Why did the Jurassic time period end?

The Jurassic time period ended approximately 145 million years ago, transitioning into the Cretaceous period. This transition was marked by significant geological and climatic changes, including shifts in sea levels and the breakup of the supercontinent Pangaea. While the exact causes of the end of the Jurassic are not fully understood, it is believed that these environmental changes, along with volcanic activity and possibly asteroid impacts, contributed to the extinction of various species and the evolution of new ones.
