The North American porcupine (Erethizon dorsatum), also known as the Canadian porcupine, is a large quill-covered rodent in the New World porcupine family. It is the second largest rodent in North America after the North American beaver (Castor canadensis). The porcupine is a caviomorph rodent whose ancestors crossed the Atlantic from Africa to Brazil 30 million years ago,[5][6] and then migrated to North America during the Great American Interchange after the Isthmus of Panama rose 3 million years ago.[7]
