Giant Platypus Found, Shakes Up Evolutionary Tree
What's cooler than a venomous, duck-billed mammal that lays eggs? A giant one—and that's just what researchers have found.
A newly discovered species of three-foot-long (one-meter-long) platypus, dubbed Obdurodon tharalkooschild, swam through freshwater pools in Australian forests about 5 to 15 million years ago, according to a new study. That's a much bigger critter than a modern-day platypus, which at 15 inches (38 centimeters) long is about the size of a small domestic cat.
