everything from the texture of the soil (firmly packed, but free of the pebbles so common in post-glacial tills), to the plants (hardwoods, lots of flowers, and a rich ground covering of ferns), to the sky (the clear bowl of earlier had given way to great towering mounds of cumulonimbus, like models of the Grand Canyon done in cotton). A Stedicam on the roof fed images into a VCR installed where the glove compartment would normally be, supplementing the images from our clip-on Micro-Cams. Also on the roof, various instruments recorded atmospheric information and strained the air for pollens that we could bring back to the twenty-first century.
After an hour, we had the most extraordinary bit of luck. There was a bend in the path where the ceratopsian herd had changed the course of its stampede to avoid a dense stand of conifers. We sailed around the curve and almost collided with what could only have been a Tyrannosaurus rex. It was easily double the size of the tyrannosaurs we’d seen the first night; a female of late years, a giant truly worthy of the name king — or queen — of the tyrant lizards.
Klicks hit the brakes. The beast, a dozen meters long, was flopped on its belly, torpid. It was apparently resting after having gorged itself on meat, for its muzzle was caked with drying blood. The giant warty head lifted from the soil and turned to face us. Rex had broad cheeks and fair binocular vision, its eyes gray and wet like pools of mercury. It let out a halfhearted roar, but it didn’t seem to feel any need either to run from us or, thankfully, to attack us. Klicks cut the Jeep’s engine and we sat there, about twenty meters away, drinking in the sight of this, the greatest hunter ever to stalk the Earth.
Some had suggested that tyrannosaurus was a scavenger, but I’d always rejected that idea. There are no purely terrestrial scavengers in the time of humans, since only birds and fish have the ability to search enough real estate to profitably find dead animals. Besides, Rex’s dagger-like teeth and bunching jaw muscles would have been unnecessary just to pick at carrion. Still, there was no carcass anywhere that we could see. I wondered why the beast wouldn’t have just taken a snooze at the site of the kill, but, after watching for a few minutes, the answer became obvious.
First one, then another, then finally a small flock of tiny yellow-and-green winged reptiles descended from the sky. They may well have been there earlier, but had been scared off by the arrival of our Jeep. The tyrannosaur opened its jaw, peeling back its thin scaly lips. Its teeth ranged from about seven centimeters long to maybe sixteen. Gobbets of flesh were crammed around the gums and fibrous pieces of meat were caught between adjacent teeth. Several of the bantam pterosaurs, wings half-folded, waddled into the great mouth and proceeded to peck at the remains of the carnosaur’s meal, cleaning its teeth and gums. One of the yellow-and-green flyers plucked out a particularly large hunk of meat and two of his friends began trying to grab it away from him. Rex snoozed on, indifferent to the squabble going on inside its gaping mouth. Other pterosaurs landed on its short back and thick tail, their beaks nipping in and out of the leathery skin like surgeon’s lances, rooting out worms and beetles that infested the predator’s hide.
This was clearly a familiar symbiosis for the tyrannosaur: we could hear a contented rumbling coming from deep in its chest. Heavy with its latest meal, Rex must have marched quite some distance from where it had killed its prey, since the pterosaurs would have had much richer pickings going over such a carcass.
We watched for over an hour, the heat mounting in the cab. Although the roof camera and our MicroCams were getting it all anyway, Klicks and I each brought still cameras to our faces and snapped off roll after roll of slides.
