Paraceratherium
Paraceratherium is an extinct genus of hornless rhinoceros. It is one of the largest terrestrial mammals that has existed and lived from the early to late Oligocene epoch (34–23 million years ago). The first fossils were discovered in what is now Pakistan, and remains have been found across Eurasia between China and the Balkans. It is classified as a member of the hyracodont subfamily Indricotheriinae. Paraceratherium means "near the hornless beast", in reference to Aceratherium, the genus in which the type species A. bugtiense was originally placed. The exact size of Paraceratherium is unknown because of the incompleteness of the fossils. The shoulder height was about 4.8 metres (15.7 feet), and the length about 7.4 metres (24.3 feet). Its weight is estimated to have been about 15 to 20 tonnes (33,000 to 44,000 lb). The long neck supported a skull that was about 1.3 metres (4.3 ft) long. It had large, tusk-like incisors and a nasal incision that suggests it had a prehensile upper lip or proboscis (trunk). The legs were long and pillar-like. The lifestyle of Paraceratherium may have been similar to that of modern large mammals such as the elephants and extant rhinoceroses. Because of its size, it would have had few predators and a slow rate of reproduction. It was a browser, eating mainly leaves, soft plants, and shrubs.
Saurophaganax
Saurophaganax ("lord of lizard-eaters") is a genus of large allosaurid dinosaur from the Morrison Formation of Late Jurassic (latest Kimmeridgian age, about 151 million years ago) Oklahoma, United States.[1] Some paleontologists consider it to be a junior synonym and species of Allosaurus (as A. maximus). Saurophaganax represents a very large Morrison allosaurid characterized by horizontal laminae at the bases of the dorsal neural spines above the transverse processes, and "meat-chopper" chevrons.[2] The maximum size of S. maximus has been estimated at anywhere from 10.5 meters (34 ft)[3] to 13 meters (43 ft) in length,[4] and 3 metric tons (3.3 short tons)[3] to 4.5 metric tons (5.0 short tons) in weight.[5] In 2020, it was estimated at 3.5-3.8 tons, with a minimum average weight of 2.6 tons and a maximum average weight of 4.7 tons.
