Cyclothems are sequences of deposits interpreted as alternating between marine and terrestrial. The sediments in the photo are composed of Triassic limestones of the Dachstein Formation at Pass Lueg, Austria. For more details, see the Introduction to this gallery.
Red Rocks Amphitheater, west Denver --- Tilted layers of Fountain Formation are sand and conglomerate deposited from erosion of the ancestral Rocky Mountains.
Dinosaur footprints in the town of Torotoro. Torotoro is located in a valley formed by synclinal folding of sedimentary layers, forming a U-shaped regional structure. In the distance, one of the sides of the syncline can be seen, and the other occupies the bottom part of the photo, where the footprints are exposed
The Galapagos marine iguana ( Amblyrhynchus cristatus) is a reptile that is found exclusively on these islands and that feeds on algae. It can stay submerged up to a depth of 9 m, although it usually feeds in the intertidal coastal zone.
Cerro Blanco seen from the outskirts of the town of Ocucaje, Peru. These hills consist of layers of sandy, clay and diatomaceous sediments that contain fossils of marine vertebrates.
Thrust fault contact between the Eocene flysch (below) and the Permian Verrucano (above) near Schwanden. The arrow points to the fine contact line.
View looking up at the underside of a C unit in a Lofer cyclothem. The numerous bulbous forms which project downwards are called load casts. Load casts are often associated with turbidites. One bulb would be around 10-20 cm in diameter.
Garden of the Gods and Pikes Peak, Colorado Springs --- The red Lyons Formation sandstone layers were uplifted vertically when the Rocky Mountains were uplifted. The 14,000 foot Pikes Peak in the background is a lone Precambrian granite intrusion.
Panorama of the main site with dinosaur footprints in Torotoro National Park. This place is right at the entrance of the town of Torotoro. Most of the tracks are within a fenced area, which can be visited with local guides under the supervision of the National Park authorities.
The giant Galapagos tortoise ( Chelonoidis nigra) is the largest land turtle in the world. These vegetarian giants can reach a meter and a half in length and weigh more than 400 kilos.
