Modern elephants weigh about 5 tons and produce about 20lbs of dung per defecation
Argentinosaurus huinculensis, the biggest land animal ever, weighed about 100 tons on the high end. As herbivores, their feces were probably the same consistency as elephants. Therefore we can assume almost the same mass, so a 100 ton Argentinosaurus could produce roughly 400lbs/181kg of feces in one defecation. Let’s say the average saruopod’s anus is about 4m off the ground (comparing with this 2m/6ft human)
Ignoring air resistance and any pushing by the animal, it would take the poop about a second to hit the ground and it would hit the ground at 8.85 m/s or 31.88 km/h. This is about 1601.85N of force. It takes about 3000N to break a human neck. So even if you were to lay flat on the ground, the crushing force of the falling dino-rhea wouldn’t be enough to kill you, but it would be quite painful. However, you’re now covered in a 400lbs pile of shit and you will probably suffocate and die. Thanks for coming to my TED talk
The fact that the Midwest just got cold enough to kill you in minutes of being outside because of an unprecedented polar vortex means that our planet is now starting to become uninhabitable due to climate change. We’re going to look back on this moment for a long time to come.
