What's happened
Researchers documented 16,600 theropod dinosaur footprints in Bolivia's Toro Toro park, the highest recorded globally. The footprints, dating over 60 million years, include evidence of swimming and herd behavior. Human activity has threatened these traces, but ongoing research continues to uncover insights into dinosaur life at the end of the Cretaceous.
What's behind the headline?
The discovery of 16,600 footprints in Toro Toro significantly expands our understanding of theropod dinosaurs' behavior and distribution. The footprints' excellent preservation and variety indicate herd movement, swimming attempts, and possibly migration patterns. This site offers a rare window into the daily lives of dinosaurs at the end of the Cretaceous, contrasting with fossil-rich sites elsewhere. The threats from human activity highlight the importance of protecting such paleontological treasures. The absence of skeletal remains suggests the site was more of a transit route than a nesting ground, emphasizing the importance of footprints in revealing behaviors that bones cannot. This find will likely lead to further exploration and understanding of dinosaur ecology and extinction dynamics.
What the papers say
The Independent reports that the site holds the highest number of theropod footprints ever recorded, emphasizing its global significance. The NY Post highlights the meticulous six-year documentation effort by paleontologists from Loma Linda University, noting the excellent preservation of the tracks and their implications for understanding dinosaur behavior. Both sources underscore the threats posed by human activity, such as farming and construction, which have endangered parts of the site. The Independent also notes the absence of bones, suggesting the area was a migratory corridor rather than a habitat, while the NY Post discusses the potential for future discoveries and ongoing research. The contrasting perspectives mainly revolve around the significance of the site and the threats it faces, with The Independent emphasizing its record-breaking nature and The NY Post focusing on the research process and preservation challenges.
How we got here
The Toro Toro site in Bolivia was first identified in the 1960s, with initial discoveries of dinosaur footprints. Recent studies by a team from California’s Loma Linda University, published in PLOS One, have now documented a record number of footprints, revealing detailed behaviors of theropod dinosaurs. The site’s preservation has been threatened by local farming, quarrying, and road construction, which have damaged some areas. The absence of bones contrasts with other sites, suggesting dinosaurs may have used the area as a coastal corridor rather than a habitat.
