Check out Pharyngula on the new paper that uses penguin fossils to time the evolution of living bird groups. In October I posted this picture of a reconstruction of the penguin in question, which now has a name: Waimanu. I'd just add to PZ's run down that this fossil is also important because it is part of the transition from flying ancestors to flightless living penguins. Its wings could still bend at the elbows.

Two fossils recently discovered in Peru reveal that early penguins responded differently to natural climate change than scientists would have predicted. The larger skull, Icadyptes salasi (top), would have been fearsome to encounter…
We haven't had enough fossil penguins here, so let me rectify that deficiency. Below the fold you'll find a reconstruction of Waimanu, a 61-62 million year old penguin that was discovered in New Zealand.
