The fall of Dinosaurs
It is hard to imagine that millions of years ago, the Earth was not dominated by humans, but by Dinosaurs. These great Beast’s, who were as big or bigger than cars, roamed the land. Some were giant killing machines, like the Tyrannosaurus Rex.Some are even alive today, while many people do not even notice. There have been countless theories as to how the dinosaurs became extinct.
The dinosaurs ruled the land for millions of years, and it seems impossible that such magnificent creatures could have been taken off the earth. Dinosaurs were very adaptable to their environment and traversed the entire earth. They were even found on lands like Antarctica, and many different oceanic islands like north Island, New Zealand, and a island called Spitsbergen.(Creation.com/Oard) There have even been Dinosaur fossils found in northern Alaska next to the arctic Ocean.(Oard) These questions have perplexed researchers, and it has made them wonder if dinosaurs were Endotherms, Ectotherms, or some combination in between.(Oard) An example of this is a comment from researcher Michael Benton,” Should we now imagine Dinosaurs as thermally insulated Warm-Blooded animals that ploughed through the snowdrifts and scraped brush the ice off the ground to find food?”.(Oard)
For the past several years, Different dinosaur tracks have been discovered at over 1,500 locations from around the world.(Oard) The number of tracks are in the
This researcher proposes that the dinosaurs did not die of heat, in fact she thinks the opposite, that they froze to death instead. Both articles have the same idea about a meteorite hitting the earth yet there is no concrete evidence as to what caused the meteorite to strike and what it did when it got here.
How did the dinosaurs really die? Located in the Bible have been verses that describe creatures that resemble what we might call dinosaurs. According to the Bible, dinosaurs were created by God, and existed over 6,000 years ago (Ham; Dinosaurs), and thanks to the evidence of the tissue found in the T-Rex bone (NBC News). This tissue couldn’t have lasted so long if it were any older. Many Evolutionists and Secularists state that the dinosaurs didn’t exist while the humans did, but state that they became extinct before the humans were even alive and say that they existed millions of years before humans (Ham; Dinosaurs). Dinosaurs couldn’t have died before the existence of humans because death was a result of Adam and Eve’s sin (Ham; Dinosaurs). All of the different species of the dinosaurs did broad Noah’s Ark, but those creatures that couldn’t board the cataclysmic event died and became the fossils that have been discovered by the many scientists of the world (Ham; Dinosaurs). After the Genesis Flood the earth was greatly changed because the sin of humans, death had entered the world. The teterous climate, lack of food, man’s sinful actions, and disease, were all results from the fall, and these results also became the results for the extinction of many creatures such as dinosaurs (Ham;
In conclusion, we rely on fossils and other scientific findings to help us understand how dinosaurs lived so long ago. The Jurassic Period was one of the more fascinating periods to learn about and one of the more interesting things that I’ve
Nobody knows for sure exactly how the dinosaurs became extinct. However scientists have speculated for decades about possible events that caused the dinosaurs to die out. Possibilities range from asteroids, to volcanoes, to climate changes. One of the more popular or well-known extinction theories involves the belief that an asteroid struck the Earth, causing devastating effects, and triggering mass extinctions around the end of the Cretaceous period.
Dinosaurs ruled the earth for over 65 million years and thankfully for the human race, they became extinct. Ultimately, only a major catastrophe could completely wipe out an entire species, let alone an entity of dinosaurs and the debacle on the causes of dinosaur extinction have flooded the minds of paleontologists for centuries. Geologist and zoologist Stephen Jay Gould published “Sex, Drugs, Disasters, and the Extinction of Dinosaurs,” to compare scientific and speculative causes of dinosaur decimation. Personally, I found this passage very informational and enjoyed reading it. Gould provides three theories that capture the reader’s curiosity, allowing room for pondering in one’s mind.
The main dinosaurs that died off were Sauropod dinosaurs, long necked, four legged dinosaurs, and stegosauridae, class holding Stegosaurus. Other species that died include ammonites, similar to the living animals called nautilus, many marine reptiles, and bivalves, relatable to modern mollusca. Not much is known about this extinction. It is mainly linked to climate change. So far, no connection to volcanic activity or an asteroid has been made. This extinction gave way to the Cretaceous Period.

One common theory many people have speculated about for years is whether or not dinosaurs were cold-blooded. After all, in the grand scheme of things, it made a lot of sense that they would be, seeing as such a successful, large, and diverse group of creatures seemed to have all of a sudden vanished in the blink of an eye, geologically speaking. Many, myself included, had come to believe that a giant asteroid had impacted the earth, kicking up debris into the atmosphere, blocked out the sun, and ultimately caused the extinction of the dinosaurs through negating their only source of heat. This theory made sense as they were regarded as “cold-blooded”
Because there were no known fossil non-avian dinosaur fossils in rocks younger than the K–T boundary, scientists have concluded that non-avian dinosaurs became extinct immediately before, or during the event. It is possible that small dinosaurs (other than birds) did survive, but they would have been deprived of food as both herbivorous dinosaurs would have found plant material scarce, and carnivores would have quickly found prey to be in short supply. Ectothermic (cold-blooded) crocodiles have very limited needs for food (they can survive several months without eating) while endothermic (warm-blooded) animals of similar size need much more food in order to sustain their faster metabolism. Therefore, under the circumstances of food chain disruption previously mentioned, non-avian dinosaurs died while some crocodiles survived. The survival of other endothermic animals, such as some birds and mammals, could be due, among other reasons, to their smaller needs for food, related to their small size at the extinction
The original discovery of the T-Rex was more than a century ago, but the unique creature has still managed to remain the main attraction in the dinosaur world. The reason stems from the creature’s mysterious
The age of the planet Earth is estimated to be about four point six billion years old. Life on Earth is estimated to have started one billion years later. Evolution has taken place since then. Evolving life from simple forms into more complex forms through the course of time. It all began with single celled organisms, prokaryotes. Later evolving in a period of two hundred million years, cyanobacteria began to produce photosynthesis. And life went on, evolving, adapting to its home. However through this course of time, mass extinctions have taken place on planet Earth. One of the most recent mass extinctions, has as a matter of fact left various amounts of evidence of the creatures which roamed the Earth at that time. Such magnificent creatures which varied from a very small size to giant sizes. Creatures which are now known to humanity as dinosaurs. The name of this extinction was the Cretaceous-Tertiary Mass Extinction. This extinction took place roughly sixty five million years ago. It has not been too long since this incident compared to the life span of the Earth. And yet it is still unclear how this extinction occurred. Paleontologists to this day, debate on how this extinction occurred. A major factor on what caused this extinction to occur was an impact of an asteroid. Another theory such as sea level regression is considered to be the blame for the extinction. Sea level regression is the drop of sea levels which aids to explain the marine mass extinction, however
People often wonder why a Tyrannosaurus Rex or a Centrosaurus is no longer roaming around the world today. They wonder about what happened to the dinosaurs, but they cannot be given a certain answer. That is because the disappearance of dinosaurs is an event in history that is still being debated today. There are different theories that try to explain the extinction, but the two theories that have been most accepted are the asteroid impact theory and the volcanism theory (Ducharme).
Plate tectonics did play a part in discovering what was the demise of the dinosaurs. Walter Alveras and his team were trying to discover why the Earth’s magnetic flip-flopped from south to north and they felt that the answers could be found in sedimentary rock samples. The sedimentary layer of rock was 65 million years old and formed a boundary between the Cretaceous and Tertiary periods, known as the “KT” boundary. This boundary was made of clay and it was a devoid of fossils.

Rapid climate change also ends up on the suspect list of possible dinosaur extinction events. During the latter part of the Cretaceous Period continents broke up causing volcanoes to erupt and fill the sky with gas and ash resulting in a drastic climate change (“Dinosaurs Climate Change and Biodiversity”). The shifting of continents changed the Earth’s landscape, altering weather patterns and overall climate (“Dinosaur Extinction Theories”). Also, over a long period of time, climate gradually changed. Ocean habits changed, temperatures grew much more extreme causing scorching summers and frigid winters (Norell, Dingus, and Gaffney). Radical temperature changes like these led to a green-house effect, making life for the dinosaurs a lot
