Piatnitzkysaurus floresi
Piatnitzkysaurus floresiPiatnitzkysaurus floresi was an agile, medium-sized predator that patrolled the lakeshores and river floodplains of Jurassic Patagonia. Its lightly built skull bore blade-like serrated teeth, and its proportionally robust forelimbs carried curved talons well suited for gripping swift prey. As one of the earliest known basal tetanuran theropods, its anatomy provides critical insights into the initial evolutionary radiation of large predatory dinosaurs across southern Gondwana.
