- Comments
- AjGv-VP, Toronto subway: Churcher and Peterson (1982) assign this specimen to a new genus and infer that it was deposited immediately after the drainage of Glacial Lake Iroquois in association with pollen representing a mixed hardwood-conifer forest. Spiess, et al. (1985) regard the specimen as a caribou (Rangifer tarandus).
