这具古盗龙化石被认为是“缺失的一环”，并被认为是继始祖鸟之后证明鸟类确实是从某种食肉恐龙进化而来的最好证据。据报道，它来自中国的早白垩世地层，这些地层产生了鸟类和灭绝的非鸟类恐龙之间的其他壮观化石。但考古盗龙被发现是一个伪造品，其中一个原始鸟类和一个不会飞的驰龙科恐龙的骨头已经结合在一起。在这里，我们使用高分辨率X射线计算机断层扫描（CT）来确定伪造的性质和程度，以及它是如何建立的，通过成像整个标本的断裂模式和材料的分布。
TheArchaeoraptorfossil was announced as a 'missing link' and purported to be possibly the best evidence sinceArchaeopteryxthat birds did, in fact, evolve from certain types of carnivorous dinosaur. It reportedly came from Early Cretaceous beds of China that have produced other spectacular fossils transitional between birds and extinct non-avian dinosaurs,. ButArchaeoraptorwas revealed to be a forgery in which bones of a primitive bird and a non-flying dromaeosaurid dinosaur had been combined,,. Here we use high-resolution X-ray computed tomography (CT) to determine the nature and extent of the forgery, as well as how it was built, by imaging the fracture pattern and distribution of materials through the entire specimen.
