New #fossils from #Patagonia may rewrite the history of duck-billed dinosaurs https://www.sciencenews.org/article/fossils-patagonia-duck-billed-dinosaurs

Relict duck-billed #dinosaurs survived into the last age of the dinosaurs in #subantarctic #Chile https://www.science.org/doi/10.1126/sciadv.adg2456

"#Gonkoken appears to be part of an older, less specialized lineage that diverged from other #DuckBilledDinosaurs around 91 million years ago, before the first #hadrosaurids evolved"
