Arcovenator escotae Abstract:(Paper: www.sciencedirect.com/science/article/pii/S075339691300089X?cc=y)"The Abelisauridae are a family of mainly Cretaceous theropod dinosaurs with a wide distribution across the Gondwanan land masses. Although their presence in Europe was reported twenty-five years ago, it has often been considered as controversial largely because of the incompleteness of the available specimens. We report here the discovery of well-preserved abelisaurid material, including a highly diagnostic braincase, at a Late Cretaceous (late Campanian) locality in the Aix-en-Provence Basin, near the eponym city in south-eastern France. A new abelisaurid taxon is erected, Arcovenator escotae gen. nov., sp. nov., on the basis of cranial and postcranial material. A phylogenetic analysis reveals that the new Abelisauridae from Provence is more closely related to taxa from India and Madagascar than to South American forms. Moreover, Genusaurus, Tarascosaurus and the previous Late Cretaceous discoveries are identified as basal abelisaurids. Contrary to previously proposed palaeobiogeographical models of abelisaurid evolution, the presence of the new taxon in Europe suggests that Europe and Africa may have played a major role in abelisaurid dispersal, which apparently involved crossing marine barriers."

a new abelisaurid found in the northern hemisphere, and is seemingly closely related to majungasaurus.

a new abelisaurid found in the northern hemisphere, and is seemingly closely related to majungasaurus. Seems like abelisaurids are more widespread than previously thought. This is the second northen abelisaurid(1st is tarascosaurus which is also from france).

This is the second northen abelisaurid(1st is tarascosaurus which is also from france). 3rd counting Genusaurus which is also from France, as noted above. Abelisaurids have been known to have been widespread in Europe for a while now, but their remains were so scrappy that they were hard to identify and some people even doubted the remains had abelisaurid affinities. Acrovenator seems to have just proved their existence in these areas.
