Found at entrance to cave, I'd have guessed at rat. The opposite end to the incisor felt soft and flexible like cartilage. Is the gap between the teeth a diastema or just missing teeth? Running through the key I have (even without the skull - although problematic is not quite completely futile) leads me to rat or mouse. At approx. 50mm long I'd then have to go with rat. And for distribution I'd have to take a stab at Rattus rattus.
Possibly gray fox.
