*From " Dominance of the Early Triassic " section : " However, there are weaknesses in all these points : the chest of " Lystrosaurus " was not significantly larger in proportion to its size than in other dicynodonts that became extinct; although Triassic dicynodonts appear to have had longer neural spines than their Permian counter-parts, this feature may be related to posture, locomotion or even body size rather than respiratory efficiency; " L . murrayi " and " L . declivis " are much more abundant than other Early Triassic burrowers such as " Procolophon " or " Thrinaxodon " . "-Sentence seems overly long and difficult to follow.
