Nature 458:1021-4. 2009..The discovery suggests that the evolution of pinnipeds included a freshwater transitional phase, and may support the hypothesis that the Arctic was an early centre of pinniped evolution...
- Re-evaluation of Sinocastor (Rodentia: Castoridae) with implications on the origin of modern beaversNatalia Rybczynski
Earth Sciences, Canadian Museum of Nature, Ottawa, Canada
PLoS ONE 5:e13990. 2010..We conclude that Sinocastor is a valid genus. Given the prevalence of apparently primitive traits, Sinocastor might be a near relative of the lineage that gave rise to Castor, implying a possible Asiatic origin for Castor...
