Kronosaurus

***Kronosaurus marinus*** (name meaning "marine lizard of Kronos") is a species of short-necked pliosaur that originally lived during the Early Cretaceous period (Aptian to Late Albian) from the Toolebuc Formation (middle to late Albian) and Wallumbilla Formations (Aptian) of Queensland and New South Wales in Australia as an extinct species, *Kronosaurus queenslandicus*, and the genus itself was once extinct, but has since been brought back from extinction by SciiFii. *Kronosaurus marinus* was originally planned to be showcased in **Cretaceous Park** located in Sacramento, California, but many big zoos and safari parks from throughout the world commissioned SciiFii to buy many of their *Kronosaurus marinus* and have been exhibited in big zoos and safari parks worldwide ever since. With the length of 9 to 10.9 meters (30 to 36 feet), *Kronosaurus marinus* is among the largest pliosaurs, and is named after the leader of the Greek Titans, Kronos. Like other pliosaurs, *Kronosaurus marinus* is a marine reptile. It has an elongated head, a short neck, a stiff body propelled by four flippers, and a relatively short tail with a fin underneath. The posterior flippers are larger than the anterior. *Kronosaurus marinus* is carnivorous, and has many long, sharp, conical teeth. A feature of the genus *Kronosaurus* is that the first three maxillary teeth are enlarged to fangs. All Sauropterygians have a modified pectoral girdle that supports a powerful swimming stroke. *Kronosaurus marinus* and other plesiosaurs/pliosaurs have a similarly adapted pelvic girdle, allowing them to push hard against the water with all four flippers. Between its two limb girdles is a massive mesh of gastralia (belly ribs) that provides additional strength and support. *Kronosaurus marinus* is a fast and active swimmer. As an apex predator, *Kronosaurus marinus* primarily preys on other marine reptiles, including other plesiosaurs/pliosaurs and sea turtles, although it is known to prey on large cephalopods and fish, as well as scavenge off of carrion of other marine reptiles and mammals (such as whales). Despite its size and fearsome-looking appearance, *Kronosaurus marinus* does not prey on terrestrial mammals or live marine reptiles, and is a very active, playful animal in a manner similar to large dolphins such as killer whales, although is less intelligent due to its less brain power. *Kronosaurus marinus* is generally solitary and prefers to live alone throughout its life except during the breeding seasons. The gestation period of *Kronosaurus marinus* lasts around ten months and gives birth to either single or two babies at a time, which are cared for by their mothers for more than three years until they are subadults, and they are fully grown by the fourth year. *Kronosaurus marinus* can live to be around 70 years on average, although there are reports of individuals living around 80 years. Unlike (most) modern-styled cetaceans, *Kronosaurus marinus* is extremely tolerant to life in captivity and has low stress if properly cared for, making it a suitable animal for aquarium parks and a good replacement for killer whales in captivity, due to its adaptability to life in captivity and remain very docile, friendly, and playful towards humans and other sapient species.
