The Earthcache


A cache 'n' dash earthcache. You may have passed this site many times, but little did you know, that beyond the gates, there's a disused quarry site of important geological matters! The cache can be done along with Stag Rambler's 'Hinchwick Valley' series, or my own Kildanes series. Some of the old quarry workers houses can be seen from the footpath that runs towards my first ever find 'Hinchwick Valley 7'.


Geology


This geologically important site has a relatively thick sequence of limestones and thin clays of key importance in similar, but thinner, sequences elsewhere in Gloucestershire. These rocks, are believed to have been laid down around 170 million years ago in a warm, sea that covered much of present-day Gloucestershire Conditions are believed to have been similar to those which exist today at the carribean structures and the type of fossils found within the rocks. They are of great significance since they enable geologists to date some rock units and place them within the Jurassic rock succession. Hornsleasow Quarry is a key site in the reconstruction of an ancient sea that covered much of present-day Gloucestershire in Middle Jurassic times.



History


In 1987 Kevin Gardner and his six year old daughter Lisa found some fossils in the quarry . They thought there might have been a dinosaur nearby, but actually there were dozens and more....They included teeth and bones of crocodiles, furry reptiles such as turtles, flying pterosaurs and many more. In amongst them were tiny teeth of some of the very earliest mammals. Larger fossils included those of the Stegosaurus and others. In total there were over 200 kg of dinosaur bones recovered at the site! That's a whole lot of dinosaurs!
