The state of the art knowledge palaeontological biospeleològic and vegetation pteridofítica briofítica and the cavities of the Sierra Na Burguesa (Tramuntana, Majorca) are know. In this mountain karstic deposits we are found and studied Quaternary vertebrate fossil important how the case Myotragus batei. The briophytic and pteridophytic flora of entries cavities are not important, except Clot des Cero whit Homalia lusitanica and Asplenium scolopendrium. Regarding invertebrate fauna, there are endemic Entomobrya vadelli, only know from this cave, and vertebrate stressed the importance of caves as Pilar with the bat Miniopterus schreibersii station.

The state of the art about speleogenetic, topographic and mining knowledge of the Sierra Na Burguesa (Tramuntana, Majorca) are given. Over 160 cavities are topographied. The most important is l'avenc de l'Infern with 827 m of round, the covota des Puig Gros de Bendinat with 593 m, the coves del Pilar with 531 m. About the depth, l'avenc de l'Infern with 132 m and l'avenc de sa Soca with 103 m are the most important. The cavities speleogenesis of the mountains is linked to the dissolution of carbonates and gypsum in the Secondary rocks. The mining activity to obtain plaster has been important from XVIII century. The mines are presented in the open or in galleries. Today, a lot of then are abandoned.

Littoral caves can be found at the erosion coasts of the Balearic Islands. The genesis of most of these caves are produced by the marine erosion and they are known as marine abrasion caves. These caves generally have small dimensions (usually no longer than 50 m), display ascending pro-files and can produce blowholes, tunnels and arches. Although they have initially nothing to do with karst, several karstic or karst-related processes can act on these caves, and speleothems, karstic fillings, dissolution phenomena, etc., can be observed inside them. Also cave fauna can be found.

The first speleological explorations in the Balearic Islands date back from the early XIXth century, years in which the activities were performed in a very precarious way, entering the caves with torches and descending the shafts with complicated systems of ropes and pulleys. In the past two centuries the evolution has been constant, embracing both the material used for the explorations as well as the technical training of the cavers. In order to contextualize the speleological explorations in the Balearic Islands, five different stages have been distinguished: the pre-speleology, or times prior to the birth of caving properly said; the pioneers epoch, in which leading figures of international renown must be highlighted; the Catalan caving campaigns, conducted in quite special brilliant moments of speleology in Catalonia; the conventional Mallorcan speleology period, was the explosion of caving in the Balearics characterized by a huge topographic activity and by the invaluable collaboration between different clubs of cavers; and, finally, the impact of underwater Mallorcan caving, stage that is marked by the beginning of the speleo-diving campaigns in the island and by outstanding explorations and discoveries of large cavities, such as Cova des Pas de Vallgornera and Cova de sa Gleda. The Federació Balear d'Espeleologia (Balearic Federation of Speleology) was not formed until 1982, however, a few years earlier, in 1972, the caving clubs were organized within the Balearic Delegation of the Comité Catalano-Balear d'Espeleologia. This year 2011, the Federació Balear d'Espeleologia has received the Ramon Llull award, which grants the Govern de les Illes Balears, in recognition of the valuable contributions to the scientific knowledge of our nature, made by many self-taught members of the federation and without any economic benefit.

This contribution of the absolute chronology for the Beaker culture presents the results of archaeological research that took place at Coval Simó (Mallorca) between 1998 and 2008. Coval Simó is a rockshelter situated at the summit of one of the mountains that forms part of the northern mountain range of the Serra de Tramuntana. The site provided an exceptional undisturbed context, shielding a small space of only 25 m2. Thin sedimentary layers were deposited in a short timespan and later were sealed off by large blocks due to a rockslide falling from the top of the rockshelter. This site has offered significant information related to the occupation of a human group linked to the Bell Beaker culture, and users of other distinctive undecorated pottery vessels. Direct evidence of early island metallurgy was also obtained: smelting slags from local copper minerals. Regarding the methodology used for analysis, short-lived samples were chosen for radiocarbon dating, consisting of bone fragments identified and classified taxonomically. The samples were submitted alternately to two different 14C laboratories and the obtained results point to a clear horizon for the early human occupation of the site, ranging between about 2300 and 1900 cal BC. © 2014 by the Arizona Board of Regents on behalf of the University of Arizona.
