Researchers at the Institut Català de Paleontologia Miquel Crusafont (ICP, Spain), the universities of Zaragoza and Autonomous of Barcelona (Spain) in collaboration with the University of Manchester (UK) and University of Liverpool (UK) have just published in the journal PLOS ONE. Their study of trackways confirms that the titanosaur sauropod dinosaurs that lived in Fumanya (Catalonia, Spain) during the Late Cretaceous walked in the same way, independently of their body size.
Walking just like its giant parent, a sauropod plays 'catch-up' moving just like an adult! |
Titanosaurs were a group of sauropod dinosaurs that had a characteristic arrangement of the femur and pelvic girdle that is reflected in the trackways that have been preserved in the fossil track record. Their gait was wide and the footprints left yield a characteristic ‘wide-gauge’ trackway.

Fumanya, a unique dinosaur site
The Fumanya sites of Fígols and Vallcebre, were declared a Site of National Cultural Interest in 2005. The paleontological site includes the ancient open-cast coal mines in Fumanya Sud, Mina Esquirol, Fumanya Nord and Tumí. On the site, which covers an area of more than 38,000 square meters, more than 3000 dinosaur footprints have been have been found and fossil remains of eggs and bones have been identified, together with tree trunks and leaves from different types of palms. It is considered to be one of the most important sites in Europe for fossil remains of dinosaurs from the Late Cretaceous.

Fumanya, a unique dinosaur site
The Fumanya sites of Fígols and Vallcebre, is for me one of the best examples of Titanosaur trakway surface in the whole of Europe, if not the world. The paleontological site includes the ancient open-cast coal mines in Fumanya Sud, Mina Esquirol, Fumanya Nord and Tumí which were the reason behind in the discovery of the track-bearing horizons by a local school teacher. When you have over 38,000 square meters of exposure and more than 3000 dinosaur tracks...LiDAR is the only way to record, measure and analyse such a vast site. The Manchester team has been working with the ICP team on this site for nearly seven years now and we all know there are many more tracks and trails to be teased from this ancient surface using the light fantastic of LiDAR!
