Summary The Cretaceous fossil record of amber provides a variety of evidence that is essential for greater understanding of early pollination strategies. Here, we describe four pieces of ca. 99-million-year-old (early Cenomanian) Myanmar amber from Kachin containing four closely related genera of short-winged flower beetles (Coleoptera: Kateretidae) associated with abundant pollen grains identified as three distinct palynomorphotypes of the gymnosperm Cycadopites and Praenymphaeapollenites cenom...

Abstract Phylogenetic diversity reflects both community assembly and evolutionary diversification processes. Communities with low phylogenetic diversity might be the outcome of environmental filters favouring the occurrence and/or the diversification of lineages from particular clades. This rationale applies for regional assemblages. Here we propose to integrate phylogenetic diversity into paleobotanical studies aimed to reconstruct temporal shifts in plant assemblages in the past. To do so we f...

Abstract A palynological study of the Upper Cretaceous vertebrate site of Chera (Valencia, Spain) has been carried out. The occurrence of diversified Normapolles including various species of Vancampopollenites, Papillopollis and Pseudoromeinipollenites suggest a late Campanian–?early Maachtrichtian age. The palynological assemblages suggest an azonal vegetation involving peat-mosses, sedges and palms colonizing wetlands with ephemeral or semi-permanent pools and lakes. The abundant and diverse N...

Abstract Desert coasts in plate margins contain one of the most variable sedimentary records in terms of facies and stacking patterns. Reliefs in these basins together with massif palaeogeography and palaeotopography strongly control the spatial distribution of facies belts and complex lateral facies changes between very different coeval sub-environments, leading to mixtures of sedimentary particles with variable composition. Palaeotopography and palaeogeography also control the distribution of ...

Angiosperms and their insect pollinators form a foundational symbiosis, evidence for which from the Cretaceous is mostly indirect, based on fossils of insect taxa that today are anthophilous, and of fossil insects and flowers that have apparent anthophilous and entomophilous specializations, respectively. We present exceptional direct evidence preserved in mid-Cretaceous Burmese amber, 100 mya, for feeding on pollen in the eudicot genus Tricolporoidites by a basal new aculeate wasp, Prosphex ant...

Abstract A palynological analysis of 45 samples from six mid-Cretaceous amber-bearing outcrops from Charentes has been carried out. A total of 227 taxa have been recorded in the studied palynofloras. Palynological data support earlier evidence and indicate an early Cenomanian age for the assemblages. The heterogeneous compositions of the palynofloral assemblages indicate the existence of different coastal depositional settings with a variable but usually weak marine influence. The local vegetati...

Abstract The Early Pleistocene deposits of the Iberian Peninsula provided some of the oldest hominin fossil sites of Western Europe. Evidence also shows that early Homo thrived in the Mediterranean peninsulas during the Early Pleistocene ‘interglacial’ phases. To assess the role of climatic conditions on early human environments, the present work features a quantitative palaeoclimatic analysis for a number of Early Pleistocene macroflora and pollen assemblages located at different geographical l...
