It is rare to think that someone who don’t know about the dinosaur in his or her lifetime. But overall, you can find someone who already knows about the existence of dinosaur. From our non-sanguine conviction, we can expect that the dinosaur has extinct due to the outer space intervention. But in the reality, we not still know what is the real cause for the massive extinction from our planet. It is true that you will never come to the conclusion that this huge giant could not vanish immediately with an outer space influence. Practically, if you have an observant mind, then you will get that the mass extinction had occurred through a long period of thousand years.
It is the norm in the nature is that nature never destroy anything instantly in the massive scale. Rather, you will get the evidence about the extinction in a slow and steady pace. When you will get into the core of the dinosaur massive extinction, then you will observe that a lot of factors have been involved with its downfall. You can describe these elements as big size, irregular vegetation, outer space bombardment, gene mutation, inland deformation, irregular migration, irregular food habit, interbreed fighting, low reproduction and diverse metabolism. You will see that the query about dinosaur extinction will be in the right direction.
It is true that if your body size is big, then you will have to face a lot of trouble physically and mentally. Hence, your existence will be unstable. In the case of dinosaurs, the big size body gave them unique disadvantage over the other animals at that time. Therefore, the dinosaurs got the different kinds of physical and biological complication over the time. Practically they never cope with their mammoth size with the unstable natural environment as well. It is one of the reasons for the dinosaurs extinction on 65 millions of year ago from this planet.
At the end of the Cretaceous period, the irregular vegetation at a particular region where the most of the dinosaur was living faced a tremendous shortage of plant due to the abnormal behavior of the natural environment and also earth’s abrupt plate tectonics movement.
Outer Space Bombardment
During the period of dinosaur ruling, the outer space assault was a regular event. But the intensity of the bombardment was irregular and abrupt as well. Therefore, asteroid and meteorites hitting on the earth make the situations more troublesome for the dinosaurs also. Practically, the dinosaurs were very in trouble at that time when the continuous low-intensity bombardment of the asteroids and comets deformed the earth’s atmosphere and its vegetation as well.
Over the times at that time, the dinosaurs faced the gene mutation due to constant change of the environment and habitat surrounding. Also, you will observe that the at that time, the dinosaurs could not protect themselves from the gene mutation immediately. The changing gene made the situation for the dinosaur more critical in the sense of body immune system against outside attack like virus, bacteria or parasites also.
During the dinosaur’s living period, the constant land formations made them more vulnerable to land deformation effect. The reason is that continuous inclement atmosphere in the land architecture, the dinosaur get trapped in its course in such a way that they could not move from one place to any other place for their better adaptability. If you are more radical in your thinking, then you will see that land deformation brought an enormous impact in their lifestyle as well. Due to the land deformation, the dinosaurs could not regularly migrate at all. Even, you will observe that irregular migration gave themselves more vulnerable to the sudden reverse acclimatization. Therefore, it is one of the primes reasons for the dinosaurs extinction from this planet.
Irregular Food Habit
Due to the inadequate supply of food supply had compelled themselves to change their food habit over the times. It hampered their body immune system and constitution as well. Even, they could able to produce enough body nutrient according to their body need. So they immediately pushed forward towards their extinction also.
After all, you can say that the inter-breed intense fighting for food made them towards quick extinction. The reason is that when the food pyramid could not provide the equal food supply to all layers of the food chain of the dinosaurs, then immediate the food pyramid got collapsed and pushed the dinosaurs towards disappearance.
Low Reproduction Capability
One central point and essential element for the dinosaurs extinction is that they could not do sex properly due to their massive body structure. It is also true that the big stature dinosaurs were extinct very earlier than the short stature dinosaurs. Practically, big sized dinosaurs had a small reproductive rate than the short sized dinosaurs also.
After all, you will able to come into conclusion is that the dinosaurs never vanish from this planet with a single cause of out space disturbance. Rather, they became extinct due to a series of different criteria that are responsible for.
