Lessemsaurus Classification
Exhibit in Singapore A cladogram after Pol, Garrido & Cerda, 2011,[ 9] Lessemsaurus and Antetonitrus
In 2018, Apaldetti et al. recovered it as part of a clade they named Lessemsauridae , after Lessemsaurus . Their cladogram is reproduced below:[ 10]
The following cladogram shows the position of Lessemsaurus outside of Sauropoda, according to Oliver W. M. Rauhut and colleagues, 2020:[ 11]
