Dearest Dinosaurologists and the spirit of  Dicky  (quick kwiz, whom am I referring to ?,,,,easy peasy lemon squeezy)




Dinosaurs are my all time favourite animal that lived millions and millions*of years ago !  Out of all the Triassic reptilian animals that existed millions of years ago, Dinosaurs are my No 1 fave.


(* For all the creationists, that's a bigger number than 6000. I know it's difficult because it;s a big number but.....try !!)




Look here's a happy bunch having their day ruined by a cataclysmic event.



A happy bunch of Dinos about to have their day ruined millions of years ago just now. Bona-fide real photo from the time.






So, as a consequence of the extinction event do ewe think it's probable that bits of dinosaurs are floating around us in orbit ?

I’m referring to the impact blast ejecting Dino space bound.



I propose we send some paleontologists up there with a net




whajafink ?




Hugs and shmishes

Oh Dino, Oh Dino
I hear ewe went to war
With a massive rock from outer space
And now you're dino-SORE !!!  lol

The Chicxulub impact was absolutely enormous: in the range of 100 million to 1 billion megatons. That sounds like it would easily send pieces of rock into orbit. If there were dinosaurs already fossilized near the site, I'd expect small chunks of fossilized bones could possibly be thrown out of the atmosphere. As for dinosaurs that were still alive at the time, they'd probably be vaporized by the blast.

The amount of energy required to launch a piece of rock into orbit is enough to melt rock.
That same amount of energy would destroy flesh and bone.

Yea, OK, we all acknowledge that it wouldn't much resemble the original critter (nicely cooked if it was still alive) and it would just be tiny bits.  No intact cells for instance.

It's really hard to ballistically put anything into orbit from Earth.  Anything that goes up is either above escape velocity or on a trajectory that will bring it right back in one swing. Only the stuff that is subsequently re-deflected into an orbital path has a chance of staying in orbit.

Of course the entire mass of the moon pretty much qualifies as material ballistically ejected, so it very much does happen.

I think if a really big dinosaur like a brachiosaurus was in the right location part of could well reach an earth synchronous orbit, before it disintegrated. I would think that any ejection though will have been recouped by the earth over time. The actual impact site though tends to compress and any surrounding area are pushed sideways rather than up as in an explosive blast wave, the main upwards ejection seems to be from the crater. The KT impact struck in a shallow sea, I suppose it is more likely to find marine beasties than a t Rex.

Hi.

do ewe think it's probable that bits of dinosaurs are floating around us in orbit ?

    It's possible - but really little tiny bits of dinosaur.   Rather than just being in orbit, it's possible that bits of rock containing some proteins and possibly bits of nucleic acids like RNA or DNA had enough velocity to escape earth and drift off somewhere else.
   There are theories that suggest Earth might have had a boost to the development of life from meteorites that fell to earth containing useable nucleic acids and proteins.  In its biggest or most extreme form that might have included intact and viable micro-organisms but a weaker form of this is just that some useable proteins and nucleic acids may have become incorporated into a lipid bound vesicle of water (a primitive cell).
    So it's quite possible that earth could do the same and provide some material to some other planet.
