Data from: A new Middle Jurassic lagoon margin assemblage of theropod and sauropod dinosaur trackways from the Isle of Skye, Scotland

Although globally scarce, Middle Jurassic dinosaur tracks are known from
the Isle of Skye, Scotland, and help indicate the palaeoenvironmental
preferences and behaviour of major dinosaur clades. Here, we report an
extensive new tracksite from Skye: 131 in-situ dinosaur tracks at Prince
Charles’s Point on the Trotternish Peninsula. The tracks occur in multiple
horizons of rippled sandstones of the Late Bathonian aged Kilmaluag
Formation, part of the Great Estuarine Group, which formed in a locally,
shallowly submerged marginal lagoon. We assign these tracks to two
morphotypes, further divided into four morphotype subgroups, most likely
representing large megalosaurid theropods, and sauropods that are either
non-neosauropods or basal neosauropods. The trackways, although relatively
short, evidence time-averaged milling behaviour, as observed at other
tracksites in the Great Estuarine Group. The presence of sequential manus
and pes sauropod tracks amends their previous identification by geologists
as fish resting burrows, raising the potential that other such structures
locally and globally may in fact be dinosaur tracks, and emphasises the
predominant occurrence of sauropods in lagoonal palaeoenvironments in the
Great Estuarine Group. At Prince Charles’s Point, however, unlike
previously described lagoonal assemblages, large theropod trackmakers are
more abundant than sauropods.
