Young tourist helps Edmonton researchers in discovery of rare Colombian fish fossil

Edmonton paleontologists are crediting a keen-eyed tourist for spotting a never-before-seen fish fossilin flagstones outside a Colombian monastery.

The perfectly-preserved "lizard fish"specimen is an estimated 90 million years oldand has no modern relatives. The extremely rare specimen is the first fossil of its kind to ever be found in South America.

"This fossil was one of those serendipitous, unexpected findings," said paleontologist Javier Luque, a PhDcandidate atthe University of Alberta's biological sciences departmentand co-author of theresearch paperon the find.

'Once in a lifetime discovery'

"It was kind of a once-in-a-lifetime discovery, in many ways."

The discovery was made in 2015 atthe Monastery of La Candelaria by a young boywho spotted the outline of a fish in one of the flagstones outside the 17th-century building.

Curious about the strange rock, the boy snapped a photo and shared it with staff at Centro de Investigaciones Paleontologicas, a museum in nearby Rquira, Boyaca. Workers there recognized it as a fossil right away and shared the discovery with the University of Alberta.

The flagstone had been part of the busy pathway for more than 15 years, said Luque.

"A kid was just walking around saw what he thought was a fish and sure enough, he took a photo with the inquiring mind of a child," Luque said.

"It was a fossil fish, perfectly preserved in two dimensions, just laying down, weathering as people were walking on top of it for so many years."

'Shocking tosee'

The museum and the university often partner on fossil finds in the area, said Luque.

After getting the call, a team of U of Aresearchers joined the local paleontologists in retracing the boy's steps to locate and lift the stone for further examination.

Researchers were able to trace the origins of the fossil-bearing flagstoneto a nearby abandoned quarry from where locals extracted slabs for construction several years ago.

The research paper on the fossilwas recently published in theJournal of Systematic Paleontology. It was co-authored byOksanaVernygora, a fellowPhDcandidate at the U of A led the research with assistance from her supervisor, andAllison Murray, a professor of biological sciences.

The rocks date from the Late Cretaceous period, and were deposited at a time when most of the northern Andes was underwater, which accounts for a rich record of marine life in the heart of the Andes mountains.

"It's an entirely new group of fossil fish from the Cretaceous period in South America," Luquesaid.

The fossil is that of a deepwater fish which would have thrived in fast-flowing waters.

It has been named Candelarhynchus padillai, which combines 'Candelaria,' the name of the monastery where the fossil was discovered, and the Greek word for nose 'rhynchos,'due to its peculiar long and slender needle-like face.

And while the fossil's backstory has largely been explained, the fish tale has one moremystery.

Researchers lost touch with theboy whofound the fossil. They have only his name.

They are hoping, with the recent publication of theresearch, the boy might eventually come forward, so they can give him proper credit.

"We certainly will make sure we properly acknowledge this discovery," Luquesaid. "It was the keen eye of a young kid that was able to recognize the shape of a fossil that we were not able to see for so many years.
