Iterations and other stories (collection)

The tyrannosaur used its tiny forelimbs to keep its torso from sliding forward as it pushed with its powerful legs until it was standing.

Forward, thought Cohen. Forward!

The beast’s body felt different. Its belly was full to bursting.

Forward!

With ponderous steps, the rex began to march.

It was wonderful. To be in control again! Cohen felt the old thrill of the hunt.

And he knew exactly what he was looking for.

“Judge Hoskins says okay,” said Axworthy. “She’s authorized for you to be transferred into that new T. rex they’ve got right here in Alberta at the Tyrrell. It’s a young adult, they say. Judging by the way the skeleton was found, the rex died falling, probably into a fissure. Both legs and the back were broken, but the skeleton remained almost completely articulated, suggesting that scavengers couldn’t get at it. Unfortunately, the chronotransference people say that back-propagating that far into the past they can only plug you in a few hours before the accident occurred. But you’ll get your wish: you’re going to die as a tyrannosaur. Oh, and here are the books you asked for: a complete library on Cretaceous flora and fauna. You should have time to get through it all; the chronotransference people will need a couple of weeks to set up.”

As the prehistoric evening turned to night, Cohen found what he had been looking for, cowering in some underbrush: large brown eyes, long, drawn-out face, and a lithe body covered in fur that, to the tyrannosaur’s eyes, looked blue-brown.

A mammal. But not just any mammal. Purgatorius, the very first primate, known from Montana and Alberta from right at the end of the Cretaceous. A little guy, only about ten centimeters long, excluding its ratlike tail. Rare creatures, these days. Only a precious few.

The little furball could run quickly for its size, but a single step by the tyrannosaur equaled more than a hundred of the mammal’s. There was no way it could escape.

The rex leaned in close, and Cohen saw the furball’s face, the nearest thing there would be to a human face for another sixty million years. The animal’s eyes went wide in terror.

Naked, raw fear.

Mammalian fear.

Cohen saw the creature scream.

Heard it scream.

It was beautiful.

The rex moved its gaping jaws in toward the little mammal, drawing in breath with such force that it sucked the creature into its maw. Normally the rex would swallow its meals whole, but Cohen prevented the beast from doing that. Instead, he simply had it stand still, with the little primate running around, terrified, inside the great cavern of the dinosaur’s month, banging into the giant teeth and great fleshy walls, and skittering over the massive, dry tongue.

Cohen savored the terrified squealing. He wallowed in the sensation of the animal, mad with fear, moving inside that living prison.

And at last, with a great, glorious release, Cohen put the animal out of its misery, allowing the rex to swallow it, the furball tickling as it slid down the giant’s throat.

It was just like old times.

Just like hunting humans.

And then a wonderful thought occurred to Cohen. Why, if he killed enough of these little screaming balls of fur, they wouldn’t have any descendants. There wouldn’t ever be any Homo sapiens. In a very real sense, Cohen realized he was hunting humans— every single human being who would ever exist.

Of course, a few hours wouldn’t be enough time to kill many of them. Judge Hoskins no doubt thought it was wonderfully poetic justice, or she wouldn’t have allowed the transfer: sending him back to fall into the pit, damned.

Stupid judge. Why, now that he could control the beast, there was no way he was going to let it die young. He’d just—

There it was. The fissure, a long gash in the earth, with a crumbling edge. Damn, it was hard to see. The shadows cast by neighboring trees made a confusing gridwork on the ground that obscured the ragged opening. No wonder the dull-witted rex had missed seeing it until it was too late.

But not this time.

Turn left, thought Cohen.

Left.

His rex obeyed.

He’d avoid this particular area in future, just to be on the safe side. Besides, there was plenty of territory to cover. Fortunately, this was a young rex—a juvenile. There would be decades in which to continue his very special hunt. Cohen was sure that Axworthy knew his stuff: once it became apparent that the link had lasted longer than a few hours, he’d keep any attempt to pull the plug tied up in the courts for years.

Cohen felt the old pressure building in himself, and in the rex. The tyrannosaur marched on.

This was better than old times, he thought. Much better.

Hunting all of humanity.

The release would be wonderful.

He watched intently for any sign of movement in the underbrush.
