Las claves cient�ficas del fascinante mundo de la Paleontolog�a de los dinosaurios. Su origen y descubrimiento, su evoluci�n, extinci�n y el mundo en que viv�an. Un recorrido exhaustivo por los interrogantes y temas m�s controvertidos, con rigor y amenidad teniendo en cuenta los descubrimientos y estudios cient�ficos m�s recientes.�Qu� hizo que los dinosaurios fuesen los amos de la tierra?, �Cu�l es el eslab�n perdido entre reptiles y aves?, �Pudo vivir alg�n dinosaurio en la Ant�rtida?, �Hubo un invierno nuclear hace 65 millones de a�os?, �Por qu�...

Biographies and bibliographies of members are included in many of the volumes. Lists of members are usually given on covers of the numbers.

In previous volumes in this series, Advances in Metal and Semiconductor Clusters, the focus has been on atomic clusters of metals, semiconductors and carbon. Fundamental gas phase studies have been surveyed, and most recently scientists have explored new materials which can be produced from clusters or cluster precursors. In this latest volume, the focus shifts to clusters composed primarily of non-metal molecules or atoms which have one or more metal atoms seeded into the cluster as an impurity. These clusters provide model systems for metal ion solvation processes and metal-ligand...
