Rhamphosuchus may have been the biggest when it was thought to be 49ft, but it is no small Crocodylian at 26-36 ft.
Either way it is very large and would have been an impressive sight.

Parahelelicoprion is a eugeneodontid, they are ancient relative of ratfish. For the image, the body almost looks like a shark but who exactly knows how the body of parahelelicoprion looked like. Indeed, at 26-36 ft, rhamphosuchus is no joke and would be terrifying.




Prionosuchus reaches a length of upto 9 m (30 ft), making it the largest amphibian that has ever lived. It has an elongated and tapered snout, numerous sharp teeth, long body, short legs, and a tail adapted for swimming. It's general appearance was very similar to a modern crocodile, particularly to the gharial, and it probably had a similar lifestyle as an ambush aquatic predator feeding on fish and other aquatic animals. 

Fossils have been found in South America (Brazil).




Gigantopithecus roamed the Earth 100,000 years ago. It is the largest ape that ever lived, standing about 1.8–2 m (5.9 – 6.6 ft) in height and weighed in the neighborhood of 180 – 300 kg. Large males may have had an arm span of 3.6 m (12 ft). It most likely walked on all fours as modern gorillas and chimpanzees, when it stood on it's hind legs, it was close to 2.8 m (9 ft) tall.

Fossils have been found in Asia (China, India, Indonesia, Thailand and Vietnam).
