Sinohydrosaurus/Hyphalosaurus & Epidendrosaurus/Scansoriopteryx

it's not a mesosaur...it's a lower cretaceous Chinese sinohydrosaurus lingyuanensis

A peculiar diapsid now officially called _Hyphalosaurus lingyuanensis_, as per Smith and Harris (2001).

Smith, J.B. and Harris, J.D. (2001). A taxonomic problem concerning two diapsid genera from the Lower Yixian Formation of Liaoning Province, China. Journal of Vertebrate Paleontology 21(2): 389-391.

And while on the topic of nomenclature, I came across this paper from last year:

Harris, J.D. (2004). "Published works" in the Electronic Age: recommended amendments to Articles 8 and 9 of the Code. Bulletin of Zoological Nomenclature 61(3): 138-148.

Harris argues (very convincingly, IMHO) that in the event that _Epidendrosaurus ningchengensis_ and _Scansoriopteryx heilmanni_ are demonstrated to be subjective synonyms, then the former name should get priority. However, this requires both pro- and retroactive changes to the current ICZN (as the title implies).
