What organisms were lost during the Triassic-Jurassic event?
The Triassic-Jurassic EXTICTION event took place 199.6 million years ago, shortly after the beginning of the age of dinosaurs. It is one of the five largest bulk demise in history, similar to the size of K-T extinction that would exterminate dinosaurs 135 million years later. This mass extinction would prepare a way for dinosaurs to become dominant than that before. Triassic-Jurassic Extinction is an event that separates the triassical and Jurassic periods, both parts of a longer mesozoic era. The extinction of the Triassic-Jurassic is one of the least studied mass extinction because it lacks the size of the Permian-Triassic (erased by 99.7% of all types) or the proximity of the frequency and all the current and all current and all current and all current and all current and all current and all current and all current Morning-not and all current and most current and all current. Change, impact of asteroids and eSuperchanno's Rupce (usual suspects) - have a lack of evidence. For the climate insulation, it seems unlikely due to the sudden extinction of marine life, while the idea of the impact of the asteroid is at best speculative because no known large craters date around 199.6 million years. The central Atlantic magmatic province has exploded this time, but Palynological studies suggest that mass extinction occurred before the earliest volcanic eruptions.
The vertebrate casualties of the triassic-jurassic Were All the giant Amphibians (only the gondwanan-Antarctic, South American, and Australian-Taxons, Brachyopidae and Chigutisauridae) with the dinosaurs (Thecodonts and Crurotarsans), and Many Large Families of Therapsids (The descendants of mammals, formerly known as "mammals similar to reptiles", although not reptiles). These holes left nichesPoorly defended and mature for taking dinosaur. This dinosaurs dreamed to consolidate its position as a leading taxa (superorder) of earthly animals, which the government would continue for more than one hundred million years.
It is assumed that the Triassic-Jurassic EXTINCTION event has been exterminated by 50% of all living species, including 20% of seafood and 30% of the sea families, including many ammonite families. Many simple invertebrates died and also several more complex, including most of the nautiloid cefalopods.
