Abstract A dinosaur track assemblage from a remote, high altitude (∼4,500–5,000 m) site on the is the first to be reported from this area. The location, here named the Yangguang tracksite, represents the Lower Cretaceous part of the Kezilesu Group consisting of feldspathic sandstones and dated as Hauterivian–Barremian on the basis of the palynoflora. As the site is a dangerous working environment, with a steep (65°) track-bearing surface and constant freeze-thaw-induced rock fall, a photographic...

It has long been known that Lower Jurassic theropod track assemblages are dominated by theropod tracks including Eubrontes and Grallator, known from North America since the mid 19th century. It was...

: Here we describe an extremely large and relatively complete (roughly 65%) skeleton of Tyrannosaurus rex (RSM P2523.8). Multiple measurements (including those of the skull, hip, and limbs) show that RSM P2523.8 was a robust individual with an estimated body mass exceeding all other known T. rex specimens and representatives of all other gigantic terrestrial theropods. Histological sampling of the fibula confirms that RSM P2523.8 is skeletally mature. The prevalence of incompletely coossified el...

Abstract Slabs with tetrapod tracks from the Madigou Village quarry in the Tuchengzi Formation have famously been used as building stones at the imperial summer resort locality, also referred to in the ichnological literature as the “Chengde Summer Palace.” The Jurassic-Cretaceous boundary Tuchengzi Formation has elsewhere in the region yielded differently composed ichnofaunas with non-avian and avian theropod and sauropod tracks. The Madigou assemblage is remarkable because it shows the co-occu...

The Qiaomaigoumen dinosaur tracksite was previously described briefly in 1995 and 2006 based on examination of a single surface (∼200 m) with five trackways representing two quadrupedal ornithopods (Caririchnium isp.) and three bipedal theropods. While confirming this general description, this study also revealed that two additional sites (Sangyuan I and II) had been found, and that tracks from all three sites had been collected for local institutions. This created the opportunity to describe th...

Abstract An Early Cretaceous dinosaur ichnofauna is reported from the Taoqihe Formation (Aptian–Albian) in Heilongjiang Province, China. The assemblage, which comprises >70 tracks in 5 trackways, includes parallel sauropod trackways, a toe-trace dominated tridactyl ornithopod trackway and elongate tridactyl theropod tracks, the latter tentatively be attributed to swimming activity. The combination of possible swim and walking trackways suggest that they were formed at different times and in diff...
