Smooth-fronted Caiman - Caiman crocodilius
The smooth-fronted caiman (Paleosuchus trigonatus), also known as Schneider's dwarf caiman or Schneider's smooth-fronted caiman,[2] is a crocodilian from South America, where it is native to the Amazon and Orinoco Basins. It is the second-smallest species of the family Alligatoridae, the smallest being Cuvier's dwarf caiman, also from tropical South America and in the same genus. An adult typically grows to around 1.2 to 1.6 m (3.9 to 5.2 ft) in length and weighs between 9 and 20 kg (20 and 44 lb). Exceptionally large males can reach as much as 2.3 m (7.5 ft) in length and 36 kg (79 lb) in weight. The head of the smooth-fronted caiman is similar in appearance to that of the spectacled caiman (Caiman crocodilus), but no bony ridge or "spectacle" occurs between the eyes. The scutes on the back of the neck and the tail are large, triangular, and sharp. It has heavily ossified body armour on both its dorsal and ventral surfaces. The relatively short tail is broad at its base and flattened dorsoventrally in contrast to most species of crocodilians which have laterally flattened tails. The bony scutes on the tail have sideways projections; and the tail is so well armoured, that it is relatively inflexible. This caiman is a dark greyish-brown with mid-brown eyes. Males grow to about 1.7 to 2.3 m (5 ft 7 in to 7 ft 7 in) long, with the largest recorded specimen being 2.6 m (8 ft 6 in). Females do not often exceed 1.4 m (4 ft 7 in). It is a robust crocodilian, strong for its size, and tends to carry its head high with its neck angled upwards.

Dromaeosaurus albertensis
Dromaeosaurus (play /ˌdrɒmiːɵˈsɔrəs/) was a genus of theropod dinosaur which lived during the Late Cretaceous period (middle late Campanian), sometime between 76.5 and 74.8 million years ago, in the western United States and Alberta, Canada. The name means 'running lizard'. Dromaeosaurus was a small carnivore, about 2 m (6 ft 7 in) in length and 15 kg (33 lb) in weight. Its mouth was full of sharp teeth, and it had a sharp "sickle claw" on each foot. It lived during the Campanian stage of the Late Cretaceous, however, some fragmentary remains such as teeth which may belong to this genus have been found from the late Maastrichtian age Lance and Hell Creek Formations, dating to 65.5 million years ago. Dromaeosaurus had a relatively robust skull with a deep snout. Its teeth were rather large and it had only nine of them in the maxilla. In Dromaeosaurus albertensis, a vein at the back of the head, the vena capitis dorsalis, drains the front neck muscles through two long canals running to the posterior surface of the brain.
