Wood identification is a common task for many palaeobotanists. The production of this secondary tissue began during the Devonian and evolved independently in several major lineages of vascular plants since then. Wood composition and toughness usually ensure its fossilization, in many cases without major deformation. Numerous atlases or publications dedicated to specific areas (Détienne & Jacquet 2000, Schweingruber 1990) or systematic groups (Metcalfe & Chalk 1950; Illic 1991; Klaassen 1999; Liang & Baas 1991) for extant and fossil taxa exist to facilitate identifications. The IAWA community also formatted two lists of the main wood anatomical characters suitable for wood identification (IAWA committee 1989, IAWA committee 2004). The latest advance, approximately ten years ago, was the building of the Insidewood database (Insidewood 2004, Wheeler 2011), which allows online identification for extant and fossil hardwood. Nevertheless, an important part of the fossil wood found in sediments is softwood. Our ABIeS project aims to build a knowledge database dedicated to these extant and fossil species which produce homogenous wood, in order to provide a support for identification of fossil softwoods. The beginning of this important project was dedicated to the development of the architecture of the database with the Xper3 online plateform (Ung et al. 2010) and the inclusion of 101 characters. We followed Phillips (1949) and the IAWA nomenclature but also added numerous quantitative features. For the moment, 50 modern species (i.e. 27 genera among the 75 genera of conifer known) represented in the xylarium of the “Muséum national d’Histoire naturelle” in Paris and 70 fossil species from the Boureau collection of the “Université Pierre et Marie Currie” are described in the knowledge base.
