Dinosaur, Coelophysis – The Hollow-Boned Stalker

A lithe, sinewy predator stretching nearly 10 feet in length, Coelophysis boasts a narrow, elongated skull brimming with serrated teeth. Its large, forward-facing eyes gleam with predatory focus, while its hollow bones and powerful hind limbs hint at a creature built for speed and agility. A long, whip-like tail aids in balance, and its clawed forelimbs are poised to snatch unsuspecting prey.

Behavior:
An opportunistic hunter, often operating in coordinated packs to overwhelm prey. While capable of solitary hunting, it exhibits a preference for group tactics, using swift, synchronized movements to encircle and isolate targets. Its keen senses and strategic approach make it a formidable foe in its environment.

Habitat:
Thriving in the arid floodplains and sparse woodlands of the Late Triassic, it favours regions with intermittent water sources and ample cover. It often establishes territories near riverbanks or within dry savannas, where prey is abundant and escape routes are plentiful.

Modus Operandi:
Employing a blend of stealth and speed, Coelophysis initiates hunts by silently tracking potential prey, then launching sudden, coordinated attacks. Its lightweight frame allows for rapid acceleration, and its sharp claws and teeth ensure a swift kill. In packs, it utilizes flanking maneuvers to confuse and corral victims, minimizing the chance of escape.

Motivation:
Driven by an insatiable hunger and a survivalist instinct, Coelophysis is perpetually on the hunt. Its pack-oriented nature fosters a competitive environment, where dominance is established through successful kills. This relentless pursuit of sustenance and status propels it to take calculated risks, making it both a cunning predator and a persistent threat to any creature crossing its path.

Coelophysis, also known as pokedesaurus, is a smaller carnivorous dinosaur, roughly equivalent to a reptilian wolf.

These creatures are usually 10 feet long, with almost half of that length being tail. They usually live in small packs, with solitary individuals usually being outcasts or young males seeking a mate. Sometimes, though, many packs will merge into an unstoppable horde of creatures, which eat anything in their path, including each other. After a few months of ravaging the wilderness, the horde disperses, sometimes because of some calamity killing all of its members, but sometimes with no loss of life to any of the coelophysises. Sages are still unsure of why this happens, as there is no obvious environmental trigger.

COMBAT

Coelophysises attack prey from ambush, knocking it down and nipping at its prone form. They shy away from any prey larger than themselves, and will not attack humans unless starved (or in a horde).

Trip (Ex): A coelophysis that hits with a bite attack may immediately make a trip attempt (+1 check modifier) as a free action without provoking an attack of opportunity. If the attempt fails, the opponent cannot react to trip the coelophysis.

Skills: A coelophysis has a +4 racial bonus on Hide, Listen, Move Silently, Spot and Survival checks.
