Bone marrow and grease constitute an important source of nutrition and have attracted the attention of human groups since prehistoric times. Marrow consumption has been linked to immediate consumption following the procurement and removal of soft tissues. Here, we present the earliest evidence for storage and delayed consumption of bone marrow at Qesem Cave, Israel (~420 to 200 ka). By using experimental series controlling exposure time and environmental parameters, combined with chemical analyses, we evaluated bone marrow preservation. The combination of archaeological and experimental results allowed us to isolate specific marks linked to dry skin removal and determine a low rate of marrow fat degradation of up to 9 weeks of exposure. This is the earliest evidence of such previously unidentified behavior, and it offers insights into the socio-economy of the human groups who lived at Qesem and may mark a threshold to new modes of Palaeolithic human adaptation.

The importance of the nutritive value of old bones in the diet of Bearded vultures Gypaetus barbatus Margalida, Antoni; Villalba Mata, Daniel (Springer Nature, 2017)Vultures are central-place foragers and need to optimize their foraging behaviour to offset travel costs by increasing their energy gain. This process is more obvious in certain vulture species that do not feed their young ...
Regeneration of volatile compounds in Fuji apples following ultra low oxygen atmosphere storage and its effect on sensory acceptability Altisent Rosell, Rosa; Graell i Sarle, Jordi; Lara Ayala, Isabel; López Fructuoso, Mª Luisa; Echeverría Cortada, Gemma (American Chemical Society, 2008)The aim of this work was to assess whether extra time spent under AIR conditions after storage in an ultra low oxygen (ULO) atmosphere could allow the regeneration of volatile compound emission without negatively affecting ...
Effect of dietary crude protein on productive efficiency, nutrient digestibility, blood metabolites and gastrointestinal immune markers in light lambs Pelegrín, Jonathan; Serrano, Beatriz; Villalba Mata, Daniel; Martín-Alonso, María José; Bertolín, Juan Ramon; Joy, Margalida; Álvarez Rodríguez, Javier (MDPI, 2020-02-19)This study hypothesized that reducing the level of crude protein (CP) in lambs′ feed may improve nutrient utilization and did not negatively affect their productive efficiency, blood metabolites, oxidative status (OS) or ...
