Witnesses of the early Pliocene sea-level rise in the Manilva Basin (Málaga, S Spain)

The Sierra de la Utrera, a relief in the Manilva Basin (Malaga, SW Spain), shows bored surfaces at different heights above present-day sea level, from 96 m to 287 m. Borings occur in the eastern, central, and western parts of the Canuto de la Utrera, a prominent gorge in the central southern part of the relief excavated in Mesozoic limestones, as well as on the western end of the Canuto Chico, a smaller canyon in the northern part. Pliocene marine deposits fossilized the bored surfaces. Bored boulders of the substrate are embedded in the Pliocene sediments. The traces Gastrochaenolites ispp., Entobia ispp., Caulostrepsis ispp., Circolites kotoucensis, and Ericichnus asgaardi have been ident…

The negligence and lazy of the Administration: the greatest danger to the conservation of the unique lagerstätte sites

An example is given of one of the most important sites in the Spanish fossil record, such as the almost a hundred moulds of ancient jellyfish of hydrozoan Medusozoa, Cnidaria, exceptionally preserved in an arkosic greywacke bedding plane of the Corduban/Terreneuvian Epoch (lowermost Cambrian) in the municipal district of Constantina (Seville). In spite of its scientific-patrimonial importance and the fact that it has been brought to the attention of the Andalusian autonomous administration for more than twenty-five years, it has still not been the object of an adequate legal protection figure. This lack of interest or bureaucratic slowness is causing an irreparable loss in many of its eleme…

The Palaeontological heritage of Ribeira de Cacela (Algarve, Portugal). Its preservation in the Portuguese context

The protection of palaeontological heritage is justified by its own specificity, which results from its limited visibility, spatial variability, irreproducibility and importance as a record of past biodiversity. Until the present in Portugal the laws concerning the preservation of natural areas are focused mainly on the protection of threatened living species and their habitats, neglecting any geological aspect, and even less the concept of palaeontological heritage. The present analysis refers to the fossil-site of Ribeira de Cacela, included in the Natural Park of Ria Formosa (Algarve, southern Portugal), which represents a site of great paleontological interest. No particular palaeontolo…
