       Aerosaurus is considered to have been a precursor to later pelycosaurs like Varanops,‭ ‬yet there are some questions as to the true nature of Aerosaurus.‭ ‬The teeth of Aerosaurus are sharp and recurved backwards like those of a predator,‭ ‬yet they are very tightly packed so that they form a continuous row kind of like a saw blade.‭ ‬This could denote a specialised method of feeding like a filter feeder,‭ ‬or perhaps being a form of‭ ‬rudimentary‭ ‬rake for stripping fronds of vegetation from fern-like plants.‭
       In addition to the teeth,‭ ‬the ribs were also quite long which meant that the body was deeper with possibly more room for a larger digestive system which may have been necessary for processing plant matter.‭ ‬Aerosaurus is also noted for having a proportionately long tail,‭ ‬almost as much as half of the total body length.
