The Cretaceous (along with the Mesozoic) ended with the Cretaceous–Paleogene extinction event, a large mass extinction in which many groups, including non-avian dinosaurs, pterosaurs, and large marine reptiles, died out, widely thought to have been caused by the impact of a large asteroid that formed the Chicxulub crater in the Gulf of Mexico.

Grandfather Cuts Loose the Ponies (Wikipedia) Grandfather Cuts Loose the Ponies (also known as the Wild Horse Monument) is a public art sculpture created by David Govedare in 1989–1990 and situated near Vantage, Washington. It consists of 15 life-size steel horses which appear to be galloping across a ridge above the Columbia River. Presented as a gift for the centenary of Washington’s statehood, the sculpture was conceived as a memorial to the wild horses which once roamed the region. According to the Seattle Times, it is one of the most-seen public artworks in Washington state.

Cretaceous (Wikipedia) The Cretaceous (IPA: /krɪˈteɪʃəs/ krih-TAY-shəs) is a geological period that lasted from about 145 to 66 million years ago (Mya). It is the third and final period of the Mesozoic Era, as well as the longest. At around 79 million years, it is the longest geological period of the entire Phanerozoic. The name is derived from the Latin creta, “chalk”, which is abundant in the latter half of the period. It is usually abbreviated K, for its German translation Kreide.
