Archosaur specimens collected from the Kilmaluag Formation (Great
Estuarine Group) of Cladach a’Ghlinne, Skye are described. These
comprise crocodylomorph material; a pubis and group of osteoderms with
an associated tooth; a theropod tooth; and a dinosaur limb bone. The
material is regionally important as the Skye assemblage is dominated
by aquatic amphibians and amphibious reptiles with terrestrial taxa
being comparatively rare. The crocodylomorph pubis is referable to an
indeterminate mesoeucrocodylian; the osteoderms and associated tooth
to an indeterminate neosuchian. The Kilmaluag Formation has now
yielded the only associated and articulated terrestrial/freshwater
Middle Jurassic crocodylomorphs from the UK thus far. The theropod
tooth is referable to an indeterminate theropod, and provides the
first body fossil evidence of a small theropod taxon from the
Bathonian of the Hebridean Basin. The dinosaur limb bone is regarded
conservatively as an indeterminate dinosaur although it does possess
possible theropod affinities.
