The extrabasinal elements in Lower Pennsylvanian floras of the Maritime Provinces, Canada: Description of Adiantites, Pseudadiantites and Rhacopterid…
2021
Adiantites adiantoide s (Lindley and Hutton) Kidston, Pseudadiantites sessilis (Roehl) Gothan and Pseudadiantites rhomboideus (Ettingshausen) comb. nov. are figured and described as well as Rhacopteridium speciosum (Ettingshausen) Hirmer, as part of a revision of lower Pennsylvanian floras of Nova Scotia. These species show a foliar branching structure which is described as "pseudopinnate" as against the fully planated pinnate structure of the Palaeozoic fern and pteridosperm fronds. Their systematic affinity is unknown. A discussion is presented of the genera A diantites, Pseudadiantites, Aneimites , Palaeopteridium , and Triphyllopteris , and the problematic nature of the history of Adian…
New occurrence of the family Hipponicharionidae (Bradoriida, Arthropoda), in the lower and middle Cambrian of the Cadenas Ibéricas, Spain
2004
The bradoriids Hipponicharion aff, hispanicum and Wimanicharion aff. matthewi are reported from the lower and middle Cambrian strata of the Cadenas Ibericas, Spain. The genus Hipponicharion seems to be restricted to the Acadobaltic Province. Wimanicharion has been recorded from Sweden and Canada (Nova Scotia). The new discovery of Wimanicharion in Spain indicates its similar palaeobiogeographical distribution to Hipponicharion.
