Cretaceous research (Print), 2019
Sedimentological studies of the Upper Cretaceous–lower Eocene limestones in the western part of the Ionian basin (Araxos area) indicate that these deposits are composed of calciturbidites interbedded with breccia-microbreccia.

Late cretaceous and paroxysmal cretaceous/tertiary extinctions
Deep Sea Research Part B. Oceanographic Literature Review, 1987The various geological signatures at Cretaceous/ Tertiary time including iridium and other associated elements, microspherules, and shock deformation features are compatible with the suggestion that the transition is marked by a period of intense volcanism.

Science, 1978
Exceptionally well preserved larval bivalve shells have been isolated from Late Cretaceous (Maestrichtian) sediments. Specimens were readily identified to familial level on the basis of gross morphology and hinge structures. Reconstruction of fossil larval ontogeny, linked with the distribution of adult stages, will provide an important interpretative ...

The Cretaceous-Tertiary Transition
Science, 1983The fossil sequences from cores across the Cretaceous-Tertiary boundary show a range of transition times and transition time intervals depending on the fossil indicators and the location of the site. These variations, together with the pattern of iridium distribution with depth at some sites, differences in total amounts of iridium, variations in noble

AbstractCretaceous rocks extend through the mid-continent from northern Yukon Territory and District of Mackenzie southward along Mackenzie and Rocky Mountains and eastward across the Plains of Alberta, Saskatchewan, and Manitoba to the Canadian Shield. They underlie Mackenzie Delta and Plains in the District of Mackenzie. Exposures of Cretaceous rocks

Abstract Pangaea experienced further disintegration during the Cretaceous. The main body of Laurasia approached its modem location but the Eurasian part deviated remarkably south-westward, forming an angle of several tens of degrees with modem latitudes.
