Recent taphonomic analysis has shown that carcasses Pleistocene with different weights may be subject to similar transport strategies, suggesting that other factors influenced these choices. The hominins that occupied TD6-2 (the TD6-2 hominin group), at least sometimes, transported large carcasses to the cave in their entirety, implying participation by groups of individuals in hunting parties. These individuals delayed their consumption of large amounts of food, instead moving it to Gran Dolina, where it was shared with other group members. These decisions are evidence of social cooperation and food sharing amongst early European hominins. Ó 2011 Elsevier Ltd. All rights reserved. Introduction 1994; Milo, 1998, 2005), c) carnivore gnawing and ravaging (e.g., Binford, 1981; Marean and Spencer, 1991; Marean et al., 1992; It is uncommon to find whole carcasses in archaeological Blumenschine and Marean, 1993; Madrigal and Holt, 2002; assemblages. Anatomical connections are usually scarce, with Munson and Garniewicz, 2003; Marean and Cleghorn, 2003; Faith a high level of broken remains and a bias in the animals’ anatomical and Behrensmeyer, 2006), and/or d) differential destruction of profiles. This may be due to: a) hominins selecting certain elements some bones or their portions by post-depositional processes (e.g., for transport (e.g., Yellen, 1977; Binford, 1978; Bunn and Kroll, 1986; Brain, 1981; Klein and Cruz-Uribe, 1984; Marean, 1991; Lyman, O’Connell et al., 1988, 1990; Gifford-Gonzalez, 1993; Oliver, 1993; 1994). The aforementioned causes can hinder the reconstruction of Monahan, 1998; Faith and Gordon, 2007), b) activities that occur at the original anatomical composition. the home base, e.g., bone cooking, cremation, bone breakage and/or Skeletal-part profiles can help to interpret the type of access to food sharing (e.g., Todd and Rapson, 1988; Blumenschine and animals (Bunn and Ezzo, 1993) and the transport strategy patterns Selvaggio, 1988; Gifford-Gonzalez, 1993; Oliver, 1993; Marshall, used by Pleistocene hominins.

These opposing interpretations of Hadza carcass transport after studying factors can lead to various results in the archeological record, similar samples obtained in relatively similar time frames, which are sometimes superimposed. These superimpositions can demonstrates this problem. These contradictions are partially due hinder the legibility of archaeological assemblages from specific to their use of different study methods. They did agree on issues events and when combined with the possible involvement of such as the relationship between transport type and animal weight, other agents, makes inferences about subsistence strategies by and the dependence of the final decision about bone transportation prehistoric hominins very difficult. This paper presents on fat and marrow content. Bunn (1993) also found a link between a zooarchaeological perspective on an updated analysis of the several decisions and the anatomy of specific species regardless of remains from Level TD6-2 at Gran Dolina (Sierra de Atapuerca, the animal’s weight.

Monahan (1998) concluded previous study of TD6-2 (Díez et al., 1999) proposed that the that the Hadza do not transport the carcasses on the basis of the transport decisions made by H. antecessor were related to prey schlepp effect (i.e., tendency to only transport limbs, Perkins and weight.

According to Monahan (1998: 422), the anatomical profiles of the items transported based on animal weight: “.do not reflect a single, uni-modal pattern of carcass The Gran Dolina site and Level TD6-2 transport, but the sum total of different transport modes”. Addi- tionally, the distance between the kill/butchering site and the home Gran Dolina is a cave located in the Railway Trench (Sierra de base (Bunn and Kroll, 1988; O’Connell et al., 1990; Monahan, 1998), Atapuerca, Burgos, Spain).
