摘要:

A new species of fossil wood,Paraphyllanthoxylon alabamense, is described from silicified logs collected in Macon and Elmore counties from the Tuscaloosa Group, Cretaceous, Cenomanian‐Turonian Stage. All of the logs examined from this area have the same general characteristics and are placed in the new species.Paraphyllanthoxylon alabamenseshows many characteristics intermediate between the two previously described species but it is not identical with either of them. This wood is probably not identical with any living type but it resembles certain members of the Anacardiaceae, Buseraceae, Euphorbiaceae, and Sapindaceae. The large size and abundance of logs ofParaphyllanthoxylon alabamensesuggest that it was a dominant Cretaceous forest tree.
