Repository: CT data and reconstructions of various published flora from the Eocene of Anjou, North Western France. Publication: Christine Strullu-Derrien, Alan R. T. Spencer, Paul Kenrick, Walter S. Judd, Dario De Franceschi & Steven R. Manchester (2022) Revisions to the Eocene carpoflora of Anjou, western France, with new data from X-ray tomography, Botany Letters, DOI: 10.1080/23818107.2022.2101518 Abstract: Selected fruits and seeds preserved as molds and casts in sediments from the Anjou flora of Maine-et-Loire have been reexamined with the aid of X-ray tomography. Virtual casts and surface renderings from micro-CT scanning data reveal external and internal morphological characters that were not visible by standard reflected light microscopy. Application of this methodology leads to a revision of the fruit formerly treated as Juglandicarya. It is a 5-valved capsule of likely sapindalean affinity, and is placed in Vaudoisia gruetii (Vaudois- Miéja) gen. et. comb. nov. A seed with the characteristic rumination of Anonaspermum is also recognized for the first time, as are capsular fruits of Ericaceae. We note that many disseminules are hidden from optical viewing because they are buried within the hand samples. A more extensive micro-CT scan investigation of more samples, including those showing only fossil leaf impressions at the surface, may be expected to yield a wealth of new information on this classic flora.
