TIL one of the moon rocks brought back to Earth from the Apollo 14 mission, was actually a rock formed on Earth 4 billion years ago, making it Earth's oldest rock.

Yes, I wish I could remember the exact book I read with the most detailed calculations... it was a short but fascinating self published book on amazon, by a scientist about 3 to 5 years ago.

He really focused on the "ejection of entire animals into space" theory, and did the calculations, wanting to know if entire dinosaurs were ejected into space, intact!

And according to him, they were, likely by the tens of thousands...

So if anyone knows the name of that book, let me know!

HOWEVER... fear not!

Because while I may have forgotten the name of that book, I can still recommend you to at least 1 DETAILED scientific and fascinating to read book on this topic, that comes to the same conclusion!

Essentially, the second-book is called:

"Chicxulub: the Impact and Tsunami"

It describes a lot of the same impact forces, angles, and ejection of matter/animals/trees into outer space!

But more than focusing on ejection of matter into space, it focuses a lot more instead on the other interesting (and horrifying!) effects that impact had on the entire planet and land animals.

Let's just say this is the BEST BOOK I've encountered that vividly describes what that one fateful day would have been like if you were standing/living on Earth's surface.

As well: that second book book also describes how pretty much ALL of the Earth's surviving land animals would have lost their hearing due to the sound of the shock waves of that impact event (if I remember correctly and am not confusing the 2 books).

I mean imagine that:

ALL creatures on Earth simultaneously go deaf!

It's a big miracle anything survived after that day.

So ya, that second book, "Chicxulub: the Impact and Tsunami", was written by David Shonting (an Oceanographer Scientist) and Dr. Cathy Ezrailson, who seems to have multiple degrees in science and education.

All in all, I think it's an amazing read, and I'm surprised it didn't gain bigger attraction.

In the end, if you want to know what it would be like to travel back in time, 65 million years ago...

Then just read that book!
