Why are ammonite extinct?

The ammonites went extinct during the Cretaceous-Paleogene extinction event that killed off the dinosaurs around 66 million years ago. The asteroid that impacted Earth (at what is now the Chicxulub crater) caused extreme climate change and widespread fires. The impact would have had a devastating impact on the ammonites:

- Extinction via climate change: The impact would have caused a sudden and dramatic change in the climate. Ammonites were not able to adapt to these changes quickly enough and died off.

- Extinction via loss of habitat: The impact would have caused widespread devastation, including the destruction of ammonites' habitats. Many ammonites lived in shallow waters, which were particularly affected by the impact.

- Extinction via food chain disruption: The impact would have also had a ripple effect on the food chain, with many of ammonites' prey species being killed off.
