Volkheimeria

Volkheimeria is an extinct genus of sauropod dinosaurs that lived in what is now Argentina during the Early Jurassic, 178–179 million years ago.

[4] Only a single specimen of Volkheimeria chubutensis is known: the holotype PVL 4077, a partial skeleton from the Cañadón Asfalto Formation of Argentina.

[5] An isolated tooth found in the Cañadón Asfalto Formation, MPEF-PV 10860, may belong to Volkheimeria, though this cannot be proven without more complete specimens.

Some phylogenetic analyses of the taxon have recovered it as a eusauropod, vulcanodontid, or primitive sauropod, though its position is variable due to its incomplete nature.

The phylogenetic analysis of Pol and colleagues in 2022 recovered Volkheimeria as a non-eusauropod based on primitive features of the vertebrae, though alternative placements were identified as closer to either Amygdalodon or Archaeodontosaurus, as shown below.
