"Hateg was an eastern European island that existed throughout most of the Cretaceous," Weishampel told Discovery News. "It was colonized by the dinosaurs, turtles, crocodiles and various other animals that lived in subtropical to temperate shallow marine environments." The new research suggests Hateg Island might have connected to mainland Transylvania at one point on the northeastern side, but scientists are still piecing together the region's geological history. What is clear, however, is that the dinosaurs must have evolved away from other parts of Europe, since such isolated groups tend to be smaller or larger than normal, due to condensed ecosystems that result in size extremes. On the Other End of the Scale A few years ago, two of Codrea's colleagues from Bucharest, along with French paleontologist Eric Buffetaud, described "a new giant pterosaur" from Cretaceous Transylvania that was "remarkable for its very large size and for the robustness of its large skull." The new pterosaur turned out to have a wingspan of 40 feet or more. Its scientific name, Hatzegopteryx thambema, appropriately means "Hateg Island Monster." The flying reptile's head alone was nearly 10 feet long. Its skull was so long that Buffetaud's team wondered how the creature could have ever taken flight, but the researchers discovered that thin bones enclosing small air pockets gave the monster "strength and lightness." Recreations of Hateg Island now therefore take on quite a psychedelic dream-like picture, with dwarf Transylvania dinosaurs living in relative tropical splendor, while flying monstrous reptiles swoop overhead. Codrea explained that the pterosaur originally came as "an intruder, a visitor arrived from far away areas," and could fly over large distances that prevented it from locking into the island miniaturizing pattern of evolution. The Baron's Tragic Ending Baron von Nopsca did not live to see his theories validated. He embarked on a motorcycle tour of Italy and Europe with his lover and secretary, Bayazid Doda, an Albanian Muslim, seated in his sidecar. The two men ran out of money and cut their journey short in Vienna where, in a rage, the baron drugged Doda's tea to render him unconscious. He then shot Doda before turning the gun on himself in 1933 when he was 56 years old. Despite the baron's inner demons, other researchers now mostly support his theories, which included not only his work on dinosaurs, but also plate tectonics. Weishampel believes his work was so important that he's taken a year off to study it further and to write a related book. Codrea and his colleague are also still exploring Transylvania's dinosaurs. They plan to publish information on even more finds there soon. "I'm sure that Nopsca would be pleased about our discoveries, if he were alive," Codrea said. "He was an enthusiastic paleontologist and he believed in his research." He added, "Sometimes, when I'm in the field, I have the strange sensation that he is somewhere near…" Related Links: Discovery News blog: Born Animal |
