...BETHANIA C.T. SIVIERO; ELIZABETH REGA; WILLIAM K. HAYES; ALLEN M. COOPER; LEONARD R. BRAND; ART V. CHADWICK ABSTRACT This study presents evidence of pre-mortem traumatic injury and its sequalae on multiple Edmontosaurus annectens skeletal elements recovered from a largely monodominant Cretaceous...

...Table 2.— Survival of skeletal elements of Edmontosaurus annectens , predicted from MNI versus actual. For brevity, only select major elements are shown, following Gangloff and Fiorillo (2010) . Abbreviations: MNI = Minimum Number of Individuals (see Badgley 1986 ); NA = Not Applicable . ...

... isolated complete and nearly complete skeletons and skulls. It and other closely related hadrosaurines are among the most common dinosaurs in the late Campanian and Maastrichtian of Laramidia ( Weishampel and Horner 1990 ; Horner et al. 2004 ; Weishampel et al. 2004 ).

... regalis based on the overall thick (dorsoventrally tall) appearance of the orbital margin that may be more typical of E. regalis (CMN 2289) than Edmontosaurus annectens (SM R4050). However, variation in the thickness of the frontal has not been examined in detail, and we recognise that any...

... , Arrhinoceratops , Eotriceratops , and Pachyrhinosaurus . A different species of Edmontosaurus ( Edmontosaurus annectens ) has been recovered from the overlying Scollard Formation, which also produces the remains of Triceratops in southern Alberta. The size, proportions, and gentle anterolateral curvature...

... 2002.4.1 held at the Burpee Museum, Rockford, Illinois, United States). The feet of this specimen are smaller than the track but are of comparable morphology. Other animals with tridactyl feet of appropriate size recovered in the immediate vicinity include both Edmontosaurus annectens and Anatotitan...

Dinosaurs from the Denver Basin include Triceratops , Torosaurus , Edmontosaurus , Thescelosaurus , Edmontonia , Pachycephalosaurus , Tyrannosaurus , a dromaeosaurid, and Ornithomimus . All of these taxa are also known from the Lance, Hell Creek, and Scollard...

Due to the limited number of overlapping bones among these taxa, several size proxies were used to maximize...
