When paleontologists found the Archaeopteryx they finally had a well-preserved fossil that showed only slight differences between Archaeopteryx and theropods. The 2nd evidence is feathers. Over the years you may have noticed that there have been more and more pictures of dinosaurs with feathers. Our traditional ideas about what Velociraptors, or even the T-Rex, looked like are now shifting from reptile-like to bird-like. Studying changes in proteins can actually give us more insights about evolution than just looking at the DNA. Proteins can yield clues about the age of a sample or about the environment in which an animal lived or was buried. Schweitzer That’s the scientific definition. Let me try to break it down for you (no pun intended) in simple words. 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.”
This is because paleontologists have determined that dinosaurs are more like birds than any other animal. But wait. There’s more. Horner as revealed that he has already found the gene that ‘turns on’ teeth. In June of last year, the Smithsonian reached an agreement with the U. S. Army Corps of Engineers, and the skeleton is on loan to the Smithsonian for the next 50 years. At 80 to 85 percent of a full T. rex skeleton, the Wankel T. rex is among the most complete fossils of its kind unearthed, second only to the Chicago Field Museum’s “Sue,” which the Smithsonian tried to acquire in 1997. Beyond these stunning skeletal displays, paleontologists have found some 50 T. rex specimens, since Henry Fairfield Osborn first described the species in 1905. These results match predictions made from skeletal anatomy, providing the first molecular evidence for the evolutionary relationships of a non-avian dinosaur.” Chris Organ 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.
The Tyrannosaurus Rex chicken arms are made from Biodegradable PLA Plastic.
As for T. rex babies: Perhaps the young were born with a fluffy feather coat, a common phenomenon in birds, and then lost the majority of their feathers once they reached adulthood. “The bigger you are the harder it is to lose heat,” says Schweitzer. “So, when you’re little, as most critters are when they hatch out, you need insulation or their metabolism would have to be fast enough to maintain body temperature.” Chance of an answer: Nil. The only thing that would prove it is a Mesozoic-era recording of the creature. Ok, so here’s the-big-idea. Collagen is a protein and proteins are important because they tell us a lot about an organism. 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.

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. Or, remembering all the warning of Dr. Malcom in the Jurassic Park series, it could just go horribly bad. All seriousness aside, I think the next 10 years are going to be very interesting in the world of dinosaurs. At least there is a sense of hope, a glimmer of light, that promises to answer many many more questions about dinosaurs.We have discovered that dinosaur DNA, and all DNA, just breaks down too fast. We’re just not going to be able to do what they did in ‘Jurassic Park.’ We’re not going to be able to make a dinosaur based on a dinosaur.” Horner Finally, In 2011, samples of amber from the Cretaceous era were discovered that contained preserved feathers. This led paleontologist to conclude that “some of the feathers were used for insulation, and not flight.”
Yes, you’ve read that right! Apparently, someone has come up with the hilarious idea of giving these farm fowls a pair of dinosaur arms. Although this might come as a surprise to many, several studies have actually confirmed the kinship between T-Rex and birds. In fact, contrary to popular belief, the mighty predator shared more of its genetic makeup with birds than with reptiles. Chance of an answer? It’s looking more and more likely that T. rex had feathers, but coloration and skin texture remain unknown, for now.
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. Oh, I just thought of something. If that is true, then it also answers a few age-old questions. Like:
