Researchers in the British county of Kent have discovered tracks probably belonging to the last dinosaurs that roamed the island, according to a study published in the scientific journal Proceedings of the Geologists’ Association.
According to the British daily The Guardian, the last dinosaurs became extinct about 66 million years ago when an asteroid hit our planet. However, in the British Isles, they became extinct due to large-scale floods much earlier than 110 million years ago.
At that time, these islands were located on the site of present-day northern Morocco or southern Spain. At that time, the habitable soil quickly disappeared due to rising sea levels. However, one sandy beach in the south of England near the white cliffs of Dover was an ideal place for dinosaurs to live. The sea washed up enough dead fish for carnivores and a lot of fresh vegetation hung over the beach, one of the authors approached. study and Dave Martill, Professor of Paleobiology at the University of Portsmouth.
Researchers discovered fossils of several species of dinosaurs in an area prone to storms in Folkestone. The size of the tracks suggests that they were medium-sized creatures, including armored herbivorous ankylosaurus, carnivorous theropods, and avian ornitopods.
“This layer of rock is the last opportunity to find evidence of dinosaurs walking across Britain. And I don’t understand why no one has found them yet, because these rocks have been exposed for more than a hundred years, “said Martill.
The main author of the study, Philip Hadland from the museum and art gallery in the British city of Hastings, discovered unusual footprints in the stone in 2011 and, in his own words, immediately seemed like traces. “(My impressions) contradicted what most geologists thought of these rocks, but I went looking for more clues, and when the tides eroded more rock, I found even better (specimens),” Hadland said, adding that then it took some time for the scientific community to acknowledge their authenticity.
A professor of paleontology at the University of Edinburgh told The Guardian that while these are the youngest footprints found in Britain, it is likely that even younger footprints will be found in the future, so in this case they are not the last dinosaurs in Britain.
