For many years, the only described spinosaur from the United Kingdom was the famous baryonychine Baryonyx. That finally changed in 2021 with the announcement of two additional species: Riparovenator milnerae and Ceratosuchops inferdios. Both were discovered in the Wessex Formation on the Isle of Wight, both are estimated to have been around 8.5 metres in length, and both have been determined to be more closely related to Suchomimus than Baryonyx.
