A Titanosaurid megatracksite from Fumanya (Maastrichtian, Eastern Pyrenees): preliminary study

The Fumanya megatracksite, 20 km north of Berga (Eastern and Southern Pyrenees), is the first known locality which shows titanosaurid footprints. It is the largest known sauropod trackways site from the Late Cretaceous in Europe. Hundreds of footprints are organised in tenth of trackways on a main track level which can be followed on several kilometres. Another level yielded the footprints of a juvenile. From a preliminary study, one can notice that titanosaurids had four foot daws. Most of the animals apparently walked alone. A few twinned trackways indicate that some titanosaurids moved together, but no «herd» has been discovere
