RICHARD John Rayner 《Lethaia: An International Journal of Palaeontology and Stratigraphy》1987,20(2):123-127
These are the first known fossil Diptera from sub-Saharan Africa. They are early Upper Cretaceous in age, and were collected from Botswana with fossil angiosperms. They are assigned to the extant family Bibionidae. The association of Diptera and angiosperms at this time in the fossil record suggests that the former played an important part in the evolution of the flower. 相似文献

The following publications on anthropological and closely related topics have been received since the previous list was closed. Only books, monographs, and the initial issues of new journals are listed; space limitations prevent inclusion of subsequent journal issues and of offprints of single articles from journals. No exchanges are conducted, nor can any item be returned. Books that publishers or authors send to the Book Review Editor before or immediately after their publication dates are more likely to be reviewed, and usually will be reviewed sooner, than those he must discover himself. This listing serves to acknowledge receipt of such items, but neither promises nor precludes subsequent publication of reviews. 相似文献
