Argentinian geologist Eduardo Olivero became the first scientist to find the remains of a dinosaur in Antarctica in 1986. But digging in frozen ground is not easy, so recovering them took several trips over a decade.

Eduardo had to work with discretion and hide the fossils a couple of times to prevent other scientists from taking away his discovery. It was later proven the dinosaur is a new kind of Ankylosaurus that now carries his name: Antarctopelta oliveroi.

He speaks to Stefania Gozzer about the challenges he faced working below freezing point in Antarctica and the friendly rivalries that rise in such a remote environment.
