The Animals became too large in size is one hypothesis behind its demise

It is a fact that whatever killed the dinosaurs did not kill Ichthyosaurs because their fossil records indicate they went through a mass extinction before the dinosaurs. However similar conditions could have led to their demise. One theory is that waters which the Ichthyosaur's inhabited cooled for unknown reasons and their food supply started to dwindle. Because their massive bodies required massive consumption the decrease of food sources made the animals prone to starvation. evidence of this is shown in the fossil record as well

There are many theories answering how dinosaurs became extinct A common one is that Earth was hit by an asteroid, but there are many more. But these are all just theories. No one knows for sure how they became extinct.
