Life Beneath the Surfaces of Active Jurassic Dunes: Burrows from the Entrada Sandstone of South-Central Utah (2008)

David B. Loope

Within the Middle Jurassic Entrada Sandstone of south-central Utah, cylindrical burrows, 15–95 mm diameter, are abundant in large-scale, eolian cross-strata. Burrows are oriented at a high angle to...

Lowell Dingus, David B. Loope, Demberlyin Dashzeveg, Chuluun Minjin, Michael J. Novacek, ...

The lithostratigrahy and sedimentology of the fossiliferous Upper Cretaceous strata exposed in the Gobi Desert of Mongolia at Ukhaa Tolgod are described and mapped on aerial photos. Topographic...

Dry-Season Tracks in Dinosaur-Triggered Grainflows (2006)

DAVID B. LOOPE

Thousands of animal tracks are preserved in wind-blown cross-strata of the Lower Jurassic Navajo Sandstone at Coyote Buttes on the Arizona-Utah border, USA. Tracks deform thin grainflows that were...

New Stratigraphic Subdivision, Depositional Environment, and Age Estimate for the Upper Cretaceous Djadokhta Formation, Southern Ulan Nur Basin, Mongolia (2005)

DEMBERELYIN DASHZEVEG, LOWELL DINGUS, DAVID B. LOOPE, TOGTOKH DULAM, MARK R. SWEENEY

Studies of key and newly discovered sections of the Upper Cretaceous Djadokhta Formation along the southern margin of the Ulan Nur Basin allow a new subdivision based on lithology. The formation and...

ABNORMAL, MULTILAYERED TITANOSAUR (DINOSAURIA: SAUROPODA) EGGS FROM IN SITU CLUTCHES AT THE AUCA MAHUEVO LOCALITY, NEUQUÉN PROVINCE, ARGENTINA (2004)

FRANKIE D. JACKSON, ALBERTO GARRIDO, JAMES G. SCHMITT, LUIS M. CHIAPPE, LOWELL DINGUS, DAVID B. LOOPE
