 to Through the analysis of the middle ear region of "Dendrerpeton acadianum", it could be determined that this taxa has a tympanic ear that is not there as a means of support for the palatoquadrate, but rather the positioning of the stapes indicates that it is used for the movement of sound.This morphology demonstrates "Dendrerpeton" having a hearing system that mimics that of anurans.This was contrary to what was previously thought, which was that it had a "squamosal embayment" rather than a otic notch.
