Palaeoclimatic reconstruction for the Late Oligocene La Val fossil site (Estadilla, Huesca, Spain) based on CLAMP and LMA

In this paper, we reconstruct palaeoclimate for the late Oligocene (Chattian) La Val plant assemblage of Spain (NE Iberian Peninsula). Our study employs both CLAMP (Climate Leaf Analysis Multivariate Program) and LMA (Leaf Margin Analysis), the first time these two techniques have been directly comp...

Our study employs both CLAMP (Climate Leaf Analysis Multivariate Program) and LMA (Leaf Margin Analysis), the first time these two techniques have been directly compared, and is based on 25 morphotypes (representing 23 taxa) of woody dicot leaves from a single stratigraphic unit (layer LV6).
