Overview
- The remains were found near Castrillo de la Reina in Burgos province by a team from the Dinosaurier-Museum Salas de los Infantes.
- Individuals measured just over half a meter from snout to tail and would have stood about knee-high on two legs.
- The species lived around 120 million years ago and is described in the peer-reviewed journal Papers in Palaeontology.
- Bone microstructure analyzed under Koen Stein confirmed adulthood in the largest specimen, ruling out a purely juvenile sample.
- Researchers report specialized teeth and a growth-related posture shift, interpreting the animal as built for quick sprints in dense forests.
