Relatively ultra rapid dinosaur growth and dinosaurs had monstrous bird like multiple lung sacks?
Could they have grown ultra quickly during their lifetime due to a different environment? Higher or lower atmospheric pressure... smaller strength of gravity?
Could these particular lessemsaurids dinosaurs have been transformed during an electromagnetic evolutionary event? Or altered when in embryonic state?
Will this Ingentia prima dinosaur species be only found in a niche area or will others be found around the world?
The animal used a novel strategy to become super-sized, involving very fast growth spurts and efficient bird-like lungs, say palaeontologists. The fossil was found in the northwest of Argentina during a field trip. The scientists found four skeletons in all, one of a new species and three of related dinosaurs.
The dinosaur dates back to the Triassic, about 47 million years before the iconic long-necked plant-eaters Diplodocus and Brachiosaurus appeared on the scene. It wasn't as large, weighing about 10 tonnes. But its discovery is a surprise, coming so early in dinosaur evolution.
Like dinosaurs that lived later, it had bird-like air sacs, which may have been needed to keep large animals cool and supply large amounts of oxygen.
Growth rings seen in its bones show it grew very fast. "We could observe in the bones [from the growth rings] that they had markedly high-growth periods"

More convergent evolution?
Or electrical energy evolution? Localised like Mungo Man or in a larger area similar to the Wallis Line?
Or nature using similar basic building structures and techniques when appropriate and nothing to do with serial evolution successes and failures?
The remarkable discovery of four lessemsaurid skeletons forces us to rethink when, and how, dinosaurs got so huge. We used to think that the first giant dinosaurs arose in the early part of the Jurassic Period, after supervolcanoes caused a global extinction at the end of the Triassic. But the lessemsaurids tell us that at least some dinosaurs were able to attain giant sizes during the latest part of the Triassic, before the extinction.
What is really unexpected is that the lessemsaurids achieved their huge bodies independently of the gigantic sauropods like Brontosaurus and Diplodocus, which did indeed evolve later during the Jurassic.
