Abstract
The locomotion peculiarities of Macropodosaurus gravis are considered based on the study of these dinosaurs’ footprints from the Lower Cretaceous deposits of Tajikistan and morphological and functional analysis of the postcranial skeleton of segnosaurs. A hypothesis about their plantigrade ability is substantiated.
