Poeklopleuron ( Latin Poekilopleuron , from other Greek ποικίλος - different and πλευρόν - rib) - a genus of carnivorous dinosaurs from the suborder Theropods. He lived in the Jurassic period (the Bati tier , about 168-165 million years ago). The genus name was used in different variants of the name, but only Poekilopleuron is correct. Type species - P. bucklandii . Little remains have survived to this day, since the bones of the holotype were destroyed in World War II , but some bones survived.

The holotype, which was housed at the Musée de la Faculté des Sciences de Caen, included fingers, gastralia, caudal vertebrae, chevron, left forelimb, ribs and hind limb. Poekilopleuron is a megalosauridae species with a long and complex history. The genus was first named and described by Jacques Aman Ed-Delongshan in 1838. The name comes from the Greek Greek. ποικίλος - “diverse” and πλευρόν - “rib”, due to three types of edges. The species name is given in honor of William Buckland .
Ed-Delongshan believed that the specimen might belong to one of the earliest species. If so, then the name should be changed. Indeed, after 1879, Poekilopleuron was often referred to as Megalosaurus bucklandii . Ed Delongshan's choice caused some classification problems. Friedrich von Hunet in 1923 came to the conclusion that these are the remains of a new species of megalosaurus . Since both lizards were called bucklandii , it was difficult to distinguish between them. Therefore, von Hyun renamed the species Megalosaurus poekilopleuron .
A distinctive feature of Poekilopleuron was its forelimbs. Their length is about 60 cm, they are very distinguished in the body structure of these theropods . Unlike later predators, whose forelimbs were smaller in relation to the body, the “arms” of the poekilopleuron were long and powerful. Most of their length was occupied by an elongated but powerful muscular humerus . The forearms were short and strong; this is a common feature of the Poeklopleuroron with a slightly later and significantly larger American relative torzaurus . A unique feature is the absence of an ulnar process on the ulnar bone.
