The Deepest Rocks Hold the Oldest Clues
The oldest rock layers are viewed as the deepest, implying fossils within formed earliest. Yet exact dating remains impossible because natural processes like rain frost wind and erosion distort or destroy valuable research material.
Dippy the Dinosaur to Join Smithsonian Exhibition
The mounted Diplodocus skeleton nicknamed Dippy will star at the Smithsonian Institution in Washington. At 80 feet long and 12 feet high, it is the largest dinosaur specimen there, with a five-member team assembling the steel and wood framework. The bones were found in Utah’s Dinosaur National Monument and excavated over years by Carnegie Museum collectors.

Building Dippy the Diplodocus from scattered fossil remains
Paleontologists reconstruct extinct giants from partial bones and teeth. The process combines field excavation, careful packing, and extensive lab work to fit fragments into a complete skeleton, often using casts from other museums to fill missing parts.
