The publication of the present work - rightly designated as the book of Arrabida's nomination file for inscription on the World Heritage list - has for all of us a special significance as it represents, in a sense, the culmination of a complex, challenging and rewarding process. As is widely known, the Arrábida is included since 2004 in UNESCO's Portuguese tentative list, with AMRS being one of this process' promoters. It wouldn't be appropriate to describe here all the details, but it is fair to say that since 2004 to the present day, we've come a long way in recovering and valuing the Arrábida. It is with sincere satisfaction that we can say: our knowledge of the Property is now deeper, up to date and much more accurate, doing justice to the exceptional values contained within the Arrábida - which is well expressed in the work now published, based on researches and works of the highest scientific value. This is also a regional development project, to value our lands, people and the natural and cultural heritage. The Setúbal's Peninsula is a region that contains within its territory a vast natural and cultural heritage, being the Arrábida one of the most beautiful and significant natural areas in the Mediterranean. The Arrábida Mountain is a place with its own identity, being the result of a long history of Man's adaptation to Nature. It is a place of unmistakable aesthetic beauty, a unique place where nature and culture intertwine; it is a place of contrasts, of land and sea, sky and mountains, a place of combined actions by Man and Nature. Place of vibrant social practices, of rituals and festivals, of knowledge, of representations and expressions, of instruments, objects and artifacts. Place with a history that must be preserved and bequeathed to future generations. Place with monuments of vanished civilizations, but also of living traditions. These are some of the values supporting the Arrábida's nomination for the World's Heritage list. It is a complex and demanding nomination file, which this work is an illustrative sample of. A mixed application - as it includes both the natural and cultural heritage - which, given the richness and uniqueness of the Property in question, is fully justified. It is our profound conviction that this Nomination streamlines the potential of our region, bringing benefits not only to the local population, but also to the whole country. To that extent, it is also a sign of hope and confidence showing that it is possible to build a different future; that by investing in our people, in their abilities, knowledge and traditions, it is possible to create a sustainable development; that is possible to leave for future generations a legacy of which we are proud of having worked on. To be able enjoy this magnificent edition is a step in that direction.

Portugal has been providing dinosaur remains since, at least, 1863. The 18th century tiles depicting the legend of Our Lady in Cabo Espichel are probably the oldest known dinosaur track illustration. To our knowledge, the first remains found in Portugal were theropod teeth collected near Porto das Barcas (Late Jurassic of Lourinhã) in June 20th, 1863 by the geologist Carlos Ribeiro (1813-1882). The first dinosaur paper was written by Henri Sauvage (1842-1917) published in 1896. All remains collected since 19th century were gathered in a work signed by Albert de Lapparent (1905-1975) and Georges Zbyszewski (1909-1999 ) titled Les Dinosauriens du Portugal (1957) that was a significant milestone in the Portuguese dinosaur paleontology and gives the state-of-the-art by the time. Several dinosaurs are named, described, depicted and mapped in that monograph. The first track record is given by Jacinto Pedro Gomes (1844-1916) in 1916. Concerning the non-scientific literature referring to dinosaurs, in 1884 the newspaper Occidente reports the Bernissart findings in Belgium. In the 1959 occurs the first visit to Portugal of Walter Kühne (1911-1991) from the Free University of Berlin. Further visits and work granted the access to the Guimarota Mine and other Late Jurassic deposits in the 1960’s, 70’s and 80’s with a high number of publications. In the 1980’s and early 1990’s starts a progressive era for dinosaur paleontology in Portugal with the works of Peter Galton, Miguel Telles Antunes, the Natural History Museum, the Museum of Lourinhã and the New University of Lisbon, Oliver Rauhut, and others.

The quadrate in nonavian theropods is incredibly diverse morphologically; however this morphological disparity has been underestimated for taxonomic purposes. The quadrate topological homologies and anatomy, as well as the terminology, among nonavian theropod clades are reviewed. In order to evaluate the phylogenetic potential and investigate the evolutionary transformations of the quadrate, we conducted a Catalano-Goloboff phylogenetic morphometric analysis using 3 morphometric characters, a total of 28 landmarks coded for 23 taxa, as well as a cladistic analysis using 115 discrete quadrate-related characters coded for 43 taxa. The cladistic analysis provides a fully resolved tree mirroring the current classification of nonavian theropods. The quadrate morphology by its own provides a wealth of data with strong phylogenetic signal. Several unambiguous synapomorphies support nonavian theropod relationships and the resulting consensus tree allows inference of major trends in the evolution of this bone. Important synapomorphies include: for Abelisauridae, a lateral ramus extending to the ectocondyle; for Tetanurae, the absence of the lateral process; for Spinosauridae, a medial curvature of the ventral part of the pterygoid ramus occurring just above the mandibular articulation; for Neotetanurae, an anterior margin of the pterygoid flange formed by a roughly parabolic margin; and for Tyrannosauroidea, a semi-oval pterygoid flange shape in medial view. The Catalano-Goloboff phylogenetic morphometric analysis reveals two main morphotypes of the mandibular articulation of the quadrate linked to function. The first morphotype, characterized by an anteroposteriorly broad mandibular articulation with two ovoid/subcircular condyles roughly subequal in size, is found in Ceratosauria, Tyrannosauroidea and Oviraptorosauria. This morphotype allows a very weak displacement of the mandible laterally. The second morphotype is characterized by an elongate and anteroposteriorly narrow mandibular articulation and a long and parabolic/sigmoid ectocondyle. Present in Megalosauroidea, Allosauroidea and Dromaeosauridae, this morphotype permits the lower jaw rami to be displaced laterally when the mouth opened.

Recent excavations at the Maastrichtian locality of Bentiaba, Namibe Province, in the southern part of Angola, have yielded high quality and partially articulated plesiosaur specimens that indicate at least three taxa were present. A new elasmosaurid is the most abundant and well-preserved plesiosaur taxon at Bentiaba. It is known from a complete articulated paddle and other elements of the skeleton, many of which remain to be collected. The most diagnostic elements so far recovered are the complete pelvic and pectoral girdles, which indicate that the Bentiaba elasmosaurid is probably a new genus because it bears an asymmetrical ventral process of the coracoids, a complete cordiform posterior coracoid vacuity, and pronounced excavation of the anterior border of the coracoids, among other characters. A polycotylid is [...]
