Aristosuchus pusillus

 Fig 1.- Reconstruction of Aristosuchus.

Continuing the series of British dinosaurs with the compsognathid Aristosuchus… This one is known from fragmentary postcranial remains from the Isle of Wight, dating from the Early Cretaceous Barremian stage, and originally described in 1876 by Sir Richard Owen (as “Poikilopleuron pusillus”). This little dinosaur was probably very similar to the Late Jurassic Compsognathus from Germany and France and measured about 2 meters in length.
