This lizard may have suffered an injury to its tail that did not cause the tail to break off. Instead, parts of the tail grew back in the chaotic mess you see above. (I thought it might be something attached to the tail, but I was assured it was part of the tail.)

(This lizard is from a range of intergradation between S. z. rufidorsum and S. z. monserratensis [Grismer, 2001, pattern classes] so the subspecies is not known. Note that it does have a bit of red on the back below the head.)
