The Skull of Tiktaalik

The cranial endoskeleton of Tiktaalik roseae. 2008. J. Downs et al. Nature 455: 925-929.

Today, the team that discovered Tiktaalik in the Canadian Arctic provided new details of its transition from water to solid ground. Further examination of the fossils shows a coordinated series of changes underway not just in the creature's limbs, but in its crocodile-like skull, neck and gills, all helping prepare it for a less aquatic, shallow-water lifestyle.

The researchers published their results today in the journal Nature and discussed them publicly during a symposium at this morning's meeting of the Society of Vertebrate Paleontology meeting in Cleveland.

The SVP conference is progressing very well. I'll post some photos, etc., when I get a chance.
