The First Tetrapod - Tiktaalik

It's especially difficult to identify the first true tetrapod, given gaps in the fossil record and a blurring of the lines dividing lobe-finned fish from "fishapods" from true tetrapods. Tiktaalik lived during the late Devonian period (about 375 million years ago); its skeletal structure was more advanced than the lobe-finned fish that preceded it (such as Panderichthys), but less articulated than more advanced tetrapods like Acanthostega. It's as good a candidate as any for the first fish that crawled up out of the primordial ooze on four stubby legs!
