In the Roman world, as in many other cultures, ivory was perceived as raw material suitable for the carving of prestigious personal items. The types of Roman and Late Antique carved ivory objects that survived as well as their quantity and stylistic range is probably a result of their preservation contexts as well as their appreciation and sometimes ongoing use in later epochs. Regarding ivory combs decorated with bas-relief carvings, only nine specimens are ascribed to the Mediterranean and NW-Europe during Late Antiquity, all exclusively present biblical iconography. Information about their origin, object history and age is usually very limited. The first evidence that hunting scenes were still part of the ivory carving tradition in Late Antiquity is provided by a comb discovered in a mid-6th-century male inhumation burial at Deiningen, Nördlinger Ries. In addition to stylistic and technological comparison, SEM-imaging, ZooMS, ancient DNA (aDNA) sequencing and 87Sr/86Sr isotope ratios were applied to identify the species and possible origin. While size and structure point toward Loxodonta africana as a likely source, poor preservation of the material hindered more refined results by ZooMS or aDNA analyses and consequently a precise triangulation of the source area in combination with the strontium isotope ratios. Besides being a singular piece of craftsmanship, the ivory comb fits into an assumed network of production and distribution that spanned from Northern Africa to the Frankish realm north of the Alps.

Benthic organisms are important ecological receptors, playing fundamental roles across seafloor ecosystems, delivering some of the most important functions in the marine environment. Some of these key benthic functions include nutrient cycling, food provision for higher trophic levels, and carbon storage. Over the past 6 years, benthic monitoring has faced growing complexity, driven by diminishing funding and the constraints imposed by the COVID-19 pandemic. These challenges underscore the pressing need to recognize the enduring value of benthic time series in supporting monitoring, management, and modelling efforts. These long-term data sets have been critical to advance our current understanding into the areas of cumulative effects, conservation, management of Marine Protected Areas (MPAs), development of indicators, and assessment of climate-driven changes in marine ecosystems. Ongoing expert group discussions consistently affirm both the relevance and necessity of continuing to collect these vital data sets. However, the focus on emerging technologies and so-called ‘cutting-edge’ approaches sometimes leads to the undervaluation and compromising some of these long-term series. We contend that a comprehensive understanding of benthic ecology, essential for robust marine management, reliable numerical analysis, and taxonomic consistency, cannot be achieved without the continuity provided by long-term data. Such time series are indispensable for tracking patterns of change and assessing responses across diverse human activities and seafloor ecosystems. While our research has concentrated on soft sediment environments, many of the key principles and recommendations outlined here are broadly applicable to other ecosystem types.
