...R. W. Barendregt; E. D. Ongley Abstract The initial 2 years (1975–1977) of a 10 year program of slope process measurement in the Onefour Badlands of Alberta, Canada, has encompassed two highly contrasted moisture regimes with measurable differences to process–response mechanisms. The Onefour...

... to the total group of chelonioid sea turtles (stem + crown), whereas Cheloniidae is restricted to those members of crown-group Chelonioidea that are not part of Dermochelyidae. TMP 1993.124.55, hyoplastron, from L1114 (Baby Ceratops Locality), 6.5 km northeast of Onefour, Alberta. Lsd 6, Sec 30, Tp 2, Rg3...

..., Warner, Alberta, T0K 2L0, Canada. These observations suggest a mechanism for the rapid lithification of the Onefour coprolite. Rapid burial would have provided protection from bioturbation ( Allison, 1988 ) and coprophagy, and generated a closed, anoxic environment where anaerobic decomposition...

... sediments arrived in the Dinosaur Provincial Park region at ∼76.5 Ma ( Eberth and Deino 1992 ) and in the Onefour region of southern Alberta at ∼75.Ma ( Eberth et al. 1990 ). The rate of sedimentation in the Dinosaur Park Formation of ∼4 cm/1000 years suggests that the rate of southerly migration...

...Fig. 1. Map of Alberta showing the distribution of the principal bonebed-hosting Upper Cretaceous geologic units (shaded areas) and bonebed producing areas (stars and numbers). Principal stratigraphic units include the Belly River Group (BRGp), Bearpaw Formation (BPFm), Scollard–Horseshoe Canyon...

... site located near Onefour in SE Alberta (Complex MFIV-1 of Eberth 1996 ; Fig. 1 ). Sediments at this site contain a dominantly freshwater fauna, and are believed to have formed <100 km from the palaeoshoreline ( Eberth 1996 ). No articulated vertebrate material was available from this site, so...

...James D. Gardner; Donald M. Henderson; François Therrien The genesis of the RTMP arguably can be traced back to two events in the mid-1950s in southern Alberta ( Currie and Garneau 1984 ; Baird 1988 ; Spalding 1999 , pp. 141–142; Currie 2005 a ; P.J. Currie, pers. comm., email dated 06...

... ; Cullen et al. 2016 ). However, we cannot unambiguously categorize DPF taxa as marine or terrestrial, because some may have been amphibious, whereas others may have inhabited freshwater habitats, such as those represented by the Onefour mud-filled incised valley (OMFIV) sites (Eberth and Brinkman 1997...
