Cuevas De Los Murciélagos in the north of the island. Cueva de los Murciélagos I is located in an altitude of 1220 m, Cueva de los Murciélagos II in an altitude of 1000 m. Both caves have a length of 100 m. The access is not difficult. Though it is a descending tube it is good to walk. On the endpoint of the Cueva de los Murciélagos I is a small firepit in the soil which is slightly more complicated to access. In some areas it has a steep slope. It's a rather old cave where erosion caused by the years is evident, he ...

La Palma
La Palma (, ), also known as ''La isla bonita'' () and historically San Miguel de La Palma, is the most northwesterly island of the Canary Islands, a Spanish autonomous community and archipelago in Macaronesia in the North Atlantic Ocean. La Palma has an area of making it the fifth largest of the eight main Canary Islands. The total population at the start of 2023 was 84,338, of whom 15,522 lived in the capital, Santa Cruz de La Palma and 20,375 in Los Llanos de Aridane. Its highest mountain is the Roque de los Muchachos, at , being second among the peaks of the Canaries after the Teide massif on Tenerife. In 1815, the German geologist Leopold von Buch visited the Canary Islands. It was as a result of his visit to Tenerife, where he visited the Las Cañadas caldera, and then later to La Palma, where he visited the Taburiente caldera, that the Spanish word for cauldron or large cooking pot – "caldera" – was introduced into the geological vocabulary. In the center of the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lava Tube
A lava tube, more rarely called a pyroduct, is a 'roofed conduit through which molten lava travels away from its vent'. If lava in the tube drains out, it will leave an empty cave. Lava tubes are common in low-viscosity volcanic systems. Lava tubes are important as they are able to transport molten lava much further away from the eruptive vent than lava channels. A tube-forming lava flow can emplace on longer distance due to the presence of a solid crust protecting the molten lava from atmospheric cooling. Lava tubes are often considered when preparing hazard maps or managing an eruptive crisis. Formation A lava tube is a type of lava cave formed when a low-viscosity lava flow develops a continuous and hard crust, which thickens and forms a roof above the still-flowing lava stream. Three main formation mechanisms have been described: (1) roofing over a lava channel, (2) pāhoehoe lobe extension or (3) lava flow inflation. # When it erupts from a vent, lava usually flow ...

Canary Islands
The Canary Islands (; ) or Canaries are an archipelago in the Atlantic Ocean and the southernmost Autonomous communities of Spain, Autonomous Community of Spain. They are located in the northwest of Africa, with the closest point to the continent being 100 kilometres (62 miles) away. The islands have a population of 2.25 million people and are the most populous overseas Special member state territories and the European Union, special territory of the European Union. The seven main islands are from largest to smallest in area, Tenerife, Fuerteventura, Gran Canaria, Lanzarote, La Palma, La Gomera, and El Hierro. The only other populated island is Graciosa, Canary Islands, La Graciosa, which administratively is dependent on Lanzarote. The archipelago includes many smaller islands and islets, including Alegranza, Islote de Lobos, Isla de Lobos, Montaña Clara, Roque del Oeste, and Roque del Este. It includes a number of rocks, including Roque de Garachico, Garachico and Roques de ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Canary Big-eared Bat
The Canary long-eared bat (''Plecotus teneriffae''), also known as the Canary big-eared bat or Tenerife long-eared bat, is a species of vesper bat endemic to the Canary Islands. According to the IUCN, it is critically endangered. It feeds mainly on moths. Roosting sites include caves, lava tubes and abandoned buildings. Taxonomy and etymology It was described as a new species in 1907 by British mammalogist Gerald Edwin Hamilton Barrett-Hamilton. He described it based on specimens in the British Museum of Natural History. The holotype had been collected by R. Gomez in April 1887 near the town of La Orotava. "R. Gomez" was likely Ramon Gomez, a local pharmacist who traded in medicines, old coins, and biological specimens from the Canary Islands. Its species name "''teneriffae''" is derived from Tenerife, which is one of the islands of the Canary Islands and the place where the holotype was collected. Description When Hamilton described it as a new species, he noted that it was sim ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
La Palma Giant Lizard
The La Palma giant lizard (''Gallotia auaritae'') is a large wall lizard endemic to the island of La Palma in the Canary Islands, currently extinct or critically endangered. History Subfossil remains indicate that it occurred once through the island, up to 800 meters above sea level, and that its preferred habitat was xerophytic vegetation. Though described originally from bones in 2001 and generally considered extinct, sightings and photographic evidence of a large lacertid made in 2007 north of the island could belong to this species. Some authors consider the sightings doubtful. Taxonomy The La Palma giant lizard was described originally as a subspecies of Simony's giant lizard (''G. simonyi''),Mateo, J.A.; García-Márquez, M.; López-Jurado, L.F. & Barahona, F.

Trias Greenfinch
The Trias greenfinch (''Chloris triasi'') is an extinct passerine from the family of finches (Fringillidae). The fossil remains were unearthed in the Cuevas de los Murciélagos near San Andrés y Sauces in the north of La Palma, Canary Islands. The species epithet commemorates Spanish palaeontologist Miquel Trías who collected the holotype together with Josep Antoni Alcover in July 1985. Description The holotype is an almost complete cranium with both pterygoids but lacking mandible, quadrate bones, and the palatine process of maxilla. The paratypes include a proximal fragment of a right humerus, a distal fragment of a right humerus with a prominent fragmented epicondyle, a left ulna lacking the epiphyseal plate, an almost complete right ulna lacking the olecranon and a complete left carpometacarpus. The cranium length is 34,89 mm, the cranium width is 17,47 mm and the cranium height is 14,31 mm. The maxilla length is 19,10 mm, the maxilla width is 9,67 ...

Paleontological Sites Of Europe
Paleontology, also spelled as palaeontology or palæontology, is the scientific study of the life of the past, mainly but not exclusively through the study of fossils. Paleontologists use fossils as a means to classify organisms, measure geologic time, and assess the interactions between prehistoric organisms and their natural environment. While paleontological observations are known from at least the 6th century BC, the foundation of paleontology as a science dates back to the work of Georges Cuvier in 1796. Cuvier demonstrated evidence for the concept of extinction and how life of the past was not necessarily the same as that of the present. The field developed rapidly over the course of the following decades, and the French word ''paléontologie'' was introduced for the study in 1822, which was derived from the Ancient Greek word for "ancient" and words describing relatedness and a field of study. Further advances in the field accompanied the work of Charles Darwin who popula ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Caves Of The Canary Islands
Caves or caverns are natural voids under the Earth's surface. Caves often form by the weathering of rock and often extend deep underground. Exogene caves are smaller openings that extend a relatively short distance underground (such as rock shelters). Caves which extend further underground than the opening is wide are called endogene caves. Speleology is the science of exploration and study of all aspects of caves and the cave environment. Visiting or exploring caves for recreation may be called ''caving'', ''potholing'', or ''spelunking''. Formation types The formation and development of caves is known as ''speleogenesis''; it can occur over the course of millions of years. Caves can range widely in size, and are formed by various geological processes. These may involve a combination of chemical processes, erosion by water, tectonic forces, microorganisms, pressure, and atmospheric influences. Isotopic dating techniques can be applied to cave sediments, to determine the time ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
