skeleton of an early Cenomanian (early Late Cretaceous, 93-89 million years ago) from the formation of the Rio Limay near Neuquen, Argentina. Along the length of the body (13, 2 m) exceeded Tyrannosaurus rex, a little behind Spinosaurus.
7. Gorgonopsid
8. Daspletozavry and Triceratops
Daspletozavry (Daspletosaurus (Russell, 1970)) - genus of carnivorous dinosaurs of the Cretaceous period tyrannosaurid family.
Reconstruction
Being very large in relation to modern predators Daspletozavr was not the largest of tyrannosaurid. Adults can reach a length of 8-9 meters with a head and a tail. The average weight of the dinosaur was about 2, 5 tons, ranging from 1 to 8 3, 8 tons. Daspletozavra skull was massive, it could reach up to 1 meter in length.
Triceratops - a sort of fossil herbivorous dinosaurs from the family of horned (Ceratopsidae), who lived at the end of the Late Cretaceous (65-70 million years ago) in North America. Length Triceratops reached 9 meters and height - 3 meters. According to scientists, the approximate weight of a dinosaur was up to twelve tons
9. Kaydzhiangozavr and Yanduzavry
10. Lioplevradon
11. Pahirinozavr
Pahirinozavry ("Tolstonosy lizard") - a genus of dinosaur-ceratopsians that lived during the Late Cretaceous (early Maastrichtian) in North America. They were herbivores, reaching up to 7 meters in length and about 4 tons of weight. They had horns, massive skull and bony protrusions, the largest of which were located in front of like a rhinoceros. The head of the dinosaurs reached 1, 4 meters in length
12. Sfenakodon
Sfenakodon (Sphenacodon) - large predatory pelycosaur Early Permian age. It resembles the well-known dimetrodon, but did not have such a developed dorsal "sail". However, the spinous processes are quite long. Type species - S. ferox - described by Charles O. Marsh in 1878. In 1937, A. Romer described a second species - S. ferocior. Both species are found in pozdnekarbonovyh sfenakodonov - Early Permian sediments (formation of Abo / Cutler, about 285-288 million years ago) New Mexico. Sphenacodon ferox reached 177 cm in length and has a low spines. The second kind, Sphenacodon ferocior was much larger (up to 2, 25 m long) and bulkier. He has a short "sail". The second type is marked for higher horizons of the formation. Undoubtedly, sfenakodon was the main predator of its time and place. He lived in the swampy forests and could eat other terrestrial vertebrates
