In sharp contrast, the period between 14,300 and 11,100 years ago, which includes the Younger Dryas interval, was an interval of reduced sea level rise at about 6.0–9.9 mm/yr. Meltwater pulse 1C was centered at 8,000 years ago and produced a rise of 6.5 m in less than 140 years, such that sea levels 5000 years ago were around 3m lower than ...
Sea levels reached their highest level in all of geologic history during the Cretaceous, although they declined before the period ended. [77] Scleractinian corals were more diverse during the Cretaceous than they are today. Back then coral reefs formed along the Gulf coast. [78] Rudist bivalves also constructed reefs in the Gulf coast region. [79]
The Western Interior Seaway (also called the Cretaceous Seaway, the Niobraran Sea, the North American Inland Sea, or the Western Interior Sea) was a large inland sea that split the continent of North America into two landmasses for 34 million years. The ancient sea, which existed from the early Late Cretaceous (100 Ma) to the earliest Paleocene ...
Historic cities and towns along the Southeastern U.S. coast have survived wars, hurricanes, disease outbreaks and other calamities, but now that sea levels are creeping up with no sign of stopping ...
The Zanclean flood or Zanclean deluge is theorized to have refilled the Mediterranean Sea 5.33 million years ago. [1] This flooding ended the Messinian salinity crisis and reconnected the Mediterranean Sea to the Atlantic Ocean, although it is possible that even before the flood there were partial connections to the Atlantic Ocean.

Comparison of two sea level reconstructions during the last 500 million years. The scale of change during the last glacial/interglacial transition is indicated with a black bar. [1] Paleohydrology, or palaeohydrology, is the scientific study of the movement, distribution, and quality of water on Earth during previous periods of its history. The ...
Postglacial Sea level Rise Curve and Meltwater Pulses (MWP) Meltwater pulse 1B (MWP1b) is the name used by Quaternary geologists, paleoclimatologists, and oceanographers for a period of either rapid or just accelerated post-glacial sea level rise that some hypothesize to have occurred between 11,500 and 11,200 years ago at the beginning of the Holocene and after the end of the Younger Dryas.

Researchers have identified five other major extinction events in Earth's history, with estimated losses below: [11] End Ordovician: 440 million years ago, 86% of all species lost, including graptolites; Late Devonian: 375 million years ago, 75% of species lost, including most trilobites
