Eustreptospondylus ( ;), from (Ancient Greek εὖ (eû), meaning "well", στρεπτός (streptós), meaning "twisted", and σπόνδυλος (spóndulos), meaning "vertebra"), is an extinct genus of megalosaurid theropod dinosaur, from the Callovian and Oxfordian stages of the Jurassic period (some time between 166 and 154 million years ago) in southern England, at a time when Europe was a series of scattered islands (due to tectonic movement at the time which raised the sea-bed and flooded the lowland).

Metriacanthosaurus (meaning "moderately-spined lizard") is a genus of metriacanthosaurid dinosaur from the Oxford Clay Formation of England, dating to the Late Jurassic period, about 160 million years ago (lower Oxfordian). It is the only metriacanthosaurid currently named from outside of Asia.
