Tyrannosaurus

Tyrannosaurus (meaning "Tyrant Lizard") is a prehistoric creature that was included in the original Fossils and Archeology mod. As a large theropod dinosaur, the tyrannosaurus can grow to be 6.5 blocks tall and 11 blocks long in 12 Minecraft days. It can drop tyrannosaurus meat, tyrannosaurus teeth, leg bones, arm bones, rib cages, vertebrae, claws, feet, and skulls upon death. Like most other mobs in the mod, they do not spawn naturally in the world and must be created by the player.

BEHAVIOR
Adult tyrannosaurus are powerful creatures. They break through all blocks that are weaker than iron, making them very hard to contain. They cannot be hit with arrows or bare hands. They will hunt cows, pigs, Triceratops, Pachycephalosaurus, and Gallimimus, but only when hungry. Tyrannosaurus will also attack nearby allosaurus when hungry, but the battle is so evenly matched that either can win. Allosaurus are fast while tyrannosaurus are strong and have more health. When tyrannosaurus reach 12 days old, their eyes become red. When their health is brought below 8 hp, they will enter "sleep mode" and lie down.

Adult tyrannosaurus breed every 5 minutes. The breeding probability is determined by the amount of tyrannosaurus nearby.

TAMING
A tyrannosaurus must be at least 12 days old to be tamed. To tame one, the player must attack the tyrannosaurus until it is at 8 hp (4 hearts; this is easy to check with a DinoPedia). Strong armor and a good sword is recommended. The tyrannosaurus will then enter "sleep mode" and lie down. While it is asleep, the player must right click it with the scarab gem. It's eyes will no longer be red, signifying that it is tamed, and it will regain all it's heath. After being tamed, it can be ordered with a Skull Stick. A tutorial to this process can be found here.

RIDING
Tamed tyrannosaurus are rideable as adults. When ridden, they won't go hungry or age. Water deeper than two blocks causes the player to automatically dismount. It can be controlled only if the player holds a Whip. Riding uses the same WASD format as normal Minecraft movement.

FEEDING
Tyrannosaurus will kill and eat almost any animal when hungry, including allosaurus drops. They cannot be hand fed, but meat items can be tossed to them as food. They will eat from feeders.
