Wait, what? You’re kidding, right? Say it ain’t so. Well, there is some disagreement about this among paleontologists, but, according to Steve Brusatte, while they may not have matched up to Marc Bolan in a boa, and the feathers in question were maybe more like porcupine quills than the fluffy sort of plumage one might find on, say, an ostrich, those things poking out of the T. rex’s body were indeed feathers. And if you think the notion of a 40-foot, seven-ton eating machine, with ginormous, dagger-like, railroad-spike-size teeth bearing down on you, is scary, consider this. They travelled in packs. Sweet dreams! I have to confess that after reading this chapter, I did indeed have at least one dream that night that included multiple representatives of the T. Rex family. Not a wonderful image to induce one back to the land of Nod, after having bolted suddenly upright from REM sleep in fight-or-FLIGHT mode.HopeA Tyrannosaurus Rex is a thing with feathers.

You can spot Thomas Carr, now a professor at Wisconsin’s Carthage College, from a mile away. He has the fashion sense of a 1970s preacher and some of the mannerisms of Sheldon Cooper from The Big Bang Theory. Thomas always wears black velvet suits, usually with a black or dark red shirt underneath. He has long bushy sideburns and a mop of light hair. A silver skull ring adorns his hand. He’s easily consumed by things and has a long-running obsession with absinthe and the Doors. That and tyrannosaurs.Brusatte also shamelessly namedrops every A-list paleontologist he has encountered. Of course, it sounds like those encounters were substantial, so I guess it’s ok, but… I was reminded a bit of Bill Clinton’s memoir, in which it seemed that every person he mentioned had either changed his life or was a close personal friend. In a way, the book constitutes a this-is-your-life look at Brusatte’s paleontology career (boy meets bone?), with appearances by many of the people he had learned from or worked with. (they are legion) In addition to the studies mentioned in the book, he is the author of a widely taught textbook, Dinosaur Paleobiology. He is the paleo expert in residence on Walking with Dinosaurs (so much better than the sequel, Fleeing from Dinosaurs) on the BBC.

Baron Franz Nopcsa von Felso-Szilvas…was literally an aristocrat who dug up dinosaur bones. He seems like the invention of a mad novelist, a character so outlandish, so ridiculous, that he must be a trick of fiction. But he was very real—a flamboyant dandy and a tragic genius, whose exploits hunting dinosaurs in Transylvania were brief respites from the insanity of the rest of his life…[he had] expertise in espionage, linguistics, cultural anthropology, paleontology, motorbiking, [geology, and god knows what else].

Jingmai [O’Connor] calls herself a Paleontologista—fitting given her fashionista style of leopard-print Lycra, piercings, and tattoos, all of which are at home in the club but stand out (in a good way) among the plaid-and-beard crowd that dominates academia…she’s also the world’s number-one expert on those first birds that broke the bounds of Earth to fly above their dinosaur ancestors.

It was the worst day in the history of our planet. A few hours of unimaginable violence that undid more than 150 million years of evolution and set life on a new course. T. rex was there to see it.
“Hadrosaurs and ceratopsians eating flowers. Smaller ornithischians feeding on shrubs, the pachycephalosaurs head-butting each other in tests of dominance. Poodle-size raptors prowling for salamanders, lizards, even some of our early mammal relatives, all of which are known from Hell Creek fossils. A variety of omnivores—Troodon and the freakish oviraptorosaurs—picking up whatever scraps the more specialized meat-eaters and plant-eaters forgot about. Other dinosaurs I haven’t yet mentioned, like the speed-demon ornithomimosaurs, and the heavily armored Ankylosaurus, fighting for their own niches. Pterosaurs and primitive birds soaring overhead; crocodiles lurking offshore in the rivers and the lakes. Not a sauropod to be found, and the King—the great T. rex itself—ruling over all of it.
This was the Late Cretaceous of North America, the final flourish of the dinosaurs before disaster struck.”
“But there was more to it than that, because continents don’t just split up and call it a day. As with human relationships, things can get really nasty when a continent breaks up. And the dinosaurs and other animals growing up on Pangea were about to be changed forever by the aftereffects of their home being ripped in two.”
“After some of the largest volcanic eruptions in Earth history desecrated ecosystems, dinosaurs became more diverse, more abundant, and larger. Completely new dinosaur species were evolving and spreading into new environments, while other groups of animals went extinct. As the world was going to hell, dinosaurs were thriving, somehow taking advantage of the chaos around them.”
“Triceratops, like its arch-nemesis T. rex, is a dinosaur icon. In films and documentaries, it usually plays the gentle, sympathetic plant-eater, the perfect dramatic foil to the Tyrant King. Sherlock versus Moriarty, Batman versus the Joker, Trike versus Rex. But it’s not all movie magic; no, these two dinosaurs truly would have been rivals 66 million years ago. They lived together along the lakes and rivers of the Hell Creek world, and they were the two most common species there—Triceratops making up some 40 percent of Hell Creek dinosaur fossils, T. rex coming in second at about 25 percent. The King needed immense amounts of flesh to fuel its metabolism; its three-horned comrade was fourteen tons of slow-moving prime steak. You can figure out what happened next.”![]()
“This means that dinosaurs are still among us today. We’re so used to saying that dinosaurs are extinct, but in reality, over ten thousand species of dinosaurs remain, as integral parts of modern ecosystems, sometimes as our food and our pets, and in the case of seagulls, sometimes as pests.”

“A T. rex didn’t just mutate into a chicken one day, but rather, the transition was so gradual that dinosaurs and birds just seem blend into each other on the family tree.”

When the sun breaks through for a moment, I catch a glint reflected in its beady eyes, which start to dance back and forth. No doubt this is a creature of keen senses and high intelligence, and it’s onto something. Maybe it can tell that I’m watching. Then, without warning, it yawns open its mouth and emits a high-pitched screech—an alarm to its compatriots, perhaps, or a mating call. Or maybe it’s a threat directed my way.
Right now is the golden age of dinosaur research. Somebody, somewhere around the world, is finding a new species of dinosaur now, on average, once a week. So that’s 50-some new species a year, and that’s not a new bone or a new skeleton, that’s a totally new type of dinosaur that we never knew existed before.Prior to listening to this book, my knowledge of dinosaurs was based primarily on a smattering of news reports. Thus I previously had the impression that the bird-dinosaur relationship was a debatable hypothesis. But evidence now available seems quite convincing.
The Liaoning fossils sealed the deal by verifying how many features are shared uniquely by birds and other theropods, not just feathers but also wishbones, three fingered hands that can fold against the body, and hundreds of other aspects of the skeleton. There are no other groups of animals, living or extinct, that share these things with birds or theropods. This must mean that birds came from theropods. Any other conclusion requires a whole lot of special pleading.Among the unique features shared by birds and dinosaurs is a respiratory system that provides highly efficient and light weight oxygen transfer system. No other species alive today has a respiratory system like this. To me this is the definitive proof of the relationship.
