Last fall most American Toads burrowed below the frost line, digging backwards one to two feet into the ground before beginning their winter hibernation. This spring, as soon as the temperature is consistently above 40°F., they will emerge.
Unfortunately, it seems that the pictured toad emerged too early during one of our warm spells this winter (of which there were many). One can’t know for sure, but it looks as though this is what happened, and without an adequate food supply it died of starvation or froze when the temperature dropped back down. To the left of the desiccated toad is some scat which looks very much like American Toad scat to me.
