MemberCompsognathusJul-09-2013 7:36 PM@Rex Fan -- Why do you believe Spino is smaller when there is a complete reconstruction of a Spinosaurus Aegypticus skeleton in Egypt that exceeds the size of Rex, not to mention every other discovered therapod?

MemberCompsognathusJul-09-2013 8:38 PMIt exceeds length and height yes, but in my opinion, not weight. Spinosaurus is, in my opinion, up to 56 ft long and 25 ft tall at the top of the sail. 6 ft longer and 2 ft taller than the max length and height for Rex. However, Spinosaurus seems more slender and not as heavily muscled as Tyrannosaurus. I give Spino a weight of 5-7 tons and Rex a weight of 7-10 tons. Spino is longer, but not heavier. It's like Diplodocus being longer than Brachiosaurus, but Brachio is heavier. Who's considered bigger? Brachio. Same goes for Spino and Rex in my opinion. Does that help? If not I can give more reasons on why I think that way.

MemberCompsognathusJul-10-2013 8:32 AMThose were all ones I had in mind. I wanted to do a few that most people don't really think of at first like Tyrannosaurus and Stegosaurus. The ones you gave are perfect honorable mentions though.

MemberCompsognathusJul-10-2013 9:11 AMIf you compare skeletons, Spino is longer and taller, yes. But add the sail, longer neck, longer skull, longer legs, and longer arms, and this makes for a predator larger than Rex. It has always appeared to me that Rex's smaller size is taken up mostly by body, while Spino's larger size is taken up mostly by limbs, sail, etc. But let us say that we have a the body of a Rex and a Spino laying at our feet. Both are missing the head, arms, legs, tail, and for Spino, the sail. I think that rather than bigger, Spino's body would be the same size as Rex's. But add the longer limbs of the Spino, and it makes it larger than Rex with limbs. The body size is the same. Spinosaurus was a sleek, muscled predator. I don't agree that Rex was bigger, but I agree that, [i]relative to the overall size of the dinosaur[/i], Rex was more body.
Take for example a short kid and a tall kid. The tall kid has everything the short kid has, except the neck is longer, the arms and legs are longer. The tall kid is considered bigger. Take away the [i]long[/i] limbs and replace with short, and the tall kid's body size will resemble the short kid's. Spino is the larger predator. (This is my opinion; anyone else feel free to back me up or dispute.)

MemberCompsognathusJul-10-2013 9:26 AMOr you could look at it like the tall kid is skinnier, say 130 lbs. The short kid could be stockier, say 140 lbs. Who weighs more? When scientists look at size, they go by weight. Tyrannosaurus seems more "stocky". Overall, more muscle and therefore, more weight. Long and lean is possible. So is short and heavy. In MY opinion, Spino is long and lean. Rex is short and heavy.

MemberCompsognathusJul-11-2013 3:33 PMHere's what I'm trying to say. I don't think Spino was lighter or leaner than Rex. I think the size of their bodies were the same, but Spino's limbs, skull, and neck were longer. Hence, a tall kid with the same body structure as the short kid. I don't think Rex was heavier.

MemberCompsognathusJul-11-2013 3:37 PMAnd I don't think Spino was heavier. I don't think we are going to convince each other one way or another. We've all got our own theories. I'm going to stick with mine and you can stick with yours :)

MemberCompsognathusJul-24-2013 4:01 PMA 50 ft Tyrannosaurus is heavier than 9 tons :). 9 tons is for the 12.3-meters long "Sue". A 15m/50 ft Tyrannosaurus is possibly 11-12 tons . So, if you're rigth about Tyrannosaurus size, Tyrannosaurus was comparable if not larger than Spinosaurus (although shorter).

MemberCompsognathusJul-24-2013 4:11 PMSpino is certainly the longest theropod. No doubt about that. Weight is hard to do though. For any dinosaur really. I think T-rex was heavier than Spino, but not as long.

MemberCompsognathusSep-06-2013 8:20 PMGood list! For my money though, I think a pachycephalosaur deserves some recognition. Stygimoloch or the classic name sake. Just for the unprecedented boney head structures and the on going mystery behind their purpose. Suchomimus came to mind too because of the crocodilian snout, but that also applies well to Spinosaurus who also has the more unique sail. Good call there. I also couldn't help but notice no sauropods. The weight and length alone make them pretty unique, not to mention the necks.
Dynamosaurus Imperiosus/ Raptorexxx 700
MemberCompsognathusSep-09-2013 4:10 PMhi im new here i know this seem strange but i cant start a discussion whenever i do it just leads to the discussion page and my discussion is not there
Dynamosaurus Imperiosus/ Raptorexxx 700
MemberCompsognathusSep-09-2013 5:04 PMtyrannosaurus rex meaured over 40 to 51ft long thanks for mentioning that and actually a 50 ft trex would probably weight around 13 tons
DinoFights
MemberCompsognathusSep-09-2013 5:27 PMNo known T. rex exceeded 43 feet, with Sue measuring 40 feet in axial skeleton length. Factor in discs and a tail tip, she's 41-42 feet.
Announcement Coming Soon
Prepare yourselves, DinoFans!

MemberCompsognathusSep-09-2013 5:49 PMI put my max sie estimates for these dinosaurs ;)
Keep in mind I did say that they were my estimates.
Raptorexxx, I see a 50 ft Rex weighing at least 9 tons, but 11-12 is not unreasonable(again, my estimates)

MemberCompsognathusOct-24-2013 3:38 PMSpinosaurus is the #1. It is much much bigger than T-rex, not including the sail. Kinda reminds me of an oversized, bloodthirsty Ouranasaurus.
Remind me to thank John for a lovely weekend.

MemberTyrannosaurus RexOct-24-2013 4:19 PMThis is bizarre. Nothing to do with size, just strangeness, or if you prefer it, uniqueness. It's a reasonable list, and Spino did make the top three.

MemberCompsognathusJan-08-2014 8:20 PMactually, the Guan-Long. it is not pretty weird. the early tyrannosaur is actually had long arm, the short arm of the tyrannosaur is developt at the early cretacoeous periode. and the Guan-Long lived in the mid Jurassic Period.

MemberCompsognathusJan-08-2014 8:32 PMYou're telling me this doesn't look a little weird?

MemberCompsognathusJan-10-2014 12:47 AMAcctually........ Not so! as all the past comments, Guan-Long and other Early Tyrannosaur Species do have feathers, the early species is using it as the display or warm their body, it seems those crest is also used for display. and the long arm, just like my comment.the small arm is developt at more lately stage.
