Pelagornis sandersi:  The Largest Flying Bird

Pelagornis sandersi is an extinct species of "bony-toothed" bird that lived in South Carolina approximately 25 million years ago. This species had a wingspan of 21 to 24 feet, making it the largest bird ever to have flown. In a paper in Proceedings of the National Academy of Sciences, I described this species and presented analyses of its potential flight capabilities. Models based on living birds suggest Pelagornis sandersi was an efficient long-distance flier similar to modern albatrosses.

Blink Films has brought Pelagornis sandersi back to live in a spectacular documentary titled "Top Ten Biggest Beasts Ever" for the National Geographic Channel.

Rise and Fall of African Penguins

Penguins have a complicated history in Africa. During the Pliocene, roughly five million years ago, four species occupied the Cape region.  In previous work, Dr. Daniel Thomas and I demonstrated that these species arrived separately, taking advantage of the South Atlantic Gyre to disperse from South America.  In a new study, we report Miocene African fauna over ten million years in age.  These fossils show another interval of high penguin diversity and point to sea level change as a cause of their eventual decline.  Only a single species lives in Africa today.

Ancient Penguins in the Modern World

Its always nice to share fossil penguins. Recently, a few of my favorite extinct penguin species have made it into the popular realm.  Kairuku waitaki and Kairuku grebneffi, two svelte species of giant penguins, are now featured on a $5 siver coin minted in New Zealand. Inkayacu paracasensis, a species known for preserving the oldest fossil penguin feathers, has meanwhile made it onto a stamp valued at 10 Peruvian nuevo sols.

Dig magazine, a fantastic kids archeology and paleontology magazine, recently published an issue on fossil penguins, with several articles written by myself and my students.

Marples (named after the New Zealand penguin paleontologists Dr. Brian Marples) is the Bruce Museum's 3D printed penguin - scanned and printed at life size from the Black-footed Penguin specimen in our collection.  While he is not quite fossil, he often helps promote penguin themed events at the museum.


Feather Evolution in Swifts and Hummingbirds

The Green River Formation is one of the most important fossil Lagerstätten worldwide.  The smallest fossil bird that has been described from the Green River is Eocypselus rowei, a primitive member of the lineage that leads to today’s hummingbirds and swifts. In a recent paper in, my co-authors and I reported details of the preserved feathers of this remarkable tiny bird.
