Dinosaur Extinction Theories

Dinosaur Extinction

Asteroid

~ Big Big Space Rock

~ Instantaneously destroyed everything

~ Punched the World's Reset Button

Volcanic Eruptions

~ Tectonic Plates Shifted

~Lava From Several Volcanoes Burned Everything

Some scientists believe that certain aspects ended dinosuar life all together. On the other hand, other scinetists have come to the verdict that a combination of events caused the extinction of dinosaurs. What if it was a multitude of events linked together that in all concluded the life of dinosuars?

Transition

Asteroid

When an asteroid punches Earth's surface, it fractures the crust and the other layers off the Earth. Following that, molten lava seeps throught the creaves of the Earth and speeds up the process of volcanic eruptions.

Food Chain

Volcanic Eruptions

Herbivores rely on plants for food and without the natural supply of plants, herbivores would die out slowly. Consequently, the omnivores and the carnivores would also die from starvation because they depend on herbivores to eat.

With all of the volcanos erupting, lava, sulfur, and volcanic material were being emited into the atmosphere. All of the ash and volcanic material coming from the eruptions caused the skies to darken and the sun to be concealed.

Photosynthesis

Lack of Vitamin D and Rickets

Lack of Vitamin D

Also, the lack of sunlight upset the course of photosynthesis. Without photosynthesis, plants could not use the energy from the light to produce oxygen into the air. In addition, without sunlight it would minimize the plant growth all togehter.

Since sunlight was scarce, dinosaurs could not recieve the substantional amount of vitamin D. Vitamin D is used to maintain strong bones and without it, the disease Rickets came about. Rickets is the weakening of the bones.

~Important vitamin needed for the body's bone strength.

~Vitamin D is provided by the sun.

~The ash and debris from the volcanic explosions were clouding the sky and the sun rays vanished.

~ Tectonic Plate Movement Caused Ecosystems to Fall Below Sea Level (marine regression)

~ Resources Became Limited Causing Food Chains To Become Unbalanced

Extinction Cycle

~Caused by lack of vitamin D

~Disease that deformes bones and turns them floppy and breakable.

Rickets

Food Chain

What if every theory was correct? Is it possible that they all could have taken place?

~The plants could not absorb light energy to create food for other organisms or in fact, maintain life itself.

~Herbavores were scavaging for food because they depended on plants to sustain their life.

~ Anoxia is when not enough oxygen is in the air.

~Some scientists believe that plants could not produce oxygen because of the weather conditions so there was a lack of oxygen causing the dinosaurs to die by carbon monoxide.
