event-mechanism · mediumDigital models built from the hatchling, yearling PVL 4587 and adult Mussaurus sample move the estimated centre of mass forward and support a bipedal-to-quadrupedal ontogenetic stance shift; the stance is a model result assembled from several individuals, not a preserved gait or evolutionary stage.
claim:event:mussaurus-ontogenetic-stance-modelfossil-range · highMussaurus is represented by hatchling, yearling and adult specimens from the Patagonian sample used for its ontogenetic models; these individuals do not establish complete genus endpoints or an evolutionary ladder.
