How about this. Maybe that was a shoreline at one time and that’s where the whales beached themselves. It’s not like it never happened before.
So, if the Earth had a fever (algore) and the sea levels rose, this might have been under water?
Algore was right all along...except the “man made global warming” part. What a bunch of maroons!
What has never happened before is sea creatures beaching themselves and dying without getting chewed to bits and scattered.
And it never will happen - life is hungry.
