Giant Bony-toothed Birds

In the past decade the giant bird Pelagornis has been studied more often than in the previous century. Three new species have been named in eight years and the two most prominent papers on the internet are from the past three years. One of those papers, Fitzgerald et al. 2012, describes a set of remains from Australia that constitutes the first group of remains of Pelagornis discovered in Australia. More recently there have been studies conducted on the growth of  the characteristic pseudoteeth of Pelagornis. The structure of the pseudoteeth are described in detail. That structure is rather intriguing and makes for a very interesting read.
