About this image

Macrophotograph of the tiny fossilised jaw of Bishops whitmorei, a placental mammal that flourished in Australia during the Early Cretaceous period about 115 million years ago. The classification of this and similar fossils has been governed by the assumed evolution of molar teeth in mammals. However, evidence from B. whitmorei suggests the existing understanding of this evolutionary trait may be incorrect and that many species have been incorrectly classified.
