Under concrete and asphalt, vestiges of a disappeared world still sleep. In Denver, a simple energy feasibility study was enough to recall it: a fragment of dinosaur vertebra, 67.5 million years old, was extracted from a deep drilling made in the parking lot of the Denver Museum of Nature and Science. While Colorado is known … Read more
Located off the northeast coast of Madagascar, Sainte-Marie island does not only appeal to its white sandy beaches and turquoise waters.
