Tea at Trianon: Are Birds Dinosaurs?

John Wilson Croker on Marie-Antoinette

"We have followed the history of Marie Antoinette with the greatest diligence and scrupulosity. We have lived in those times. We have talked with some of her friends and some of her enemies; we have read, certainly not all, but hundreds of the libels written against her; and we have, in short, examined her life with– if we may be allowed to say so of ourselves– something of the accuracy of contemporaries, the diligence of inquirers, and the impartiality of historians, all combined; and we feel it our duty to declare, in as a solemn a manner as literature admits of, our well-matured opinion that every reproach against the morals of the queen was a gross calumny– that she was, as we have said, one of the purest of human beings."

~from History of the Guillotine by John Wilson Croker, 1844

Edmund Burke on Marie-Antoinette

"It is now sixteen or seventeen years since I saw the queen of France, then dauphiness, at Versailles; and surely there never lighted on this orb, which she hardly seemed to touch, a more delightful vision. I saw her just above the horizon, decorating and cheering the elevated sphere she had just begun to move in, glittering like a morning star full of life and splendor and joy. Oh, what a revolution....Little did I dream that I should have lived to see such disasters fall upon her, in a nation of gallant men, in a nation of men of honor and of cavaliers! I thought ten thousand swords must have leaped from their scabbards, to avenge even a look which threatened her with insult. But the age of chivalry is gone; that of sophisters, economists, and calculators has succeeded...."

~Edmund Burke, October 1790

Are Birds Dinosaurs?

From Live Science:

What do sparrows, geese and owls have in common with a velociraptor or the mighty Tyrannosaurus rex? All can trace their origins to a bipedal, mostly meat-eating group of dinosaurs called theropods ("beast-footed") that first appeared around 231 million years ago, during the late Triassic Period.
The earliest birds shared much in common with their theropod relatives, including feathers and egg-laying. However, certain traits – such as sustained, powered flight – distinguished ancient birds from other theropods, and eventually came to define modern-bird lineage (even though not all modern birds fly).
Today, all non-avian dinosaurs are long extinct. But are birds still considered to be true dinosaurs
In a word: Yes.
"Birds are living dinosaurs, just as we are mammals," said Julia Clarke, a paleontologist studying the evolution of flight and a professor with the Department of Geological Sciences at the University of Texas at Austin.
In spite of the physical differences that distinguish all mammals from other species, every animal in that group — living and extinct — can trace certain anatomical characteristics to a common ancestor. And the same is true for birds, Clarke told Live Science.
"They're firmly nested in that one part of the dinosaur tree," she said. "All of the species of birds we have today are descendants of one lineage of dinosaur: the theropod dinosaurs." (Read more.)
