Reconstrucción de T. carnifex 20 May 2016 Jose manuel canete

This large mammal somewhat resembles a maneless lion, yet it is built more like a bear. Dark stripes run perpendicular to its spine and down its long, muscular tail like that of a kangaroo.

Thylacoleo carnifex, or “pouched lion executioner”, is the largest of the marsupial lions. Although smaller than a smilodon, its thick bones, heavy musculature, and powerful jaws make it more than a match for the deadliest of big cats.

A thylacoleo is at least 2-1/2 feet tall at the shoulder, over 6 feet long and weighs 220 to 350 pounds.

Marsupial lions are ambush predators. The thylacoleo is a hypercarnivore, built for killing. Its retractable, switchblade like claws sink into prey while its powerful jaws, strong enough to crush a human skull, finish the job.

Augmented Critical (Ex): A marsupial lion’s bite threatens a critical hit on a natural attack roll of 18–20, dealing triple damage on a successful critical hit.

Improved Grab (Ex): To use this ability, a marsupial lion must hit with its bite attack. It can then attempt to start a grapple as a free action without provoking an attack of opportunity. If it wins the grapple check, it establishes a hold and deals automatic bite damage each round.

Pounce (Ex): If a marsupial lion charges, it can make a full attack.

Skills: A thylacoleo has a +4 racial bonus on Balance, Hide, and Move Silently checks. *In areas of tall grass or heavy undergrowth, the Hide bonus improves to +12.
