Ok let's have an interesting battle. Great white from original Jaws or real life Liopleurodon.
In movie shark was described as 25 feet long and 3 tons heavy. Info in the above video. Although I've came across info that model used for shark was 8m long. So we can use 7.6-8m for lenght.
For Liopleurodon. If you guys think about 25m behemoth from Walking With Dinosaurs on BBC in 1999 think again. That was the biggest lie/false info in the history of popular science tv shows. Sort of like Saint Seiya characters being universe buster(I couldn't resist for this one :-) :-) :-) ) . Size estimate for Liopleurodon is 5-7m in lenght 1-1.7tons in weight. Here is the info https://en.wikipedia.org/wiki/Liopleurodon. Actually the max size estimate based on largest speciment dicsovered so far is 6.39m so our good ol' Jaws is bigger. The 6.39m speciment had a 1.29m long skull in condylobasal length and 1.54 m (5.1 ft) in overall length with big teeth so considering bite force I would give liopleurodon the edge. Anyway Sharky also has huge head with teeth almost as long as whiskey glass (if I remember corectly it was stated as "big as a whiskey glass"in the movie) - for that purpose second video has been posted.
For the battle setting. It's a random encounter food is very scarce and both predators are oportunistic and do their best to take each other out.
So my dear Viners who wins in your opinion ?
NOTE: GREAT WHITE SHARK AKA BRUCE FROM THE JAWS IS CONSIDERED AS A REGULAR GREAT WHITE SHARK OF 7.6M OR 25 FEET. SO FEATS SUCH AS BRUCE PULLING A BOAT IN OPPOSITE DIRECTION, SUBMERGING WITH 3 BARRELS ATTACHED, SINKING THE SHIP SHOULD BE IGNORED, SINCE REAL LIFE GREAT WHITE OF THAT SIZE COULDN'T DO SUCH THINGS. IN ORDER TO ACOMPLISH SUCH FEAT IT WOULD NEED TO BE AT LEAST DOUBLE THE SIZE, WHICH WOULD RESULT IN 8 TIMES THE WEIGHT OR 24TONS.
Above part is not me yelling just highliting the important thing.
