A lobe-finned fish shelters in a crevice on a tropical Devonian reef. Gogonasus andrewsae was a foot-long predator of the tetrapodomorph group, the lineage of bony-fishes that include (amongst other things) the tetrapods. The superbly preserved fossils of this fish represent a priceless opportunity to examine the anatomy of a primitive tetrapodomorph and to gauge how the ancestors of terrestrial vertebrates (including us) may have developed.
As yet, only the head and girdles or this fish have been published, the proportions and scale count in this picture are however (hopefully) accurate as they are based on first hand observation of the unpublished postcranium. I was there in 2005 when Professor Tim Senden of ANU found the first complete Gogonasus in Paddys Valley.
John Long: "Fuck! Its a complete Gogonasus!!!"
The Gogo Formation of Northwestern WA is world famous for it's incredible fossil preservation - fish skeletons are 100% complete, in full articulation, uncrushed and often with soft-tissue traces.
