Map of Grand Staircase-Escalante National Monument (GSENM), southern Utah (A), and generalized stratigraphic section of the upper Campanian Kaiprowits Formation (B). The approximate stratigraphic position of Akainacephalus johnsoni is located near the base of the middle unit within the Kaiparowits Formation. The map highlights the GSENM boundary (dashed line), showing the geological distribution and outcrops of the Cretaceous Kaiparowits, Wahweap, and Straight Cliffs formations. The red star indicates the Horse Mountain area, from which Akainacephalus johnsoni was recorded. Map and stratigraphic column modified from Roberts (2005). Radioisotopic dates used from Roberts, Deino & Chan (2005) and Roberts et al. (2013), respectively.

Dryolestidan mammal Crusafontia amoae sp. nov., MPZ CC2−1 M4 or M5, holotype, from the site of Cuesta Corrales 2, Colladico Blanco level, El Castellar Formation, Galve, Teruel, Spain in, occlusal (A), mesial (B), labial (C), distal (D), and lingual (E) views. The schematic drawing of C. amoae, in the box in the lower left−hand corner shows the main anatomical elements of the occlusal surface of a dryolestidan.
A trackway of the trace fossil Bifurculapes laqueatus (positive hyporelief, i.e. casts on the bottom surface of the bed) from the Early Jurassic East Berlin Formation (Hartford Basin) of Holyoke, Massachusetts (not the same specimen as this one). Scale is in cm.
Geological context of the Lower Cretaceous deposits of southeast England, focussing on the Purbeck Group and Wealden Supergroup. (A) Schematic geology of the Lower Cretaceous deposits of the Weald Sub-basin (southeast England), highlighting published spinosaurid finds (Charig & Milner, 1997; Salisbury & Naish, 2011; Turmine-Juhel et al., 2019). Based on Austen & Batten (2018: Fig. 2). Note that various additional spinosaurid teeth are known from the region but remain undescribed in detail (Fowler, 2007). (B) Simplified stratigraphic column of the Weald Group in southeast England, based on Batten & Austen (2011: Fig. 3.2). Note that the Grinstead Clay Formation, which subdivides the Tunbridge Wells Sands Formation in Batten & Austen (2011) and from which the “Suchosaurus cultridens” type specimen was discovered (Salisbury & Naish, 2011), is downgraded to a member of the latter formation in other works (Hopson, Wilkinson & Woods, 2008) and has not been included in this column.

1865.. WHITAKEE BXrCKlNGHAM CHALK, 399 I cannot give the thickness with accuraC3\ I will now give a short account of each, beginning with the lowest. (g). Chalk-marl. — A rather brownish-white, slightly sandy, clayey chalk, fissile, with stony layers here and there, and often with fossils (notably fish-scales). This is per- haps 80 feet thick, and mostly causes a rise of the ground above the sloping plain of the Upper Green- sand. (/). Totfernlioe Stone.- At the top of the Chalk- marl in this district there are generally two layers of rathersandy limestone, separated by a little marl, and which are more dis- tinct further north-east- ward (in Bedfordshire), where they are each about 3 feet thick. One bed is always here present, but I did not always see the two. This stone mostly yields fossils, amongst which Ammonites vai'ians and an Inoceramus are abundant, and small, hard,dark-brown nodules, most likely coprolitic : it is harder and darker than common chalk, and con- tains many small dark grains ; and was once largely quarried, for build- ing, at Totternhoe, where there are plentiful traces of the workings. Most of the old churches of the neighbourhood were built in great part of this pe- rishable stone, but I be- lieve that its use has been long discontinued. Details of the occur- rence of this bed will be given in the ' Gcolo- 2 E 2
Sundon South Chalk Pit. This cement plant quarry ceased operation in December 1976. The photograph was taken earlier that year. The pit is about the same now, although full of trash and less easily interpreted due to weathering. The blocky material in the middle of the upper quarry face is Totternhoe Stone, the lowest member of the "Grey Chalk". Below it is the "Chalk Marl". The calcium carbonate content of the rock varied steadily from 60% at the bottom to 85% at the top. A cement rawmix of 78.5% carbonate was made by combining the layers. The chalk was dug with three excavators. A dragline on the hill top scraped the soft chalk from above the Totternhoe Stone and dropped it onto the lower bench, forming the scree-like piles visible here. A face shovel on the lower bench undermined and prised out the hard Totternhoe Stone, and loaded it and the soft chalk into rail trucks (see 645414). A second dragline, also on the lower bench, scraped marl up from below, and added it to the rail trucks. The chemistry of the mixture was controlled by specifying the number of buckets of marl to be added to each train-load.

Geographic and stratigraphic relationships of the holotype EMK 0012 and the Loki Quarry in northern Montana. (A) Regional relationships between the cross-border paleontological sites in the Oldman and Judith River formations along the Milk River and in Kennedy Coulee in Alberta and Montana. (B) Generalized stratigraphic section in the Kennedy Coulee area modified after Goodwin & Deino (1989) and Rogers, Eberth & Ramezani (2023) with the relationships between the Foremost and Oldman formations in Canada and the Judith River Formation in Montana. Relative placements of important taxa in this area are indicated. Position of 40Ar/39Ar dates originally obtained by Goodwin & Deino (1989) are shown in relation to the new U–Pb CA-ID-TIMS date for KC061517-1 by Ramezani et al. (2022). Bentonite ash beds are only 5 to 7 cm thick so they are exaggerated for clarity. Scale bars delineated in map view are indicated kilometers and in meters stratigraphically.

Text Appearing Before Image: This season of 1921 George Sternberg became the first dinosaur col- lector on the Red Deer River to have his work recorded in motion pictures. This happened by a curious error. The Dominion Motion Picture Bureau, predecessor of the National Film Board of Canada, had decided to make a short motion picture based on the work being done by the Geological Survey of Canada in the collecting and displaying of Canadian dinosaurs. The camera party sent to Alberta was naturally supposed to visit the Geological Survey party under Charles M. Sternberg, but local directions sent them to the camp of George Sternberg. So this excellent little film records field work by the University of Alberta party and preparation being done at the National Museum of Canada in Ottawa. That winter George Sternberg continued the preparation of the speci- mens obtained during the two preceding field seasons, but in the spring he resigned to accept a position with the Field Museum of Natural History of Chicago, under Elmer S. Riggs. The summer of 1922 was the last time that the eldest of the Sternberg sons worked on the Red Deer River, his collec- tion going to Chicago. However, he returned to Edmonton for several months in 1935, to complete the preparation of the collection that he brought together in 1920 and 1921. When George Sternberg left the Geological Survey of Canada in 1918, the only one of the four Sternbergs remaining at Ottawa was Charles Mortram Sternberg, the second son of C. H. Sternberg. Actually, Charles had his first independent expedition to the Red Deer badlands in 1917, C. M. Sternberg ami G. E. Lindblad working on the skull of a horned dinosaur (Centrasaurus sp.), Oldman formation, Red Deer River, 1917. N.M.C., No. 39994.

Kaiparowits Formation (Campanian; Upper Cretaceous) at The Blues, near Powell Point (peak to the left) composed of the Claron Formation.
Natural-colour satellite image of part of the Kaiparowits Basin (a central portion of Grand Staircase-Escalante). The branch-like shapes are networks of canyons carved by rivers that dried up millions of years ago. The ridge running roughly north-south through the scene is the Cockscomb, which is surrounded by distinct rock formations deposited at different times in the geologic past. West of the Cockscomb is the Navajo Sandstone, dating from the Triassic. East of the Cockscomb are two formations from the Cretaceous: the light-toned Wahweap and darker Kaiparowits.
