Paleontologists Find Ancient Proteins in 18-Million-Year-Old Mammal Tooth Enamel
The Turkana Basin within the East African Rift System preserves fossil assemblages that date back more than 66 million years; Green et al. collected powdered samples for paleoproteomic analysis from the dense interiors of enamel from large herbivores from the Early Pleistocene back to the Oligocene (29 million years).

Paleontologists have discovered protein sequences within dense enamel tissues of ancient rhinocerotid and proboscidean fossils collected at sites of Buluk and Loperot in the Turkana Basin, Kenya.
