Diego grunted in Surprise, Then it was gone, disappearing in foliage.
Levine moved forward and crouched in the maid by the stream. He peered at the footprints left by the tiny animal. The footprints were three-toed, like the tracks of a bird. He saw more three-toed tracks, including some bigger ones, which were several inches across.
Levine had seen such prints before, in trackways such as the Purgatoire River in Colorado, where the ancient shoreline was now fossilized, the dinosaur tracks frozen in stone. But these prints were in fresh mud. And they had been made by living animals.
Sitting on his haunches, Levine heard a soft squeak coming from somewhere to his right. Looking over, he saw the ferns moving slightly.
He stayed very still, waiting.
After a moment, a small animal peeked out from among the fronds. It appeared to be the size of a mouse; it had smooth, hairless skin and large eyes mounted high on its tiny head. It was greenish-brown in color, and it made a continuous, irritable squeaking sound at Levine, as if to drive him away. Levine stayed motionless, hardly daring to breathe.
He recognized this creature, of course. It was a mussaurtis, a tiny prosauropod from the Late Triassic. Skeletal remains were found only in South America. It was one of the smallest dinosaurs known.
A dinosaur, he thought.
Even though he had expected I to see them on this island, it was still startling to be confronted by a living, breathing member of the Dinosauria. Especially one so small. He could not take his eyes off it. He was entranced. After all these years, after all the dusty skeletons – an actual living dinosaur!
The little mussaur ventured farther out from the protection of the fronds. Now Levine could see that it was longer than he had thought at first. It was actually about ten centimeters long, with a surprisingly thick tail. All told, it looked very much like a lizard. It sat upright, squatting on its hind legs on the frond. He saw the rib cage moving as the animal breathed. It waved its tiny forearms in the air at Levine, and squeaked repeatedly.
Slowly, very slowly, Levine extended his hand.
The creature squeaked again, but did not run. If anything it seemed curious, cocking its head the way very small animals do, as Levine’s hand came closer.
Finally Levine’s fingers touched the tip of the frond. The mussaur stood on its hind legs, balancing with its outstretched tail. Showing no sign of fear, it stepped lightly onto Levine’s hand, and stood in the creases of his palm. He hardly felt the weight, it was so light. The mussaur walked around, sniffed Levine’s fingers. Levine smiled, charmed.
Then, suddenly, the little creature hissed in annoyance, and jumped off his hand, disappearing into the palms. Levine blinked, unable to understand why.
Then he smelled a foul odor, and heard a heavy rustling in the bushes on the other side. There was a soft grunting sound. More rustling.
For a brief moment, Levine remembered that carnivores in the wild hunted near streambeds, attacking animals when they were vulnerable, bending over to drink. But the recognition came too late; he heard a terrifying high-pitched cry, and when he turned he saw that Diego was screaming as his body was hauled away, into the bushes. Diego struggled; the bushes shook fiercely; Levine caught a glimpse of a single large foot, its middle toe bearing a short curving claw. Then the foot pulled back. The bushes continued to shake.
Suddenly, the forest erupted in frightening animal roars all around him. He glimpsed a large animal charging him. Richard Levine turned and fled, feeling the adrenaline surge of pure panic, not knowing where to go, knowing only that it was hopeless. He felt a heavy weight suddenly tear at his backpack, forcing him to his knees in the mud, and he realized in that moment that despite all his planning, despite all his clever deductions, things had gone terribly wrong, and he was about to die.

“When we consider mass extinction from a meteor impact,” Richard Levine said, “we must ask several questions. First, are there any impact craters on our planet larger than nineteen miles in diameter-which is the smallest size necessary to cause a worldwide extinction event? And second, do any craters match in time a known extinction? It turns out there are a dozen craters this large around the world, of which five coincide with known extinctions. .
