Lapara Creek

The Lapara Creek Fauna is typical of the Clarendonian Chronofauna (Webb, 1983; Tedford et al., 1987) and includes few endemic forms. Many of the taxa are known from correlative faunas of the Great Plains and some reflect broader distributions into the southwest (Southern Rockies) and eastward to Florida.

A Re-Description of ''Mycterosaurus'' smithae, an Early ...

2016-6-22 · ''Mycterosaurus'' smithae, from the Cisuralian (early Permian) of Colorado, was first described in 1965 as a second species of the genus Mycterosaurus. While the type species of this genus, M. longiceps, has been shown by multiple cladistic analyses to belong to the basal synapsid family Varanopidae, ''M.'' smithae has been largely ignored since its original description.

2016-3-4 · 1 Introduction and Context. Early observations by the Curiosity rover in Gale Crater revealed isolated outcrops of cemented gravel and sand size grains with textures typical of fluvial conglomerates [Williams et al., 2013].These conglomerates occur as local outcrops on a hummocky plain that has a surface mainly covered by a residual lag composed of clasts and sand.

The evolutionary history of dogs in the Americas

2018-7-6 · Dogs have been present in North America for at least 9000 years. To better understand how present-day breeds and populations reflect their introduction to the New World, Ní Leathlobhair et al. sequenced the mitochondrial and nuclear genomes of ancient dogs (see the Perspective by Goodman and Karlsson). The earliest New World dogs were not domesticated from North American wolves but …
