Description
Ambush Attack (Ex) If a plesiosaurus successfully hits a foe with its bite attack in the surprise round, it inflicts an additional 1d6 points of damage and threatens a critical hit on an 18–20. The additional damage from the ambush attack itself is precision damage and is not multiplied on a successful critical hit.
While not technically a dinosaur, the plesiosaurus is often found in waterways and swamps where dinosaurs and other megafauna are common. Long-necked and swift, these ambush predators prefer to dart in, bite a foe, and then swim away to hide while they wait for their victim to bleed out before swimming back to feed. Numerous species of this creature exist, from marsh-dwelling varieties to creatures that spend their entire lives at sea.
A plesiosaurus measures 11 feet long, though nearly half of this length is neck, and weighs 1,000 pounds.
Digmaul–Dinosaur Dinosaur, Troodon This small, slender-necked dinosaur’s bright, inquisitive eyes seem to miss nothing.
