What did the Colorado Plateau look like 250 million years ago? That’s a question geologists hope to shed some light on via an ambitious project that is pulling rock cores up from as much as 1.5 kilometers down into the plateau’s belly. The Colorado Plateau is an expansive region, taking in parts of Colorado, Utah, Arizona, and New Mexico. Within this geologic province are some of our most iconic national parks: Arches and Canyonlands, Bryce Canyon and Zion, the Grand Canyon and Petrified Forest to name the most recognizeable. What makes them so stunning is the geology from which they rise.

A 656-page book chronicling the paleontological discoveries and success evidenced so far at Utah’s Grand Staircase-Escalante National Monument has been published, even as new discoveries continue to unfold on a near daily basis.
“I am here to emphasize that we are just getting started at the Grand Staircase,” said Alan Titus, the monument’s paleontologist. “We have a great big sandbox to play in.”

Following the 1996 establishment of the Grand Staircase–Escalante National Monument (GSENM), paleontological research in this largely unstudied region of the nation accelerated at a remarkable pace, thanks to an infusion of research dollars from the federal government. Much of this research centered on the Upper Cretaceous of the Kaiparowits Plateau, which is at the center of the most continuous belt of terrestrial Cretaceous rocks anywhere in North America. The Utah Geological Survey was in the thick of it with early general survey projects and the later, more focused, Wahweap Project in the southern Kaiparowits Plateau from 2001–2005, which resulted in the discovery of Diabloceratops eatoni. Additionally, significant funded projects were undertaken by the Museum of Northern Arizona and the Natural History Museum of Utah (NHMU).

The results of this burst of scientific exploration has now been summarized in the massive  volume “At the Top of the Grand Staircase: The Late Cretaceous of Southern Utah,” edited by the Alan L. Titus (GSENM) and Mark Loewen (NHMU), published just this past month by Indiana University Press. The 634-page book includes 28 chapters, starting with papers on the geology and sedimentology of the regions, followed by papers on the fossil plants, invertebrates, fish, amphibians, turtles, lizards, crocodilians, marine reptiles, and chapters on each major group of dinosaurs. The UGS’s Jim Kirkland, Don DeBlieux, and Martha Hayden just received their complimentary copies of the volume for their contributions and will be spending the rest of the year looking over this magnificent contribution to our knowledge of Utah’s geological and paleontological record.

To those who have taken the time to explore Utah’s rivers, standing on the patio of the John Wesley Powell River History Museum and staring at the muddy waters of the Green River below brings back many feelings and emotions. Desolation Canyon, the Gates of Lodore, Split Mountain, Echo Park and the undammed Yampa lie upstream, filled with rapids, incredible scenery and compelling history.

On Maine’s rugged coast, just north of the tourist town of Boothbay, an underground seismometer is listening for earthquakes. Engineers activated it on 26 September, completing the US$90-million Transportable Array, an ambitious effort to blanket the contiguous United States with a moveable grid of seismic monitors (see ‘On the march’).

Weighing in at more than 2 tons and two dozen feet long, a new species of dinosaur related to Tyrannosaurus rex was fierce enough to be dubbed “King of Gore.” The discovery of “Lythronax argestes” at the Grand Staircase-Escalante National Monument in Utah was announced Wednesday at the Natural History Museum of Utah and coincides with the publication of a study in PLoS ONE, an open access scientific journal.

A remarkable new species of tyrannosaur has been unearthed in Grand Staircase-Escalante National Monument (GSENM), southern Utah. The huge carnivore inhabited Laramidia, a landmass formed on the western coast of a shallow sea that flooded the central region of North America, isolating western and eastern portions of the continent for millions of years during the Late Cretaceous Period, between 95-70 million years ago. The newly discovered dinosaur, belonging to the same evolutionary branch as the famous Tyrannosaurus rex, was announced today in the open-access scientific journal PLOS ONE and unveiled on exhibit in the Past Worlds Gallery at the Natural History Museum of Utah at the Rio Tinto Center in Salt Lake City, Utah.

Utah State University’s Department of Geology announces the opening of a new museum on the school’s Logan campus, along with the return of the department’s popular ‘Rock and Fossil Day,’ Saturday, Nov. 9, from 10 a.m.-2 p.m.

All ages are invited to the free event, which features a variety of hands-on educational activities along with admission to museum exhibits.

For something that is supposed to keep track of 4 billion years of history, the geologic time scale is quite a fuzzy and slippery yardstick. After two centuries of careful research and argumentation, the world’s geologists have only recently adopted a system to literally nail down the different time periods taught in geology school. Last week that project took another slow step forward as a “golden spike” was officially driven into a precise spot on the ground near Pueblo, Colorado, a benchmark for the beginning of the Turonian Age.

Cambrian Fossils in Utah’s West Desert, Millard County

Utah is recognized for having the longest and most diverse dinosaur record in the nation. Yet, the Cambrian rocks in Utah’s West Desert contain one of our nation’s best records of the early evolution of life on Earth. View a slideshow of rocks and fossils from the West Desert here. During the Cambrian Period, North America straddled the Equator and the continent was oriented nearly 90 degrees clockwise of its present position. The Cambrian coastline extended north-south across Utah shifting southward (our east) with rising sea level. This resulted in a nearly complete sequence of Cambrian rocks preserved in Utah’s West Desert on what was the northern coastline of early North America. When Tertiary extension forces formed the Basin and Range Geological Province throughout the last 20 million years, these Cambrian rocks became well-exposed across western and central Utah, revealing the extraordinary fossil record within. Nowhere is this geology better exposed than in Millard County, Utah. Refer to Hintze and Davis (2003) (17 MB PDF) for a detailed discussion of the county’s geology. The Cambrian is best known for the “Cambrian Explosion” (or “Cambrian Radiation”) , when a great diversity of multicellular animals first appears. The first scientific report on these fossils was a description of Elrathia kingii in 1860, probably the world’s most well-known trilobite species.
