Reconstituição dos 1º invertebrados da fauna de Burgess Shale (600 milhões anos a.C. - Canadá).

The Glamorgan Heritage Coast of South Wales, U.K., formed millions of years ago when present day Wales was nearly completely submerged. These exposed, eroded early Lower Lias or early Jurassic rocks, primarily limestone and shale, are readily accessible to rock hounds and to people who simply enjoy strolling along the shore. The beach platforms, cliffs and sea caves (like this one) here are all quite spectacular both when viewed from the cliff-top paths and when exploring up close. Make sure to consult tidal charts before investigating the sea caves since this portion of the Welsh coast has a considerable tidal range - over 50 ft (16 m). Photo taken on July 20, 2011.

August GSA Today cover photo: The Three Sisters are iconic sandstone towers exposed above the Jamison Valley in the Blue Mountains, Australia. Erosion in the mountains is dominated by stream channels cutting through exposed joints and preferential erosion of weaker shale units interbedded within the Triassic-aged sandstone. See “Understanding Earth’s eroding surface with 10Be”, by Portenga & Bierman, p. 4–10. Photo by Eric Portenga.
