Carcharodontosaurids include some of the largest land predators ever known: Giganotosaurus, Mapusaurus, Carcharodontosaurus, and Tyrannotitan all rivaled Tyrannosaurus in size. Estimates give a maximum weight of 8–10 metric tons (8.8–11.0 short tons) for the largest carcharodontosaurids, while the smallest carcharodontosaurids were ...
Paraceratherium is one of the largest known land mammals that have ever existed, but its precise size is unclear because of the lack of complete specimens. [4] Its total body length was estimated as 8.7 m (28.5 ft) from front to back by Granger and Gregory in 1936, and 7.4 m (24.3 ft) by the palaeontologist Vera Gromova in 1959, [ 33 ] but the ...
With a length of around 2 m (6 ft 7 in) it was one of the biggest predators of Mallorca during the Early Pliocene. [277] The largest known blind snake is Boipeba tayasuensis with estimated total length of 1.1 m (3 ft 7 in). [278] The largest known land lizard is probably megalania (Varanus priscus) at 7 m (23 ft) in length. [279]
Size estimates of Mesonyx were used to generate the proposal that Andrewsarchus was the largest predatory land mammal that ever lived. Since Andrewsarchus is known only from a single isolated skull, the estimate of its size was based on scaling up material from Mesonyx.
“They are the only group of birds that achieved the role of terrestrial apex predators, evolving species that basically conquered South America during the Miocene (about 23.03 million to 5.33 ...
1912-15 — Spinosaurus is found in North Africa and is speculated to be the largest terrestrial predator that ever lived. 1920 — Andrew Douglass proposes dendrochronology (tree-ring dating). 1924 — Raymond Dart examines fossils of "Taung Child," found by quarrymen in South Africa, and names Australopithecus africanus.
