Dynamosaurus Imperiosus/ Raptorexxx 700
MemberCompsognathusOct-04-2013 10:56 AMhi i know i have been pissing people off by that top 10 bite force thing but as i said some of those i studied really well including tyrannosaurus,torvosaurus,triceratops. but i wanted to make it up!
but i have had a theory that dinosaurs were probably much more diverse in size for example: researchers have found a ceratopsian footprint that measured 80 cm wide which would make the animal between 12.6 to 14.4 m long! also dinosaurs like ceratopsians, ornithopods, and sauropods have been discovered to have cartilage that would have made them longr and taller by 10 %
estimates:
triceratops : l: 9.9 m h. 3.6 m
shantungosaurus: l: 17.6 m h: 6.6 m
argentinosaurus: l: 33-39.6 m h: 13.2-18.6 m
and one thing people don't notice is that young animals usually die a lot more than adults do and that there are specimens that are larger than others and i calculate that the biggest of the following species estimates are:
giganotosaurus: 49 ft long
tyrannosaurus: 48 ft long
spinosaurus: 62 ft long
theory 2:
another theory is that by 65 million years ago there was a land bridge that connected Asia to north America as evidenced by troodon teeth found in siberia and the possibilty that dinosaurs such as albertosaurus, gorgosaurus, pachycephalosaurus, and maybe even tyrannosaurus lived in such places as alaska and there bones sunk as the ocean grew larger (explaining why alaskan dinosaur remains are so close to the arctic sea).
theory 3:
in this theory i think that tyrannosaurs were actually pretty good swimmers because A LOT of tyrannosaur remains have been discovered in what was swampy areas, and most creatures that live in swamps these days are pretty good swimmers and the tail of tyrannosaurus was actually pretty stiff which may have allowed the sideways movement that crocodiles swim with today
hope you like it please share your thoughts!

MemberCompsognathusOct-04-2013 11:19 AMI actually like your theories. Most of them at least. I agree with Giganotosaurus being 50 feet long, but where did you get the 48 foot T. rex? Most of our adults have been only 42 feet, I'm pretty sure that Sue is only 43. I would understand a few foot difference, but a 5-6 foot? That's a bit crazy to me. I understand the land bridge thing. It makes sense. Tarbosaurus/Z-tyrannus could have evolved from dinosaurs like Alertosaurus and Daspletosaurus. There is pretty much no evidence of tyrannosaurs from middle Cretaceous Mongolia, so I like that.

MemberCompsognathusOct-04-2013 11:26 AMOK, so: 1. The 80cm wide triceratops foot belongs to a new species, named Ceratopsipes (that's what they think), and it's possible some animals died younger, so maybe you're right.
2. Hmmm... it's possible...
3. I think this too. They could be good swimmers.

MemberCompsognathusOct-04-2013 6:29 PM1. I obviously disagree with your size estimates. Most reputable scientists think that the cartilage length is oversized. Yeah, the huge footprints are real and, if anything, caved in around the edges and are smaller than they would be in life. Ceratopsipes seems valid, albeit as an ichnotaxon.
2. That seems absolutely plausible. Troodon in Alaska seem to have filled a macrophagous niche, being larger than a Troodon further south.
3. That depends. If you take the porker rex that weighs 9+ t, it would be too fat and inflexible to move. However, normal Tyranno may be able to.
Also @ Deltadromeus, actually most adults are 37-38 feet, with a few breaking 39. Sue is a tiny bit over 40 feet in axial skeleton length and would be only 39 feet without a hypothetical disk enlargement. She is 42 feet by high estimates.
And just to point out something and be annoying, Zhuchengtyrannus is oversized. It was actually only Daspletosaurus sized and thus your theory is more plausible.

MemberTyrannosaurus RexOct-05-2013 6:48 AMInteresting theory. I think Rex Fan would agree with the 48 foot Rex idea. Hopefully he gets back from his vacation today or tomorrow and we find out.

MemberCompsognathusOct-05-2013 6:54 AMI think too a 48 foot Tyrannosaurus is plausible.

MemberTyrannosaurus RexOct-05-2013 6:57 AMI could see up to 45 feet personally.

MemberCompsognathusOct-05-2013 6:57 PMWell, Rex Fan is back ;)
I give Tyrannosaurus rex an average size estimate of 40-43 ft long and 7-8 tons. But a large, old adult, in my opinion, could get to 45-50 ft in total body length and weigh over 9-11 tons, maybe more depending on the muscle mass. As we all know, I put Giganotosaurus at 40-43 ft long and 6-7.5 tons on the average with a max size of 46 ft and 8-8.5 tons. Spinosaurus, in my opinion, averages 46-50 ft in length and 5-6 tons in weight with 56 ft in length and 7-7.5 tons as the max. All three are still deadly, gigantic predators and I would not want to run into any of them.

You're second theory is possible and I agree with your third theory.

MemberAllosaurusFeb-20-2014 6:20 PMAbout Tyrannosaurus swimming, it could using its legs and tail, plus holding its top half above the surface, but it probably could only swim in shallow water.
