Exempel på hur man kan använda K-PG i en mening

• The Cretaceous–Paleogene boundary, also known as the K-Pg or K-T boundary, or the iridium layer, can be viewed in Raton.
• Divergences and losses of flight within ratite lineage occurred right after the K-Pg extinction event wiped out all non-avian dinosaurs and large vertebrates 66 million years ago.
• Their phylogenetics can be traced back to the Cretaceous Terrestrial Revolution after the Cretaceous-Paleogene (K-Pg) mass extinction, followed by repeated dispersals into the rest of the Old World and the New World during various periods beginning in the Eocene.
• During the fallout of the K-Pg event, the ancestor of the attine ants speciated as the resources it depended on as a generalized hunter-gatherer grew scarce.
• In respect of the site being the 'most representative high latitude K-Pg boundary location and one of the most significant and best exposed globally' the 'Cretaceous-Paleogene Transition at Seymour (Marambio) Island' was included by the International Union of Geological Sciences (IUGS) in its assemblage of 100 'geological heritage sites' around the world in a listing published in October 2022.
• The K-Pg boundary occurs at the base of the lowermost seam of Ardley coal zone, based on dinosaurian and microfloral evidence, as well as the presence of the terminal Cretaceous iridium anomaly.
• One of these otolith taxa, the mud-dwelling Pythonichthys arkansasensis, appears to have thrived in the aftermath of the K-Pg extinction, based on its abundance.
• Of the few genera of ammonites which are thought to have survived the K-Pg extinction event into the Danian period (65-61 Myr) of the Paleogene, Hoploscaphites is the most widely and reliably recorded, with finds in Denmark, the Netherlands and the United States, and a possible record in Turkmenistan.
• To account for these Cretaceous fossils, the Hornerstown Formation is generally treated as including the last portion of the Maastrichtian shortly before the Cretaceous-Paleogene boundary, and is thus divided into three sections: the section below the MFL (entirely Maastrichtian), the MFL itself (at the K-Pg boundary), and the section above the MFL (entirely Danian).
