That reminds me of this other pic I saw, in which Carnos used their arms to fly.
I wish I could find it again ...

I heard that Parasaurolophus cyrtocristatus is the biggest Parasaurolophus species. Is this right?

Nope. Tubicen's the biggest.

Quite the opposite, actually. P. cyrtocristatus is the smallest (but youngest geologically) species of Parasaurolophus.

Incorrect.

P. cyrtocristatus is neither the oldest OR youngest species. P. tubicen lived a million years AFTER it, and my research tells me that P. walkeri is in fact the oldest.

As of last year, Charonosaurus can most likely be classified as another Parasaurolophus species, meaning the newly reclassified Parasaurolophus jiayinensis would be the youngest (living until the very end of the Cretaceous). UNLESS the lambeosaurine material at Hell Creek turns out to be Parasaurolophus too, in which case it survived until the end on TWO continents.

my apologies, I read the Wikipedia article wrong. :P You are right. However I really don't think you can call Charonosaurus a species of Parasaurolophus. Even if they are similar, they are still separated by seven million years. I find it hard to believe that they can stay similar enough for that long to be in the same genus, especially on a different continent.

I don't see why its impossible tough, i mean, pachyrhinosaurus stood there for nearly twice as long and some genuses like Alectrosaurus are also very long lived, so why not parasaurolophus?

Tough i'm cautious with lumping species and genera mainly because most of the time we just don't have enough to tell.

Pachyrhinosaurus as a genus only existed for four million years. Lumping Charonosaurus with Parasaurolophus would have the genus existing for ten million years.

As for Alectrosaurus, I seriously have my doubts that it lasted so long, at least as one species. Its environment was certainly not stable for nine million years. And even then, it's living in a very small range- not on another continent.

Mosasaurus was a real thing, but it did NOT look or behave like the one in Jurassic World (actually none of the JW animals are like the real things, as Wu said in the movie), and it was NOT a dinosaur, but a sea reptile closer to lizards and snakes.

Also, I have to ask you to use proper grammar, it makes your sentences easier to read and understand.

Flish: we still got things like Struthiomimus and maybe Troodon, which were found from Dinosaur Park to Hell Creek with different species. Although those were probably more adaptable than a huge herbivore.

And avoids me having semi heart attacks, too.

On topic, are any Pterosaurs (other than Tapejarids) thought to have been at least partly herbivorous?

BTW I'm pretty sure MrRabbid was joking (though that doesn't exactly mean the post hurt my eyes any less, even if that was the point).
