From back in late February: a dead muntjac deer, Muntiacus reevesi. It was in woodland, well away from any road, so I can only assume it was killed by a dog.
This was actually the first of two dead muntjacs that I came across on that day. The second was beside the Warren (a road) and had probably been hit by a car.
By early April all that was left was a few tufts of fur and the skull:
