Abelichnus astigarrae

Abelichnus astigarrae is an ichnotaxon — a dinosaur trackway rather than a body fossil — from the Early Cretaceous of Argentina. The tracks are attributed to an abelisaurid theropod and were discovered in La Rioja Province. Ichnotaxa like Abelichnus help reconstruct dinosaur behavior and locomotion from trace fossils.

The final age of dinosaurs, featuring iconic species like Tyrannosaurus rex, Triceratops, and Velociraptor. Dinosaurs reached their peak diversity before the catastrophic asteroid impact at the Chicxulub crater ended the Mesozoic Era.
