"In the gloom of the trees there seemed a constant menace and as we looked up into their shadowy foliage vague terrors crept into one's heart. It is true that these monstrous creatures which we had seen were lumbering, inoffensive brutes which were unlikely to hurt anyone, but in this world of wonders what other survivals might there not be--what fierce, active horrors ready to pounce upon us from their lair among the rocks or brushwood?"
--Sir Arthur Conan Doyle, The Lost World
