Is it any wonder that the best place in the world for preserving ancient bones is the same place where the most/oldest are found?
The soil is so acidic in my area that soldiers buried during the Civil War have already disappeared...no traces of them remain in their graves.
6 million, 6 thousand. What’s the diff.
Did they find a Sally Struthers fossil trying to save them?
I have a question based on ignorance not foolishness?
How can bones be preserved after 3 - 5 million years when they are exposed to the elements and not preserved as the egyptians preserved their dead?
Wouldn’t the bones simply dissolve away b/c they are exposed to the elements, especially after 3 - 5 million years?
This may help explain where Barbara Boxer comes from.
Isn't everything evos find "crucial" since they have so many gaps to fill?
“This is a major finding that could create two new gaps in human evolution,”
This guy works for the Cleveland Museum of Natural History. The article makes it sound like it was a total Ethiopian deal. There were scientists from The Cleveland Museum of Natural History, the Addis Ababa University, Case Western Reserve University (Cleveland), and Berkeley Geochronology Center.

(Also, Donald Johanson was the curator of the museum when he discovered “Lucy” back in 1974.)

Early Volcano Victims DiscoveredWhole communities of ape-like creatures may have been killed in East Africa 18 million years ago by the once active volcano Kisingiri. Proconsul lived in a semi-arid environment close to the mountain and the research suggests they may have been caught by a pyroclastic flow. The abundance of the hominoid fossils may represent "death assemblages" - whole populations wiped out simultaneously by "glowing cloud" eruptions. The fossils of the Rusinga Formation form a crucial link between the early primates of the forest habitats, and human forerunners of the more open-country habitat, who lived in drier conditions than had been supposed, on a landscape that experienced repeated volcanic eruption.

Footprints to Fill:The case for A. afarensis as the Laetoli trailblazer hinges on the fact that fossils of the species are known from the site and that the only available reconstruction of what this hominid's foot looked like is compatible with the morphology evident in the footprints. But in a presentation given at the American Association of Physical Anthropologists meeting in April, William E. H. Harcourt-Smith of the American Museum of Natural History and Charles E. Hilton of Western Michigan University took issue with the latter assertion.
Flat feet and doubts about
makers of the Laetoli tracks

The prints show that whoever made them had a humanlike foot arch, and the reconstructed A. afarensis foot exhibits just such an arch. So far, so good. The problem, Harcourt-Smith and Hilton say, is that the reconstruction is actually based on a patchwork of bones from 3.2-million-year-old afarensis and 1.8-million-year-old Homo habilis. And one of the bones used to determine whether the foot was in fact arched--the so-called navicular--is from H. habilis, not A. afarensis.
