A new Heterodontosaurus ‘elucidates’ ornithischian breathing
Radermacher et al. 2021 bring us
new µCT information on breathing in basal ornithischian dinosaurs, exemplified by Heterodontosaurus (Fig. 1), a biped with canines and large hands with sharp claws.
From the abstract:
“The ornithischian body plan is aberrant relative to other ornithodiran clades, and crucial details of their early evolution remain obscure.”
re: ‘Ornithodira’ – Not valid. In the large reptile tree (LRT, 1882+ taxa; subset Fig. 2) the traditional clade “Ornithodira‘ is a junior synonym for Reptilia or Amniota.
re: ‘Obscure’ – Not true. The LRT documents the crucial details and early evolution of the clade Ornithischia (Fig. 2). Radermacher et al. did not include the Heterodontosaurus precursors, Chilesaurus and Daemonosaurus, nor did they indicate they understood those two taxa were indeed heterodontosaur precursors. Taxon exclusion: the number one problem.
