Allain proposes (in the "Poekilopleuron" valesdunesnsis paper) the following
"Phylogenetic definitions. Megalosauridae is defined here as Poekilopleuron?
valesdunensis, Torvosaurus and Afrovenator, and all descendants of their
The Torvosaurinae are defined here as all Megalosauridae that are more
closely related to Torvosaurus than to either Poekilopleuron or Afrovenator;
this clade includes Torvosaurus and tentatively Edmarka.
The Megalosaurinae are defined here as all Megalosauridae that are more
closely related to Poekilopleuron than to Torvosaurus. This clade includes
Eustreptospondylus, Poekilopleuron and Afrovenator."
Not exactly the topology I find (but close) and not exactly the definitions
I would propose, but there it is...
