UK Marine Reptile & Phosphate Fossils This page is where you will find all UK Marine Reptile fossils. Many of the once famous collecting locations are now no longer quarries, but wildlife parks, nature reserves or shopping centres and car parks.
Pliosaur/Plesiosaur bone sections, & cut and polished from Oxfordshire, UK Small and medium size sections of Pliosaur bone sections from Jurassic Kimmeridgian Clay. We also have some Sauropod bone from the same locations -you can find these on the Dinosaur bone page. It is not unusual for land animals and marine deposits to be found together in places. Many are reworked marine deposits that have eroded into slightly newer and younger clays and silt. The difference between the marine reptile and land based dinosaurs can be seen in the bone structure. Dinosaur bone seems to have a much coarser bone structure most probably to do with the influence of oxygen on bone growth esp. in Sauropods that were mostly Huge. These were found in quarries as blocks of eroded bone sections, often shattered from machinery or the elements. To get the best out of them, the collector cut and polished them, and this way we can admire the complex bone structure of these magnificent marine animals.
