Portrait of the spinosaurid Riparovenator milnerae from the Early Cretaceous of England. The remains of this theropod were found on the Isle of Wight and were initially attributed to Baryonyx. These include fragments of the skull and a series of tail vertebrae. In 2021, they were assigned to a new genus based on a combination of features of the skull bones. Like other dinosaurs from the Baryonychinae subfamily, it had a long and narrow snout, although not as specialized as that of Spinosaurus. A related Ceratosuchops from the Isle of Wight was described in the same publication. If these dinosaurs lived at the same time, they may have hunted at different times of the day or preferred different hunting grounds, but it is also possible that they were not contemporaries.
