Cretaceous-Paleogene extinction event at the end of the Cretaceous Period marks the end of the Mesozoic Era and the age of the dinosaurs, eradicating about half of all animal species, including mosasaurs, pterosaurs, plesiosaurs, ammonites, belemnites, rudist and inoceramid bivalves, most planktic foraminifers, and all of the dinosaurs excluding the birds; start of the Paleogene Period and the current Cenozoic Era.
Saminga is created, and upon his first visit to Earth, witnesses the extinction of the dinosaurs.
Rapid dominance of conifers and ginkgos in high latitudes, along with mammals becoming the dominant species. First psammobiid bivalves. Earliest rodents. Rapid diversification in ants.
The Plesiadapiformes very likely contain the ancestor species of all primates. One of the last Plesiadapiformes is Carpolestes simpsoni, having grasping digits but not forward-facing eyes.
