“…In spite of this, this approach constitutes the main source of paleoclimatic information available for the Mediterranean region. Another MA-based approach, the coexistence approach (Mosbrugger & Utescher, 1997;Utescher et al, 2014), has also been used in the Iberian Peninsula and some circum-Mediterranean regions (e.g., Casas-Gallego et al, 2021;Mahler et al, 2022), but not as extensively as the climate amplitude method. The development of mangrove vegetation was specifically analyzed within a Northern Hemispheric context (Popescu et al, 2021).…”

“…The biomization method is similar to the so-called integrated plant record (IPR) analysis, a procedure previously developed for central Europe that assigns paleobotanical remains (leafs, fruits, pollen) to their nearest living relatives and the extant vegetation types they form (Kovar-Eder et al, 2008). This method has recently been used in the Iberian Peninsula together with the coexistence approach, as quoted above (Casas-Gallego et al, 2021). Both biomization and IPR methods also assume community constancy over the Neogene.…”

In the Mediterranean region, the study of fossil pollen has provided a comprehensive spatiotemporal paleoclimatic and paleovegetational picture of the Neogene flora and vegetation. The NW Mediterranean sector is a reference area for the study of vertebrate evolution, especially during the Middle Miocene, but paleofloristic and paleovegetational patterns are much less known, which hinders placing faunal evolution in the appropriate paleoenvironmental context. Here, the existing palynological evidence for this area is reviewed to identify the main knowledge gaps and to devise possible future developments. The few palynological records available have provided quantitative paleotemperature and paleoprecipitation estimates, along with general paleovegetation reconstructions, using the modern-analog (MA) approach. The suitability of this method is discussed here and the use of a complementary method, the fossil community (FC) approach – which has been demonstrated to be useful in other areas and time intervals – is proposed and illustrated using the available raw data. The MA approach is consistent with the available paleoclimatic evidence but special care should be placed on the reliability of overly precise quantitative estimates and the latent danger of circularity when analyzing the biotic responses to climatic changes. The FC approach is considered to be more suitable for reconstructing past communities because it requires less unwarranted assumptions. Additional fieldwork efforts are needed in the search for new pollen records, with an emphasis on more complete ecosystem reconstructions using both floral and faunal evidence.
