Septencoracias is an extinct genus of bird related to modern rollers and other Coraciiformes such as kingfishers, bee-eaters, motmots, and todies.
[1] It was found in the Fur Formation of Denmark, dating back to the Ypresian of the Lower Eocene Epoch, about 54 million years ago.
It is much larger than modern day rollers and its sister taxon Primobucco, more similar in size and proportion to kingfishers, motmots, and bee-eaters.
[2] The only fossil specimen of Septencoracias does not preserve the sternum and shoulder girdle, except for the left scapula, which is not bifurcated as in Late Eocene and later rollers.
The specimen only consists of an isolated tarsometatarsus, however it resembles that of Septencoracias in both size and shape more than any other fossil Coraciiformes, although it is slightly larger.
[2] Tyto Colius Harpactes Septencoracias Primobucco Eocoracias Paracoracias Geranopterus Coracias Atelornis Baryphthengus Todus Merops Alcedo Dacelo Nystalus Pteroglossus Picoides Bucorvus Upupa Phoeniculus Septencoracias is the oldest known member of the Coraciiformes, so it shows that this group was already fairly diversified by the Early Eocene, following the end-Cretaceous extinction.
Given the warmer climate of the Eocene, the finding of Septencoracias in Denmark indicates that the range of early Coraciiformes was much wider within the Northern Hemisphere during this time, due to the increased number of suitable habitats.
[2] This was part of a much broader trend in which many modern bird clades that were formerly found in higher latitudes during the Eocene are now restricted to the tropics and subtropics from cooling climates.
