Basically, it would seem that the only portions of Castor canadensis seems to be lacking at sight CbGu-5 when collaborating previous excavations, are paws, and therefore, no further conclusions can be drawn from representative body portions. The 1997 assemblage also lacks cut-marks. The only evidence of butchering on Castor canadensis lies in vertebrae hack marks. This implies that instead of small cut marks embedded on the bone surface, the vertebra has been disarticulated with a clean cut, most likely from an axe. There are four positive identifications of muskrat.
Specimens represent the head portions including two left mandibles, and dentition.
Only one fore limb was represented by a left humerus. Since no evidence of cut marks or thermal alterations were found on these specimens, it is most likely that their presence in the assemblage is due to natural phenomena. Canis familiaris or the common domestic dog has also been speculated to have been present during the La Ronde Occuation. Laurentian University excavations of 1996 unearthed the phalange of Canis familiaris. The present assemblage adds further evidence with the recovery of dentition fragments.
