Alberta University paleontologists have discovered coin-sized ‘cartoon-eyed’ crab species Callichimaera perplexa through 90-95 million-year-old fossilised remains. “They had what looked like the eyes of a larva, the mouth of a shrimp, claws of a frog crab, and the carapace of a lobster,” researchers said. The crab fossils were discovered in 2005 in the Andes Mountains in Colombia.
