Identifications are best achieved through the direct inspection of reference material. Most substantial reference collections are held at prestigious universities in Europe or the United States of America which can restrict access for researchers trying to advance palynology in less developed countries. Digital imaging and fast spreading access to the internet means that it is now possible to produce and disseminate high quality images from pollen reference collections. In this paper we contribute to this growing body of work by presenting images of 364 pollen taxa from West Tropical Africa both as printed plates with a key, and within an associated online searchable database. © 2013 Elsevier B.V.

Introduction The accurate identification of fossil pollen and spores underpins our ability to reconstruct past vegetation and subsequently infer variation in the Earth's system. Palaeo-palynology can provide, among other things, evidence for past changes in climate (e.g. Overpeck et al., 1990; Davis and Shaw, 2001), biome (e.g. Jolly et al., 1998; Tarasov et al., 1998; Williams et al., 2004) and biodiversity (e.g. Rull, 1987; Brown, 1999; Odgaard, 1999) across the geological record. At one extreme the incredible resilience of pollen/spore chemistry (sporopollenin) allows palynology to provide evidence for the evolution of plants on timescales of millions of years (e.g. Crane et al., 1995; Wikström et al., 2001). Whilst at the other, the influence of human activity upon plants allows the actions of people within the landscape to be traced in the recent past (10–100s of years ago) (e.g. Brugam, 1978; Piperno and Flannery, 2001). The integrity of the information supplied by palynologists to all these areas is reliant on consistent typing or, where possible, identification of the specimens found in the fossil record. Since its inception morphological identification of pollen grains has been standard practice through comparison with modern material (von Post, 1916, reprinted 1967). Subsequently numerous atlases for pollen and spore identification have been produced from across the globe, including: (Faegri and Iversen, 1989; Moore et al., 1991; Roubik and Moreno, 1991; Colinvaux et al., 1999; Reille, 1999; Beug, 2004). The proliferation of pollen/spore atlases has facilitated the expansion of the field of palynology and helped with international standardization of identifications. In addition, as computing power has developed, there has been an increase in the ⁎ Corresponding author. Tel.: +44 190 865 5147; fax: +44 190 865 5151.

However, geographical coverage and access to images for pollen identification remains patchy. The most substantial atlases for African pollen and spore identification are: (i) in print (Reille, 1998, 1999), and (ii) online the African pollen database (Lezine, 2005). Both contain thousands of images of species within hundreds of families, and therefore provide good general coverage of taxa likely to be found in the fossil record. In addition, pollen/spore atlases for specific regions have also been produced, e.g. East Africa (Riollet and Bonnefille, 1976), as well as for individual countries: (i) Chad (Maley, 1970), (ii) Ethiopia (Bonnefille, 1971a,b), (iii) Ivory Coast (Ybert, 1979), (iv) Nigeria (Sowunmi, 1973, 1995), (v) South Africa (van Zinderen Bakker, 1953, 1956; van Zinderen Bakker and Coetzee, 1959; Scott, 1982), and (vi) Sudan (El Ghazali, 1993). In this paper we contribute to this body of knowledge by presenting c. 3000 images and identification keys for 364 pollen and spore taxa commonly found in tropical West Africa. 2. Materials and methods 2.1. Selection of pollen and spore taxa Taxa were selected for inclusion within this tropical West African pollen atlas based upon two criteria: (i) they had been previously identified within fossil records obtained from terrestrial and marine settings within the region (Maley and Livingstone, 1983; Talbot et al., 1984; Lezine and Vergnaud-Grazzini, 1993; Elenga et al., 1994; Frédoux, 1994; Leroy and Dupont, 1994; Dupont et al., 2000), and/or (ii) they had been identified as significant in the regional flora (Hall and Swaine, 1981). 2 W.D. Gosling et al. / Review of Palaeobotany and Palynology 199 (2013) 1–135 (continued) Table 1 (continued) 2.2. Organisation and presentation of images Images are presented on 129 plates showing both polar and equatorial views of the grain where it was possible to obtain images. Plates are organised by pollen morphology to allow ease of reference when examining fossil pollen material; following (Beug, 2004). The paper is accompanied by a searchable online database which integrates the images presented here with the c. 6000 images of N1000 taxa from the Neotropical Pollen database (Bush and Weng, 2007). To access a Freeware version of the complete revised Tropical Pollen Database download and unpack as appropriate the file TopicalPollenDB2013.zip file from cepsar-ftp.open.ac.uk/TropicalPollenDatabase. Please note due to the high number of pictures the file is large (2.77 GB) and an Apple Macintosh computer running Mac OS X 10.6 or higher is required to run the software. We hope that the combination of our images with those of Bush and Weng (2007) within a freeware format online will promote further expansion by other research groups which will lead to the eventual development of a comprehensive pan-tropical searchable online pollen and spore identification tool. 2.3. Provenance of specimens and image capture Images and descriptions of all pollen and spores were obtained from the reference collection of c. 30,000 specimens housed within the Department of Biology at Duke University which has been collected and curated by DAL. Reference material was sourced from herbaria and laboratories around the globe; full details for individual specimens can be found on the accompanying online database. Images were obtained using QCapture software (v. 3.1.1) with a QImaging Micropublisher 3.3 RTV camera mounted on a Nikon Eclipse 50i microscope. All images were taken through a Nikon Plan Fluor 40x/0.75 DIC M/N2 objective. 3. Terminology Terminology follows Punt et al. (2007). 4. Nomenclature Taxanomic nomenclature follows conventions of Beug (2004). To find images for a specific botanical Family or Species please use Table 1.
