Template:Short description Template:Speciesbox
Lessemsaurus is an extinct genus of sauropodiform dinosaur belonging to Lessemsauridae.
Naming and description
The type species, L. sauropoides, was formally described by José Fernando Bonaparte in 1999 in honor of Don Lessem, a writer of popular science books. It was found in the Los Colorados Formation of the Ischigualasto-Villa Unión Basin in La Rioja Province, Argentina.[1]
It was discovered in strata dating to the Norian stage, around 210 million years ago.[2][3] It is estimated to have reached Template:Convert long and weighed over Template:Convert, possibly up to Template:Convert, in maximum body mass.[4][5][6][7]
Classification
A cladogram after Pol, Garrido & Cerda, 2011,[8] illustrates a possible placing of Lessemsaurus and Antetonitrus in Sauropodomorpha: Template:Clade
In 2018, Apaldetti et al. recovered it as part of a clade they named Lessemsauridae, after Lessemsaurus. Their cladogram is reproduced below:[9]
The following cladogram shows the position of Lessemsaurus outside of Sauropoda, according to Oliver W. M. Rauhut and colleagues, 2020:[10]
