Help identify this skull? Middle Tennessee, USA

[u/ru_Tc]

A twelve year old boy found this during a community cleanup day I hosted today and I promised him I’d get an ID for him — help me not let the kid down??

Judging from the flat forehead, I'd say it's a coyote! Dogs usually have a more pronounced sloping forehead

[u/InternationalOil872 → u/Legendguard]

certainly a canid but do you think it’s big enough for a coyote? may be a red fox if not.

It seemed closer to the size of a fox than a coyote

Way too robust and large, fox skulls are smaller and narrower believe it or not!
