A little more perspective
Victoria’s March 7, 2022 exhibition announcement identifies the specimen as Horridus and gives a six-to-seven-meter tip-to-tail length. This comparison selects the upper endpoint without turning the broad description into a precise specimen survey or a species-wide maximum.
The living-form outline keeps the forward horn tips, beak and complete tail visible. The source says tip to tail without a more detailed measurement protocol; the horizontal outer outline is the disclosed rendering convention. Skin, soft tissues and horn coverings are restored interpretations rather than surviving features measured on the fossil.
