Other groups (e.g. reptiles and amphibians, ostracods) are as yet only in the initial stages of development as a dating tool, whereas some (e.g. fish, birds) still require substantial development in order to fully explore their utility. As part of IGCP 449, vertebrate and molluscan assemblages have made important contributions to datasets from a number of areas, notably northern France, central Germany, the Czech Republic and the Ukraine. Further south, mammalian assemblages have proved useful in separating discrete periods of climatic change in Iberia and Syria. At greater distances from the core area of fluvial biostratigraphical archives, significant contributions have come from South America (Uruguay River), South Africa (Vaal) and Australia (Riverine Plain and Lake Eyre drainage basin). 1.

Although palynological studies have been of great im­ portance since the first interglacials were defined (e.g. West, 1956, 1957, 1980; Zagwijn, 1973; Turner, 1975) the rivers such as the Neckar, Ilm and Wipper, often within resolution of pollen sequences in fluvial sequences is rarely subaerial travertines interbedded with the fluvial sediments sufficient for reliable age control (cf.

Again, fluvial Thomas, 2001), a problem that led to much historical deposits on non-calcareous crystalline rocks, sand(stone)s controversy between palaeobotanists and other palaeontol­ and clays are generally lacking in useful fossils. The IGCP ogists about the number and identity of interglacials in NW project has facilitated comparison of such records over Europe (cf. Sutcliffe, 1964, 1975; Shotton, 1983; Bowen wide areas, as will be demonstrated in this paper, which et aI., 1989; Bridgland, 1994; Gibbard, 1994; Preece, 1995a, seeks to review and compare the more significant faunal 1999; Schreve, 2001a). In essence, those working with records examined. animal fossils, particularly molluscs and mammals, were In the core area of IGCP 449, NW and Central Europe, able to distinguish a greater number of interglacials and the use of mammals and molluscs for biostratigraphy is interstadials within the Middle and Late Pleistocene than well established (e.g. Lozek, 1964a, b; Stuart, 1982; the palynologists. With increasingly convincing correlation Horacek and Lozek, 1988; Horacek, 1990; Keen, 1990; between the marine oxygen isotope record and terrestrial Kolfschoten, 1990, 2000; Kovanda et aI., 1995; Preece, sequences such as those in river valleys, and supported by 1995a, 1999; Meijer and Preece, 2000), with mammalian geochronological methods wherever possible, it is the assemblages proving particularly useful for distinguishing version of the Quaternary based on mammals and molluscs the four mam post-Elsterian/Anglian interglacials that has become for many the status quo (cf.

[email protected] La hipótesis de Gaia propone que a partir de unas condiciones iniciales que hicieron posible el inicio de la vida en el planeta, fue la propia vida la que las modificó. Sin embargo, desde el inicio del Antropoceno la humanidad tiene un papel protagónico en dichas modificaciones, e.g. el aumento del CO2 en la atmósfera. Se estima que para fines de este siglo, se alcanzarían concentraciones de CO2 que el planeta no registró en los últimos 30 Ma. La información para comprender como funcionarían los sistemas terrestres con estos niveles de CO2 está contenida en los registros de períodos cálidos y en las grandes transiciones climáticas del pasado geológico.

CENTRAL AMERICAN PROVINCIALISM AND THE GREAT AMERICAN BIOTIC INTERCHANGE Michael O. Woodburne1,* Alberto L. Cione2,**, and Eduardo P. Tonni2,*** ABSTRACT The age and phyletic context of mammals that dispersed between North and South America during the past 9 m.y. is summarized. The presence of a Central American province of cladogenesis and faunal differentiation is explored. One apparent aspect of such a province is to delay dispersals of some taxa northward from Mexico into the continental United States, largely during the Blancan. Examples are recognized among the various xenar- thrans, and cervid artiodactyls. Whereas the concept of a Central American province has been mentioned in past investigations it is upgraded here. Paratoceras (protoceratid artio- dactyl) and rhynchotheriine proboscideans provide perhaps the most compelling examples of Central American cladogenesis (late Arikareean to early Barstovian and Hemphillian to Rancholabrean, respectively), but this category includes Hemphillian sigmodontine rodents, and perhaps a variety of carnivores and ungulates from Honduras in the medial Miocene, as well as peccaries and equids from Mexico. For South America, Mexican canids and hy- drochoerid rodents may have had an earlier development in Mexico. Remarkably, the first South American immigrants to Mexico (after the Miocene heralds; the xenarthrans Plaina and Glossotherium) apparently dispersed northward at the same time as the first Holarctic taxa dispersed to South America (sigmodontine rodents and the tayassuid artiodactyls).

Ade­ mas de esto la enorme riqueza en restos arqueol6gicos y paleontol6gicos hace de Trinchera Dolina un yacimiento unico, de referencia obligada para el Pleistoceno y Paleolitico de Euro­ pa. Bioestratigraficamente, el yacimiento de Trinchera Oolina (TO) puede dividirse en tres grandes unidades: la que comprende los niveles TD3 a T06; la de los niveles T07 a TOS infe­ rior y I. de TO 8 superior. T011. Palabras clave: Mamiferos, Pleistoceno. Abstract Gran Dolina is one of the Pleistocene sites located at the Sierra de Atapuerca (Spain). The Gran Dolina deposits belong to different chronological periods of the Early and Middle Pleistocene. The uppermost levels of Gran Dolina (TDII, TDIO and TD8b) contain Middle Pleistocene (post-Cromerian) macro- and micromammal assemblages. The excavation works have overpassed level TDII and have not concluded yet at TDIO: TDII is poor in macromammal remains (carnivores and herbivores) but rich in rodents. The macromammals fossil material from TDtt is very scarce and this enables (for the macromammals) definite conclusions about the chronology and type of community of these levels. The lowermost levels of Gran Dolina (TD3/4, TD5, TD6 and TD8a) contain a different mammal assemblage with typical late Early Pleistocene-Cromerian species. This radical substitution of taxa is placed at TD8 layer probably due to a stratigraphic gap in this level. The level TD6 of the Gran Dolina site contains the earliest fossil human remains of Europe, Homo antecessor, and it has also a rich and diverse micromammal assemblage.

CIONE Abstract: During the latest Pleistocene-earliest Holocene, South American terrestrial vertebrate faunas suffered one of the largest (and probably the youngest) extinction in the world for this lapse. Megamammals, most of the large mammals and a giant terrestrial tortoise became extinct in the continent, and several complete ecological guilds and their predators disappeared. This mammal extinction had been attributed mainly to overkill, climatic change or a combination of both. We agree with the idea that human overhunting was the main cause of the extinction in South America. However, according to our interpretation, the slaughtering of mammals was accom- plished in a particular climatic, ecological and biogeographical frame. During most of the middle and late Pleis- tocene, dry and cold climate and open areas predominated in South America. Nearly all of those megamammals and large mammals that became extinct were adapted to this kind of environments. The periodic, though rela- tively short, interglacial increases in temperature and humidity may have provoked the dramatic shrinking of open areas and extreme reduction of the biomass (albeit not in diversity) of mammals adapted to open habitats.
