Lessemsauridae

Strict reduced consensus at the genus level of the most parsimonious trees recovered following the phylogenetic analysis. The original dataset is based on the matrix and scorings of Zhang et al. 2019 (except for Irisosaurus) and includes 62 taxa for 364 characters. This reduced consensus displays 39 taxa. It is based on 2 MPTs of 1,300 steps each (CI = 0.33, RI = 0.69). Dashed lines mean that the exact age of the genus is uncertain. Clades: 1, Sauropodomorpha; 2, Plateosauridae; 3, Massopoda; 4, Massospondylidae; 5, Riojasauridae; 6, Sauropodiformes; 7, Lessemsauridae. Squares represent stem-based definitions, ellipses represent node-based definitions.
