in the same 1836 publication, eudes-deslongchamps also named the type species of "poekilopleuron", "p. bucklandii". eudes-deslongchapms noted similarities with some material of "megalosaurus bucklandii" and "poekilopleuron", and chose the species name "bucklandii" for "poekilopleuron", so that it the two genera were synonymized, only the genus name would be suppressed. the generic name is derived from greek ποίκιλος, "poikilos", "varied", and πλευρών, "pleuron", "rib", a reference to the three types of rib present. the specific name, honouring william buckland, was deliberately identical to that of "megalosaurus bucklandii".
