Machimosaurus Reconstruction

Machimosaurus Model

Machimosaurus is a reptile confirmed to appear in Additional Creatures: Aquaria.

Machimosaurus, meaning "Machimoi Lizard" after the Egyptian Machimoi, is a genus of large crocoyloforms that lived in the oceanic waters of what is now Europe and North Africa during the Late Jurassic, 150 million years ago. Machimosaurus, while looking like a crocodile, was actually part of a family of relatives called Thalassosuchians, which were a group of crocodile-relatives adapted to marine habitats. Some thalassosuchians took this to the extreme, with metriorynchids like dakosaurus baring flippers, a fluked tail, the ability to give birth to live young, and replacing the rough hide with smooth skin. Meanwhile teleosaurs, which Machimosaurus is a part of, were more traditional, often still moving and basking on land, being fairly similar to crocodiles with the exception of reduced limbs. Machimosaurus is known as the largest thalassosuchian to currently exist, being up to 7 meters long. It was a top predator, known to feed on other marine reptiles like turtles.

Machimosaurus littusrex, with littusrex meaning "coastal king", in Additional Creatures is said to be added as a large and aggressive creature, being similar in size to the ARK Additions Deinosuchus. It will be a hazard to newer players, as it will live on the island's coastlines. It will have the ability to swallow smaller creatures, including players, whole akin to the also planned Mawsonia. The taming method originally was planned to involve it swallowing a diplocaulus, which would have made the machimosaurus sickly, causing it to become temporarily stunned and able to be fed passively., with the taming being ruined if the player is too close to it when it recovers. However, this plan has been changed into something more simple. The Machimosaurus can be knocked out traditionally, but the torpor amount is rediculous high, making it practically not possible. Instead, swallowing diplocaulus will inflict it with a very high amount of torpor, which is correlated to the diplocaulus's HP.
