Transcription
Description
Ledumahadi was likely a quadruped, as determined by analysis of the circumference of its humerus and femur compared to those of other dinosaurs. It would have had very large, robust forelimbs, consistent with those of its relatives. Unlike those of later sauropods, these limbs were naturally flexed, as opposed to being purely columnar.[1][3]
Size
Size of Ledumahadi compared to a human
At its time in the Early Jurassicepoch, Ledumahadi is thought to have been the largest land animal that had ever lived.[1] At the age of 14 years, L. mafube is estimated to have reached a maximum size of around 12 tonnes (13 short tons) in body mass, significantly larger than its relatives. L. mafube was more comparable to the later sauropod Diplodocus in body mass.[1][3] An ichnotaxon named Tetrasauropus belongs to a sauropodomorph that is estimated to have a hip height of 2 m (6.6 ft), meaning that it likely belongs to Ledumahadi.[4]
Classification
A phylogenetic analysis of Ledumahadi mafube was performed by McPhee and colleagues, which found it to belong to a recently recognised clade of sauropodiformes called Lessemsauridae, including the closely related South African Antetonitrus and Lessemsaurus from Argentina. Another lessemsaurid described in 2018, Ingentia, could not be included in their analysis but was also recognised as belonging to Lessemsauridae. The results of McPhee and colleagues' analysis are shown in the cladogram below:[1][3]
The size of the taxon was deemed to be important in the wider picture of sauropodomorph evolution, similar to its other lessemsaurid relatives. Living only a few million years after the Triassic-Jurassic extinction event, it indicates that this event must have either had only a small effect on body size within the sauropodomorph lineage, or may have not affected it at all. Significance was also found in the magnitude of the size itself—it lacked the columnar limbs that characterized its more derived relatives, thought to be a key adaptation in body size evolution. Ornithischian dinosaurs reach their largest sizes around a similar size of 12 to 17 tonnes in weight. This may have been the upper limit for dinosaurs without adopting the characteristics found in true sauropods, which grew to be several times the weight of Ledumahadi.[1][3]
