Acamptonectes [SEP] Classification
In 2012, Fischer and colleagues found "Acamptonectes" to be a member of the family Ophthalmosauridae based on several characteristics: the reduced extracondylar area (a band of bone surrounding the occipital condyle), the plate-like dorsal trochanter of the humerus, the presence of a facet at the front of the humerus' bottom end for a paddle bone, and the lack of notching in the paddle bones (the latter was considered to be homoplastic, or independently acquired). They also found it to be more closely related to other ophthalmosaurids than "Arthropterygius" based on the large processes of the basipterygoids (also bones of the braincase), the lack of a peg on the basioccipital, and the large trochanters of the femur.
