Stratigraphy: Palaeocene (Thanetian) [see Crawley (2001: 23) for the correction of the initially erroneous Cretaceous (Aptian) age].

Etymology: by superficial likeness to the woods of extant Alnus Mill.

The fossil-genus Cantia Stopes was described on the basis of fossil woods from the erroneously thought Upper Cretaceous (Aptian) sediments of England; Crawley (2001) presented the solid new evidence that these fossil remains come from the younger, Palaeocene (Thanetian) sediments. However, the generic name is a later illegitimate (para)homonym of fossil algal genus Kantia Pia (1912) of the family Dasycladaceae . Thus, a new replacement name for the fossil wood generic name related to extant genus Alnus L. is necessary and here proposed— Paralnoxylon nom. nov.
