Boreortalis is our first probable Cracid! The Cracids are a group of distinctive chickeny dinosaurs such as the Currasow, Guans, and Chachalacas. Boreortalis is the oldest definite record of these dinosaurs, known from the Alachua Formation of Florida, as well as the Snake Creek Formation of Nebraska. As such, it lived from about 20.5 until 12 million years ago, from the Aquitanian until the Serravallian ages of the Miocene of the Neogene. It seems to be the most similar to the Chachalacas, a group of chickeny birds known from the southern United States, Mexico, and Central and South America. As it is known from fairly limited material, very little more can be said about it.
