A new study details the only fossilized specimen of a species previously unknown to science—an “obscure” stalked filter feeder.
To many in southern Utah it’s known as the “Glitter Mine” but to one Veyo business owner, Russ Feller, it’s more than that, it’s his livelihood.

Above the Virgin River valley, evening sun strikes outcrops of the Jurassic-age Navajo Sandstone. Weathering patterns and alternating bands of chemically oxidized (red) and reduced (white) mineral cements combine to produce interesting patterns of texture and color.

Dugway Proving Ground is an expansive military installation that covers parts of the southern Great Salt Lake Desert and Government Creek Basin, and the southern Cedar Mountains, Wildcat Mountain, Granite Peak, and northern Dugway Range. The ranges contain Paleozoic marine sedimentary rocks about 28,000 feet (8540 m) thick, excepting Granite Peak- a Late Jurassic granitic intrusion. The southern Cedar Mountains volcanic field contains Eocene intermediate to silicic rocks, while the rhyolitic Sapphire Mountain lava flow is Miocene. Paleozoic rock packages are distributed among at least three thrusts sheets of the Sevier fold-thrust belt (Cretaceous to Eocene). Regional extension since about 20 million years ago has broken the area into basins and ranges along high-angle normal faults. Quaternary surficial deposits originated from the Bonneville lake cycle, and alluvial, eolian, and mixed environments. A unique feature is the Old River Bed and associated delta complex at its northern terminus, related to surface- water overflow and goundwater discharge from the Sevier basin to the Great Salt Lake basin between about 15,000 and 10,000 years ago. The delta was occupied by prehistoric humans.
A historic dinosaur site is getting a second look – and possibly a second hypothesis of how the bones got there.
BRYCE, Utah – Bryce Canyon National Park will hold the 10th Annual Geology Festival July 15-16, 2016. This year’s theme is “Exploring the Eocene Epoch: Dawn of Modern Mammals”, which is the time when the rocks of Bryce Canyon were forming. Join guest speaker, Dr. L. Greer Price of the New Mexico Geological Survey as he presents “Earth Sciences for the 21st Century: Where we’ve been and where we’re going”.
