18,000 dinosaur footprints found in Bolivia—here's why it's a big deal

Technology Dec 07, 2025

Scientists have uncovered over 16,600 carnivorous dinosaur footprints at Carreras Pampa in Bolivia, making it the largest dino tracksite ever found.
All tracks are from meat-eaters—no herbivores in sight—and date back to the Late Cretaceous period.

Dinosaurs swimming? Yep, that happened here

Researchers spotted 1,321 continuous trackways along what was once a lakeshore and even found 1,378 swim prints.
That means these theropods weren't just running—they were actually swimming, challenging what we thought about their abilities.

Only predators left their mark—and that's got scientists curious

Every footprint belonged to bipedal carnivores. With no prey tracks around, experts are now debating why only predators gathered here.
Was it a hunting hotspot or maybe just better conditions for preserving certain tracks? The mystery is still up for grabs.
