Fossil fuel. The main fossil fuels (from top to bottom): natural gas, oil, and coal. A fossil fuel[a] is a carbon compound - or hydrocarbon -containing material [2] formed naturally in the Earth's crust from the buried remains of prehistoric organisms (animals, plants or planktons), a process that occurs within geological formations.
Red circles - where giants were really discovered. Green ones are still underdeveloped. What unites both theories of oil origin is the low success rate in predicting the locations of giant oil/gas fields: according to the statistics discovering a giant demands drilling 500+ exploration wells.
Free-air gravity anomaly over the Chicxulub structure (coastline and state boundaries shown as black lines) The Chicxulub crater (IPA: [t͡ʃikʃuˈluɓ] ⓘ cheek-shoo-LOOB) is an impact crater buried underneath the Yucatán Peninsula in Mexico. Its center is offshore, but the crater is named after the onshore community of Chicxulub Pueblo ...
Physiology of dinosaurs. The physiology of dinosaurs has historically been a controversial subject, particularly their thermoregulation. Recently, many new lines of evidence have been brought to bear on dinosaur physiology generally, including not only metabolic systems and thermoregulation, but on respiratory and cardiovascular systems as well.
Birds are avian dinosaurs, and in phylogenetic taxonomy their over 11,000 extant species are included in the group Dinosauria. Dinosaurs are a diverse group of reptiles [note 1] of the clade Dinosauria. They first appeared during the Triassic period, between 243 and 233.23 million years ago (mya), although the exact origin and timing of the ...
Based on fossils from 1,000 dinosaur species and paleoclimate information, the new study looked at the spread of dinosaurs across different environments on Earth throughout the dinosaur era, which ...
The Woodbine Group is a geological formation in east Texas whose strata date back to the Early to Middle Cenomanian age of the Late Cretaceous. [1] It is the producing formation of the giant East Texas Oil Field (also known as the "Black Giant") from which over 5.42 billion barrels of oil have been produced. [3]
Named Gondwanax paraisensis, the four-legged reptile species was roughly the size of a small dog with a long tail, or about 1 meter (39 inches) long and weighing between 3 and 6 kg (7 to 13 pounds ...
