	The first fossilised fragment of a skull was discovered by Diane Trevarthen on a beach near Sandown in the Isle of Wight in March 2011. Three months later, the second fragment of the skull was found by Austin and Finley Nathan. The two fragments were donated to Dinosaur Isle. The species that the fragments belonged to was named "Koumpiodontosuchus aprosdokiti", meaning "unexpected button-toothed crocodile".
