Cautiously he scrambled around among the high black stones, casting the search light beams before him and holding the Winchester always ready in his hand while trying to recall snatches of palaeontology studied at college long years ago.
"Yes, it must be a survival of one of the carnivorous dinosaurs," he decided, then paused, increasingly conscious of that steady thudding noise. What caused it?
t last he found himself before the creature's gigantic and repulsive head which lay limp over a blood bathed stone, huge jaws partially open, and serrated rows of wicked, stiletto-sharp teeth gleaming yellowly in the flashlight's rays. The head in shape was bullet-like, ending in a blunt nose as big as a bushel basket and in two prominent nostrils. The green, lidless eyes were still open, shining faintly, and seemed to follow his movements, but the steaming blood poured with the force of a small hose from between triple row of bayonetlike teeth that curved inward like those of a shark, to splash and bubble freely to the rock floor and to dribble horribly over the warty, gray hide.
Then Nelson discovered an amazing fact. About the great scaly neck, thick as a boy's waist, was fastened a ponderous collar, set with short, sharp spikes.
Nelson gasped. "What in hell!" he cried. "This damn thing's somebody's property!" His mind, staggered at the thought of dealing with a race that could and would domesticate such a hideous monster. "Well, it's no use standing here," he muttered, wiping the sweat from his eyes. "This isn't getting poor Alden away from those devils."
Thud! thud! In the act of turning he paused, listened once more. Then he discovered to his amazement that the heart of the apparently dead reptile was still beating strongly. He could even see the yellow skin of its belly rise and fall. The effect was grotesque, uncanny.
"Of course," muttered the shaken aviator, "I'd forgotten a reptile's ganglions will keep on beating for hours, like that shark we killed off Paumotu. Its heart didn't stop for five hours."
