Alierasaurus is a genus of caseid synapsid that lived in Sardinia during the Permian. Because Alierasaurus is only known from partial remains it is difficult to be certain about its full body size. However, these remains seem to be close to comparable in size to the huge Cotylorhynchus, one of the largest land dwelling creatures of the Permian.
