"I guess it washed up on the waves."
I have to question how that is not religion.
I have to question how your babblings are not in CN, or being pored over by a mental health professional, but that’s life.
Dead whales are washed up all over the place, the rotting process fills (for a while) the interior of carcasses with gasses that increase buoyancy, high tides and rough seas would do the rest.
The fact that it is in a Mangrove swamp puts it in a brackish (semi saline therefore coastal) environment, so although “whale found in the Amazon forest” is true, it’s not quite the fortean event the headline suggests. The layer of dried plant matter beneath the corpse in the picture is also suggestive that was the high point of some wave event, a low pressure system where there is literally less air above an area can cause storm surges by sucking up the ocean (Katrina caused an 8 metre rise to inundate New Orleans), add this to natural high tides, subsea topography and there is no miracle at all, this is well documented and predictable stuff, so your incredulity is forced and purposeful, as is this whole troll thing about dinosaur existence.
But hey, it gives us something to do.
Kind Regards, Jura.
