In the hard sciences such explanations that can explain everything and rule out no possible observations are usually considered empirically empty and worthless.
In a monograph in 2007, I suggested that these larvae may not be genuine dragonflies of the suborder Anisoptera.
The fossil is almost complete, only the abdomen is missing and was likely bitten off by a predator.
This is a case of evolutionary biology trying to explain away the data that otherwise was not directly expected under their model.
