Woodcutting behavior in beavers (Castoridae
, Rodentia): Estimating ecological performance in a modern and a fossil taxon.
Meaning "ancient beaver" (Castoridae
is the family that includes beavers), the several known species of Palaeocastor most likely looked like a cross between a modern North American beaver and a gopher and lived only in what is now the American Midwest.
The North American beaver, Castor canadensis Kuhl, 1820 (Rodentia, Castoridae
) was introduced to the main island of the Tierra del Fuego Archipelago (TDF, from now on) in 1946, and by the 2000s, beavers were estimated to impact 20-40% of the stream length of the island (Anderson et al., 2014).

Since all the insectivores and some rodent families (in our case Sciuridae, Castoridae
, Gliridae, Eomyidae) have premolars and others do not (muroid rodents), this results in an over-representation of the former taxa.
