A sauropod tracksite near Fumanya (Berguedà, Catalunya, Spain) was mapped in detail in 1996. Discovered by Viladrich (1986), this is the only known Maastrichtian sauropod tracksite in Europe. The tracks have been strongly affected by strain and erosion. The wide‐gauged, four‐clawed pes trackways are attributed to titanosaurs. Although most trackways indicate single individuals, a few trackways involved multiple individuals, suggesting social behavior.
