Fossil protection ordinarily consisted of a tarp over the site, and a trench around the perimeter to control water runoff. The question was how large a trench the velociraptor fossil required. To decide that, they were using computer-assisted sonic tomography, or CAST. This was a new procedure, in which Thumper fired a soft lead slug into the ground, setting up shock waves that were read by the computer and assembled into a kind of X-ray image of the hillside. They had been using it all summer with varying results.

Thumper was twenty feet away now, a big silver box on wheels, with an umbrella on top. It looked like an ice-cream vendor's pushcart, parked incongruously on the badlands. Thumper had two youthful attendants loading the next soft lead pellet.

So far, the CAST program merely located the extent of finds, helping Grant's team to dig more efficiently. But the kids claimed that within a few years it would be possible to generate an image so detailed that excavation would he redundant. You could get a perfect image of the bones, in three dimensions, and it promised a whole new era of archaeology without excavation.

But none of that had happened yet. And the equipment that worked flawlessly in the university laboratory proved pitifully delicate and fickle in the field.

"How much longer?" Grant said.

"We got it now, Alan. It's not bad."

Grant went to look at the computer screen. He saw the complete skeleton, traced in bright yellow. It was indeed a young specimen. The outstanding characteristic of Velociraptor-the single-toed claw, which in a full-grown animal was a curved, six-inch-long weapon capable of ripping open its prey-was in this infant no larger than the thorn on a rosebush. It was hardly visible at all on the screen. And Velociraptor was a lightly built dinosaur in any case, an animal as fine-boned as a bird, and presumably as intelligent.

Here the skeleton appeared in perfect order, except that the head and neck were bent back, toward the posterior. Such neck flexion was so common in fossils that some scientists had formulated a theory to explain it, suggesting that the dinosaurs had become extinct because they had been poisoned by the evolving alkaloids in plants. The twisted neck was thought to signify the death agony of the dinosaurs. Grant had finally put that one to rest, by demonstrating that many species of birds and reptiles underwent a postmortem contraction of posterior neck ligaments, which bent the head backward in a characteristic way. It had nothing to do with the cause of death; it had to do with the way a carcass dried in the sun.

Grant saw that this particular skeleton had also been twisted laterally, so that the right leg and foot were raised up above the backbone.

"It looks kind of distorted," one of the kids said. "But I don't think it's the computer."

"No," Grant said. "It's just time. Lots and lots of time."

Grant knew that people could not imagine geological time. Human life was lived on another scale of time entirely. An apple turned brown in a few minutes. Silverware turned black in a few days. A compost heap decayed in a season. A child grew up in a decade. None of these everyday human experiences prepared people to be able to imagine the meaning of eighty million years - the length of time that had passed since this little animal had died.

In the classroom, Grant had tried different comparisons. If you imagined the human lifespan of sixty years was compressed to an hour, then eighty million years would still be 3,652 years-older than the pyramids. The velociraptor had been dead a long time.

"Doesn't look very fearsome," one of the kids said.

"He wasn't," Grant said. "At least, not until he grew up." Probably this baby had scavenged, feeding off carcasses slain by the adults, after the big animals had gorged themselves, and lay basking in the sun. Carnivores could eat as much as 25 percent of their body weight in a single meal, and it made them sleepy afterward. The babies would chitter and scramble over the indulgent, somnolent bodies of the adults, and nip little bites from the dead animal. The babies were probably cute little animals.

But an adult velociraptor was another matter entirely. Pound for pound, a velociraptor was the most rapacious dinosaur that ever lived. Although relatively small-about two hundred pounds, the size of a leopard-velociraptors were quick, intelligent, and vicious, able to attack with sharp jaws, powerful clawed forearms, and the devastating single claw on the foot.

Velociraptors hunted in packs, and Grant thought it must have been a sight to see a dozen of these animals racing at full speed, leaping onto the back of a much larger dinosaur, tearing at the neck and slashing at the ribs and belly…

"We're running out of time," Ellie said, bringing him back.

Grant gave instructions for the trench. From the computer image, they knew the skeleton lay in a relatively confined area; a ditch around a two-meter square would be sufficient. Meanwhile, Ellie lashed down the tarp that covered the side of the hill. Grant helped her pound in the final stakes.

"How did the baby die?" one of the kids asked.

"I doubt we'll know," Grant replied. "Infant mortality in the wild is high. In African parks, it runs seventy percent among some carnivores. It could have been anything - disease, separation from the group, anything. Or even attack by an adult. We know these animals hunted in packs, but we don't know anything about their social behavior in a group."

The students nodded. They had all studied animal behavior, and they knew, for example, that when a new male took over a lion pride, the first thing he did was kill all the cubs. The reason was apparently genetic: the male had evolved to disseminate his genes as widely as possible, and by killing the cubs he brought all the females into heat, so that he could impregnate them. It also prevented the females from wasting their time nurturing the offspring of another male.

Perhaps the velociraptor hunting pack was also ruled by a dominant male. They knew so little about dinosaurs, Grant thought. After 150 years of research and excavation all around the world, they still knew almost nothing about what the dinosaurs had really been like.

"We've got to go," Ellie said, "if we're going to get to Choteau by five."

Hammond

Gennaro's secretary bustled in with a new suitcase. It still had the sales tags on it. "You know, Mr. Gennaro," she said severely, "when you forget to pack it makes me think you don't really want to go on this trip."

"Maybe you're right," Gennaro said. "I'm missing my kid's birthday." Saturday was Amanda's birthday, and Elizabeth had invited twenty screaming four-year-olds to share it, as well as Cappy the Clown and a magician. His wife hadn't been happy to hear that Gennaro was going out of town. Neither was Amanda.

"Well, I did the best I could on short notice," his secretary said. "There's running shoes your size, and khaki shorts and shirts, and a shaving kit. A pair of jeans and a sweatshirt if it gets cold. The car is downstairs to take you to the airport. You have to leave now to make the flight."

She left. Gennaro walked down the hallway, tearing the sales tags off the suitcase. As he passed the all-glass conference room, Dan Ross left the table and came outside.

"Have a good trip," Ross said. "But let's be very clear about one thing. I don't know how bad this situation actually is, Donald. But if there's a problem on that island, burn it to the ground."

"Jesus, Dan… We're talking about a big investment."

"Don't hesitate. Don't think about it. Just do it. Hear me?"

Gennaro nodded. "I hear you," he said. "But Hammond- "

"Screw Hammond," Ross said.

"My boy, my boy," the familiar raspy voice said. "How have you been, my boy?"

"Very well, sir," Gennaro replied. He leaned back in the padded leather chair of the Gulfstream II jet as it flew east, toward the Rocky Mountains.

"You never call me any more," Hammond said reproachfully. "I've missed you, Donald. How is your lovely wife?"

"She's fine. Elizabeth's fine. We have a little girl now."

"Wonderful, wonderful. Children are such a delight. She'd get a kick out of our new park in Costa Rica."

Gennaro had forgotten how short Hammond was; as he sat in the chair, his feet didn't touch the carpeting-he swung his legs as he talked. There was a childlike quality to the man, even though Hammond must now be… what? Seventy-five? Seventy-six? Something like that. He looked older than Gennaro remembered, but then, Gennaro hadn't seen him for almost five years.

Hammond was flamboyant, a born showman, and back in 1983 he had had an elephant that he carried around with him in a little cage. The elephant was nine inches high and a foot long, and perfectly formed, except his tusks were stunted. Hammond took the elephant with him to fund-raising meetings. Gennaro usually carried it into the room, the cage covered with a little blanket, like a tea cozy, and Hammond would give his usual speech about the prospects for developing what he called "consumer biologicals." Then, at the dramatic moment, Hammond would whip away the blanket to reveal the elephant. And he would ask for money.

The elephant was always a rousing success; its tiny body, hardly bigger than a cat's, promised untold wonders to come from the laboratory of Norman Atherton, the Stanford geneticist who was Hammond's partner in the new venture.

But as Hammond talked about the elephant, he left a great deal unsaid. For example, Hammond was starting a genetics company, but the tiny elephant hadn't been made by any genetic procedure; Atherton had simply taken a dwarf-elephant embryo and raised it in an artificial womb with hormonal modifications. That in itself was quite an achievement, but nothing like what Hammond hinted had been done.

Also, Atherton hadn't been able to duplicate his miniature elephant, and he'd tried. For one thing, everybody who saw the elephant wanted one. Then, too, the elephant was prone to colds, particularly during winter. The sneezes coming through the little trunk filled Hammond with dread. And sometimes the elephant would get his tusks stuck between the bars of the cage and snort irritably as he tried to get free; sometimes he got infections around the tusk line. Hammond always fretted that his elephant would die before Atherton could grow a replacement.
