Perucetus colossus, or "the colossal whale from Peru,"
600 feet or 182.9 meters
the one that killed the dinosaurs was estimated to be more than 10 Km or 6 miles wide
The blue whale may no longer be the largest animal ever

Thanks Tahanson

While we see war in the world today, humans are also going to face events from nature, a large Volcano or a 'Space-Rock' Tunguska likely measured between 328 and 656 feet (100 and 200 m)
The Tunguska and Chelyabinsk meteoroids to the have been compared to the size of the Eiffel Tower and Empire State Building, one large enough to be compared to the base of the buildings and another small enough to be compared to the top sections of these buildings

Interesting close call with Asteroid ZTm0038...
Think you have them all mapped... and then a 400m wide one reminds you that "space doesn't do statistical analysis"

But, as said for many years... the bigger threat are comets... billions of em in the Oort cloud..

The Largest Impact Crater on Earth, 520 km Across, Might Be Hiding Under Australia
https://www.universetoday.com/162833/th … australia/
Asteroid impacts have arguably killed off more species than almost any other type of disaster since life began on Earth. The most famous of these, the Chicxulub impactor, killed the dinosaurs about 65 million years ago, along with 76% of all species on the planet at the time. But that was by no means the worst disaster; as far as we can tell, it wasn’t even the biggest asteroid. That title currently goes to the Vredefort crater in South Africa. Coming in at over 300 kilometers wide, it was the largest asteroid crater so far found, at least when it was formed about 2 billion years ago. But that might be about to change if a theory from Andrew Glikson and Tony Yeates of New South Wales is correct. They have found what they believe to be the biggest impact crater on Earth since the Late Heavy Bombardment in their own Australian province of New South Wales, and they think it might have caused one of the other five mass extinction events.

The latest issue of Analog contains a fact article about the precise timing of the arrival of the asteroid that killed the asteroids 65 million years ago .... The discovery allows scientists to specify with accuracy that the event occurred in Sping in the Northern hemisphere. A huge fish kill was discovered, and the fish were so well preserved that the presence of glass spheres was found in their gills but not in their digestive tract, indicating that the flood that sloshed all the fish out of their river occurred after the spheres of glass had fallen out of the sky, but before the fish had time to eat anything.

Devastating Clouds of Dust Helped End the Reign of the Dinosaurs
https://www.universetoday.com/164024/de … dinosaurs/
When a giant meteor crashed into Earth 66 million years ago, the impact pulverized cubic kilometers of rock and blasted the dust and debris into the Earth’s atmosphere. It was previously believed that sulfur from the impact and soot from the global fires that followed drove a global “impact winter” that killed off 75% of species on Earth, including the dinosaurs.
A new geology paper says that the die-off was additionally fueled by ultrafine dust created by the impact which filled the atmosphere and blocked sunlight for as long as 15 years. Plants were unable to photosynthesize and global temperatures were lowered by 15 degrees C (59 F).
