Rex Gilroy’s early Australian giant-lizard claims

Record summary

Rex Gilroy began publicizing claims about living giant monitor lizards and other unknown Australian animals during the 1960s, before becoming a prominent self-taught cryptozoological investigator. His material often involved alleged tracks, eyewitness reports, and interpretations connected with the extinct monitor Varanus priscus, then commonly called Megalania. The lead matters because it documents an identifiable investigator and an early stage of a long-running controversy. Verification requires separating Gilroy’s publications and interviews from independent reports and from later claims that enlarged or reorganized the original evidence.
