Brazilian researchers have discovered a 237-million-year-old reptile fossil, **Gondwanax paraisensi**, potentially linked to the evolution of dinosaurs. This small, dog-sized silesaurid reveals unique anatomical features, including three sacral vertebrae, suggesting diverse locomotor strategies. Found in Paraiso do Sul, Brazil, this species enhances our understanding of bird-line archosaurs. Published in *Gondwana Research*, the study highlights the significance of silesaurids in exploring the origins of early dinosaurs during the Triassic period.
