The African Bush Elephant is the largest living terrestrial animal, normally reaching 6 to 7.3 metres (19.7 to 24.0 ft) in length and 3 to 3.5 metres (9.8 to 11.5 ft) in height at the shoulder, and weighing between 6,000 to 9,000 kg (13,000 to 20,000 lb).
At up to 32.9 metres (108 ft) in length and 172 metric tons (190 short tons) or more in weight
The largest dinosaurs are many times the size of an elephant. And dinosaur skeletons aren't as well-designed for bearing weight as elephant skeletons. Dinosaurs are impossibly large for planet Earth, but their bones are proof that they must have existed
in order for the largest dinosaurs to function, gravity must have been at least 1/3 (and possibly as low as 1/4) what it is today
The Electric Universe offers a different point of view. Gravity is not a constant. It's a variable that depends on the plasma environment. So Earth in the Mesozoic Era may have had less gravity than it has today
The fossil record is full of animals that could not survive in today's gravity. Arthropods bigger than humans. 3-ft long dragonflies. 2M millipedes. Giant claw reveals the largest ever arthropod" (2007). To say nothing of the dinosaurs -- 350lb flying creatures, enormous saurapods, etc. No way in the world they could make it in today's world. Yet somehow, they used to. A smaller Earth would explain reduced gravity.
This study suggests that if pterosaurs larger than 41kg (or 5.1m wingspan) utilized narrow, albatross-like wings they would not be able to obtain sustainable flight in environments similar to the present. Therefore, if environmental factors such as strength of gravity and density of air have not changed over geological time

Too bad gravity is based on mass and not on size. Wow, some of the things on this site amaze me.
Catastrophist Ted Holden has resurrected the controversy by examining the relationship of size, weight, and strength in animals. (His analysis was the basis for a documentary televised in Japan in Feb, 2004. See photo above.) The strength of muscle tissue is fairly constant among all species. Strength is proportional to the cross section of the muscle: If one muscle is two times the diameter of another, the first will be four times (the square of two) as strong. But weight increases with the volume: A muscle that's twice as big will weigh eight times (the cube of two) as much.
Holden computed the weight/strength ratio of a well-trained human weightlifter and scaled it up to the size of a dinosaur. The weightlifter soon became too big to lift his own weight. Strength, in its relationship with weight, imposes a limit on size. Holden's calculations indicate that the heaviest elephants of today approach that limit
