Where did hoatzins come from? These unusual birds, only one
species of which exists in South America today, originated in the Old World.
Studies of the oldest known fossils of Hoatzin ancestors have now shown that
these birds existed around 34 million years ago in Europe. Paleornithologists
at the Senckenberg Gesellschaft für Naturforschung and Flinders University in
Adelaide published their findings this week in the specialist journal
“Naturwissenschaften”.
