Skull of the junior synonym S. durobrivensis
Neosteneosaurus is a genus of machimosaurid, known from the Middle Jurassic Oxford Clay of the UK, and Marnes de Dives, France. The type species, N. edwardsi, was originally named as a species of Steneosaurus in 1868,[1] but was moved to its own genus in 2020. Steneosaurus durobrivensis and Steneosaurus hulkei are considered junior synonyms.[2]
In 2015 it was estimated at 7 m (23 ft) in length[3] but later work suggest a length of 6.6 m (22 ft). Even with such measurement, this animal was the largest Middle Jurassic crocodylomorph.[4]
