Most likely, the end of the last ice age.
A sudden unexpected change in the environment is likely to trigger a response such as fleeing or seeking cover to protect oneself from potential danger.
Icthyosaurus died out around 93 million years ago. The cause of their extinction is unknown, but could have been climate change or, less likely, competition from plesiosaurs and mosasaurs.
most probably change in the climatic condition was the main reason for their extinction!!
Mammoths likely did not run out of food as a singular cause for their extinction. The extinction of mammoths is believed to have been caused by a combination of factors, including climate change, human hunting, and possibly disease. Changes in vegetation due to climate change may have affected the availability of food sources for mammoths, but it was not the sole reason for their extinction.
Most likely, the end of the last ice age.

A species that is genetically diverse is more likely to survive in the event of a major change in it's environment, because of chance. A large swing in climate for instance, could entirely wipe out a species that was solely suited to a specific climate. However, if a portion of the species is more adaptable to a colder climate, and a portion is more adaptable to a warmer climate, even though a climate change would mean death for a large portion, a portion would be more likely to survive.
The Phacops rana, a species of trilobite, became extinct during the end-Devonian mass extinction, which was likely caused by a combination of climate change, volcanic activity, and a drop in sea levels. These environmental changes likely disrupted the trilobite's habitats and food sources, leading to their extinction.
