"Rare Florida Fossil Sheds Light on Evolutionary Puzzle"
A rare porcupine fossil found in Florida has resolved a long-standing evolutionary mystery about the origins of North American porcupines. The fossil, belonging to the extinct species Erethizon poyeri, suggests that the Erethizon genus originated in South America and migrated northward around 3-4 million years ago. This discovery reconciles previous conflicting evidence and provides new insights into the evolutionary history and ecological adaptations of these animals.
