A thrilling discovery by Martill and group has declared to have found the footprints of at least six distinct dinosaur species of the rearmost dinosaurs to walk on UK soil 110 million years ago in Kent. It was intriguing for them to find such an array of species in one place. This has been the first record of dinosaur footprints from the Folkestone Formation. It symbolizes the earliest association of dinosaur footprints from England as it could be the last record in this country before they became extinct.
The dinosaurs which are the diverse group of reptiles resided in the Triassic, Jurassic, and Cretaceous period and left several indications, both from plant-eaters and the meat-eaters, in various layers of mud and sand. Fossils of Dinosaurs have been well-known for millennia. Dinosaur bones were first noticed in the late 17th century in England. They are identified to have distinct genera. Egg-laying and nest-building were the features shared by various dinosaurs, irrespective of avian and non-avian species, suggests the evidence. Over the years many researchers have revealed different signs of these extinct creatures in different parts of the world and are still the subject of active research.
Recently, a scientist from the University of Portsmouth and a curator from Hastings Museum and Art Gallery discovered the trackways in the cliffs and on the foreshore in Folkestone, Kent. The natural phenomena like coastal waters and stormy conditions affecting the cliff have aided several such discoveries of these new fossils.
Footprints disclosed that comparatively elevated diversity of dinosaurs in southern England were observed 110 million years ago, at the end of the Early Cretaceous period. The impressions left behind by the dinosaur’s foot pushing into the ground, which also preserves it, were filled by sediments that led to these footprint fossils.
It is found that these footprints are from Ankylosaurs, an armored herbivorous quadruped; Theropods, a three-toed dinosaur alike the Tyrannosaurus rex, which are carnivores; and Ornithopods, bird-hipped plant-eating dinosaurs, having pelvis that resembled a bird’s pelvis.
Many proofs of these footprints are isolated. However, one discovery encompasses six footprints which are categorized as a trackway, when more than one consecutive print from the same animal is noted. The largest footprint found is measured to be 80 cm in width and 65 cm in length, has been seen as that of an Iguanodon-like dinosaur which grew up to 10 meters in length, were herbivorous, and walked easily just on two or on all four legs.
The credit of this remarkable discovery goes to David Martill, a Professor of Paleobiology and team as it is the first record of dinosaur footprints to have been noticed in strata known as the ‘Folkestone Formation’. The evidence suggested that these dinosaurs would have been the last to wander in this country before they were extinct.
It is believed that these discoveries have changed the interpretation of the geology of the Folkestone Formation strata. The documentations suggest there could be more to add to the previously made discoveries about dinosaurs and could still be the subject of active research.

The Function of ABCG2 in hyperuricemia and gout
Madhavi Bhatia,NIPER Guwahati Hyperuricemia is a condition with increased uric acid levels in the blood which results in the deposition of monosodium urate crystals in synovial fluid of joints resulting in gout. Increased levels may be caused due to increased hepatic biosynthesis or reduced renal or intestinal excretion of urate. Most of the urate is […]
