摘要

尼日利亚始新世的新标本获得了一新属和新种Amekicarcinus enigmaticus和一新种Glyphithyreus benensis。在同一沉积物中还发现了一具轴足动物的不确定残骸。尼日利亚的十足类在始新世普遍表现为特提斯或准特提斯分布，而白垩纪还包括大西洋分布。许多尼日利亚十足类属跨越大西洋的K/Pg边界，靠近希克苏鲁伯撞击区。

New Eocene Crabs from Nigeria (Decapoda: Brachyura: Heterotremata)

ABSTRACT New specimens from the Eocene of Nigeria yielded one new genus and species, Amekicarcinus enigmaticus, and the new species Glyphithyreus bendensis. Indeterminate remains of an axiid decapod were also collected from the same deposit. Nigerian decapod occurrences in general display a Tethyan or Paratethyan distribution in the Eocene, whereas Cretaceous occurrences include Atlantic distributions in addition. Many Nigerian decapod genera cross the K/Pg boundary in the Atlantic, proximal to the Chicxulub impact area.

期刊介绍： Annals of Carnegie Museum is a quarterly journal that publishes peer-reviewed short and medium-length original scientific contributions in organismal biology, earth sciences, and anthropology, in 40 by 52.5 pica format (168 by 220 mm or 6-5/8 by 8-5/8 inches). Subject matter must be relevant to Carnegie Museum of Natural History scientific sections or Powdermill Nature Reserve (PNR), preferably with connection to the Carnegie collection and/or personnel. Carnegie Museum staff and research associates receive publication priority, but others are encouraged to submit papers, especially those manuscripts explicitly based on the Carnegie collection.
