Thank you for the set, Azrael!

It's still my favorite series today, I think.

You can't group all large Theropods together ;) Tyrannosaurids belonged to Coelurosaurs and as such are more related to Ornithomimosaurs, Compsognathids and stuff than to other large Theropods such as Allosaurids.
Abelisaurids are late-surviving Ceratosaurs.

Evolving creatures from earth.

Well I like planet dinosaur as series.

But I liked that movie about the tarbosaurus too even if some things weren't accurate

I've been convinced that tyrannosaurs probably had feathers, but I doubt other large theropods had many feathers.

Yeah, I'm doubtful on that too ;) We don't know about Sciurimimus for the moment. However, since this recent discovery about dinosaur scales being modified feathers, I rather think the ancestors of Dinosaurs were feathered and these feathers then turned to quills and Dinosaurian scales ;) But for the moment, it's up to the artist. And I personally prefer great fluffyballs.

If you take the text in that picture out of context, It's actually passable, but the illustration is so intriguingly outdated it's hilarious. Ah yes, Spinosaurus, A creature butchered by some of the most annoying people on Earth. Now, I will say this: I enjoyed the antics of the JPIII Spino, because of how ludicrously overboard Jack went on making Spino look like some sort of ultimate badass of prehistoric destruction, but the real Spino is a lot more interesting.

The 4 ton estimate for Edmontosaurus annoys me. How can a hadrosaur the same length as T. rex weigh nearly 3 tons less, yet it's bulkier and wider than the theropod?

The simple answer is theropod bias, my friend. ;)

First of all, they have a different body build, second, T.rex's skull alone weighs a lot. Not all hadrosaurs are estimated to be lightweights aswell, for example for Saurolophus angustirostris from Asia I've seen estimates going as high as 7 tons.

Also... T.rex was much more bulky than Edmontosaurus. Among dinosaurs it was what we would consider a bodybuilder. Strong bones and lots of muscles won't give you less weight. Also, making T.rex purposely havier than Edmontosaurus isn't a bias towards the theropods. Because it makes the good old rexy less and less capable of keeping up the pace with its prey.

While T. rex was indeed a very bulky theropod, hadrosaurs were no slouches, either:

Granted, the T. rex is an "average" sized individual, and the Edmontosaurus is on the large end for its kind, but you get the idea.

And this proves... what exactly? 4 ton estimates are given to the animals with maximum size estimate 12 m, while the top weight estimates for T.rex were done for animals like Sue. From what I recall top weight estimates for the 13 or so meters long Edmontosaurus were balancing around 5-6 tons. And again - rex's skull alone weighs much more than Edmontosaurus' one, add the muscle mass behind those jaws into the account, plus powerful neck to support it. When you look at Edmontosaurus and its skeleton, you can see that it, in fact, was more lightly built.

Most of the ones I find for Edmontosaurus of that size are just 4 tons, and I'm fine with 6 tons for an animal of that size (though I'd prefer something closer to 7 tons).

The fact that I can't Google pterosaurs without coming across David Peters skeletals!
