Cruxicheiros: new British theropod
It's impressive that such a little island could yield so many theropods...
BTW, the genus name references the locality (Cross Hands Quarry).
_Cruxicheiros_ is not a close relative of _Deinocheirus_.
A new large-bodied theropod dinosaur from the Middle Jurassic of Warwickshire,

Avstract: "Previously undocumented postcranial material from the Chipping
Norton Limestone Formation (Middle Jurassic: Lower Bathonian) of Cross Hands
Quarry, near Little Compton, Warwickshire represents a new large-bodied
theropod dinosaur, distinct from the contemporaneous _Megalosaurus bucklandii_.
_Cruxicheiros newmanorum_ gen. et sp. nov. is diagnosed by a single
autapomorphy, the presence of a proximomedially inclined ridge within the
groove that marks the lateral extent of the posterior flange of the femoral
caput (trochanteric fossa). _C. newmanorum_ shows three tetanuran features:
widely separated cervical zygapophyses, a swollen ridge on the lateral surface
of the iliac blade and an anterior spur of the caudal neural spines. However,
due to fragmentary preservation its affinities within Tetanurae remain
uncertain: phylogenetic analysis places it as the most basal tetanuran, the
most basal megalosauroid (= spinosauroid) or the most basal
