Completing our survey of British non-avian dinosaurs, we here review the ornithischians of Britain. Heterodontosaurids are present in the Lower Cretaceous Lulworth Formation of Dorset, and a few earlier possible records imply a long presence in the region of this clade. Britain’s thyreophoran record is rich and includes the earliest well-represented taxon, Scelidosaurus, as well as Middle Juras...

-The mid-Mesozoic time was characterized by massive reorganization of the ecological structure of benthic marine communities. Although the general pattern of this "Mesozoic Marine Revolution" has been extensively documented, little is known about how it affected the taxonomic and morphologic diversities of individual lineages of organisms. Here I document group-level dynamics of the Mesozoic ch...

The Dinarides, together with the Albanides and Hellenides, preserve stratigraphic successions derived from eastern margin of Adriatic microplate remnants ophiolites obducted Maliac-Vardar branch Neotethys Ocean. main stages in Mesozoic geodynamic history are: 1) rifting leading to opening Maliac Ocean Late Anisian, 2) onset an east-dipping intra-oceanic subduction Early-Middle Jurassic sea-floo...

Subduction zones are the primary regions on Earth today where crust recycling takes place, and through geological time they have been the sites of continent formation. Many of the key elements (e.g., Th, rare earth elements, Ba, and Be) that are important in understanding crustal growth are sequestered in the sedimentary column and in the uppermost oxidized portions of the volcanic section of o...
