In
2013, an expedition led by the Chilean Antarctic Institute (INACH)
discovered fragments of yellowish bones at the bottom of a
hillside close to the major tourist destination Torres del Paine
in Patagonia. This kicked off an almost decade-long
investigation.
"At first, we thought it was from the same group as other South
American hadrosaurs, but as the study progressed, we realized
that it was something unprecedented," said Jhonathan Alarcon,
the main author of the study.
Alarcon said researchers extracted more than 100 pieces and it
was difficult to pull them out without damaging others. After
that, scientists had to make sure the bones belonged to the same
species and check them with existing research to verify that it
was indeed a new species.
"(The) Gonkoken nanoi is not an advanced duck-billed dinosaur,
but rather an older transitional duck-billed lineage: an
evolutionary link to advanced forms," said Alexander Vargas,
another study author.
The extensive research allowed scientists to digitally
reconstruct the skeleton and the team is hoping to 3D print it
to display it to the public.
Gonkoken is a combination of two words from the Aonikenk
language. "Gon" means similar or similar to and "koken" means
wild duck or swan. The indigenous Aonikenk people inhabited
Patagaonia until the end of the 19th century.
While "nanoi" is in recognition of Mario 'nano' Ulloa, a former
ranch keeper who provided the team with logistical support
during the first discoveries, Alarcon said.
