Palaeontologists have found a 150-million-year-old abdomen stone on England’s Jurassic Coast.
The Jurassic Coast is a World Heritage Website that stretches for 96 miles from Exmouth in East Devon to Studland Bay in Dorset. The shoreline spans 185 million years of geological historical past, with an nearly steady sequence of rock formations overlaying the Triassic, Jurassic and Cretaceous durations.
The abdomen stone was discovered by Dr Steve Etches MBE in Kimmeridge, Dorset, and originates from the Jurassic period. The discover extends the vary of identified calculi (abdomen stones, bladder stones and many others) within the fossil file by nearly 59 million years.
Nigel Larkin, a palaeontologist and Visiting Analysis Fellow on the Faculty of Organic Sciences on the College of Studying, mentioned: “I used to be fascinated by this mysterious object and was decided to find what it was. Except abdomen stones are literally discovered preserved inside a skeleton it’s nearly not possible to inform what kind of animal it might need shaped inside.”
“The dimensions of this abdomen stone, and contemplating it was present in clay from the Higher Jurassic period, signifies it most probably shaped inside a big marine reptile reminiscent of an ichthyosaur, plesiosaur, pliosaur or crocodilian. The abdomen stone didn’t come from a dinosaur – as dinosaurs lived on land – however that is nonetheless a really thrilling and uncommon discovery,” added Larkin.
Dr Ivan Sansom, Senior Lecturer in Palaeobiology on the College of Birmingham, carried out microscopic analyses of the stone to find out the precise construction of the specimen and what minerals it was fabricated from. He concluded the specimen has all of the traits of a calculus that shaped in a gastro-intestinal tract – generally known as a ‘abdomen stone.’
