Crouching

Pressing the crouch key (default Ctrl) allows most terrestrial dinosaurs to crouch. Crouching offers several important benefits: Your footfalls and passive sounds are quieter, you have a lower profile, your turn radius is decreased, and you no longer leave a scent trail. As well, the scent ability will not highlight a crouching dinosaur. Crouching can be a critical tool to use during certain scenarios where turn radius is key, or when attempting stealth.

Not all dinosaurs can crouch; Apatosaurus, Lurdusaurus, and Parasaurolophus cannot use the crouch ability. Lurdu simply can't crouch, though Para has an alternate ability to switch between quadrupedal and bipedal, instead. Apato walks backward when 'crouching'. The other bonuses do not apply when these two dinosaurs utilize their abilities.
