Dinosaur

Behemoths (bee-HEM-uthz or bee-HEE-muthz, also known as dinosaurs or thunderers ) were a group of ancient reptilian creatures found on Toril.

Description
Behemoths came in many shapes and sizes though, as their name implied, the best known were typically very large. Behemoths could be either herbivorous or carnivorous, depending on the species. Unlike dragons, behemoths were incapable of speech and were non-intelligent by nature.

Behemoths came in many varieties, from small to large, but most shared a number of physical features. Behemoths were, for instance, all covered in a layer of pebble-like skin. Most also demonstrated a well-developed sense of smell, which predatory behemoths used to hunt. Many were also herbivorous.

Psychology
Like dragons, predatory behemoths had a powerful lust to hunt, their razor-sharp teeth suitable for rending prey apart and were also highly territorial. Herbivorous behemoths were usually less aggressive although when defending their young or wounded or after being startled or irritated, they could be vicious enemies

History
It was widely believed by scholars from Candlekeep that behemoths existed in Toril since before the time period known as the Days of Thunder. In those ancients times, various species of behemoths thrived until a cataclysm changed the world so drastically that most of the behemoths went extinct.

Sages from Candlekeep didn't had a unified theory about the nature of the catastrophe. The most commonly accepted theory proclaimed this catastrophe was the Tearfall, while detractors of this theory believed that the sun temperatures diminished to a degree that produced a global climatic change so harsh that only the smallest behemoths were able to survive. A lunatic sage even proclaimed the cataclysm was actually a war between the gods and their enemies.

Whatever the truth, only a handful of behemoths, among them the proto-dragons, were able to survive and evolve into the members of the species that existed in the present age.

Habitats
Behemoths often lived in areas very much isolated from humanoid habitation. They usually were found in remote mountain valleys, isolated rocky plateaus, dense tropical island forests, or secluded in the deepest and darkest of the jungles.

Location
Behemoths were known to exist on Toril in Chult and Malatra. They could also be found on the island of Lurath, by way of time portals into Toril's distant past.

Species
There were multiple species of behemoths, some of which are listed below.

 * Macetail behemoth
 * Macetail behemoths were extremely territorial behemoths, covered in natural armor from head to toe.


 * Megaraptor
 * Superficially similar to deinonychus, though much larger, megaraptors were notable for their large hand claws.
