As we know, the Jurassic period was ruled by the dinosaurs. If I tell you there was almost 10 million years dark age for the dinosaurs. That is the Early Jurassic Extinction. We supply all kinds of animatronic dinosaurs, Whatever the Triassic, Jurassic and Cretaceous. Make the dinosaurs vivid: Roar, eye blink, arm shake, neck shake and tail shake. We also can supply the animals and insects. Please visit us at: www.justdinosaur.com. Hope you may like it.

The Triassic - Jurassic Extinction, although it called the 5 biggest extinctions in history, but not extinct dinosaurs that much. Even it brought the dinosaur to be the ruler of this period. It lasted about 17 million years. Then the Early Jurassic Extinction came.

The early Jurassic extinction event, also known as the Toarcian extinction event, occurred at the turn of the Pliensbachian-Toarcian period about 183 million years ago, due to the global greenhouse effect caused by the Karu-Ferrar large igneous province located in South Africa and Antarctica. During this extinction, the oceans were severely damaged and land life was also badly hit, with the Number of dinosaurs in the Toarcian period significantly lower than in other parts of the Early Jurassic.

As for the detailed causes, the first and most obvious is that massive emissions of carbon dioxide into the atmosphere are causing global warming and acidifying the oceans.

As carbon dioxide levels increase, oxygen levels decrease, leading to a lack of oxygen in the oceans. Global warming releases gas hydrates from shallow waters into the atmosphere, creating a vicious cycle that worsens global warming.

In general, what happened on earth during a Toarcian extinction event was a huge chain reaction. And the Karoo-Ferrar igneous province is estimated to have erupted for nearly 10 million years, which means that during those 10 million years, earth could have been no different from the hell.
