Comparison of the Big 4 ( Re-Do )

Well most of you know that I already did this once, but after some new research I have done I have found that there are some major flaws in my previous topic.  I wanted to share this new information with you! Most of you will find really interesting.

 Carcharodontosaurus Saharicus-Iguedensis:

 From a public standpoint Carcharodontosaurus is generally accepted to range between 12-14 m and 6-14 tons. But from a scientific standpoint it is something pretty different as the largest specimen (fragmentary) we have for C. Saharicus (SGM-Din 1) is about 13.6 m ( 44 ft ) weighs from about 2-9.2 tons. And don’t get me wrong that is by no way a small animal in fact it is one of the largest on the list. It was once thought to have possessed the largest Theropod skull of all time (a record held by its relative also on the list Giganotosaurus) but it is now thought to have a 1.57 m skull in the largest specimen. The second species, C. Iguedensis is thought to be as big as C. Saharicus’s Type specimen at 11.5-12 m (35-39 ft ) and 5.8-7.1 tons.

 One of the reasons I love this impressive beast is that: Carcharodontosaurus has some of the most underrated bites of all dinosaurs. It wasn’t built to crush bone like one of our coming contestants, after some research and A LOT of comparison to modern day animals I have come to the conclusion that Carcharodontosaurus’s teeth will allow it to kill with only one bite. You see, its teeth are designed to let you bleed to death rather than anything else, so in a way it only takes 1 bite from this beast to give a death sentence to anything it chooses.

So my final measurements (maximum) are:

Length: 13.95 m (45.9 ft)

Weight: 10.25 tons

Hip Height: 4.2 m (13.8 ft)

Giganotosaurus Carolinii:

The second Carcharodontosaur on this list Giganotosaurus is generally accepted to be 15 m (50 ft) long by the public, something I find quite irritating as we only actually have 2 specimens, the type specimen (MUCPv-Ch1) which measures a quiet average 12.3 m and the other Extremely fragmentary specimen (MUCPv-95) which probably measured around 13.2-13.7 m (43.5-45 ft) and 7.2-8.7 tons, not the 15 m and 9-13 tons most people thought as the specimen is only 8% larger. But like Carcharodontosaurus I am not saying that this is by any way a small animal, I am just saying that there is some flaws in some people’s estimations and measurements. It was once thought to have a 1.95 m (6.5 ft) skull which relatively would be extremely strange, but it still does however have the largest Therapod skull at 1.6-1.7 m (5.5-5.8 ft).

Even though they are similar Carcharodontosaurus Giganotosaurus’s biting techniques are slightly different it won’t bite and wait for its prey to bleed to death it would do something much more…torturous, it would use its gigantic jaws rip out a 550 lb. chunk of flesh with a single bite. It would use this method to actually eat its enormous prey (Argentinosaurus) alive! If it gets bitten enough it would soon die from infection and blood-loss.

So my final measurements (maximum) are:

Length: 13.7 m (45 ft)

Weight: 8.7 tons

Hip Height: 4.4 m (14 ft)

Spinosaurus aegypticus:

Spinosaurus was made famous thanks to the film Jurassic park III, But ever since its discovery paleontologists knew they had their hands on something special. By 1988 it was listed as the longest Theropod dinosaur at 15 m (50 ft) and 4 tons, but what scientists didn’t know was that the specimen they had was actually a Sub-adult (IPHG 1912). When they discovered the fragmentary snout of a full blown adult (MSNM V4047) in 2005 scientists were baffled at what they had uncovered, the giant creature could have measured up to 18 m (60 ft) and weigh over 23 tons, word was quick to get out to the public. But ever since the estimates have been found to have been exaggerated, The measurements of the new specimen is in a solid range of 16-17 m (53-56 ft) but then we get into the weight debate I know a lot of people here put Spinosaurus at a solid 7-8 tons but new discoveries (such as the new species Oxalaia) have shown that Spinosaurus was a little heavier than his kin, most scientists now put its at 8-10 tons and so do I.

 Most people think that Spinosaurus had a very weak bite, a few weeks ago before I did my research I would’ve agreed but now… it’s a little different. Most of you would argue that it only ate fish and didn’t need a strong bite, and its diet was mostly fish but new discoveries show that those fish were monsters like the alligator gar (which had a hide so thick you can’t even break it open with a hammer) and giant sawfish that can decapitate at will, so it wasn’t the hardest biter but it bit…hard

My final Measurements (maximum) are:

Length: 17.2 m (57 ft)

Weight: 10 tons

Sail Height: 6.7 m (22.8 ft)

Tyrannosaurus rex:

The infamous Tyrannosaurus rex has had a lot of controversy surrounding it right now a lot of people argue that it was nothing but a lazy giant scavenger that stole food from other predators and that it also was a mere 12.3 m long and 7 tons while others argue that it was a smart and calculating pack hunter that weighed 13 tons and looked good doing it. So I had to choose which side I was on, I found out…I was on neither. Being the species with the most specimens in this list, we know a lot better about it than the other 3. The largest complete specimen is the infamous “Sue” at 12.3 m and 9 tons she was big but not as large as the others on this list, so I did a little more research that brought up my old weapons… MOR 1126 (C. rex) and MOR 1152 (F. rex). Most people argue that they are “too fragmentary” to be measured or estimated upon, I was one of those people…until I took a look at the bigger picture. Most specimens on this list are very fragmentary, one might argue that we have 32 specimens of Tyrannosaurus and only a few of the others, but if you think about there are only 4 T. rex Specimens more than 50% Complete, all the others are fragmentary! So taking into account that C. rex and F. rex are almost 7-15% complete they are good to be measured at 13.57-13.8 m (44-45.6 ft) and 8.7-11.05 tons.

Even though they lived in packs most of the time Tyrannosaurus had a bite none can match, with blade -like incisors on the front of its snout and bone Crushing on the sides and in the back, it had the deadliest set of teeth and the strongest bite force of any terrestrial animal at 18000 psi a Tyrannosaurus would take a bite and flex its jaw muscles, crushing any bone and ripping any flesh that comes in the way killing any animal instantly.

My final measurements (maximum) are:

Length: 13.8 m (45.6 ft)

Weight: 11.05 tons

Hip Height: 5.7 m (18.8 ft)

My final Comparison is:

Largest Theropod: Tyrannosaurus – Carcharodontosaurus

Longest Theropod: Spinosaurus - Carcharodontosaurus

Longest Theropod Skull: Giganotosaurus - Carcharodontosaurus

Highest Theropod: Spinosaurus – Tyrannosaurus

I hope you enjoyed and please note that all of this is based on research, mine and others.
