Long, long before the dinosaurs of the Jurassic Period, the Earth went through the Devonian and the Cambrian periods. And before those, the Ediacaran.

The theory that all animal life emerged from the sea has been well covered, but much less is known about the creatures that went back. Whales, dolphins, seals and sea turtles are examples of marine tetrapods--an exceptional group of animals that moved from the sea to the land and back again.

It’s one of those classic “chicken and egg” conundrums. Most earth scientists agree that there is a connection between sudden increases in the number of icebergs, known as iceberg ‘pulses’, and cycles of abrupt climate change during the last glacial period. The occurrence of extremely cold conditions in the North Atlantic was linked to the dispersal of icebergs that have broken away from ice sheets. But experts couldn’t agree on which came first, the bergs or the sudden climatic...

capitanian extinction

Chuck Bednar for redOrbit.com - @BednarChuck New evidence of severe losses in brachiopods in the northern Boreal latitudes around the island of Spitsbergen suggest that the controversial Capitanian extinction event that occurred about 262 million years ago should be classified as a true “mass extinction” event. Previously, the Capitanian extinction event was known only from equatorial settings, and thus its status as a full-fledged global crisis was controversial. However, the...

Kind of like today with Frozen still taking over the universe, there was a time when everything was frozen, even places near the equator.

Chicxulub impact

For the first time, scientists plan to conduct an expedition to collect and analyze core samples from the 125-mile-wide Chicxulub impact site in Mexico, a crater believed to have been caused by the asteroid that wiped out the dinosaurs more than 65 million years ago.

According to a new study in Proceedings of the Royal Society B, these tiny subterranean nightmares didn’t spread across the globe via landbridges or continental drift. They actually rode bits of driftwood across the oceans to inhabit new lands, as improbable as that might sound.

The secrets of how Earth’s continents first formed over 2.5 billion years ago lie in relatively recent geologic events that took place 10 million years ago in what is now Panama and Costa Rica.

Thank goodness it's spring. The record cold temperatures last month was not a result of climate change, according to researchers from ETH Zurich and the California Institute of Technology.

Hula Painted Frog, Discoglossus nigriventer
2014-08-18 15:55:22

The Hula painted frog was considered extinct by the IUCN since 1996. Very little is known about the species because very few specimens have been found. In 1940 two adults and two tadpoles were collected but the smaller one was eaten by the larger one, and the tadpoles were lost. A single Hula painted frog was found in 1955 which was the last record of this specimen. The extinction of this species is said to be the result of the draining of lake Hula and its marshes in the 1950’s. Only...

Paleontology
2014-01-12 00:00:00

Paleontology or Palaeontology is the scientific study of prehistoric life, including the study of fossils to determine the organisms evolution and interactions with each other and their environments. Paleontological observations have been documented as far back as 5th century BC. The science became established in the 18th century as a result of Georges Cuvier’s work on comparative anatomy, and it developed quickly within the 19th century. The term itself comes from Greek palaios, meaning...

Rainforests
2013-04-19 19:33:20

Rainforests are forests that are characterized by high levels of rainfall, with definitions based on a minimum usual annual rainfall of about 68 to 78 inches. The monsoon trough, or otherwise known as the intertropical convergence zone, holds an important role in producing the climatic conditions that are essential for the Earth’s tropical rainforests. About 40 to 75 percent of all biotic species are native to the rainforests. It’s been estimated that there might be many millions of...

Climate Change
2013-04-01 11:05:27

Climate change is a substantial and lasting change in the statistical distribution of weather patterns over periods of time ranging from decades to millions of years. It might be a change in the average weather conditions, or in the distribution of weather around the average conditions. Climate change is a result of factors that include oceanic processes, biotic processes, variations in solar radiation received buy Earth, volcanic eruptions, and plate tectonics, and human induced alterations...

Geologic Clock With Events And Periods

The Neoproterozoic is the third of three subdivisions of the Proterozoic Eon (occurring from 1 billion years ago to 542 million years ago). This terminal era of the Proterozoic is itself divided into three sub-periods called the Tonian, Cryogenian, and Ediacaran Periods. The most severe glaciation known in the geologic record occurred during the Cryogenian Period, when ice sheets reached the equator and formed a possible “Snowball Earth.” And the earliest fossils of multi-cellular life...
