Finally, publication on a fantastic find of nearly complete fossils of
the Cretaceous bird Gansus. However, to say that this amphibious waterfowl
is a good model for the ancestor of modern birds is a very risky
Not only are cladistic trees of early ornithuromorphans extremely
unstable, but Gansus is a relatively specialized, foot-propelled bird (much
like grebes and loons which were once classified close together and near the
based of modern birds). And add to that the poor fossilization potential of
terrestrial birds compared to that of littoral birds and waterfowl.
Anyway, here is a link to the abstract of the paper. It's a great
fossil find, but it is not a new taxon and I think it's evolutionary
importance is being overly hyped:
