@GuateGojira :
About #960: you wrote : About the Spinosaurus, I did not knew about that new study, thank you for sharing it! I was reading the conclusions but I am agree with Dr Ibrahim, the study is far from conclusive as this is just a simulation, also I am happy that new fossils will arrive and will provide more information, which is excelent. Other thing, I think, and many other too, that Spinosaurus was not like an Alligator in the water, but more like a Bear. This is nothing new, but it seems that is the contradiction in the Dr Henderson study. In fact, Henderson accept that in the interview! The final answer came from Dr David Hone: "swimming is by no means the litmus test for a life aquatic". Probably Spinosaurus had good swiming capabilities but that doesn't mean that they spend they entire life in the water. The articel says: “Herons aren't very good at swimming, but they spend most of their time knee-deep in water, wading around the edge of rivers,” he says. “ 'Semiaquatic' might be a push, but you're definitely talking about an animal whose ecology is fundamentally linked to water.” Spinosaurus was especifically linked to water, so it will be absurd that it will not have some "aquatic" habilities. Like I said, it was like a bear. Bears are not designed to dive, but they can do it for short times. So, that is the answer. Now, about Spinosaurus vs T.rex, no land predator, present or extinct, will be a rival for the Tyrannosaurus rex, on land at least. In the words of Dr Henry Orborn: "Tyrannosaurus is the most superb carnivorous mechanism among the terrestrial Vertebrata, in which raptorial destructive power and speed are combined". Very happy to read such conclusions like these ones about the T.rex ! After having read the Jack Horner's book "The complete T.rex" I remember to have been in total disagreement with his theory i.e. the T. rex was a total scavenger. I prefered the Robert T. Bakker's depictions which were revolutionary. As for the spinosaurus, no one crocodile brought a sail-like dorsal as spinosaurus did. To imagine it swimming and diving in depth like a croc ? Very, very difficult ! |
