Araucarioxylon Kraus is a widely known fossil genus generally used for woods similar to that of the extant Araucariaceae. However, since 1905, several researchers have pointed out that this name is a junior nomenclatural synonym and, as such, a nomen illegitimum. At least four generic names are in current use for fossil wood of this type: Agathoxyl...

We present the first anatomical description and taxonomic interpretation of macroscopic charcoal from the Late Miocene of the Staniantsi Coal Basin in western Bulgaria. The charcoal closely resembles the wood genus Taxodioxylon and thus can most likely be assigned to taxodioid Cupressaceae. This group of plants was part of the peat-forming swamp ve...

Abstract Taxodiaceous woods are among the most investigated in Lusatia (Central Europe) as well as in the European Cenozoic. Although these conifer genera have been known for a long time, the use of the generic names is confusing, especially in regard to their relationships to extant taxa. In Lusatia there occur some Taxodioxylon species with affin...

A remarkable fossil assemblage—fifteen 'in situ' stumps standing at their original position—was explored at the opencast lignite mine at Bükkábrány, N Hungary. The stumps occupying an area of about 50 × 100 m have been preserved in Upper Miocene grey sands overlying the lignite seam. The height of the trunks ranges from 2 up to 5.2 m, their perimet...

Mummified foliage, seeds and cones of Glyptostrobus europaeus (Brongniart) Unger (Taxodiaceae, or Cupressaceae s. l.) are very common within muddy sediments embedding large arboreal stumps in several Pliocene localities of northern and central Italy.
