Similarly, paleontologists originally dubbed Oviraptor the "egg thief" because the first specimen was found over what was thought to be a Protoceratops nest.

同样，古生物学家以前一直认为，窃蛋龙性喜偷蛋，因为它们的第一块化石就出土于原角龙的巢穴中。

Here are two:"The known fossil record fails to document a single example of phyletic evolution accomplishing a major morphologic transition and hence offers no evidence that the gradualistic model can be valid," says Stephen Stanley , evolutionary paleontologist.

一个是 Stephen Stanley ，进化古生物学家，他的观点是：&已知的化石记录无法提供哪怕是一个实例来证明说物种的进化曾经完成过某种主要的形态变迁，因此也就没能为那种渐进模型的有效性提供任何证据。&
