摘要

摘要:在怀俄明中部Hendry Ranch地区的马车床组的Uintan和Duchesnean沉积物中发现了一种新的小型啮齿动物Natrona natronensis，新属和新种，其P4结构与更衍生的环类啮齿动物的M1具有一定的形态学相似性。这个新谱系的其他出现可能来自始新世的德克萨斯州Trans-Pecos和加拿大萨斯喀彻温省的Lac Pelletier。

Paleontology and Geology of the Badwater Creek Area, Central Wyoming. Part 21. Natrona, a New Genus of Rodent, Family Sciuravidae (Mammalia)

ABSTRACT A new small sciuravid rodent, Natrona natronensis, new genus and species, from Uintan and Duchesnean deposits in the Wagon Bed Formation at the Hendry Ranch locality in central Wyoming exhibits some morphological parallelism in the structure of its P4 to the M1 of the more derived cricetid rodents. Other occurrences of this new lineage may be from the Eocene of Trans-Pecos Texas and Lac Pelletier, Saskatchewan, Canada.

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.
