Do you like dinosaurs? I rather like dinosaurs. Lets start with A shall we? Great. A dinosaur that starts with A is the Ankylosaurus. Like me, you may have previously heard of the Ankylosaurus because it is "often considered the archetypal armored dinosaur" (Wikipedia, 2010).
The Ankylosaurus is noted for its big fuck off shell, which is believed to have protected it from enemies. This armour consisted of "massive knobs and plates", and yes I just included that bit to mention knobs. Besides its shell, it also had a big fuck off tail club. It is unknown if this was used in defence or in combat. Personally, I would use it both ways if I had a tail club, but maybe that's just me.
Surprisingly, no full skeleton of this wonderous beast has ever been found. But that doesn't mean they haven't been looking, no sir! The beast was named in 1908 by a chap called Barnum Brown who had found a partial skeleton in 1906. He also found at least two other partial skeletons and many other isolated bones, armor plates and teeth have been found over the years by others.
Sadly, Jurassic Park never returned the Ankylosaurus' phone calls and it is still waiting to become a big time movie star.
