Gouges in the ground are best evidence yet of dinosaur courtship

Dinosaurs may not have been lonely in love, according to new research published in Scientific Reports. An international team of scientists has discovered the first tangible evidence that dinosaurs engaged in courtship behaviors: parallel scrape marks up to about 1.8 meters long and 40 centimeters deep that were gouged in the ground during the Cretaceous.

Travels in Geology: Sedona: A journey to the edge of a supercontinent

Built upon crimson slopes studded with junipers and towering pines, surrounded by soaring red rock spires, and encircled by 800,000 hectares of pristine national forest, the central Arizona town of Sedona is widely recognized for its natural beauty, diverse recreational opportunities, flourishing art scene and its role as a hub of New Age healing.

Getting there and getting around Sedona

Although Flagstaff’s Pulliam Airport is located just 40 kilometers from Sedona, flights into Phoenix Sky Harbor International Airport, a two-hour drive to the south, are usually cheaper and have better connections. It is also possible to ride Amtrak’s Southwest Chief route to Flagstaff. To fully explore central Arizona, you will need a car; if you fly in, you can rent one at either city’s airport, in downtown Flagstaff or in Sedona.

Wormholes may limit landslides

When Emma Harrison, a graduate student at the University of Pennsylvania, began digging trenches in the Luquillos Mountains of Puerto Rico to study how the soil mantle responds to rapid changes in erosion, she couldn’t help but notice that the thick soils were chock-full of wriggling worms. Intrigued by the worms’ abundance and prodigious activity at her field site, Harrison wondered whether their presence could be influencing weathering and erosion in the Luquillos.

Getting there and getting around Cyprus

Cyprus has been populated for centuries by a mix of ethnic Greeks and Turks. Periodic ethnic tensions erupted into communal violence in 1963, leading to a Turkish invasion in 1974. Turkey has controlled the northern third of the island ever since. The Troödos Mountains, which host the ophiolitic rocks, rise in the center of the island, within the Republic of Cyprus.

Travels in Geology: Cyprus: Island of Oceanic Crust

The soul of Cyprus, the third-largest island in the Mediterranean, lies in the Troödos Mountains — a rare, intact sliver of ancient oceanic crust that played a pivotal role in the development of plate tectonic theory. But don’t miss the Neolithic, Roman and Byzantine ruins, or the stunning beaches.

Northern Cyprus' "Peace Water" Pipeline

With its semi-arid climate and growing population, Cyprus suffers from the highest level of water stress in Europe and is ranked in the top five most water-stressed countries in the world, according to the World Resources Institute. Demand in the larger southern Republic of Cyprus is predicted to increase to 314 million cubic meters per year by 2020, up from 266 million cubic meters in 2004.
