Most described Mesozoic ants belong to stem groups that existed only during the Cretaceous period. Previously, the earliest known crown ants were dated to the Turonian (Late Cretaceous, ca. 94-90 million years ago (Ma)) deposits found in the USA, Kazakhstan, and Botswana. However, the recent discovery of an alate male ant in Kachin amber from the earliest Cenomanian (ca. 99 Ma), representing a new genus and species, Antiquiformica alata, , revises the narrative on ant diversification. Antiquiformica can be distinctly differentiated from all known male stem ants by its geniculate antennae with elongated scape, extending far beyond the occipital margin of the head and half the length of the funiculus, as well as its partly reduced forewing venation. Furthermore, the combination of a one-segmented waist with a well- developed node, elongated scape extending beyond the occipital margin, and reduced forewing venation, particularly the completely reduced m-cu and rs-m crossveins and absence of rm and mcu closed cells, firmly places the fossil within the extant subfamily Formicinae. Fourier transform infrared spectroscopy (FTIR) confirmed that the amber containing Antiquiformica alata originated from the Kachin mines in Myanmar. This discovery significantly revises our understanding of the early evolution of Formicinae. The presence of Antiquiformica in Cenomanian amber indicates that the subfamily Formicinae emerged at least by the start of the Late Cretaceous, with crown ants likely originating earlier during the earliest Cretaceous or possibly the Late Jurassic, although paleontological evidence is lacking to support the latter hypothesis.

A NEW CHILOTHERE SKULL FROM HEZHENG,GANSU, CHINA——WITH SPECIAL REFERENCE TO THE CHINESE 'DICERATHERIUM'

引用

Science in China,Ser.B 1988年第4期31卷 493-504页

作者：邱占祥谢俊义阎德发 GANSU museum nat hist LANZHOU PEOPLES R CHINA

In this paper a new chilothere species, Acerorhinus hezhengensis represented by associated skull andlower jaw from Late Miocene deposits of Hezheng, Gansu, is described. The Chinese 'Diceratherium'problem is reviewed and analysed. Systematically, the Chinese 'Diccratherium' has scarcely any direct rela-tion with the true Diceratherium of North america. Heissig’s referral of the Chinese 'Diceratherium' toChilotherium as a subgenus is here disputed. A series of distinctive characters warrant the Chinese 'Di-ceratherium' a generic rank, for which Acerorhinus created by Kretzoi in 1942 is adopted. Acerorhinusshares common apomorphic features exclusively with Chilotherium. They may represent a separate tribein the subfamily Acerotheriinae: Chilotherini.

A fruit of Eucommia has been recovered from the Eocene of Fushun, Liaoning Province. This represents the only confirmed occurrence of fruits of this genus in the paleobotanical record of China. Although Eucommia is endemic to central China today, the genus was more widespread in the Northern Hemisphere during the Tertiary. The fossil speci-

＜正＞ Examination of nucleotide variation at the nuclear RAG-1 locus has proven useful in inferring relationships among passerine birds. Within the passerines, these data support monophyly of the oscines, and of a diverse clade of oscines, previously revealed by the DNA-DNA hybridization studies of Sibley and Ahlquist, named the Passerida. Some relationships within this clade are supported both by the DNA hybridization data and by our
