Ravasaur

The ravasaurs are large, raptor-like dinosaurs. The ones in Un'Goro are highly intelligent, volatile, and have a sense or code of conduct. Lar'korwi is the most dangerous. In Taur-ahe, its name means "Sharp Claw," but that does not do him justice. The ravasaurs of Zandalar are more distinct from raptors than the Un'Goro breed are, with crests of feathers on their heads and tails.

Ravasaurs may be common throughout other lands than just Un'Goro, as they are common troll companions alongside raptors.

The females produce an awful smell from a gland in their heads that allow males to know they are ready to breed.

The venomhide ravasaurs are extremely deadly, with poisonous blood, poisonous spit and even poisonous skin. Attempting to mount one without first building up a resistance to their toxins will result in death only a few hours later.

Baby ravasaurs apparently grow very quickly. Larger than other raptor infants, ravasaur hatchlings grow into towering reptilian beasts capable of massive devastation. Venomhide hatchlings are vicious and must be trained from the moment they hatch.

The ravasaurs of Zandalar have strong stomach linings and are able to eat nearly anything.

As a mount

 * Whistle of the Venomhide Ravasaur is a reward from They Grow Up So Fast (Horde), the final quest in a long chain involving raising a ravasaur hatchling in Un'Goro Crater. It is the Horde equivalent of the Alliance's Reins of the Winterspring Frostsaber.
 * Gilded Ravasaur is a part of the Digital Deluxe Edition and Collector's Edition of World of Warcraft: Battle for Azeroth.

As a companion pet
Ravasaur Hatchling can be looted from Ravasaur Matriarch's Nest in Un'Goro Crater.

Notes and trivia

 * Un'Goro Crater's ravasaurs are displayed as being much larger than regular raptor mobs, sometimes twice, thrice or even four times as large.
 * The Ravasaur is a unit in StarCraft II: Heart of the Swarm.
 * Ravasaur mounts are the same size as raptor mounts, even though the size difference between ravasaurs and raptors in the wilds is quite substantial.

Speculation
The wording in Coming of Age implies that ravasaurs are considered a completely separate species from raptors, despite both sharing the same model.
