“Colonisation and early peopling of the Colombian Amazon during the Late Pleistocene and the Early Holocene: New evidence from La Serranía La Lindosa” in Quarterly International by Morcote-Ríos et al., March 2021.
Please be careful about phrases like “has been discovered” which imply recency.
OP, this discovery is from over four years ago. The Live Science article is from December 2020, and the open-access journal article was published March 2021.

Even before that, this is just when researchers were able to have access and time to publish. See my other comment.
