Lusotitan

Introduction:
Lusotitan is a playable higher-tier herbivore and is the single largest creature in the game both in general size and strength.

In the Game:
While obviously incredibly slow as many sauropods were, Lusotitan is not a threat to be messed with for any creature unless you have a large amount of strategization. It has the highest health and damage of any creature in the game. It is planned to have a special attack called Stomp which involves it somewhat rearing up before coming down and forcing the entirety of it's body weight down effectively smashing anything directly below it and shattering bone in the process.

In Real Life:
Lusotitan was a large brachiosaurid originating from Portugal during the Late Jurassic period. It would have lived right alongside creatures like Allosaurus (the species europeaus, not the species maximus that is included in the game), Ceratosaurus, Lourinhaosaurus, Torvosaurus, Dacentrurus, Dracopelta, and more.

Trivia:

 * While the model hasn't been physically changed since it's release, it's countershading used to be a shade of orange during the closed alpha instead off the light brown it currently is.
