THE STORY BEHIND THE SATIRE · Atacama Desert, Chile · Oct 11, 2026

A nine-million-year-old capybara-relative tooth points to wetlands in today's Atacama Desert

What happened

The New Indian Express reported on October 11 that researchers had identified a roughly nine-million-year-old molar from Chile's Bahía Inglesa Formation as belonging to Cardiatherium, an extinct water-dependent relative of modern capybaras. The peer-reviewed study, published September 5, places the animal in late-Miocene coastal northern Chile, where the same deposits and earlier work also preserve freshwater fish, crocodiles and plant evidence.

Why it matters

One tooth does not prove the entire Atacama was lush, but it gives a minimum ecological fact: a large semiaquatic herbivore reached a place that required usable freshwater and wetland vegetation. Combined with the other fossils and plant microremains, the find strengthens a more varied account of when and where hyperaridity developed and suggests a coastal dispersal route across South America.

The Blappos angle

One Tooth. Whole Wetland. Paleontology found one molar and reopened the desert's plumbing history. The wetland inside the tooth is an explicit imaginative metaphor; the animal's color, pose and exact habitat scene are not preserved by the fossil.
