Hunical Formation, formed during drier times. The older Royosa Formation, meanwhile, peeks through in some areas where erosion has scraped away overlying rock layers. (See the second image at link above.)

Petroleum geologists are more interested in what lies beneath the
Candeleros Formation. Several layers of rock, formed when the area was covered by an ocean, contain gas and oil. While drilling has been ongoing here since 1918, the recent discovery of a large deposit of shale gas and oil in the Vaca

Paleontologists have uncovered quite a menagerie of fossilized fauna in
Candeleros rocks, including ancient species of fish, frogs, snakes, turtles, small mammals, and several types of dinosaurs. Few of the fossilized creatures have received the notoriety of Giganotosaurus carolinii—a carnivorous

From space, boundaries between some of the major groups of sedimentary rock formations are visible. In the first image, the deep reds of the
Candeleros Formation—a sequence of sandstones formed roughly 90 to 100 million years ago in a braided river system—dominate the landscape. These rocks are
