MANCHESTER, Steven R.; CALVILLO-CANADELL, Laura  y  CEVALLOS-FERRIZ, Sergio R.S.. Assembling extinct plants from their isolated parts. Bol. Soc. Geol. Mex [online]. 2014, vol.66, n.1, pp.53-63. ISSN 1405-3322.

Fossils have always been an intriguing and spectacular source of information for naturalists who discuss how life and diversity came about. In plants, it is difficult to find in the fossil record all organs or plant parts in connection to each other. Thus, many angiosperms are sketched as undefined entities that somehow resemble an extant relative. Nevertheless, several examples of whole plant reconstructions based on extensive collection of fossil parts have been published through the years. Two methods have been used to reconstruct fossil plants: 1) Through organic connections among the different organs, and 2) concurrent location of fossil parts (seed, leaves, flowers, etc.) in the same locality and across localities. In the latter case, the argument can be strengthened by similarities of epidermal anatomy. The association of organs gives a more complete picture of fossils plants and it can help to make better taxonomic inferences, as they provide a morphological tool about plants that grew in the past. This information may as well be used in other areas, such as biogeography or phylogenetics.
