Benoit et al. 2021
“reconstruct Anteosaurus [Figs. 1-4] as an agile terrestrial predator based on the enlarged fossa for the floccular lobe of the cerebellum and semicircular canals of the inner ear.”
Yes, that’s what they wrote. Not the teeth. Not the limbs. The inner ear.
From the Material and Methods section:
“The disarticulated skull (BP/1/7074) of a juvenile Anteosaurus magnificus from the middle Permian of the South African Karoo…”
Phylogenetic context is paramount and required.
There are several problems with the conclusions of Benoit et al. 2021.
- The specimen is not Anteosaurus.
- Dinocephalians were all herbivores.
- Those huge teeth were as sharp as bananas, like hippo teeth.
- The bones of the inner ear do not determine whether you are predator or prey.
What is going on
at the universities nowadays?? Is phylogenetic analysis old-fashioned? Let’s get back to basics.
