Overview
- The PLOS ONE study catalogs 1,321 trackways at Torotoro National Park’s Carreras Pampa, now described as the largest recorded dinosaur-track site.
- Most impressions are three-toed “ghost tracks” interpreted as theropod in origin, but scarce skeletal fossils limit species-level identifications.
- Investigators documented numerous swim tracks and tail-drag impressions, with the swim marks possibly made by theropods or ancient crocodilians.
- All tracks occur in one sediment layer from an Upper Cretaceous lakeshore, preserving curved paths, pauses, and other moment-to-moment behaviors.
- Researchers characterize the site as an ichnologic concentration and conservation Lagerstätte and emphasize ongoing mapping and protection needs.
