"In 1924 a plateau was discovered in the jungles of eastern Bangladesh, and it was thought at the time that a possible 'lost world' had been found, inspiring hopes driven by a still-lingering fascination with the ideas behind Arthur Conan Doyle's 1912 novel. In fact researchers at the time were unfortunately close to the truth, and a number of extant relatives of otherwise extinct animals still existed (though to say thrived may be to put too fine a point on it). Their survival was concluded to be due to certain radioactive leakings from a myriad of vents and geysers across the plateau, which had given the creatures the necessary resilience to death to weather the dramatic shifts in climate, which otherwise brought about a number of catastrophic mass extinctions. It was not, however, a wondrous paradise that the researchers had stumbled into; many of the animals had grown fierce and highly intelligent across the generationsthe Necrosaur being a prime exampleand only one member of the party ever managed to make his unfortunate way out of the heavy jungles, to die with his body riddled with cancers in a hospital in Calcutta."
Creature-of-the-week again. Not especially inventive, it really is just a dinosaur with two heads, but the deadline loomed and I had fun nonetheless.
