"Perhaps the most interesting of the model animals is the one that I personally take to represent a horse. Confirming this identification, Wheeler (1968: 92) observed: "One terracotta, from a late level of Mohenjo-daro, seems to represent a horse, reminding us that a jawbone of a horse is also recorded from the same site, and that the horse was known at a considerably earlier period in Baluchistan.""

"The use of these two objects is as yet uncertain, but I suggest that they were writing-tablets. It would, of course, be difficult to inscribe anything upon their present very rough surfaces but these may once have been covered with some smooth preparation that would allow of writing or numbers being washed off when finished with. In shape these objects are exactly like the large wooden writing-boards that are used at the present day by children in the Punjab and elsewhere."
