How Do You Spell LATE CRETACEOUS?

Pronunciation: [lˈe͡ɪt kɹɛtˈe͡ɪʃəs] (IPA)

The Late Cretaceous period is a fascinating time in Earth's history, but the spelling of this term can be confusing. The correct pronunciation is [leɪt kriːˈteɪʃəs], with the stress on the second syllable of "cretaceous." The "e" in "late" is pronounced as "ey," and "cretaceous" starts with a "k" sound, not an "s" sound like the word "creation." The Late Cretaceous was the last stage of the Cretaceous period, ending with the extinction of dinosaurs and the rise of mammals.

LATE CRETACEOUS Meaning and Definition

  1. Late Cretaceous is a term used in the field of paleontology and geology to describe a specific period during the Cretaceous period, which was the last and longest segment of the Mesozoic Era. The Late Cretaceous epoch is known for being the final stage of the Age of Dinosaurs, specifically occurring from approximately 100 to 66 million years ago.

    During the Late Cretaceous, the Earth experienced a warm climate, with high sea levels and extensive shallow seas covering large regions. This epoch witnessed the dominance of reptiles, including various types of dinosaurs such as tyrannosaurs, ceratopsians, hadrosaurs, and ankylosaurs. Additionally, marine reptiles like mosasaurs and plesiosaurs thrived in the paleo-oceanic environments. Furthermore, the first flowering plants, or angiosperms, began to diversify and spread across the globe, influencing the evolution of many animal species.

    This era also marked the end of the Cretaceous period and the Mesozoic Era. The Late Cretaceous concluded with a significant event called the Cretaceous-Paleogene (K-Pg) extinction event, during which three-fourths of all plant and animal species, including the dinosaurs, became extinct. This event is believed to have been caused by a combination of factors, including volcanic activity, impact events, and climate change.

    In summary, the Late Cretaceous is an important geological and paleontological period characterized by the prominence of dinosaurs, the emergence of flowering plants, and ultimately, the mass extinction event that ended the reign of the dinosaurs and led to major changes in Earth's ecosystems.

Etymology of LATE CRETACEOUS

The term "late Cretaceous" is derived from the combination of two words: "late" and "Cretaceous".

The word "late" originates from the Old English term "læt" or "læte", which means "slow" or "behind in time". Over time, its meaning has evolved to connote something occurring near the end or after the expected or usual time.

The word "Cretaceous" is derived from the Latin term "Cretaceus", which means "chalky". It refers to the extensive chalk deposits that were formed during this period. The name "Cretaceous" was first used by the French naturalist Alexandre Brongniart in 1822.
