A new analysis of the 18 species cutting strength of the meat -eating dinosaurs shows that when the tirenosus Rex Skull was improved to cut the skull, other large, hunterial dinosaurs, the two legs were walking on two legs – spinosurus and alovascular and alooschen.
I reported Existing organismsThese results show that the meat -eating dinosaur followed various evolutionary routes in terms of scalp design and feeding style.
“The meat -eating dinosaur has taken a lot of different routes, turning into giants in terms of feeding bio -mechanics and potential behaviors,” said Andrew Roy, UK’s Bristol University.
“Tyranosors developed the skulls for power and crushing cutting, while other tissues have a relatively weak but more special scalp, which also offered diversity of feeding strategies on large -scale size.
Roy has always been attracted by big meat -eating dinosaurs, and they look for the basic questions in biology. They consider them interesting articles. In this study, he and the co-author Emily Ray Field wanted to know how bipodallism or two feet walking-bipolar bio-mechanics and feeding techniques.
Earlier, it was known that despite reaching similar size, hunter dinosaurs were manufactured in many different parts of the world at different times and the shapes of the skull were very different.
Ray and Ray Field, these facts raised questions about whether their skull was practically the same under the surface or if there were significant differences in their predatory lifestyle. Since there is no large-scale, biopsy of meat eaters even today-even since the end of the closing cratesis, since the extinction of the massive-scale, the audience notes that the study of these animals offers interesting insights about a lifestyle that has disappeared since then.
To examine the relationship between physical size and bio -mechanics of the scalp, the authors have used the skull mechanics, analyzing the efficiency of feeding, and measuring cutting power in 18 species of the terrapedes, using CT scan and surface -larger scanned. Although they expected some differences between the species, they were surprised when their analysis showed a clear bio -mechanical deviation.
“Tyrunosorides like Tea Raxes were improved for high cutting forces at the price of skulls, Roy says.” “But in some other giants, such as giganotosis, we calculated tension patterns, which suggested relatively light cutting. It went home to see how evolution can produce numerous ‘solutions’ in life as a large, meat bipoop.”
The tension of the skull did not show the size of the size. Some small thyropes experienced more stress than some major species due to the increase in muscle volume and cutting powers.
These results suggest that being a hunter biprum was not always the equivalent of being a bone crushing giant. Unlike Tea -C -Rex, some dinosaurs, including Spinosor and Al -Lusor, became giants, while maintaining weak cutting and removing meat more suitable.
“I compare the ulcers to a modern kumodo dragon,” says Roy.
“Large tirenosor skulls were rather improved like modern crocodiles, which contained high cutting forces that crush the victim. This bio -mechanical diversity shows that the dinosaur ecosystem often assume we often assume with less competition and more expertise.
