在对加拿大自然博物馆保存了75年的两副角龙骨骼化石进行研究时,英国古生物学家尼克-朗里奇博士吃惊地发现,这两副骨骼的主人竟然是未知的新种恐龙,它们生活在7500万年前的北美洲。这副恐龙骨骼的主人在此之前被认定为准角龙和开角龙,都是加拿大的恐龙种群。根据朗里奇博士的研究发现,它们与美国西南岸的恐龙之间血缘关系更近,说明它们是新种群。朗里奇表示其中一副骨
In his study of two horned keel fossils preserved for 75 years at the Canadian Museum of Natural History, British paleontologist Dr. Nick Longing was surprised to find that the hosts of both skeletons were unexpectedly new species of dinosaurs, living 75 million years ago in North America. The masters of this group of dinosaur bones were previously identified as quinciarons and open-angle dragons, all of which are Canadian dinosaurs. According to Dr. Longridge’s research, they found that they are more closely related to dinosaurs on the southwestern shores of the United States, indicating that they are new populations. Longridge said one of the bones
