Acrostichum is considered today an opportunistic fern in disturbed areas, which indicates the first stages of colonisation such zones. However, fossil record, appears related to fluvio-lacustrine environments, freshwater marshes and mangrove deposits. We report here for time evidence that reveals a pioneering behaviour this perturbed communities Europe, corroborates previous assumptions about paleobiology Acrostichum. Plant remains were collected from Chattian (late Oligocene) La Val site...
This paper reports a previously unknown leaf-flora from the Upper Oligocene/Lower Miocene of Ebro Basin, NE Spain, period with relatively poor vascular-plant fossil record in Southern Europe. The presence Acrostichum sp. is also important. fern extremely significant point view palaeoecology and depositional environment. macroflora appears to yield sufficient morphological characteristics be identified at genus level, sometimes species although cuticles are not preserved. article presents...
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), first time these two techniques have been directly compared, is based on 25 morphotypes (representing 23 taxa) woody dicot leaves from a single stratigraphic unit (layer LV6). Both methods provided similar result. Although standard deviation higher than...
A new well-preserved spore assemblage has been discovered from the Lower Devonian Nogueras Formation of Mezquita de Loscos (Teruel Province, north-eastern Spain). The palynoflora includes 34 species belonging to 20 genera, among which 14 are for locality, e.g. Apiculiretusispora, Brochotriletes, Cirratriradites, Iberoespora, Knoxisporites and Verrucosisporites. is mainly composed trilete spores, while tripapillate monolete forms also observed. An early Pragian age suggested fossil site....
AbstractRecent fieldwork has uncovered three new localities from the Lower Devonian of Mezquita de Loscos (Teruel Province, Spain) with further plant mega-fossils and first record micro-fossils. Such remains have been interpreted as belonging to a basal euphyllophyte, Taeniocrada-like stems, Hostinella genus paired sporangia. Fourteen spore taxa were recovered, including Ambitisporites, Aneurospora, Brochotriletes, Chelinospora, Emphanisporites, Gneudnaspora Retusotriletres, among others....
Fossil fruits pertaining to the mangrove palm genus Nypa Steck, (Arecaceae, Arecales) were collected from a new plant-bearing assemblage in Arguis Formation (Fm.), northeastern Ebro Basin (Arguis, Huesca Province, Spain). This formation is Bartonian early Priabonian age and comprises pro-delta carbonate platform deposits. The consists of nine specimens fossil one monocotyledon leaf fragment. Over half these are nearly-complete (i.e. with preserved mesocarps) while other represent endocarps....
The Late Miocene palaeofloras of the La Cerdanya Basin represent a unique look into Pyrenean forested areas Iberian Peninsula at time when European warm and humid climate was experiencing progressive cooling aridification. Macrofossils (leaves, seeds, fruits cones) miospores from several outcrops revealed composition abundances different plant species present in area during Tortonian early Messinian geological stages (ca. 11.1–5.7 Ma). These fossils were found sediment deposits an ancient...
The early Miocene (Burdigalian) macroflora of the Els Cardscolers site (Majorca Island, Balearic Islands province, Spain) is studied here from a palaeoecological and taxonomical perspective. study shows presence palaeotropical flora with thermophilic hydrophilic elements characteristic coastal wetland environment, formed by monocotyledons, Lygodium gaudinii, palms (Sabalites sp.), predominance shrubs Myrica lignitum accessory such as Berberis kymeana, Engelhardia orsbergensis, Ziziphus...
