Excavations at Cova Bonica (Barcelona, Spain) have revealed 98 human remains, grouped into five age clusters and corresponding to a minimum of six non-articulated individuals. The remains are clearly associated with Cardial pottery, lithic artifacts, and ornaments suggesting an Early Neolithic horizon. The radiocarbon dating of three human individuals provides a reliable attribution to this period, with a range between ca. 5470 and 5220 cal b.c., identifying it as one of the few assemblages of human remains directly dated from this period. These remains correspond to a rare collective human inhumation and join a growing body of samples from the Cardial Neolithic, which is providing some of the important sites for the study of population movement and the spread of Neolithization along the western Mediterranean coast. 相似文献
Beu, A.G., August 2016. Molluscan death assemblages from uplifted Holocene terraces, Mahia Peninsula, New Zealand, interpreted from present-day intertidal ecology. Alcheringa 41, xxx–xxx. ISSN 0311-5518.
Macrofossils from cover beds of marine terraces at Table Cape, Mahia Peninsula, uplifted coseismically ca 250, 1400, 1850 and 3500 years ago are compared with the fauna living on the nearby 200-m-wide intertidal rock platform. The inner platform is dry at low tide, apart from shallow pools containing Diloma aethiops and abundant but unexpected specimens of Zeacumantus subcarinatus and Cominella glandiformis exposed to the sun; all are common fossils in the terrace cover beds. The outer platform is carpeted densely with the alga Hormosira and shelters a diverse fauna, again all common fossils in the terrace cover beds. Sand and gravel containing shell fragments and supporting Zostera sea-grass turf unexpectedly covers ca 5% of the platform in low areas along the east coast. The fossil fauna is listed from 47 samples from two trenches excavated east–west and north–south through the terrace cover beds. Death assemblages of 158 molluscs, including 24 new records as fossils, and 11 taxa in other phyla delimit sediment derived from four shell accumulation sites identified around the present cape: storm beach, high-tidal strand line, hollows in the rock platform and Zostera flats. Up to 32 of the 47 samples (68%) possibly were deposited in Zostera flats; the rest were sand beach accumulations deposited at and near the high-tidal strand line. All fossils common in the cover beds lived on the rock platform. Differences between the deposits in the two trenches result from two factors. Protection along the east coast by protruding tephra beds and an outer rampart armoured with the macroalga Durvillaea prevented erosion of Zostera-supporting sediment which, therefore, was retained after each uplift event. The exposed eastern position of Table Cape also caused sediment to be transported predominantly westwards, onshore on the east coast but away from Table Cape along the north coast.

The term karst derives from the Kras plateau, which is in the northwestern part of the area now known as the Dinaric Karst. The landscape consists mostly of Mesozoic carbonate rocks and stretches along the Adriatic Sea coast for a distance of 600 km. Although the region lies parallel to the sea, the Mediterranean temperature influence is limited to a narrow coastal belt, except for the amount of precipitation, which can reach 5000 mm yr?1. Forests belonging to the Mediterranean and Euro‐Siberian – North American region, covered the primary Dinaric Karst. Human deforestation of the Karst began during the Neolithic period, 6500–6000 BC. Throughout history there have been two main reasons for deforestation; economic (the requirements of new land, pastures, timber use and trade), and social (local increases in population, mass migration, wars, raids). Mankind's perception of forest protection and preservation can be traced through documents going back to the 12th century. Reforestation is mentioned in some of them, but successful reforestation did not begin until the 1850s. Nowadays dense natural forests, extensive forest plantations, dry karst shrublands and also completely barren karst areas can all be found on the Dinaric Karst. 相似文献
