Pfhorrest : Your explanation and illustration of carbon-14 decay is misleading. It's not like one of its electrons spontaneously combusts and becomes an electron and an electron antineutrino. One of its *neutrons* "spontaneously combusts" (because of rare interactions between its constituent quarks and ambient W bosons, which flip an up quark to a down quark [edit: reverse that]) and emits the electron and electron antineutrino. The emission of the negatively charged electron turns the neutral neutron into a positively charged proton, and the mess that becomes of the particles' quantum numbers when that happens generates the electron antineutrino to balance it all out. It's the change of the neutron to proton that makes it into a different element (carbon to nitrogen), and none of the already-orbiting electrons have to be lost in this process; actually, the nitrogen-14 will want to grab another electron from the environment (like the one it just emitted) for its electron shells, now that it has one more positive charge in its nucleus than it did before.

Steve Vicari : Here I go again... Requesting the same this as last week, and the week before... And the week before... Can we please see a episode about Pleistocene Australian megafauna? Please?

Denver Fowler : Thank you for the interest in our research. It is worth noting that a later study by fish expert Mike Newbrey et al. (in 2013; I am one of the coauthors) showed that the fish vertebra is identical to those found in the 70 million year old Nemegt Formation of Mongolia, and that this specific type of fish vertebra has not been found anywhere else. Thus, there is little doubt that the "Raptorex" fossil is from the Nemegt Formation of Mongolia. The wikipedia article on "Raptorex" is quite detailed and covers these and more pieces of evidence. Denver Fowler.

Jose C. : A video about the evolution of spiders please.

hellboy2097 : In conclusion, profit hunters harm science. Sure they found a cool dino but because it was not recorded properly they screwed the science up.

The incarnation of boredom : "Did raptorex really exist?" My first thought: what the hell is raptorex?

Jawbreaker The Hyaenodon : Raptorrex:I’m the most controversial tyrannosaur ever Nanotyrannus:Hold my beer Raptorrex:But beer hasn’t been invented yet Nanotyrannus:This is a Youtube comment,it doesn’t have to make sense Raptorrex:YouTube hasn’t been invented either Nanotyrannus:... *Flips table and leaves* Raptorrex:Tables haven’t been invented yet either Nanotyrannus:SHUT UP!

Deadpool3E : There should be a Maury-type meme for this. "When it comes to the ontogenic results for Raptorex, Tarbosaurus bataar, you ARE the father!"

Tim parsons : Can you do a video of mammal-like reptiles please?

Bryce Mckenzie : Raptorex and Tarbosaurus are two of my favorite Dinosaurs. They're amazing!

Thomas Richter : none of that happen, all the evidence were planted there by the Flying Spaghetti Monster

Hafiz Aji Aziz : The decay process animation is wrong. Its supposed to be neutron that decayed, not electron

troytjuh : I would like to see a video about the evolution of kangaroos! :)

huahualipo : This is why we don't want for profit fossil hunters to do the digging because this sort of thing happens way to often when they do it. Sadly it's happening all over China right now (sigh

Servals : Looks like a juvenile Tarbosaurus to me, but I'm no paleontologist. I just think people are over eager to find and name "new" species, and that contributes to bias. It wouldn't be the first time someone made a juvenile into a new species.

DJ Crumrine : I like how this video also starts to discuss controversy. We think of science as something cold and rigid, but it’s a field full of passionate people just like any other career. I think a video on the history of how glamorized, shady and scandalous paleontology can get. Fossils are for everyone, not for private collections!

peppermintfoxy : Video ideas: Evolution of coelacanths/ other lobe finned fish Evolution of bioluminescence in deep sea creatures

Maximus Sparticus : This is just nanotyrannus all over again

L Guo : That moment when you realise the fossilized fish sitting on your desk are over 120 million years old.

Niklas Melton : Hey do you guys have any gear available? I really want to support the channel but I also kinda want a t-shirt...

SlamBoi : I love this channel! I love dinosaurs as well!

Daniel Staal : Honestly, I'm going with Occam's razor here: One explanation posits a new species, with features that are otherwise unknown at the time. The other says it's a known species, with features that were more common. Without good strong evidence otherwise, the explanation that doesn't bring *two* new facts to the field is most likely the correct one.

LEGOSAURUS : I love the skull pin :D

thes7274473 : Thanks a lot, amateur private fossil hunters…

rex_ noctis_ : Do a video about the evolution of cats ^^

tangmo mopet : What about Nanotyrannus?

sam rizzardi : Sounds like the name of a Gaulish assassin from the Asterix series

Mike Moore : It's a parrot. a beautiful Norwiegan blue I believe.

TheRoyalGallade [TRG] : ‘Can we not science our way out of this?!?’ Thats what i think every day.

Frank Kelley : What's up with monotremes?

Brian Johnson : How about a video on the evolution of Carnivorous plants?

Sheryl Hosler : That explanation of how radio-isotope dating works was really well-done!

Miroslav Georgiev : Isn't there also potassium dating?

Manuel Ucañán : is it the asian version of Nanotyrannus?

Nihar Gawand : A video about the evolution of Pinnipeds, please And awesome video as usual for someone who hasn't studied palaeontology but loves Prehistoric creature this channel is a bliss

Cities & Skyscrapers : I would like to see a video about elephant evolution.

H Ĕ Ł P ? : The evolution of seals please

King Nobody : the two-fingered hands and shape of the neck suggests to me that it is a tyrannosaurid and not a maniraptoriform. Of course, not having access to the fossils themselves means that my opinion is somewhat worthless as your graphic designers could make it look however they want...

Bo the Wolf : Do the evolution of wolves. Because wolves are cool, AROOOOOOOOOO

H K : I think it may be a juvenile, I mean if you think about it, a tyrannosaur-like dinosaur with two fingers seems a bit early for 130 million years ago There were small tyrannosaurs in the early cretaceous, but they didn't have two fingers

H Ĕ Ł P ? : You made me not fall asleep from having chemistry thrown at my face. *Congratulations*

BLT Player : The instance where science can't science.

Milky Wayan : been watching jurassic park videos for like two hours then this pops up in recommended and im like "i don't remember that hybrid"

Raisa Esmeral : I love these videos so much-!!!!! I watch these videos while am taking a break from my studies! Thanks PBS Eons!!!!!

【れい】Rotten Cabbage : Great video as always! Love all the EONS team and their hard work to share the science with the rest of the world. Just a little thing i need to say here: when i opened this video i expected it to be just another interesting video. Turns out it actually explains a lot about carbon-dating and other methods of determining the age of fossils. I'm a fan of that topic and i really liked your explanations (as well as the discussions happening in the comment section about the corrections), but it would be great if i could figure out what you were going to talk about before getting into it. maybe that's just me, but the title at a glance seems like a simple narration of a story that has little facts/ proper 'science'-y explanations in it. while i know for a fact that that isn't the case, but it would be great if you could express that through the title as well. Again, i have nothing but love and admiration for this channel and the team behind it!

pleb plee : Literally yelled yaas when I got the notification

Turbo Kong : I say this on pretty much every upload but DAMN do I love the eons channel. It fills my ancient life loving heart up with glee! Also nice pin, glad that you guys are involved with the comments and accepting (and encouraging) of corrections. Look forward to the next video!

Rohit Kossery : I love how much insight this episode provided on paleontology for those who have no background in the field. Could you guys please do an episode on marine reptiles from the mesozoic era?

Pass The Butter Robot : The fact that infants, juveniles & adults of the same animal species can often look very different must make life quite difficult for paleontologists. I imagine disagreements like this one must happen a lot.

Joaquin Elio : Thank you!!! We needed this. Background knowledge is important.
