Dinosaurs Attack! is a trading card series by Topps released in 1988 and containing 55 base cards and 11 sticker cards. The cards tell the story of dinosaurs transported through time into the present day through a freak accident and wreaking havoc on Earth. The series is notable for its graphic violence and gore, intended to evoke memories of the successful Mars Attacks trading card series of 1962. Overview The Dinosaurs Attack! trading cards were created as a follow-up to the successful trading card series Mars Attacks. Like Mars Attacks, Dinosaurs Attack! was intended as a homage and a parody of 1950s B-movies. While Mars Attacks was a parody of alien invasion movies, Dinosaurs Attack! was inspired by monster-on-the-loose movies such as The Beast from 20,000 Fathoms and Godzilla. Topps veteran product developers Art Spiegelman, Len Brown (who had designed and written Mars Attacks) and Gary Gerani developed the idea for the series. It was Gerani's original suggestion, and he receives a single "created by" credit in later Topps-licensed comic books and graphic novels based on the property. Gerani sketched out the 55-card storyboards, wrote the copy for the card backs, and art directed all the cards. Herb Trimpe adapted Gerani's storyboards into pencils, with some assistance from John Nemec and George Evans. Then, Earl Norem and XNO delivered the final paintings. Paul Mavrides and Harry S. Robins of the Church of the SubGenius did the artwork for the 11 stickers. The storyline of the card series is minimal. They tell the story of a scientific time travel experiment gone horribly wrong, transporting several dinosaurs, pterosaurs, marine reptiles and other prehistoric animals of many kinds from their various prehistoric time periods into modern times, where they wreak havoc upon mankind. Most of the cards show a different scene of the dinosaurs causing chaos and death across the world. Some of the cards show the scientists frantically working to reverse the time travel effect. In the end, the Supreme Monstrosity, the patron deity of the dinosaurs (nicknamed "Dinosaur Satan" by some fans due to its resemblance to the popular culture depiction of Satan) intervenes, trying to stop the scientists. The lead scientist, Elias Thorne, sacrifices himself to the Supreme Monstrosity so his wife, Helen, can succeed and send the dinosaurs back to their own time, tearing the animals apart in the process. The artwork is intended to be shocking and graphically
