Alberta Hilda Dinosaur Mega-Bonebed
The site is important because it confirms that Centrosaurus was a herding dinosaur, and documents that the herds were larger than previously thought, numbering well into the thousands.

Early land plants have long been known from Eastern Canada, thanks to pioneering work by Sir J. William Dawson, father of Devonian palaeobotany and principal of McGill University from 1855 to 1893. But this record poorly represented the earliest phase of land colonization.

Origins Lava tube caves, an important minor class, are formed by channelled outflow of molten lava in congealing flows. Sea caves most commonly result from erosion by waves.

The main objective of the multidisciplinary expedition was to carry out a geological survey of the ridge. Researchers, therefore, brought a veritable geotechnical arsenal to bear on the polar ice to gather seismic, gravimetric, bathymetric and other data.

Coal is a fossil fuel that has been used as a source of energy in Canada since the 18th century. Canada is home to 0.6 per cent of the world’s coal resources. Most of the country’s coal reserves (over 95 per cent) are found in Alberta, British Columbia and Saskatchewan. In recent years, the environmental movement has opposed the coal industry for disrupting local ecosystems, creating adverse health effects and for its large contribution to the carbon-dioxide emissions that drive climate change. In an effort to curb harmful emissions, the federal government has signalled its intention to phase out traditional coal-fired electricity by 2030, and Alberta has a plan to achieve the same goal as a province.

The CYPRESS HILLS and Swift Current Plateaux of southwestern Saskatchewan preserve Eocene, Oligocene, and Miocene FOSSILS 42 million to 16 million years old, in the Cypress Hills Formation. Faunas of at least 14 different ages are represented there.

Drumlin, smooth, half egg-shaped or ellipsoidal hill which formed beneath Quaternary GLACIERS. Drumlins [Gaelic druim, "hill"] were first described in Ireland. They lie parallel to the direction of ice movement, the blunt (stoss) end facing up-glacier, the lee sloping down-glacier.
