Chance of an answer: Not out of the realm of possibility. “I think with the new methods of muscle reconstruction and 3D modeling out there, we will definitely narrow down the possibilities of uses for the forelimb,” says Burch. The Nation’s T. rex contains one of most complete forelimbs in the fossil record. “That could lead us to something,” says Carrano. These results match predictions made from skeletal anatomy, providing the first molecular evidence for the evolutionary relationships of a non-avian dinosaur.” Chris Organ This is because paleontologists have determined that dinosaurs are more like birds than any other animal. Scientists don’t know if T. rex was totally warm blooded or cold blooded, but they think that the giant’s metabolic rate was probably somewhere in between that of crocodiles and birds. A study published last year in PLOS One suggests that cold blooded energetics could not have fueled dinosaurs’ active lifestyles, and thus they probably didn’t regulate their body temperature exclusively by moving into the sun, as modern lizards and crocodiles are known do. If the PLOS One study is true, it is even more likely that newborns had feathers. Chance of an answer: Nil. The only thing that would prove it is a Mesozoic-era recording of the creature.

Chance of an answer: “We don’t know the logistics,” says Carrano. “We can theorize; these are pretty big animals—seven-ton animals that stood on two legs.” Scientists might look to giraffes or elephants, but they obviously aren’t perfect models. Video: Meet the Robinsons/Disney The ominous roar of a T. rex, made familiar by the Jurassic Park movies, is nothing more than the product of a filmmaker’s creative imagination. Scientists look to modern relatives of the T. rex—birds and reptiles—for indications of what the dinosaurs might have sounded like, if they made any vocalizations at all. In reality, their calls may have been more like a shriek or a grumble than a roar. “We can guess that it might have sounded like a crocodile or an ostrich, but definitely not a lion and therefore no roaring or purring,” says Carrano.The Yutyrannus, described in 2012, are the largest known dinosaurs with feathers—a patch of fossilized skin shows shaggy body feathers, similar to an Emu. Yutyrannus was related to T. rex and measured 30 feet long and weighed more than 3,000 pounds.” Illustration by Brian Choo.

Collagen is the main component of connective tissue and one of the most abundant proteins in living animals. Oh, I just thought of something. If that is true, then it also answers a few age-old questions. Like: The king of reptiles, though mighty and well documented in the fossil record, remains largely a mystery to paleontologists who have yet to understand the creature’s basic lifestyle and biology. We've culled scientific reports to bring you five questions that have yet to be answered:Until a specimen is found with preserved imprints of feathers, though, the jury is out. “We have some opportunity to know if they had feathers because we can find impressions,” says Matthew Carrano, curator of dinosaurs at the National Museum of Natural History. “But it’s highly unlikely that we will ever know its color or the texture of its skin.” We can’t extract DNA from collagen, at least not Dino DNA. That’s because DNA breaks down too fast and dinosaurs are too old.
