• They range in the fossil record from 84 to 71 million years ago, from the late Santonian, through the Campanian and early Maastrichtian ages.
• A chronostratigraphic stage of sedimentary rock (in stratigraphy) has been named after the former name for inhabitants, the Santones, the Santonian (approximately 84 Ma ago, after the Coniacian Age and before the Campanian Age in the Cretaceous Period).
• Catherine's Hill, the Lewes Nodular Chalk at Twyford Down, the Seaford Chalk under the village, to the Santonian or Campanian Newhaven Chalk to the south.
• The top of the Coniacian (the base of the Santonian Stage) is defined by the appearance of the inoceramid bivalve Cladoceramus undulatoplicatus.
• The GSSP (official reference profile) for the base of the Santonian Stage is located near Olazagutia, Spain; it was ratified by the Subcommission on Cretaceous Stratigraphy in 2012.
• These winds were also the cause of a significant aridification of the climate in this region during the Santonian and early Campanian, causing a change in the flora of angiosperms, with a rarefaction of broad-leaved forms and a proliferation of small and narrow-leaved species of the family Ulmaceae.
• Bonitasaura is a genus of titanosaurian dinosaur hailing from uppermost layers of the Late Cretaceous (Santonian) Bajo de la Carpa Formation, Neuquén Group of the eastern Neuquén Basin, located in Río Negro Province, Northwestern Patagonia, Argentina.
• However, examination of the magnetostratigraphy of the formation indicates that the entire Bayan Shireh lies within the Cretaceous Long Normal, which lasted only until the end of the Santonian stage, giving a possible Cenomanian through Late Santonian age, between 98 and 83 million years ago.
• Hungarosaurus tormai (meaning 'Hungarian lizard' from the Latin Hungaria 'Hungary' and Greek σαυρος / 'sauros' 'lizard'), is a herbivorous nodosaurid ankylosaur from the Upper Cretaceous (Santonian) Csehbánya Formation of the Bakony Mountains of western Hungary.
• Though represented by relatively small forms throughout the Turonian and Santonian, such as Clidastes, the lineage diversified during the Campanian and had by the Maastrichtian grown into the most diverse and species-rich mosasaur subfamily.
• Tylosaurines first appeared in the Coniacian and gave rise to some of the largest mosasaurs within the genera Tylosaurus and Hainosaurus which came to dominate as apex predators in marine ecosystems throughout the Santonian and Campanian, but appear to have been largely replaced by large mosasaurines, such as Mosasaurus, by the end of the Maastrichtian.
• Eonatator is known from the Smoky Hill Chalk Member of the Niobrara Chalk Formation (Late Coniacian to Early Campanian) of Kansas, from the Eutaw Formation (Santonian) and Mooreville Chalk Formation (Selma Group; Santonian-Lower Campanian) of Alabama (United States), from the Kristianstad Basin of southern Sweden (late early Campanian), and the unit Nivel de Lutitas y Arenas (Campanian) of the Olini Group in La Mesa, Colombia.
• It is the younger of two formations belonging to the Río Neuquén Subgroup within the Neuquén Group of the Neuquén Basin, with the oldest rocks dating from the late Coniacian and its youngest maybe from the very start of the Santonian.
• Definitive leptoceratopsids have so far been found exclusively in the Late Cretaceous period (late Santonian - late Maastrichtian stages) of Asia and Western North America; A possible leptoceratopsid ulna, named Serendipaceratops, has been found in Victoria, Australia.
• Most fossil species are known from the Late Cretaceous (Santonian) Taimyr amber of Russia and Late Cretaceous (Campanian) Canadian amber, but one species, Baeomorpha liorum is known from the mid Cretaceous (late Albian-earliest Cenomanian) Burmese amber.
• Allocrioceras is an ammonoid cephalopod from the Turonian to Santonian stages of the Late Cretaceous, included in the turrilitoid family Anisoceratidae.
• Taymyr amber (also spelled Taimyr) - found in Taymyr Peninsula (northern Russia), Cretaceous (Cenomanian and Santonian) aged amber.
• †Glaesoconis Meinander 1975 Burmese amber, Myanmar, Cenomanian, New Jersey amber, Turonian Taimyr amber, Late Cretaceous (Santonian).
• Biostratigraphy of sea turtles and possible bite marks on a Toxochelys (Testudine, Chelonioidea) from the Niobrara Formation (Late Santonian), Logan County, Kansas and paleoecological implications for predator–prey relationships among large marine vertebrates.
• The first "protosuchian" (Archosauria: Crocodyliformes) from the Cretaceous (Santonian) of Gondwana.
