Size of Ischigualastia jenseni relative to a human

It is regarded as larger than its later, more famous relative Placerias, which was up to 3.5 meters long (11.5 ft) and weighed one to two tonnes (1.1 to 2.2 short tons). Unlike Placerias, it lacked tusks. It was a large quadrupedal herbivore, most common at the base of the Ischigualasto Formation.[2]
