The Role of Fungus in the Extinction of Dinosaurs


The debate over what ultimately killed off the dinosaurs is an area of great interest to not only scientists, but everyone. The dominant thought seems to be that an asteroid struck the earth at the end of the Cretaceous period and killed off much of the fauna and flora inhabiting the earth. However, the sequence of events following that mass extinction has been fairly blurry until a recent discovery, published in a recent issue of Science, by paleontologists Vivi Vajda and Stephen McLoughlin. These discoveries have revealed that during a period from anywhere between a few months and a couple of years after the asteroid stuck earth, fungus served as the dominant flora across the globe (Vajda). This point is reiterated in a news report published by the Swedish Research Council (SRC) soon after. In this essay, I will analyze the credibility of the research performed by the two paleontologists, the accuracy of the media article in conveying the Journal’s message, and I will provide some of my own thoughts as to how believable I interpret this account of what actually happened to the dinosaurs and floral life after the impact to be.

Paleontologists Vivi Vajda, from Lund University, Sweden and Stephen McLoughlin, from Queensland University of Technology, Australia, recently finished research in New Zealand regarding the significant rapid decrease in the diversity of plant species during the brief period following the asteroid’s collision with earth. In their research, Vajda and McLoughlin examined a 10 cm thick layer of coal, known as the K-T Boundary, which represents the time period when the Cretaceous era ended and the Tertiary began. In this thick coal layer of earth,...

...actly when the impact of the asteroid occurred, how much damage it truly did, and how long the period of atmospheric darkness lasted, I believe that there is enough positive data to persuade even the most skeptical audience. This recent discovery of the flourishing fungi during a period when larger plants died is just another stepping stone in solving the mystery of what truly happened to the dinosaurs for good. I believe this research is, overall, very credible and establishes a reliable theory of what exactly happened to the dinosaurs and what life was like during the period following their demise.

The Extinction of The Dinosaurs Essay

- 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....   [tags: asteroid, climate change, food]

Essay on The Cretaceous Extinction Event

- Cretaceous Extinction Event Causes, Evidence, and Effects on Biodiversity The most significant event of the Cretaceous era came at its end. Nearly 65 million years ago, the second most severe mass extinction in earth’s history occurred. This resulted in the loss of around 80% of species living at the time. Though nowhere near as severe as the end-Permian mass extinction, the end-Cretaceous extinction is the most well known mass extinction event. This is due to the violent event that caused it the extinction, as well as the chapter of earth’s history that it closed: the Dinosaurs....   [tags: mass extinction, dinosaur, asteriord]

What Really Happened to the Dinosaurs? Essay examples

- During the course of history, two theories have evolved that explain what happened to the dinosaurs.  These two theories have been debated back and forth between evolutionists and religious followers.  Evolutionists believe that dinosaurs became the most powerful beings on Earth around 235 million years ago.  They believe that no humans existed at the time.  Evolutionist views also say that all the dinosaurs were killed by a cataclysmic event.  On the other hand, the Bible says that God created the dinosaurs on the same day that he created Adam and Eve (Ham, 2007)....   [tags: Evolutionists, Biblical Views, Dinosaurs]

Theories of the Extinction of the Dinosaurs Essay

- Theories of the Extinction of the Dinosaurs Controversy surrounds the extinction of the dinosaurs. According to one theory, dinosaurs were slowly driven to extinction by environmental changes linked to the creeping withdrawal of shallow seas from the continents at the end of the dinosaur era. Proponents of this theory propose that dinosaurs dwindled in number and variety over several million years. An opposing theory proposes that the impact of asteroid or comet caused catastrophic destruction of the environment, leading to the extinction of the dinosaurs....   [tags: Papers]

Hypotheses on the Extinction of Dinosaurs Essays

Greedy scientists and civilians, searching for their own prize skeleton, rushed to rip bones out of the ground, destroying the fossils as they went. It was not until later in the century that scientists and paleontologists began pondering how such widespread creatures disappeared. Currently, paleontologists debate the two main hypotheses of how the classic dinosaurs died: from volcanic activity or an asteroid impact....   [tags: Exploratory Essays Research Papers]

Extinction Of Dinosaurs Essay

- Could an exploding star have been responsible for the death of the dinosaurs. This idea has become popular again as an explanation for the disappearance of the dinosaurs. An exploding star can blast material enormous distances into space. If this material reached Earth’s atmosphere, changes may have occurred that were harmful to life. We call an exploding star a supernova. Nova is the Latin word for new, and in ancient times, when an exploding star was observed, people often thought a new star was being born....   [tags: essays research papers]

Mass Extinction Essay

- ABSTRACT Several mass extinctions have occurred during the Earth’s history. The Cretaceous – Tertiary Boundary (K-T) Extinction caused the loss of at least three-quarters of all species known at that time including the dinosaurs. The cause of this mass extinction is a controversial subject among scientists but the fossil evidence of it’s occurrence is abundant. INTRODUCTION The K-T Extinction occurred 65 million years ago. Many species perished in that extinction. Today evidence for this extinction can be seen in the fossil record....   [tags: K-T Extinction]
