A few articles about the colossal Ammonite Parapuzosia seppenradensis with an estimated shell width of 2.55 to 3.5 metres and a minimum weight of around a ton and a half this great cephalopod was slighty bigger than the ones you can find on the beach.
A nice article on Giganotosaurus carolinii - currently the closest rival to Tyrannosaurus rex as far as carnivorous dinosaur body mass is concerned (now that Spinosaurus has been found to weigh a 'mere' 7 tons).
Whenever a new species of enormous theropod is discovered it gets overhyped by the media as being bigger than rex. But every single time this has eventually proven to be not the case (so far).
Acrocanthosaurus, Giganotosaurus, Carcharadontosaurus, Mapusaurus, Tyrannotitan and Spinosaurus.
Rex was heavier than all of the leading contenders (if very slightly shorter than a couple) although it is quite close and I suspect that rex and the others approached the biomechanical limits for a terrestrial predator.
However rex was more heavily built, probably faster, had a relatively huge brain, more advanced binocular vision, bigger teeth and a far more powerful bite when compared to the others.
Still the King (or Queen as the females were probably larger)?
The creature on the right is a late origin fossil trilobite from the early Carboniferous period and it was a surprise Christmas present for me. It's next to a 15cm/6ins ruler for scale with my best ammonite fossil on the other side.

And some superb size charts also featuring the gigantic Orthoconic cephalopod genus Cameroceras in a thread on Tonmo.

A few articles on that massive beast are here.

It is also one of the few giant theropods to be known from an almost complete skeleton.

Some excellent reconstructions of which the first is my favourite because of the plumage.

This one is almost impressionist - very atmospheric In my opinion.

I'd love to go see Sue in Chicago.
What I love about the tyrannosaur family is how varied and prolific it is. One of the most interesting of all dinosaur families imo.
Better than binary any day!

Indeed it is.
And just for you here is some Tyrannosaurus rex porn - sadly no huge 70's tashes but there is a link to some cheesy music to go with the illustration!

not adding much, but a simple review. Loved the comment "In the first 500,000 years [after the die-off], the animals were not happy"
and one on pyritisation of fossils

Every one of these species is absolutely fascinating in their own right - look them all up if you are at all interested in these advanced theropods.

In my eyes - yes.

I like it.
Though I don't post much in this thread, I do like dipping in occasionally to read new articles.

Thanks Dave.
A busy to post much over the last day or so for obvious reasons.
Anyway in true Tyrannosaur (but not too festive) style - Happy Christmas to anyone who enjoys reading this thread.

Father Christmas looks suspiciously like Charles Darwin here.

Though when Darwin came up with his theory he didn't have a beard.
True - but Father Christmas does!

I do love Tyrannosaurus rex - and this beautiful black and white reconstruction of an adorable little baby shows why.

At the other end of the scale another nice photo showing the sheer size of the monstrous, 12.3 metres long, 10 ton + Sue.

The creature on the right is a late origin fossil trilobite from the early Carboniferous period and it was a surprise Christmas present for me. It's next to a 15cm/6ins ruler for scale with my best ammonite fossil on the other side.
More about the long lasting trilobites here http://en.wikipedia.org/wiki/Trilobite and there's an evolutionary diagram here http://www.trilobites.info/triloclass2009.png.
