Utahraptor vs Megalania

which is why evidence of 23 meter long individuals still exists and were probably the main hunters of such prey. might i add that that study was made in 2002. the most recent one in 2012 has brought a STV length of the largest indaviduals to a total of 10 feet. once again, making the average far larger then the mear 11 feet total average length 15 foot maximum length anounced by Stephen Wroe in freaking 2002.

i misunderstood your first post, but hows this for a rebutal?

Like the other members of this unique varanid lizard clade, the jawbones of V. priscus are also relatively gracile compared with the robust skull and the proportionally larger teeth similarly serrated (Fig. 3). Application of the “extant phylogenetic bracket” comparative approach (32) indicates that V. priscus used the same combined arsenal of large serrated teeth with anticoagulant and hypotension-inducing venom. Maximal body masses exceeding 2,000 kg and 7 m in length have been proposed for V. priscus (although such numbers rely on extrapolation well beyond available data ranges for extant lizards).

Our multidisciplinary analyses paint a portrait of a complex and sophisticated tooth/venom combined-arsenal killing apparatus in V. komodoensis and its extinct close relative V. priscus. Thus, despite a relatively weak skull and low bite force, we suggest that the combination of highly and very specifically optimized cranial and dental architecture, together with a capacity to deliver a range of powerful toxins, minimizes prey contact time and allows this versatile predator to access a wide range of prey including large taxa. These results indicate that V. priscus was the largest venomous animal to have ever lived.

The predatory ecology of Varanus komodoensis (Komodo Dragon) has been a subject of long-standing interest and considerable conjecture. Here, we investigate the roles and potential interplay between cranial mechanics, toxic bacteria, and venom. Our analyses point to the presence of a sophisticated combined-arsenal killing apparatus. We find that the lightweight skull is relatively poorly adapted to generate high bite forces but better adapted to resist high pulling loads. We reject the popular notion regarding toxic bacteria utilization. Instead, we demonstrate that the effects of deep wounds inflicted are potentiated through venom with toxic activities including anticoagulation and shock induction. Anatomical comparisons of V. komodoensis with V. (Megalania) priscus fossils suggest that the closely related extinct giant was the largest venomous animal to have ever lived.

Which does not equate into a Komodo dragon-sized Megalania prisca preying upon 2 ton animals.

which would be ignoring the fact that EVERY single varanid is venomous

venom is a basal adaptation just as feathers are to birds

it is down right retarded to assume magalainia lacks venom

No one here thinks it wasn't venomous, I'm just referring to the possibility it wasn't venomous
