“Or megalosaurus,” said Summerlee.

“Exactly. Any one of the larger carnivorous dinosaurs would meet the case. Among them are to be found all the most terrible types of animal life that have ever cursed the earth or blessed a museum.” He laughed sonorously at his own conceit, for, though he had little sense of humor, the crudest pleasantry from his own lips moved him always to roars of appreciation.

“The less noise the better,” said Lord Roxton, curtly. “We don’t know who or what may be near us. If this fellah comes back for his breakfast and catches us here we won’t have so much to laugh at. By the way, what is this mark upon the iguanodon’s hide?”

On the dull, scaly, slate-colored skin somewhere above the shoulder, there was a singular black circle of some substance which looked like asphalt. None of us could suggest what it meant, though Summerlee was of opinion that he had seen something similar upon one of the young ones two days before. Challenger said nothing, but looked pompous and puffy, as if he could if he would, so that finally Lord John asked his opinion direct.
