Fossils of the genus reached a length of up to 120 centimeters. The majority of the finds, however, are much smaller. Its habitat were lagoons and coastal waters. The limbs were not fully reshaped for aquatic life. The name "Pachypleurosaurus" comes from the Greek ( Greek : pachy "thick", pleuro " rib " and sauros "lizard"), which refers to the thickened rib bones.
