Perhaps. If Rex was more solitary than Giga, then that just reinforces the theory that Rex was a better one on one fighter. While I was examining the Rex skull up close(they had 2 separate skulls that were unattached to the skeleton), I was amazed to see how powerful it was. The structure of it really showed how powerful it's bite would have been. Truly amazing.

It is very obvious that T. rex had thicker teeth. Railroad spike vs huge 8 Inch knife. The railroad spike is thicker for sure. Ten feet longer and only a half a ton to make up for is a bit silly. Based on your estimates Rex Fan, a fourty foot Giganotosaurus is about two tons per ten feet. Add another ten feet, and it will gain at least a ton. But yes MrHappy, in a one on one battle, T. rex will win around 65% of the time. Don't underestimate Giganotosaurus, it has large competitors too. Mapusaurus, 43-46 feet long, Tyrannotitian, 40 feet long, more robust. Ekrixinatosaurus, 35 feet long, six plus tons. A lone Giganotosaurus has got to be much stronger than a Giganotosaurus in a pack, otherwise, it will die.

That would have been funny. I meant that Rex would have been solitary sometimes, more than Giga for the most part.

It's likely that T-rex was also a pack hunter. Delta- The Giga was taller than the Rex by less than a foot at the hip. There was very little difference in height, just like length. One thing I liked was that they had a Compy standing next to the Giga. One of the smallest predatory dinosaurs next to one of the biggest, haha

Great. Storm is a T. rex, he can look after himself.

Their all good.

That means Giganotosaurus was already taller than rex at only fourty feet! Using my theories, I have made a Giganotosaurus weight table: 40 ft=8 t 45 ft= 8.45 t 50 ft= 9 With increasing increments each time we go up in length. I didn't do one for T. rex because I don't think it gets past fourty fourty 2 feet.

That's pretty cool. I figured Rex's teeth would at least be thicker than Giga's. too bad they didn't have a Spino skeleton. I think Rex would be heavier pound for pound than even a full grown Giga because of the extra ribs, and heavier bones. I think if it were 1 vs 1, Rex would beat Giga because it was more equipped for combat, and Rex likely did a lot of solitary fighting, while Giga lived in packs.

Thanks. Glad you liked this one.

I good chapter again. Now to find out who's territory he's in (I have a guess though).

Giga's legs were actually not much longer than Rex's. The Rex also had thicker and heavier leg bones, not to mention extra ribs which would add a little weight. It's stronger and more robust skull would add some weight as well. It was awesome to see two of the largest terrestrial predators ever in the same place. MrHappy, you'll like this. They had an Albertosaurus there too. It measured roughly 24 ft, give or take a foot. I did do my best to get the lengths and weights as accurate as possible.

Nice. Welcome back. I hope you had a good trip. Now for the paleontology. It is clear that T. rex is heavier ppf (pound per foot) but if we use the factor of having Giganotosaurus at 45-50 feet long, that half ton difference will disappear, and replaced by the Giganotosaurus's half ton. I have to remember that the length weight correlation is not you are ten pounds at three feet and twenty pounds at six feet. The length adds extra bone, and also a longer torso, which is most of the weight. The tail also lengthens and becomes heavier. So it is more fourty pounds at side feet instead of just twenty. I'm stating my opinion here, and I'm not criticising. I accually must say, good job. It sounds like a bit of work. Covered up by the amazement of seeing the fossils of some of the biggest theropods to ever live. Which for some reason reminds me, the legs will also be porprotionatly heavier in longer dinosaurs, even if the body build is exactly the same as something half as long. I'll be right back. I'm going to go do some math on Giganotosaurus.

They both had really long teeth, that's for sure. The Rex's were slightly longer and twice as thick at least. The Giga's were thin, but sharper than the Rex's. They were definitely for slicing while the Rex's were perfect for crushing.

That's pretty cool that they had a Rex and Giga skeleton. How much of a difference was there in the teeth?

No idea, but this doesn't really require a full topic to be started. Next time, try using the PM system, or post a blurb on the Status Board. We want to keep topics for related discussions only.

ok

Can't wait, I signed up for the FBR website too.

It's not even 3 in the afternoon yet. I think most people get home from vacations late at night (10-11ish at night). So don't worry yet, he did post yesterday, probably using museum Wi-Fi. He is probably still on the road, or resting after driving for who knows how long. I went on vacation to Tennessee last December, and we made the 16 hour trip in one go, so don't worry about it.

I think Das is like a 30 foot long tank with an attitude issue.

I think that they are all the time hunters, but will not pass up a good dead hadrosaur. In my opinion, they lived in a family pack. The teenager T. rexes slowly drift away from the pack as they get older, until becoming solitary.

The way i see it, T. rex was probably a giant Spotted Hyena. A primary hunter with a bone crushing bite. I think it would have been social like a hyena but not always a pack hunter. I also think it could have been a good scavenger when big enough to throw its weight around but it would have primarily been a hunter of hadrosaurs by ambush and an efficient one at that.

WOOOOOOOOOOOOOO! YEAH! I BEEN WAITING FOR THIS MY WHOLE LIFE !

Pretty sure that if indeed a pack hunter, it would be a family group consisting of the alpha male and female, sub adults, and chicks. The sub-adults would likely be female, while the male sub-adults would be driven away from the pack. The sub-adults would likely chase the prey to the adults, who then killed it.

first i see i hope t-rex , but now i hope spinosaurus

pretty nice site you got there paleo.... I dont think I have the patience to categorize every single dinosaur or the highlighted ones from each period

Speaking of websites, check out my unfinished website: alldinosallthetime.weebly.com

Yes, That reminds me i should probably get on that

Can't wait for 4 or the Lio vs Meg!

Das was far more powerful than Gorgo. Even though Gorgo is faster and more agile, Das has pure brute force.

Good fight. I liked it.

That's a sub machine gun (an UZI to be exact) Makaveli.

I thought Velociraptor would win because it was riding a shark with a machine gun and some dynamite lol Good fight though.

I think you might have to message one of the staff about deleting it.

Nice fight. Loved the Velociraptor picture. I thought that that Velociraptor was going to win because it had been on its own for a while and would be more experienced. Nice twist with calling for help.

I always wished that JP4 would have carnotaurus, ceratosaurus, carchorodontosaurus.

Sorry, I accidentally touch start discussion without finishing my post. Please delete this...

Cool, but not really forgotten. I've seen it in many children's dinosaur books

Cool. Go Velociraptor!!

I agree. Eric has the experience and he doesn't have anyone getting in his way. He'd survive the longest.

Haha, exactly my point! :)
