Distribution of GCR sites of GCR block Jurassic - Cretaceous Reptilia

In contrast to the manner in which most invertebrate fossils are represented in the GCR, fossils of vertebrates, arthropods (except trilobites) and terrestrial plants do have their own dedicated GCR Blocks, because of the relative rarity of the fossil material. The GCR sites selected for the Jurassic-Cretaceous Reptilia GCR Block represent the British fossil record of terrestrial and aquatic reptiles of the last two periods of the the Mesozoic Era (which spanned from 230 to 65 million years ago (Ma)). At the end of the Cretaceous Period (the last Period of the Mesozoic era) there was a major, global mass-extinction event (the ‘K-T’ event [Cretaceous-Tertiary]), and this had a significant effect on the faunas of the time, with approximatley 85% of species becoming extinct. The Jurassic-Cretaceous time is maked by the emergence and rise of the dinosaurs, thus enabling this ‘unit’ of the fossil record to have a developing, but characteristic, faunal distinctiveness.

Earlier fossil reptiles are afforded their own GCR Blocks, ‘Permian-Triassic Reptilia’and later reptiles are selected for the ‘Tertiary Reptilia’ Block. See PER-TRI-RP and TER-REP.

Palaeontological characteristics

The reptiles evolved from their amphibian forebears over 300 million years ago. The oldest postulated fossil reptile is known from the Carboniferous of Scotland. Reptiles radiated extensively during the Permian Period and the Mesozoic Era, a span of time often referred to as the ‘Age of Reptiles’. Britain’s fossil reptile sites include key Triassic sites that document the pre-dinosaur times, and the unique dinosaurian faunas of Mid Jurassic and Early Cretaceous age. Marine reptiles (plesiosaurs, ichthyosaurs, crocodilians) are richly represented in the Early and Late Jurassic in particular. A number of Tertiary localities have yielded rich faunas of turtles, crocodilians and squamates. Pterosaurs

GCR site selection

Owing to the rarity of fossil reptile material, this GCR Block represents something of a special case with regard to including all of the sites yielding, or that have yielded, significant types and quantities of scientifically important material that help elucidate the evolution, diversification and extinction of the main reptile groups.

The sites selected for this Block aim to represent distinct reptile assemblages showing diversification and extinction associated with the Jurassic and Cretaceous periods, according to 4 GCR networks:

• British Early Jurassic fossil reptiles

• British Mid Jurassic fossil reptiles

• British Late Jurassic fossil reptiles

• British Cretaceous fossil reptiles
