Paleontologists announced the discovery of a new dinosaur species, Istiorachis macarthurae, on the Isle of Wight. This herbivore, which lived over 120 million years ago, is distinguished by a large sail-like structure on its back. Initially mistaken for a known species, a re-examination revealed its unique spine. Scientists believe this sail likely served as a mating display, similar to a peacock's tail, rather than a temperature regulator. The discovery highlights the diversity of Iguanodontian dinosaurs during the Early Cretaceous period.
