A reappraisal of Lignier's Mesozoic fossil wood collection: Ages, nomenclature and taxonomy

Abstract : In 1907 the French palaeobotanist Octave Lignier published a study of Jurassic fossil wood that was to become a seminal palaeoxylological work. Although the names he established were often used or recombined and his con- tribution is still often quoted today, the original material was never re-studied, except for one of the ␣fteen orig- inally published samples. This material was only recently been rediscovered, after it was thought to be lost since the 1980s. Here we make use of this opportunity to re-evaluate stratigraphical attributions and ages of Lignier's original samples, to review their nomenclatural status and discuss their taxonomical assignment. Three new combinations are introduced: (Agathoxylon tranchantii (Lignier) comb. nov., Baieroxylon divesence (Lignier ex Seward) comb. nov., Brachyoxylon blevillense (Lignier) comb. nov.), and a new species (Agathoxylon crasseradiatum sp. nov.) is published based on Lignier's material. Baieroxylon divesence is anatomically closely re- lated to modern ginkgo and hence an interesting milestone is the little documented history of Ginkgoales wood.
