She stands at midday, the heat of the sun bothering her. Still, compared to many other animals she’s well off, her jaw flanges, long tail and horn dissipating heat and her black tear-like facial markings allowing her to see without being blinded. She lies against the ground, camouflages against the Pampas grass, her head scouting for appropriate prey.

She spots a potential candidate, a juvenile Adinotherium. Like her he has a horn, but his points forwards and is much thinner, a pure display device compared to her oddly shaped dome. He grazes, vaguely aware of her presence, but an infected hindleg prevents him from sprinting immediately. So he begins to pick up the pace, trying to join the rest of the herd.

She’s having none of that.

With a painful push-up like motion, she uses her forelimbs to dart forward, quickly followed by a kick from the hindlimbs. She’s now fully galloping, and quickly catches up to her victim. He begins running and manages to dodge her initial strike, but his leg prevents him from maneuvering too often, forcing him on a straight line.

This is all she needs, and a few paces is all it takes for her to ram against his flank, fully sending him rolling on the ground. Broken ribs elicit a bray, the notoungulate trying to get up but finding himself struck again by the sparassodont’s horn.

Repeated strikes bludgeon the struggling victim to the ground, too weak to fight back. Its now that his life will end.

Using her forelimbs to keep the Adinotherium in place, the Thylacosmilus begins digging her fangs on his belly, careful as to not cause too much stress on the base of her skull. Once they’re fully inside the screaming ungulate, she pushes back, erupting his abdomen and pulling out his digestive system. Fangs still stab his intestines, clawing them out of the body.

Using her muscular lips, she sucks the entrails, hideous slurps stopping only as her molars need to grasp them, preventing them from obstructing her throat. This happens relatively quickly, and within a few minutes the Adinotherium is disemboweled, his own guts inside her grotesquely expanded ones.

She quickly walks away, already spotting a Macroeuphractus running furiously towards her. The armadillo can have the bones and muscles, she’s done.
