What else can I help you with?
The evidence that supports that in impact event caused the Triassic-Jurassic extinction is a layer of which is rare on Earth.?
The evidence supporting the impact event causing the Triassic-Jurassic extinction includes a layer of iridium-rich clay, which is rare on Earth and often associated with extraterrestrial impacts. This layer indicates a sudden and significant event that would have led to drastic environmental changes, contributing to the mass extinction. Additionally, the presence of shocked quartz and other impact-related materials further supports the hypothesis of an asteroid or comet impact during this period.
How do you know a mass extinction actually did occur?
No evidence of the extinct lifeforms appears in the stratigraphic record immediately following the extinction event.

What evidence suggests that we could be experiencing a sixth mass extinction?
Evidence suggesting we could be experiencing a sixth mass extinction includes the high rate of species extinction, the loss of biodiversity, and the significant impact of human activities such as habitat destruction, pollution, and climate change on ecosystems worldwide. Trends in population decline and habitat loss further support the hypothesis of a sixth mass extinction event.
What is a very sudden elimination of a species from a catastrophic event?

What are the extinction of animals in the very distant past?
There were five major extinction events in the past. They are called the Cretaceous-Tertiary (or K-T) extinction event, the late Devonian mass extinction, the Permian mass extinction, the Ordovician-Silurian mass extinction and the Triassic-Jurassic mass extinction event.
How do scientists know that KT extinction took place?
When we see that there are fossils found in a certain geological layer, which are evidence that a certain species existed at that time, and then in the next geological stratum we no longer find those fossils, and there is no evidence that the species which used to exist still exists, we infer that the species became extinct. If a whole lot of species become extinct at approximately the same time, we call that an extinction event, such as the KT extinction.
