Fossil Friday: The Explosive Origin of Flying Reptiles in the Mid … – Discovery Institute
This Fossil Friday features the gliding reptile Sharovipteryx mirabilis from the Mid Triassic of Central Asia.
Within only two million years of the Mid-Triassic era (about 230-228 million years ago) there was a sudden appearance of a large diversity of gliding and flying reptiles, such as Sharovipteryx with wings on the legs, Mecistotrachelos and the unrelated Kuehneosauridae with a gliding membrane across lateral rib-like projections, Longisquama with long feather-like scales on the back, and the earliest pterosaurs such as Preondactylus with bat-like wings supported by a single enlarged finger.
Considerable Re-Engineering
All these very different solutions for gliding and active flight required considerable re-engineering of the tetrapod body plan, and such biological novelty arguably required new and highly specific genetic code. Such specified information cannot be produced by blind mechanisms and certainly not in such a short window of time of only two million years, which…
