The Allosaurus (Allo) is a rare dinosaur in "The Ark Of Craft: Dinosaurs!" So, in turn, we don't know much about it. Its exact location(s) on the islands is very much unknown. However, we do know that its bites are strong enough to kill an unarmored player in 2 hits.
They appear to have black claws and nails. They also have a lime-green underbelly, and a cactus-green body. The crest, which sits atop the eyelid, is a bright red.
The Allosaurus will run at the player, covering the ground at a moderate pace. When it gets to close, it will almost "lunge" at the player.
