“…Over the last 50 years, radiocarbon dating has been the most widely used numerical dating technique in Quaternary science and especially in Holocene environmental reconstruction (Taylor 1997; Trumbore 2000; Walker 2005). In many research contexts, the dependence of radiocarbon dating on organic sediments has not proved a fundamental limitation.…”

Matthews, J. A. & Winkler, S. 2010: Schmidt‐hammer exposure‐age dating (SHD): application to early Holocene moraines and a reappraisal of the reliability of terrestrial cosmogenic‐nuclide dating (TCND) at Austanbotnbreen, Jotunheimen, Norway. Boreas, 10.1111/j.1502‐3885.2010.00178.x. ISSN 0300‐9483. Schmidt‐hammer exposure‐age dating (SHD) and terrestrial cosmogenic‐nuclide dating (TCND) are complementary techniques that can be used for mutual testing. SHD is low‐cost but requires local control points of known age and may be affected by local geological variation and other environmental factors that influence weathering rates. TCND is vulnerable to the occurrence of anomalous boulders, other geomorphological uncertainties and the effects of snow‐shielding at high altitudes. Both techniques are sensitive to post‐depositional disturbances if other than solid bedrock is sampled. SHD was applied to two moraine ridges beyond the Little Ice Age limit of Austanbotnbreen in the Hurrungane massif, southern Norway. Independent regional and experimental local age‐calibration curves were used to reappraise previous TCND results. Neither the two boulder surfaces nor their proximal bedrock surfaces could be differentiated statistically in terms of SHD exposure ages or their mean R‐values (±95% confidence intervals), which ranged from 40.73±1.72 to 43.34±0.69. The best of the independent regional‐calibration curves produced SHD exposure ages of 9413±723 and 9304±602 years, which are consistent with moraine formation early (c. 10.2 ka) and late (c. 9.7 ka) within the late‐Preboreal Erdalen Event. The current precision of SHD, as reflected in 95% confidence intervals of ±500–900 years, enables rejection of a Finse Event (c. 8.2 ka) age for either moraine. Results are consistent with a retracted Austanbotnbreen between the Erdalen Event and the Little Ice Age, and a modified model of Neoglaciation.

During a survey of the historical collections stored at the Herbarium of the Facolta' di Agraria, Universita' di Napoli (PORUN), we found 170 specimens of unknown provenance mixed within the surviving Domenico Cirillo’s herbarium (18th century). These 170 specimens were strikingly different from the rest and had never been studied previously. From an initial close examination, we suggested that they may date back to the 16th to 17th century, and likely have been part of Ferrante Imperato’s historical herbarium. To test our initial hypothesis, we employed an empirical approach to assess the age and provenance of these specimens. First of all, we assembled the available literature regarding the history of Italian botanical collections and collectors from the 16th to the 18th century in the political context of those years. We integrated our historical reconstruction with results obtained by radiocarbon analyses of the specimens and mounting paper, and watermark and paleographic analyses. Our combined results are consistent with the hypothesis that these unknown specimens may have been part of an 80 volumes herbarium that belonged to Ferrante Imperato, one of the earliest natural historians of our times. Our integrated methodology is novel in the field of historical specimen research and was critical in generating our final conclusions.

“…It has profoundly affected the archeology field, frequently portrayed as the radiocarbon shift. Taylor said [20] "14C data made a world prehistory possible by contributing a time scale that transcends local, regional and continental boundaries". Space radiation generates neutrons that penetrate the atmosphere of our planet.…”

Abstract-The field of archeology is undoubtedly left behind in the mobile era compared to other scientific domains. The deployment of mobile technology solutions is of meagre contribution to the field. In fact, almost no mobile apps are designed as per archeologists' work requirements in the excavation site. This study aims to tackle this dilemma through a roadmap to pave the way for the community to recover this digital divide. The roadmap encompasses a comprehensive methodology on how to develop mobile apps that meet the requirements of its respective audience. The development of two apps is introduced to illustrate the implementation of the methodology. The result of adopting this 'roadmap' study improves the data collection, processing and usage. It enhances information accuracy and sharing. Besides, it reduces the 'destructive' aspect of the archeology investigations and provides archeologists with handy solutions that they can use ubiquitously. The refinement of the first versions of mobile apps for archeology will make the measurements more accurate and improve the level of maturity of the field vis-à-vis the mobile technology sector. Most significantly, this study opens the door, eventually, for a new era wherein the community starts by deploying mobile technology solutions to ultimately go beyond the current dating techniques, such as the radiocarbon dating method. An ultimate future work could be the exploration of developing mobile apps, in an interdisciplinary context, that measure the age of archeological items by few clicks and prepare the field for the forthcoming post-device era.
