No.
Short answer: No
Long answer: Yes
No.
However, as with so many yes/no questions, the proper answer is “It depends.”
Shel Silverstein sez, “What am I, chopped liver?”
This is the best answer.
And to expand on the second (long) answer:
I would say, “Technically, yes…because all living birds are technically dinosaurs and there is no way to define what a dinosaur is (that includes all of the animals commonly referred to as “dinosaurs”) that does not also include birds (other than artificial constructs like “non-avian dinosaurs”).”
If anyone is curious, there are two orders of dinosaurs, mainly distinguished by their hip joints:
-
Ornithischian dinosaurs, like Triceratops or Stegosaurus.
-
Saurischian dinosaurs, which are further subdivided into two suborders:
- Sauropodomorph dinosaurs, like Diplodocus, Apatosaurus, or the familiar Brontosaurus (although the status of the last as a distinct genus is uncertain).
- Theropod dinosaurs, which includes Tyrannosaurus rex, Velociraptor, and all living birds.
Birds are therefore much more closely related to T. rex (indisputably a dinosaur in the popular imagination), than either are to dinosaurs in the other categories (which are also indisputably considered to be “dinosaurs”.)
Ergo, birds are dinosaurs.
I’ve been kind of amused – and a little confused – that ornithischian (“bird-hipped”) dinosaurs aren’t the ancestors of modern birds.
It’s technically true that humans and birds live at the same time and birds are dinosaurs.
It’s also true that technically true answers allow facts to be yanked entirely out of context to give responses that are opposite to the larger meaning.
With no context at all given in the OP, no answer can be satisfactorily given. Might as well say yes because you believe that an ancient now vanished race of humans lived 100,000,000 years ago.
But does that follow? Please excuse my ignorance, genuine question…the indisputable relationship / lineage between dinos and birds doesn’t necessarily make birds dinosaurs, does it? We all descended from single cell life, right? That doesn’t make us amoebas.
Please be kind in your response if this is a dumb question. 
Lineage is indeed part of it, but not the whole story.
It’s the fact that if you want to include a group (technically a “clade”) of animals as diverse as Tyrannosaurus rex, Triceratops, and Apatosaurus in the same category (i.e. “dinosaurs”), then the group necessarily and logically must also include modern birds.
Modern birds are not only closer to other theropods (like T. rex) physically, genetically, and evolutionarily, but are also closer temporally to T. rex (65 million years) than T. rex itself was to dinosaurs like Stegosaurus (which died out about 145 million years ago).
And if you get into the science of cladistics, you learn that a clade is a group of organisms that is composed of a common ancestor and all of its descendants. So since dinosaurs are today considered to be members of the clade Dinosauria, modern birds are also members.
(And incidentally, if you want to make a clade that includes all amoebas, you will find yourself including all eukaryotic organisms, because amoeboid cells are found in all major lineages of eukaryotic organisms. And yes, humans fall into that clade as well, because humans are eukaryotes. With that said, amoebas do not otherwise fall into a single defined taxonomic group.)
That’s why I call such “factual” questions functionally indistinguishable from riddles. In both cases, you basically have to guess what the questioner means before you know what the answer “should” be.
Thank you, very helpful.
Agree. If this question was being asked in good faith the OP could have easily specified a kind of dinosaur often depicted with cave men in fiction like a Tyrannosaurus rex.
Hey, it’s Jersey. I wouldn’t call it “living”!
Did humans live alongside dinosaurs? Define your terms.
Is Dr. Deth’s ‘like a poll’ worth anything? No.
no, our ancestors were basically tree shrews at the time.
Maybe not. There have been some fun and entertaining films (and one great cartoon) that showed “cavemen” and dinos co-existing. Some not well educated people could well accept that. Only 20% of Americans are Bible Literalists.
Not dumb at all. The current consensus among Scientists is that Birds are Dinosaurs . There are a reasonable number of holdouts who will only say "Birds are descended from Dinosaurs
or “Birds and Dinosaurs are closely related”.
Good answer.
I am doubtful if that is why the poll was originally done, but certainly it has been used many times to show just that.
Polls asking these sorts of questions are meant for headlines, not deep insight. The fact that it is a question in a poll provides all the context needed: no factual knowledge is required, just an average understanding of common American English usage. No good poll would put definitions into a question - hey, we really are asking about Fred Flintstone’s Dino, not recent cladistics. But a really good poll wouldn’t ask the question in the first place. Nevertheless, the best takeaway from the 41% answering “yes” is that around 40% of Americans think that it is correct answer. It’s not a trick question; nobody should delve beneath the surface. Surface is all it had. Stripping away the surface just leaves a hole that smartasses like us can fill. But by doing so we’re taking away information rather than adding it.
It was done by the California Academy of Sciences back in 2008- and yes, even back then Birds were Dinos.
Other questions/results were:
. According to the national survey commissioned by the California Academy of Sciences:
- Only 53% of adults know how long it takes for the Earth to revolve around the Sun.
- Only 59% of adults know that the earliest humans and dinosaurs did not live at the same time.
- Only 47% of adults can roughly approximate the percent of the Earth’s surface that is covered with water.*
- Only 21% of adults answered all three questions correctl.
It seems they allowed some leeway on the two “math” questions- any answer between 65 and 75% was accepted as right for oceans. I do not know about how long it takes for the Earth to revolve around the Sun. Since the answer of course was not exactly 365 days. But I was reading the bit about Humans and dinos in a book, and yeah, they yucked it up about how stupid Americans were.
Yes. It’s like “If a tree falls in a forest, does it make a sound?”
If you answer no, then the wise guy says “Wrong - the falling tree would cause air to vibrate and that’s what sound is!”
If you answer yes, then the wisenheimer says “Wrong - there’s no one around to have the internal mental state called ‘sound.’”
Providing a yes or no answer is a sucker’s game.
It is confusing, but relates to the fact that the group of dinosaurs was named before the true relationship between dinosaurs and birds was understood, so ‘ornithischian’ dinosaurs got that name based on a superficial similarity to birds, by people who didn’t know that other dinosaurs had a cladistic relationship with birds (it’s like how the word “meteor” and “meteorology” are both derived from a term meaning “atmospheric phenomenon” but they’ve become specialized to mean rather different things).
Good answer!
