Carnosaur (1984) is a horror novel written by Australian author John Brosnan, under the pseudonym of Harry Adam Knight. A film adaptation was made in 1993 by Adam Simon.
The novel bears several similarities to Michael Crichton's Jurassic Park, though Carnosaur preceded the latter work by six years. Brosnan feared that the public would have thought that his Gollancz reissue of Carnosaur would have been seen as a plagiarism to Jurassic Park. He admitted he liked the scene in the Crichton novel film adaption involving dinosaurs rampaging through a museum, as it bore direct similarities to an incident featured in Carnosaur.
Plot
Set in a rural village near Cambridgeshire, England, the novel opens at a chicken farm which is attacked one night by a mysterious creature, leaving both the farmer and his wife dead. A story circulates that the killer was a Siberian tiger that had escaped the private zoo of an eccentric lord named Darren Penward. A reporter named David Pascal investigates the carnage, and notices that the blood-stained room where the attack occurred has been thoroughly cleansed in a seeming attempt at covering the killer's footprints. A few days later, the creature attacks a stable, killing a horse, the keeper, and her daughter, leaving one survivor, an eight-year-old boy. Pascal arrives at the scene, only to find Penward's men already there, towing a concealed animal with a helicopter. Pascal interviews the boy, who reveals that the killer was not a tiger, but in fact a dinosaur. After unsuccessfully trying to interview Penward's men, Pascal moves on and begins a sexual relationship with Penward's nymphomaniac wife, who eventually takes him into her private quarters.
From there, Pascal enters the zoo, only to discover that it's filled with dinosaurs. He is captured and given a tour of the establishment. He sees a variety of different species, mostly carnivores, including the dinosaur that had escaped earlier which is identified as a Deinonychus, a sexually-frustrated Megalosaurus, and an adolescent Tarbosaurus. Penward explains that he recreated the dinosaurs by studying the DNA fragments found in fossils, then using them as a basis for restructuring the DNA of chickens. He goes as far as saying that he intends to let his dinosaurs loose in remote areas of the world where they could flourish and eventually spread after what he considers an inevitable Third World War. Pascal is imprisoned, only to be rescued by Lady Penward, but only after promising that he permanently commit to her. As they make their escape, Pascal notices that his ex-girlfriend Jenny Stamper, also a reporter, has been caught in the act of infiltrating Penward's zoo as well. Enraged at his insistence on helping her, Lady Penward releases the dinosaurs and other animals present in the zoo. In the chaos, the Tarbosaurus destroys Penward's helicopter and heavy machine gun before it can get in the air. The Deinonychus pursues Pascal and Jenny through Penward's museum, with the two getting away when it is tricked into attacking its own reflection due to perceiving it as a threat much like a bird. The Tarbosaurus, driven by equating the smell of mammals with easy food, further destroys the premise by bashing down numerous fences and gates, chasing the protagonists down before battling a pride of lions. The couple manage to reach Pascal's car and flee the property, with the Tarbosaurus in pursuit down the road. Sir Penward is gored in the leg by an escaped bull (one of several he kept as food for the dinosaurs) and captures his insane wife.
