Black Caiman - Melanosuchus niger
The black caiman, Melanosuchus niger, is a crocodilian. It is a carnivorous reptile that lives along slow-moving rivers and lakes, in the seasonally flooded savannas of the Amazon basin, and in other freshwater habitats in South America. The black caiman has a bony ridge over brown eyes, and black, scaly skin. The skin coloration helps with camouflage during its nocturnal hunts, but may also help absorb heat (see thermoregulation). Mothers on guard near their nests are tormented by blood-sucking flies that gather around their vulnerable eyes leaving them bloodshot. The black caiman is one of the largest reptiles. It is the largest predator in the Amazon basin and possibly the largest member of the family Alligatoridae. Most adult black caimans are 3 to 4.26 metres (9.8–14 ft) in lengths, with old males rarely growing larger than 5 metres (16 ft). The black caiman broadly overlaps in size with the American alligator, although it is on average larger at maturity. In some areas (such as the Araguaia River) this species is consistently reported at 4 to 5 metres (13–16 ft) in length, much larger than the alligator (which rarely even reaches 4 meters), although specimens this size are uncommon. Several unconfirmed sources report that the black caiman can grow to 6 metres (20 ft) or more. It is, however, the third largest crocodilian in South America behind the American Crocodile and Orinoco Crocodile.
Concavenator corcovatus
Concavenator is a genus of theropod dinosaur that lived approximately 130 million years ago during the early Cretaceous period (Barremian stage). The type species is C. corcovatus; Concavenator corcovatus means "hump backed hunter from Cuenca". The fossil was discovered in the Las Hoyas fossil site of Spain by paleontologists José Luis Sanz, Francisco Ortega and Fernando Escaso from the Autonomous University of Madrid and the National University of Distance Learning. Concavenator was a medium-sized (roughly 6 meters (20 feet) long, and 500 kg (1,100 lbs) primitive carcharodontosaurian dinosaur possessing several unique features. Two extremely tall vertebrae in front of the hips formed a tall but narrow and pointed crest (possibly supporting a hump) on the dinosaur's back. The function of such crests is currently unknown. Paleontologist Roger Benson from Cambridge University speculated that one possibility is that "it is analogous to head-crests used in visual displays", but the Spanish scientists who discovered it noted it could also be a thermal regulator.
