My Findings

I am back from Baltimore and here's a "report" on what I figured out about T-rex and Giganotosaurus. To measure the skeletons, I walked "heel-to-toe" alongside them(my feet are about 1 foot long). Because the skeletons were not exactly straight and my steps may have been slightly off, I decided to add or subtract 1 foot just to be safe. I also did this for the Tarbosaurus skeleton. Giganotosaurus- I counted about 40 ft for the total length. Because of the 1 foot addition or subtraction, this individual was about 39-41 ft long. Tarbosaurus- I counted about 31 ft for the total length. Because of the 1 foot addition or subtraction, this individual was between 30-32 ft long. Tyrannosaurus- I counted about 41 ft for the total length. Because of the 1 foot addition or subtraction, this individual was roughly 40-42 ft long. The Rex and Giga were very comparable in length. There was almost no difference. Both skeletons were adult animals. Because of the slightly small size of the Tarbo, I concluded that this individual was a sub-adult and would have been around 35 or 36 ft long had it lived. Based on the lengths and builds of the animals, this is what I came up with for weight. Giganotosaurus- 7-8 tons Tarbosaurus- 3-4 tons Tyrannosaurus- 7.5-8.5 tons The Rex skeleton was certainly more robust than the Giga one. I studied both individuals very carefully and there was no doubt about it. The Rex was heavier. This was a good situation as far as comparing the two goes. Both the Giga and Rex had similar lengths. The bones of the Rex were thicker and heavier than the Giga who seems to have had a slightly more slender build. The Giga had a skull that was slightly longer than the Rex's, but not as robust or heavy. In conclusion, while Giganotosaurus and Tyrannosaurus had comparable, if not equal lengths, Tyrannosaurus does seem to be the heavier of the two. In the "professional" world of paleontology, that means it was bigger. This is what I found out and concluded about Tyrannosaurus and Giganotosaurus. I am not favoring either dinosaur. Simply stating what I learned while visiting. Chapter 7 of The Fight To Survive will be up shortly ;)
