.... A theropod trackmaker is inferred for some of the tridactyl impressions with several indicative of the ichnotaxon Eubrontes . This new site strengthens the inference, originally based on a previously discovered locality near Duntulm Castle (Duntulm Formation) in northern Skye, that sauropods habitually spent...

Graph showing the relationship between the divarication angle and the length to width ratio of the third digit (pIII:wIII) of the dinosaur tracks from the Valtos Sandstone Formation, the Duntulm Formation and the Lealt Shale Formation. The Valtos Sandstone Formation is split into those tracks that were identified as Grallator (small) and those identified as Eubrontes (large). Track 16 from level B at An Corran is shown separately from the tracks of level A. The width of the third digit was measured as the maximum width within the proximal two-thirds of the length of the digit as the digit pads were not clear.

Figure 6. Strontium isotope evolution curve for Middle Jurassic seawater. A belemnite analyzed in this study from Belemnite Sands Member yielded 0.70688. This curve is used to determine 87Sr/86Sr ratio of seawater at time of deposition of Staffin Bay and Duntulm Formations and Kildonnan Member. Marine 87Sr/86Sr ratios are used as reference points for comparing molluskan 87Sr/86Sr ratios from Great Estuarine Group and for paleosalinity calculations based on Sr material balance considerations.
