He paused a few yards from the creature, and took out his camera. Immediately, the pilot of the helicopter came up alongside him, pushing his hand down. "No permitado."

"What?"

"I am sorry, senor. No pictures arc allowed."

"Why the hell not?" Levine said. He turned to Guitierrez, who was trotting down the beach toward them. "Marty, why no pictures? This could be an important - "

"No pictures," the pilot said again, and he pulled the camera out of Levine's hand.

"Marty, this is crazy."

"Just go ahead and make your examination," Guitierrcz said, and then he began speaking in Spanish to the Pilot, who answered sharply and angrily, waving his hands.

Levine watched a moment, then turned away. The hell with this, he thought. They could argue forever. He hurried forward, breathing through his mouth. The odor became much stronger as he approached it. Although the carcass was large he noticed there were no birds, rats, or other scavengers feeding on it. There were only flies - flies so dense they covered the skin, and obscured the outline of the dead animal.

Even so, it was clear that this had been a substantial creature, roughly the size of a cow or horse before the bloat began to enlarge it further. The dry skin had cracked in the sun and was now peeling upward, exposing the layer of runny, yellow subdermal fat beneath.

Oof, it stunk! Levine winced. He forced himself closer, directing all his attention to the animal.

Although it was the size of a cow, it was clearly not a mammal. The skin was hairless. The original skin color appeared to have been green, with a suggestion of darker striations running through it. The epidermal surface was pebbled in polygonal tubercles of varying sizes, the pattern reminiscent of the skin of a lizard. This texture varied in different parts of the animal, the pebbling larger and less distinct on the underbelly. There were prominent skin folds at the neck, shoulder, and hip joints - again, like a lizard.
