石蝇(昆虫纲：长翅目)的分离、现存分布可以(主要)由超大陆联合古陆的分裂引起的替代来解释，也可以(主要)由多次灭绝来解释。从中国东北的早白垩世开始，赵氏华鲨被指定为目前生活在南半球的一个亚目，南极目，这支持了提出的“灭绝”的假设。然而，我们对这一物种的调查表明，它实际上属于Systellognatha，一种广泛存在的石蝇种群。
The disjunct, extant distribution of stoneflies (Insecta: Plecoptera) can be explained either (mainly) by vicariance resulting from the splitting of the super-continent Pangaea, or (mainly) by multiple extinctions. The assignment of Sinosharaperla zhaoi, from the Early Cretaceous of north-eastern China, to a suborder currently inhabiting the southern hemisphere, Antarctoperlaria, supported the proposed 'extinction' scenario. However, our investigation of this species demonstrates that it actually belongs to the Systellognatha, a widespread group of extant stoneflies.
