Summary: A small dinosaur the size of a kangaroo has been under study since it was discovered in Chile. - named Chilesaurus. Because it resembles a velociraptor, initial assessment placed it as a relative of therapod. After study began it became obvious this dinosaur is a vegetarian. Scientists started finding features of ornithischia, but also found features of therapod. After careful observation the scientists have come to the conclusion that Chilesaurus is a hybrid of therapod and ornithischia.

Alright I admit I'm not up to speed on my dinosaur types, but I hope the people that are find this interesting...
Yes, must be a missing link, because I don't see convergent evolution making a hybrid between the two dinosaur orders. Unless it was really trans ... it was a T-Rex trapped in the body of a Stegasaurus ;-)
Chilesaurus ... probably had an evolutionary advantage, its flesh was too spicy for most predators ;-)
The way I understand it, every fossil out there is a 'missing link', no?
Not a hybrid. Just as among the original plant-eaters, some became carnivores, it can go the other way too. Hybrid implies a species meld.

Like all people are equal, but some are more equal than others ... all fossils are missing links, but some are more missing that others. Some aren't missing at all ... coelacanths.
It may be a "hybrid" of the characteristics of the two dinos, but they didn't make whoopee.

No, 2 planteaters don't suddenly make a carnivore. But at least one carnivore became a vegetarian.
TUESDAY, Aug. 15, 2017 (HealthDay News) -- A odd-looking vegetarian dinosaur named Chilesaurus could be the "missing link" between the plant eaters and meat eaters of its time, researchers report.
The dinosaur, named after Chile, the country of its discovery, has mystified scientists. For instance, its head looks like that of a carnivore, but instead of sharp teeth it had the flat teeth that are typically used to chew plants.

Yeah, but not by fucking a herbivore. That's what "hybrid" means. I wonder if the original paper used that term?

You are using "hybrid" wrongly. Please stop.

Please give me the official definition.

A crossbreed of 2 related species of plants or animals that produce viable offspring. The offspring themselves may or may not be fertile themselves but must at least be able to exist on their own. A Liger is a hybrid of a lion and tiger. The 2 cats are closely-enough related to produce a viable offspring thought they would generally not mate in the wild.
Some genetic similarity is required. You can't mate (at least not yet - but genetics advance every year) a cow and a camel, their common ancestry is too far apart You can't mate any herbivore and carnivore I can think of. THEIR ancestry is WAY far apart.
If you are thinking about humans, all humans are the same species and easily reproduce at will (and boy do they ever! If you are thinking about dinosaurs, you can't have a tyranno-brontosaurus. Their lines diverged about 220 million years ago.
Does that help?
The OP said "hybrid". I was saying it isn't a hybrid. Problem?

Potentially. Except the ones that go extinct before speciating. A missing link (aka transitional) is always recognized in hindsight.
The term missing link bugs me because it's presented as this huge problem for evolution. But for every "missing" link that is found, you get two new "missing links". And it's impossible to ever have complete records. Fossils are snapshots in time and some people want to see the whole reel (which doesn't exist) before declaring that two photos could possibly be related. It's idiotic.

To have no missing links we just have to line up the skeletons of every single animal and plant that ever lived. Simple.
A missing link!? Don't tell Ken Ham, he may have a stroke!
On the other hand, go ahead and tell him.

intentional misuse of the word hybrid... the correct word has escaped my mind. They are related on the classification chart.

more likely T-rex ate the Stegasaurus and then through some unexplained act of digestion the Stegasuarus got T-rex pregnant ;-) accidental hybrid
if spicy flesh was an advantage long enough for humans to show up Chilisaurus advantage would have been quickly changed to a disadvantage

Well, aside from the fact that no Stegasauros ever met a Tyrannysauros by about 100MY... OK...

I love that line from the creationists. Someday I will get to ask one of them that about Adam and Eve or Noah's Flood. "Were You There"?

Jurassic Park.
