The correct answer is, of course, Ankylosaurus.


    1. I saw one of those club tails in the Museum of Natural History once.  It was as big as my torso.  Definitely pretty amazing.  Wish they’d had a whole specimen, but hard to bitch when they had a tyrannosaurus and several triceratopseseses.

  1. Actually, I think Ankylosaurus and Dimetrodon are locked in an eternal battle for the title of best dinosaur. This is, of course, the best dinosaur fight.

    1. Except Dimetrodon is NOT a dinosaur; it’s actually more closely related to mammals, including humans, than archisaurs, which include birds and non-avian dinosaurs.. 
      You might as well call a woolly mammoth a dinosaur…

      1. Dammit, I knew somebody was going to go there. Fine. I will also call a woolly mammoth a dinosaur. And dimetrodon and ankylosaurus are still tied for most awesome.

        My plastic dinosaurs when I was a kid always had dimetrodon. I am fine with dinosaurs having feathers now, but DON’T MAKE ME CHANGE MY TIED-FOR-FAVORITE DINOSAUR ON A TECHNICALITY!

        1. I will also call a woolly mammoth a dinosaur.

          God dammit, this is what Power Rangers has done to my generation.

          That’s when the show lost me: halfway through the first episode, when Zordon referred to “the Sabretooth Tiger Dinosaur and the Woolly Mamoth Dinosaur”.

        2. While I absolutely love the Dimetrodons, I have come to peace with the fact that they indeed are not dinosaurs.  Going extinct 70 Million years before the first (or next) dinosaurs showed up on the scene means they aren’t really dinosaurs.  If we humans go extinct tomorrow, and in 70 Million years salamanders have evolved into things similar in appearance to humans, you wouldn’t call them primates would you?

          Just a little exposition.  I think the deep time makes the perception of the key differences hard.  They all existed (shoutout to Sagan) billions and billions and billions of (let me do the unit math) picoseconds ago (160MYA ~ 10^27 picoseconds ~ (10^9)^3).  And the fact that Dimetrodons have been lumped in with dinosaurs in the popular media for around 100 years.

  2. Stegosaurus all the way!

    Although my 2 year-old has an obsession with Pachycephalosaurus, of all dinos she could go for, because it’s wearing a tuque.

      1. Nope.  Triceratops was the first name and therefore the canonical name.  Even if it IS decided conclusively that the Torosaurus is the adult form of the same animal (and there’s currently some debate on that).

    1. If you’re willing to cast your faith out further than absolute reason, perhaps Amphicoelias Fragillimus is the dinosaur for you.

      Only one specimen found and described in 1877.  The find included two vertebrae and a femur.  It’s all gone missing now, and all that remains are the descriptions and illustrations made by the discoverer, Edward Drinker Cope.

      So there’s no evidence other than a described, but lost (or never existed) fossil.

      It would have been twice as long as Argentinosaurus based on the Diplodocus scaling models, and would have weighed 122 Metric Tonnes.

      But I’d say Argentinosaurus is definitely the largest known dinosaur that is proven to have existed.

  3. having been to Dinosaur, CO, I can vouch for the fact that it is not, in point of fact, the best dinosaur

  4. My favorite dinosaur has to be the Chicken. Just look at their feet when they’re walking! I just read parts of the Wikipedia article on chickens, quite fascinating. Plus they taste like chicken.


    Edit: The Emperor Penguin is also cool. But I don’t know what that tastes like.

  5. Actually, I don’t think Siri is far off. Dinosaur National Monument is pretty darned cool. First, there’s the desert environment, with rock outcroppings carrying some really neat cliff paintings. Then there’s the museum, where they have left a fossil bed exposed/cleaned but in situ so you can see what a rich cache of bones actually looks like in the field. Then there’s sometimes news about the latest discovery — this is still an active research area. Finally, there’s the risk/hope that you might discover a fossil yourself while wandering the grounds. (If you do, they ask you to PLEASE leave it exactly where you found it and report it to them — context is important data and might point them toward further discoveries.)

    And to top it off, they have a technocolor Stegosaurus.  No, they don’t know that dinosaurs were brightly colored and patterned — but many critters are (consider birds, the “surviving dinosaurs” — and reptile scales as well), and there’s certainly no reason they had to be boring. It’s not as if an adult stegosaur spent a lot of time hiding…..

    1.  I had an awesome Grade 8 Science teacher, trained as a geologist, who made us colour all of the handouts she gave us. If we were colouring, we were looking at the pictures, she reasoned. When we did dinosaurs, I went nuts with the colours, and argued that I hadn’t used any colours that could not be found on a modern reptile. “You have a point, but I’m pretty sure they didn’t look like THAT.” she said.  Decades later, science is proving me right.

  6. I believe the website http://www.thebestdinosaur.com/ gives us the clear definitive answer to the question of which is the best dinosaur.
