Opis:
Cenomanian mesoeucrocodylians from North America are known primarily from isolated teeth and scutes; any associated remains of this age are noteworthy and represent welcome additions to knowledge. Herein, we describe postcranial elements belonging to a single individual goniopholidid from the Mussentuchit Member of the Cedar Mountain Formation. We argue that this individual represents only the second fossil referable to Dakotasuchus kingi, based on overlapping elements, such as the coracoid, dorsal vertebrae, and scutes, which are strikingly similar to their counterparts in the holotype. The coracoid, in particular, is readily distinguished from those belonging to other closely-related crocodilian taxa; enough so to warrant detailed comparisons in the absence of diagnostic cranial material. The new D. kingi specimen is nearly 20% larger than the holotype, with body length and mass estimates comparable to modern American alligators (Alligator mississippiensis), making it one of the largest aquatic predators in the Mussentuchit ecosystem.

Opis:
Two roadside localities on the northern fringes of Moab, Grand County, Utah yield previously un-described Upper Triassic vertebrate tracks from the Chinle Group (Rock Point Formation). The first locality, designated the high way 191 site, yields dozens of small theropod dinosaur tracks (Grallator) preserved on a single, fallen slab. The tracks form a monospecific assemblage preserved as natural casts. The assemblage is representative of what has been referred to as Rhaetic assemblage II which is dominated by small Grallator tracks. In situ Grallator tracks are also described from a nearby locality, referred to as the Matrimony Spring site, where they are found in association with the ichnogenus Brachychirotherium. Many other sites with similar, often more-diverse, Late Triassic ichnofaunas are known from the region.

Opis:
The newly discovered White Mesa tracksite in the Burro Canyon Formation represents a snapshot of a diverse, Lower Cretaceous dinosaur fauna from south-eastern Utah. The tracks were found at a construction site where the sandstone had been bulldozed and broken up. All tracks were found as deep, well-preserved natural casts on the underside of the sandstone slabs. Individual theropod tracks are 19–57 cm in length; one peculiar track shows evidence of a possible pathological swelling in the middle of digit III and an apparently didactyl track is tentatively assigned to a dromaeosaurid. Individual sauropod tracks are found with pes lengths of 36–72 cm, and interestingly, three distinct shapes of manus tracks, ranging from wide banana shaped to rounded and hoof-like. Ornithopods are represented with individual tracks 18–37 cm in length; a sin gle track can possibly be attributed to the thyreophoran ichnogenus Deltapodus. Zircon U-Pb dating places the track-bearing layer in the Barremian, contemporary to the lower Yellow Cat Member of the Cedar Mountain Formation, which has a similar faunal composition based on both tracks and body fossils. This new track-fauna demonstrates the existence of a diverse dinosaurian assemblage in the lower part of the Burro Canyon Formation, which hitherto is not known to yield skeletalre mains.

Opis:
Stan Utah leży na środkowym zachodzie USA. Zajmuje on 219 887 km2 powierzchni, którą zamieszkuje 2,800 tys. mieszkańców (2009 r.). Gęstość zaludnienia jest stosunkowo niewielka i wynosi ponad 12os/km2. Wpływ na tę sytuację mają przede wszystkim stosunkowo niekorzystne warunki naturalne z których najważniejszy wpływ ma ukształtowanie terenu i warunki klimatyczne. Różnorodność krajobrazu będąca efektem ogromnego zróżnicowania form rzeźby, wpłynęła na fakt iż na terenie Utah powstało 5 parków narodowych (Zion, Bryce, Capitol Reef, Arches i Canyonlands), utworzono pomniki narodowe oraz obszary o niższej randze ochrony. Każdy z tych obszarów przyciąga rzesze turystów z USA i z całego świata, gdyż znajdują się tu niepowtarzalne formy krajobrazu, jak np. w Arches NP znajduje się ponad 1700 naturalnych łuków skalnych. Obszary te mają ogromne znaczenie dla rozwoju turystyki (geoturystyki) w USA, a tym samym dla gospodarki. Rocznie parki narodowe w Utah odwiedza ok. 6 mln osób.
The state of Utah is located in west-central United States. The area of 219 887 km2 is populated by 2.8 million people (in 2009). Population density is relatively low: 12 persons per square km. The main reasons for low population density are unfavourable natural conditions. The most important are topography and climate. Utah’s landscape diversity is a consequence of a variety of terrain types. For that reason, there are 5 national parks (Zion, Bryce, Capitol Reef, Arches and Canyonlands), national monuments, and other lower rank protected areas established in Utah. Each of these places, characterized by unique types of landscape brings millions of tourists per year from USA and all over the World. For example, Arches National Park has more than 1700 natural arches. All these protected areas are very important in development of tourism industry (geotourism), as well as in economy of USA. Utah’s national parks draw more than 6 million visitors annually.

Opis:
The Lower Jurassic Whitmore Point Member of the Moenave Formation in Arizona-Utah, USA, comprises fish- and coprolite-bearing shales, siltstones, sandstones, and minor limestones. These facies were deposited in ephemeral and perennial lakes subject to episodic desiccation and incursions of coarse clastics during floods. Meromictic conditions developed during perennial episodes, probably due to salinity stratification, which enhanced preservation of organic matter in gray to black shales. These lakes formed on the floodout of a north-northwest oriented (relative to modern geography) system of mainly ephemeral streams on a broad and open floodplain. The Whitmore Point Member both overlies and interfingers laterally with alluvial red-bed facies of the Dinosaur Canyon Member of the Moenave Formation. The vertical transition from alluvial to lacustrine sedimentation recorded by the Dinosaur Canyon and Whitmore Point members of the Moenave Formation most probably resulted from a eustatically-controlled rise in base level during the Early Jurassic (Hettangian). The Dinosaur Canyon Member also interfingers laterally with eolian dune deposits of the Wingate Sandstone, which was deposited by winds that reworked coastal plain sediments to the north of the study area. Thus, on this part of the Colorado Plateau, fluvial, lacustrine and eolian sedimentary facies were deposited contemporaneously in laterally adjacent paleoenvironments.
