Caption: This is a bighorn sheep (Ovis canadensis) skull on Tiburón Island. Skull from bighorn sheep population introduced on Tiburón Island, Gulf of California, in 1975. Radiocarbon dating and ancient DNA analysis from a local cave now show that this introduction unintentionally re-established bighorn sheep that had gone extinct on the island.
