Harlan's Ground Sloth - Paramylodon harlani
Paramylodon is an extinct genus of ground sloth of the family Mylodontidae endemic to North America during the Pliocene through Pleistocene epochs, living from around ~4.9 Mya–11,000 years ago. It is also known as Harlan's ground sloth. Paramylodon measured about 3 m (9.8 ft) in length and weighed up to 1,000–1,089 kg. It is known from North America deposits, including in Mexico and the United States and as far south as Guatemala, and often mistaken as Glossotherium. Currently there is just one recognized species, P. harlani, (Owen) 1840, which is commonly referred to as Harlan's ground sloth in honor of American paleontologist Dr. Richard Harlan, who first discovered and described a lower jaw in 1835. Paramylodon exhibits the interesting characteristic of having had dermal ossicles, small bones embedded in the skin, presumably adding a degree of protection to the animal. This characteristic is also shared by the South American Mylodon.
Prestosuchus chiniquensis
Prestosuchus (meaning “Prestes crocodile”) is an extinct genus of South American pseudosuchians in the family Prestosuchidae. Its close relatives include Saurosuchus and Postosuchus. Like other related prestosuchids, Prestosuchus had a deep skull and serrated teeth. Prestosuchus lived during the Middle Triassic in what is now Brazil. Initially it was estimated to be around 5 meters (17 feet) but a specimen discovered in 2010 suggest that Prestosuchus reached lengths of nearly 7 meters (23 feet) making it one of the largest rauisuchians alongside Saurosuchus and Fasolasuchus. Weight estimates range from 500 to 1,600 kg. While it resembled a dinosaur in having a large body and upright posture, it was actually a rauisuchian archosaur, more closely related to modern crocodilians.
