4/23/20 Physical Geology Missing In Action Define the term: mass extinction. The extinction of many species within a relatively short period of geological time, thought to be due to factors such as a catastrophic global event or widespread environmental change that occurs too rapidly for most species to adapt Late Devonian extinction Indicate the time (in millions of years) when the extinction occurred. When did it approximately start and end? The late Devonian extinction took place about 375 million years ago What catastropic events do geologist suggest caused the mass extinction? Tropical groups climate change may have been involved, and there is proof of geological evidence for cooling of the global climate at the end-Frasnian event and near the end of the Devonian Period. Some scientists may also be certain of that there may have been so little oxygen near the seafloor that only bacteria could have survived List and name of one of the more notable\ well-known plant and one animal that went extinct. Odontopleurid trilobites and Dalmanitid trilobites Describe two interesting facts about the extinction event. The Devonian, part of the Paleozoic era, is otherwise known as the Age of Fishes the Taghanic Event, which formerly was used to draw the boundary between the Middle and Upper Devonian, was a marked period of extinction for goniatites, corals, and brachiopods; Triassic–Jurassic Extinction Indicate the time (in millions of years) when the extinction occurred. When did it approximately start and end? The Triassic period was said to started about 251 million years ago and ended about 199 million years ago. What catastrophic events do geologist suggest caused the mass extinction? Even though this topic is still controversial by some, many scientists believe that the mass extinction was caused by climate changes and rising sea levels due to excessive amounts of carbon dioxide List and name of one of the more notable\ well-known plant and one animal that went extinct. The brachiopods, which is an undersea plant, along with reptiles went extinct during this period Describe two interesting facts about the extinction event. One of the most interesting fact of this period for me was the evolution from reptiles to dinosaurs. I find it to be very fascinating, along with how climate change was such an impact on
the extinction. We are currently dealing with climate change again on Earth, which makes one wonder how long it will be until a new period begins and what will be in store for humans. Permian–Triassic extinction Indicate the time (in millions of years) when the extinction occurred. When did it approximately start and end? The extinction is said to occurred near the end of the Triassic Period, about 201 million years ago. What catastropic events do geologist suggest caused the mass extinction? The end of the Triassic, the supercontinent of Pangea began to break (rift) apart. This led to global warming and changes to the oceans List and name of one of the more notable\ well-known plant and one animal that went extinct. Brachiopods, shelled cephalopods and phytosaur Describe two interesting facts about the extinction event. Permian extinction was the worst extinction event in the planet's history it was likely to have wiped out more than 90 percent of all marine species and 70 percent of land animals. So catastrophic was the loss of biodiversity that earth took nearly 10 million years to recover from the loss.
