Paleontologists from the University of Alberta have discovered a never-before-seen species of fish in Colombia, with help from a young and curious tourist.

The fossil, Candelarhynchus padillai, is about 90 million years old and has no modern relatives, explained Oksana Vernygora, a PhD student in the Department of Biological Sciences and lead author on the study.

“A kid was walking into the Monastery of La Candelaria during a tour when he noticed the shape of a fish in a flagstone on the ground,” explained Javier Luque, a PhD candidate and co-author on the study. “He took a photo and, a few days later, showed it to staff at the Centro de Investigaciones Paleontologicas, a local museum with whom we collaborate to protect and study fossil findings from the region.”

Staff at the centre recognized the image as a fossil fish righ...
