Gymnosperm trees from the Permian of Antarctica: An anatomically preserved trunk of Kaokoxylon sp
ACL-12-13 International audience Anatomicallypreservedgymnosperm axes are relatively abundant in Permian localities of Antarctica, but their anatomy has rarely been studied in detail, which limits comparison with other Gondwanan morphotaxa. Here we describe a silicified trunk collected from the Uppe...
