Sedimentology and Stratigraphy of the Morrison Formation in Dinosaur National Monument

Stratigraphy, Sedimentology, and Sequence Stratigraphy of the Lower Triassic Sinbad Formation, San Rafael Swell, Utah

The Lower Triassic Sinbad Formation (Thaynes Group) in the San Rafael Swell of east-central Utah (11-18 m thick) represents the maximum flooding zone and at least part of the highstand systems tract of a 185+ m thick depositional sequence. The Sinbad Formation conformably overlies siliciclastic tidal flat, fluvial channel and carbonate peritidal deposits of the Black Dragon Formation, a transgr...

First Report on Reptile Tracks from the Moenkopi Formation (lower-?middle Triassic) in Dinosaur National Monument, Utah

The Lower-Middle Triassic Moenkopi and Red Peak formations, which crop out throughout western North America, contain ubiquitous occurrences of tetrapod tracks attributed to reptiles (Peabody, 1948; Klein and Lucas, 2010; Lovelace and Lovelace, 2012). Although reptile skeletal remains from these formations are rare to non-existent, and largely restricted to the Holbrook Member in Arizona (e.g., ...

Distribution and Significance of Mesozoic Vertebrate Trace Fossils in Dinosaur National Monument

Fluvial transport potential of shed and root-bearing dinosaur teeth from the late Jurassic Morrison Formation

Shed dinosaur teeth are commonly collected microvertebrate remains that have been used for interpretations of dinosaur feeding behaviors, paleoecology, and population studies. However, such interpretations may be biased by taphonomic processes such as fluvial sorting influenced by tooth shape: shed teeth, removed from the skull during life, and teeth possessing roots, removed from the skull aft...
