Yeah. Countless examples going both directions. I wouldn’t call crocodilians super adaptable, but they are so well tuned for their specific environs that they’ve been largely unchanged for 94 MILLION years.
I would argue that being warm blooded makes an animal more adaptable. Interestingly, it seems cold blooded reptiles evolved into warm blooded archosaurs which eventually led to cold blooded crocodilians. Tellingly, these active warm blooded ancestors are all extinct in favor of the passive, cold blooded, low adaptability ambush predator.
In the opposite direction, the adaptable rat has done much better than the countless specialized species that have disappeared since the industrial revolution and human explosion.
The thing about coastal areas is they’ll always be a part of Earth’s biosphere. Unlike plains or deserts or deciduous forests, which don’t have to exist, and can completely disappear, coastlines and estuaries can only move, never disappear.
A coastline absolutely can vanish(submerged) or be against geography, such as rocky cliffs, that is unsuitable. “Coastlines can’t stop existing, only move” is semantic nonesense.
EDIT: for ya downvoters, where’s the coastline on an island that vanishes due to rising sea levels? The Marshall Islands have a max elevation of ~7’ and are already having issues with rising sea levels. When the sea rises above them, where does their coastal ecosystem go?
