Peru geologists strive to preserve whale cemetery - (An archeologist is seen cleaning the fossilized jaw of a whale in the Ocucaje desert, 310 km south of Lima. Once submerged but now situated some 30 kilometers from the shore, the area has been shaken by volcanic eruptions, killing off all life forms, according to experts from the country's geology and mining institute Ingemmet.

North American tectonics during the Early Cretaceous (125 Ma) Two large arms of the rising sea are about to converge, held up temporarily by tectonic barriers such as the Trans-Continental Arch and the Ouachita Uplift. Ocean basins, inherently deeper, are designated as dark blue: whereas, shallow epicontinental (epeiric) basins and continental shelves are light blue.

Turbidites (graywacke & shale) of the late Ordovician Martinsburg Fm, Edinburg Gap, western Massanutten Range, greater Shenandoah Valley, Virginia.  Bedding is slightly flexed from moderately-dipping to more steep, and then back to moderate again. Slickensides on the top of some exposed layers indicate the beds shifted slightly relative to their upstairs and downstairs neighbors: an example of folding through flexural slip. Cleavage here dips to the left, at a steeper angle than bedding.

Huaridelphis raimondii, with an outline of the head and potential fish prey. Miocene of Peru (16 mya).  Belongs to Squalodelphinidae, a rare extinct family of marine dolphins, which are related to the extant Ganges and Indus river dolphins. Image credit: © G.Bianucci.

The dusty Pisco-Ica desert stretches along the coast of southern Peru, but more than 16 million years ago it may have been covered with sparkling water and home to a now-extinct family of dolphins, known as squalodelphinids, according to new findings.
