摘要

本文系统地记录了澳大利亚东南部Otway盆地Campanian-Maastrichtian沉积物中丰富多样的类变形科三孔花粉，并与现存变形科花粉进行了比较。化石和现存花粉类型的分离影响了花粉的孔隙特征，并鉴定出6种状态。孔径有胶体、多孔或多孔。Propylipollis Martin & Harris, 1974的孔隙与Grevillioideae亚科和Carnarvonioideae亚科的孔隙一致。Beaupreaidites的胶体，Cookson修正。Martin, 1973, Lewalanipollis gen. nov.的孔隙和Cranwellipollis Martin & Harris, 1974的孔隙分别代表了Proteoideae和persononioideae亚科。Proteacidites Cookson ex Couper, 1953的孔隙分布在Proteoideae亚科和Sphalmioideae亚科。在Otway盆地的化石记录中，三孔体比三孔体、三孔体和双孔体出现得更早;proteproteeous pollen的多样性水平比其他地方报道的要高，这意味着…

Pollen of proteaceous-type from latest Cretaceous sediments, southeastern Australia

Abundant and diverse proteaceous-like triaperturate pollen from Campanian-Maastrichtian sediments in the Otway Basin, southeastern Australia are systematically documented and compared with pollen of extant Proteaceae. Segregation of fossil and extant pollen types has been effected on apertural characters of which six states have been identified. Apertures are colpoid, poroid or porate. Pores of Propylipollis Martin & Harris, 1974 conform with those of subfamilies Grevillioideae and Carnarvonioideae. Colpoids of Beaupreaidites Cookson emend. Martin, 1973, poroids of Lewalanipollis gen. nov., and pores of Cranwellipollis Martin & Harris, 1974 are represented in subfamilies Proteoideae and Persoonioideae. Pores of Proteacidites Cookson ex Couper, 1953 occur in subfamilies Proteoideae and Sphalmioideae. In the Otway Basin fossil record, triporate apertures appear earlier than tricolpoids, triporoids and biporates; and diversity levels of proteaceous pollen are higher than reported from elsewhere implying the ...

期刊介绍： Alcheringa : An Australasian Journal of Palaeontology is the official journal of the Australasian Palaeontologists. Alcheringa covers all aspects of palaeontology and its ramifications into the earth and biological sciences, including: Taxonomy- Biostratigraphy- Micropalaeontology- Vertebrate palaeontology- Palaeobotany- Palynology- Palaeobiology- Palaeoanatomy- Palaeoecology- Biostratinomy- Biogeography- Chronobiology- Biogeochemistry- Palichnology. Review articles are welcome, and may be solicited from time to time. Thematic issues are also possible. Emphasis is placed on high quality and informative illustration, in both line drawings and photographs. Papers of general significance may receive preference over those of more local interest.
