- Built-in smartphone LiDAR for archaeological and speleological researchPublication . Antón, Daniel; Mayoral-Valsera, Juan; Simón-Vallejo, María Dolores; Parrilla-Giráldez, Rubén; Cortés-Sánchez, MiguelLiDAR technology is reshaping cave surveying by providing detailed 3D models that enhance the accuracy of morphological and rock art digitisation and reduce subjective interpretation. This technology, in its varied forms and solely or combined with other remote sensing techniques such as photogrammetry, enriches the documentation and supports multidisciplinary research by enabling spatial analyses and virtual exploration, thus opening new possibilities in various fields such as archaeology, geology, speleology, tourism or education. In this sense, this research aimed to democratise the use of low-cost mobile LiDAR (Light Detection and Ranging) 3D scanning, subjected to fewer accessibility limitations than tripod-mounted Terrestrial Laser Scanners (TLS), in cave archaeology and speleology. For this purpose, La Pileta Cave in M´ alaga (Spain) was chosen as a case study. Declared a Spanish National Monument in 1924, the cave boasts one of the greatest collections of prehistoric art in Europe and, therefore, a reference in South Iberia, and outstands out for its varied karstic morphologies. The research methodology involved a systematic process to ensure clarity and accuracy. First, the main itinerary in La Pileta was scanned using the smartphone LiDAR technique. This was followed by a Terrestrial Laser Scanning (TLS) survey of a specific sector within the same itinerary, with numerous morphological details of its karstic environment and important Palaeolithic rock art samples. Both the smartphone LiDAR and TLS spatial data were then validated against a Ground Control Points (GCPs) network previously established using a total station. Given the higher accuracy of TLS for graphical documentation, it was further employed as a benchmark to validate the accuracy of smartphone LiDAR. Despite its limitations, this research revealed smartphone LiDAR as a suitable technique for geometric data recording in cave archaeology and speleology. Solely or combined with TLS, mobile LiDAR can be used to document rock art panels in karstic environments, surpassing the latter technique in terms of texture quality. In addition to the accurate graphic documentation carried out in the cave sector, this research broke down the advantages and disadvantages of the smartphone LiDAR technique and provided a series of recommendations for its use in this context.
- Living on the shores of the Alboran sea. The neolithic on the coast of Málaga (Spain) a multiproxy approachPublication . Simón-Vallejo, María D.; Lozano-Francisco, M. Carmen; Riquelme-Cantal, José A.; Macías-Tejada, Sara; Camuera, Jon; Uzquiano Ollero, Paloma; Sánchez Marco, Antonio; Garrido-Anguita, Juan M.; Jiménez-Espejo, Francisco; Parrilla-Giráldez, Rubén; Vera-Lozano, José A.; Vera-Peláez, José L.; Cortés-Sánchez, MiguelContext: The coast of Málaga is one of the core areas for the Neolithic in southern Iberia with the earliest occupations dating to the middle of the 8th millennium cal BP. From the outset, evidence shows a fully developed and highly diversified system of agriculture and animal husbandry. The palaeoenvironmental conditions during this period in the southern Iberian Peninsula reveal phases of aridity. Objectives: This study aims to understand how Neolithic communities adapted to these adverse environmental conditions. It also explores the role of wild resources and seasonal patterns in subsistence strategies. Methods: A multiproxy approach was applied, combining regional palaeoenvironmental data with archaeological, archaeofaunal, archaeobotanical and anthropological evidence. The analysis focuses on sites located near aquifer discharges. Results: Fully developed and highly diversified agriculture and herding practices are documented from the earliest Neolithic phases. The challenges posed by arid conditions appear to have been mitigated by settlement in areas linked to major aquifer outlets and by the cultivation of drought-resistant cereals. Multiple lines of evidence suggest a seasonal pattern of occupation, primarily from late autumn to early summer, when marine resources were likely exploited. Neolithic groups may have engaged in regular hunting and gathering activities or maintained interactions with local Epipalaeolithic–Mesolithic populations. Agricultural and pastoral management emerge as key factors for evaluating the contribution of wild resources to their subsistence. Conclusions: The integration of environmental, archaeological and biological records provides a more holistic perspective and better understanding of Neolithic economy and society along the Málaga coast between c. 7.6th—5th millennium cal BP, offering insights into subsistence strategies under arid conditions in a coastal setting.
