Cuevas De Los Murciélagos
The Cuevas de los Murciélagos are a complex of two volcanic caves on La Palma, Canary Islands. They are located at the Nacientes de Marcos y Cordero (springs of Marcos and Cordero) near the municipality of San Andrés y Sauces 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, hence the debris is very abundant and they are large blocks of terrestrial material. The caves host an important breeding colony of the Canary big-eared bat The Canary long-eared bat (''Plecotus teneriffae''), also known as the Canary big-eared bat or Tenerife long-eare ...

La Palma
La Palma (, ), also known as ''La isla bonita'' () and officially San Miguel de La Palma, is the most north-westerly island of the Canary Islands, Spain. La Palma has an area of making it the fifth largest of the eight main Canary Islands. The total population at the end of 2020 was 85,840, of which 15,716 lived in the capital, Santa Cruz de La Palma and about 20,467 in Los Llanos de Aridane. Its highest mountain is the Roque de los Muchachos, at , being second among the peaks of the Canaries only to the peaks of 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 island is the Caldera de Taburiente National Park; one of four nation ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lava Tube
A lava tube, or pyroduct, is a natural conduit formed by flowing lava from a volcanic vent that moves beneath the hardened surface of a lava flow. If lava in the tube empties, it will leave a cave. 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. Tubes form in one of two ways: either by the crusting over of lava channels, or from pāhoehoe flows where the lava is moving under the surface. Lava usually leaves the point of eruption in channels. These channels tend to stay very hot as their surroundings cool. This means they slowly develop walls around them as the surrounding lava cools and/or as the channel melts its way deeper. These channels can get deep enough to crust over, forming an insulating tube that keeps the lava molten and serves as a conduit for the flowing lava. These types of lava tubes tend to be closer to the lava erupt ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Canary Islands
The Canary Islands (; es, Canarias, ), also known informally as the Canaries, are a Spanish autonomous community and archipelago in the Atlantic Ocean, in Macaronesia. At their closest point to the African mainland, they are west of Morocco. They are the southernmost of the autonomous communities of Spain. The islands have a population of 2.2 million people and they are the most populous 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 archipelago includes many smaller islands and islets, including La Graciosa, Alegranza, Isla de Lobos, Montaña Clara, Roque del Oeste, and Roque del Este. It also includes a number of rocks, including those of Salmor, Fasnia, Bonanza, Garachico, and Anaga. In ancient times, the island chain was often referred to as "the Fortunate Isles". The Canary Islands are the southernmost region of Spain, and ... [...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 vulnerable to the risk of extinction. The species is primarily found in woodland habitat at elevations between 100 and 2300 m. 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 t ...

La Palma Giant Lizard
The La Palma giant lizard (''Gallotia auaritae'') is a giant lacertid historically living on the island of La Palma (Canary Islands, Spain); its habitat ranged from sea level up to altitudes of 800 m. It probably lives in xerophytic vegetation and is presumably an egg-laying species. Generally considered extinct in historic times, there were sightings (including photographic evidence) of a large lacertid in 2007 which may possibly correspond to this species, although these sightings have been assessed as doubtful. Taxonomy Working on fossil and subfossil evidence, this giant lizard was originally described as a subspecies of the El Hierro giant lizard (Mateo ''et al.'' 2001). Later, it was elevated to full species rank (Afonso & Mateo 2003). Specimen remains from La Palma assigned to '' G. goliath'' seem to belong to this taxon instead; if this is correct, they indicate that the average size of this species had been decreasing over the last millennia, possibly due to humans pr ...

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 palaeontology or palæontology, is the scientific study of life that existed prior to, and sometimes including, the start of the Holocene epoch (roughly 11,700 years before present). It includes the study of fossils to classify organisms and study their interactions with each other and their environments (their paleoecology). Paleontological observations have been documented as far back as the 5th century BC. The science became established in the 18th century as a result of Georges Cuvier's work on comparative anatomy, and developed rapidly in the 19th century. The term itself originates from Greek (, "old, ancient"), (, (gen. ), "being, creature"), and (, "speech, thought, study"). Paleontology lies on the border between biology and geology, but differs from archaeology in that it excludes the study of anatomically modern humans. It now uses techniques drawn from a wide range of sciences, including biochemistry, mathematics, and engineering. Us ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Caves Of The Canary Islands
A cave or cavern is a natural void in the ground, specifically a space large enough for a human to enter. Caves often form by the weathering of rock and often extend deep underground. The word ''cave'' can refer to smaller openings such as sea caves, rock shelters, and grottos, that extend a relatively short distance into the rock and they are called ''exogene'' caves. 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, microorgani ...
