April Flowers for redOrbit.com - Your Universe Online Climatologists use deep-drilled ice core samples in order to understand the climate changes our planet has endured during and between the Ice Ages. A team of scientists has recently developed a new technique, described in the Proceedings of the National Academy of Sciences, to confirm the age of a 120,000-year-old sample of Antarctic Ice. Scientists will be able to use the new dating technique to identify ice that is much older,...

Understanding How Climatic Relationships Led To Major Ice Age Cycles
2014-04-17 07:45:44

April Flowers for redOrbit.com - Your Universe Online A new study has developed crucial new information about how the ice ages came about based on newly discovered relationships between deep-sea temperature and ice-volume changes. The international team of researchers, led by the University of Southampton, developed a new method for determining sea-level and deep-see temperature variability over the past 5.3 million years. Their findings were published in a recent issue of Nature. The...

Researchers Find Rare Fossilized Embryos More Than 500 Million Years Old
2014-04-11 13:06:23

Jeff Sossamon, University of Missouri The Cambrian Period is a time when most phyla of marine invertebrates first appeared in the fossil record. Also dubbed the “Cambrian explosion,” fossilized records from this time provide glimpses into evolutionary biology when the world’s ecosystems rapidly changed and diversified. Most fossils show the organisms’ skeletal structure, which may or may not give researchers accurate pictures of these prehistoric organisms. Now, researchers at the...

Brown University Using sediments from a remote lake, researchers from Brown University have assembled a 60,000-year record of rainfall in central Indonesia. The analysis reveals important new details about the climate history of a region that wields a substantial influence on the global climate as a whole. The Indonesian archipelago sits in the Indo-Pacific Warm Pool, an expanse of ocean that supplies a sizable fraction of the water vapor in Earth's atmosphere and plays a role in...

Amphibians, Dinosaurs Were The New Large Predators After The Mass Extinction
2014-03-20 12:37:13

University of Zurich 252 million years ago the largest extinction event occurred at the end of the Permian age. It wiped out almost 90 percent of all life in water. So far researchers had assumed that the ecosystems gradually recovered from this catastrophe over a long stretch of eight to nine million years and that large predators at the uppermost end of the food chain were the last to reappear. A Swiss-American team of palaeontologists headed by Torsten Scheyer and Carlo Romano from the...

life reconstruction of the new oviraptorosaurian dinosaur species Anzu wyliei
2014-03-20 04:30:15

Lee Rannals for redOrbit.com - Your Universe Online Researchers writing in the journal PLOS ONE have discovered a new bird-like dinosaur named Anzu wyliei. The fossil skeletons of Anzu were discovered in North and South Dakota underneath 66-million-year-old rocks. Anzu gives scientists the chance to study the anatomy and evolutionary relationships of Caenagnathidae, which is a group of theropod dinosaurs. “Anzu is far and away the most complete caenagnathid that has ever been...

Brett Smith for redOrbit.com - Your Universe Online The reexamination of a dinosaur skull found in Alaska has revealed that it may have belonged to a “smaller cousin” of Tyrannosaurs Rex – not a completely distinct species as originally believed. According to a report on the examination published on Wednesday in the journal PLoS ONE, the skull belonged to a lineage of theropods, or “beast feet,” dinosaurs that includes T. Rex. With most T. Rex fossils coming from temperate...

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
2012-11-18 19:10:56

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...
