That looks an awful lot like a Cattle. The leg placement seems just right, and it can't be game, or furs, because it doesn't appear to be a forest. If it is cattle, then think how fast our capital will grow... Even under depotism it will produce 3 food and 1 shield a turn, meaning less turns will be needed to get a larger city. Thus more settlers and workers. Since settlers and workers are necessary early in the game, it is worth the loss of production late in the game. I say use the worker to explore NW, and then move the settler if it is a cattle. If its wheat(unlikely, but not sure) , I don't know... the shield loss this early might be prohibitive...
