The primates and the eagles of doom

One of the most intricate illustrations I have done recently is not about extinct species (not yet at least!). It shows the diversity of primates at the Tai Forest Reserve in Ivory Coast, West Africa. There are 8 different species of monkeys in that forest and, as scientists have found after years of field research, all of them are regular prey for the most impressive raptor in the area: the African crowned eagle. There are also 3 species of strepsirhine primates there (shown in the lower left corner), but their nocturnal habits keep them off the eagle´s menu.

I created this panoramic view of Tai forest for Clark Larsen´s masterly textbook “Our Origins”.

Hominids (humans and chimpanzees) live in in Tai forest as well but they are generally not attacked by the raptors. In the distant past, however, our own hominid ancestors were indeed part of the eagles’ diet, as shown by the marks in the skull of the famous Taung child, a young individual of Australopithecus africanus described as a new species by Raymond Dart back in the 1920s. It justly became one of the most important early findings in the study of human evolution, but the fact that it had fallen prey to an eagle would not be discovered until much later. In 1995 Ron Clarke and Lee Berger suggested that the accumulation of primate bones at the site of Taung could have been the result of the raptor’s activity, and the in 2006 Berger published a study of damage to the bone which revealed the bird’s talon marks on the hapless child’s skull.

I drew this impression of the Taung child’s sad end for Alan Turner’s and my book “Evolving Eden” in 2004. A couple of years later, Berger’s study of the marks in the child’s skull would confirm the raptor’s role in its death.
