Success?

When Jake regained consciousness a number of hours later, the spectacle before his eyes was very different from his last memory.

Goodbye rabid hyenas and angry T-Rex. Instead, a desolate landscape had replaced them. The corpses of many other animals were scattered all over the place, more or less undamaged, wherever he looked.

A sort of wildebeest with sharp teeth dangled with its tongue hanging on a high branch above it. Blood beaded down his skull with the regularity of a clock.

A bird of prey with a wingspan of about five meters was nothing more than a disarticulated mass of flesh and bone at his feet, such as a kite that would have crashed into a mountain with the force of a hurricane.

Twenty meters behind him was a massive dinosaur, about fifteen meters long, with most of its teeth and half of its ribs missing, and it had long since stopped breathing.
