10-year-old boy helps discover fossil of dinosaur-era fish
Palaeontologists have discovered a new species of fish after a 10-year-old tourist noticed the shape of a fish in flagstones during a monastery tour in Colombia. The fossil, about 90 million years old, has no modern relatives and is the first "fish lizard" from the Cretaceous period found in tropical South America, said Canada-based researcher Oksana Vernygora.
