Sauropodomorph evolution across the Triassic-Jurassic boundary: body size, locomotion, and their influence on morphological disparity.

Immediately after the TJB the morphological disparity (WMPD) of Sauropodomorpha has a minor increase (which is only marginally significant after the exclusion of taxa that had to be trimmed for the ordination of the dataset; see Methods ), coupled with a slight increase of the amount of morphospace occupied (SoR) (Figs. 1 a,d, 2 a; Table 1 ).
