Life and Death of a Planetary System – Exoplanet Exploration: Planets Beyond our Solar System | NASA Exoplanet Program

Seven chapters describe an interstellar journey through time and scientific work on how planetary systems form. The online article includes Q and A's, news updates, and video clips. The article is organized by a timeline.

J. W. Powell's Perilous River Expedition: From a remote sensing perspective | @USGS_EROS | #StoryMap

Powell's jouney 150 years ago became one of the great surveys of the west that led to the formation of the U.S. Geological Survey. Powell said, "The exploration was not for adventure, but purely for scientific purposes, geographic and geologic." But, it turned out to be an epic adventure. The expedition team left Green River, Wyoming, on May 24, 1869, and made it past the Grand Canyon to the confluence of the Colorado River and the Vigin River on August 30. This StoryMap includes 13 layers and provides several stories of the adventure along the way.(source)


How Do We Know What #Dinosaurs Looked Like? | @SciFri @BSoash | #educator #paleontology #paleoart #resource

A free educator's resource by Brian Soash and Science Friday. The resource allows students to explore the process behind what paleontologists and paleoartists do within the context of dinosaurs from the Jurassic Morrison formation. Materials include: student notebook, dinosaur ID guide, and Morrison Formation organisms. Images by Rebecca Hunt-Foster (@paleochick).

Geology | Minnesota River Basin Data Center | #MN #glacial #geology #landscape #videos

An "Ask an Expert" page listing 10 short videos of the geology of the Minnesota River Basin by Dr. Carrie Jennings, a glacial geologist for the Minnesota Department of Natural Resources. Topics include: Story of Lake Aggasiz and Glacial River Warren; geology and water quality; some of Earth's oldest rocks; What is a glacial moraine?; and the bend in the Minnesota River Valley. Additional resource links to: 360 panoramic view; flash animations on MN glaciation and River Warren and valley formation; and a pdf on a DNR excerpt on the Geology of the Minnesota River Basin.

Major bonebeds in mudrocks of the Morrison Formation (Upper Jurassic), northern Colorado Plateau of Utah and Colorado | Geology of the Intermountain West

Download PDF field guide by John Foster et. al. The Morrison Formation contains a number of large quarries that have yielded dinosaurs and other vertebrates, and many of these occur in sandstone beds representing ancient river channels. However, a number of very productive sites occur in mudstone beds representing other environments such as ephemeral ponds, and some of these yield both large dinosaurs and microvertebrates; these localities in mudstone beds represent different taphonomic modes of preservation and often preserve vertebrate taxa in different relative abundances from the channel sandstone sites. Among these important and very productive mudstone localities are the Cleveland-Lloyd Quarry, the Mygatt-Moore Quarry, and the microvertebrate sites of the Fruita Paleontological Area, and each of these preserves distinct vertebrate paleofaunas, different from sandstone sites and from each other, suggesting that mudstone localities had a very different mode of sampling the local biotas than did sites in sandstone.
