Mr Curry Roger Essay

Dr. Curry-Roger’s talk was very interesting and had many different points throughout. The first interesting point mentioned was that dinosaurs are birds. Dr. Curry-Roger explained that both birds and dinosaurs had a lot in common. She stated that birds have feathers that are complex, a fused clavicle, short bony tails, bones that are filled with air sacs, efficient breathing, and a fast growth rate. When comparing fossils to birds, they had many of the same features. Some dinosaurs had feathers, Dr. Curry Roger’s provided us with pictures of these feathers. Additionally, the bones of these fossils also showed evidence of air sacs and had reached sexual maturity quickly, showing that they too were fast growers. Additionally, new evidence shows that dinosaurs may have had collagen found on their claws. All of these combined coincidences make dinosaurs very similar to birds, and would explain the origin of birds.
The second interesting point Dr. Curry-Roger’s made was that there was plenty of science behind dinosaur reconstructions. The way scientists
There were many different theories that arose in regards to how dinosaurs became extinct. Some of the theories are floods, ice ages, poisoned food supply, etc. However, what most likely happened was a meteor crashing into the planet. The meteor caused an immediate impact on the life that it hit directly, causing them to vanish. The after effects were a drastic climate change and the fact that the meteor most likely caused a sonic boom that also ended the lives of many other animals. After the meteor hit, it probably caused volcanoes and made much of the land uninhabitable due to wild fires. Additionally, after this period of heat there was chance of a period of cold and dark. Together, this all combined was the reasoning behind why the dinosaurs, and most life went extinct, despite being in their prime and the most diverse they had ever
