LIMB-BONE SCALING INDICATES DIVERSE STANCE AND GAIT IN QUADRUPEDAL ORNITHISCHIAN DINOSAURS.

BackgroundThe most primitive ornithischian dinosaurs were small bipeds, but quadrupedality evolved three times independently in the clade.The transition to quadrupedality from bipedal ancestors is rare in the history of terrestrial vertebrate evolution, and extant analogues do not exist.Constraints imposed on quadrupedal ornithischians by their anc

In this study, high strength steel plates made iphone 13 pro max price winnipeg of 30PM steel were subjected to 7.62 Armour Piercing projectiles at the ordnance velocity.Several experiments differing considerably in conditions of interaction between projectiles and plates were performed.Selected parameters were measured before, during, and after ba
