Try CuriosityStream today: http://curiositystream.com/eons Paleontologists have been studying and drawing totally different conclusions about the fossil LH PV18 for almost a decade. Is it just one of many specimens of a theropod called Tarbosaurus bataar or is it an entirely different theropod named Raptorex kriegsteini? In order to answer this question, you have to understand the many ways in which we can--and can’t--determine the age of a fossil. Thanks to Gregory S. Paul for allowing us to use his illustrations in this video.

Comments

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.

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

Nosec : 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.

Mikee Vee : This is why i hate private collectors.... let the scientists do the discovering so it can be officiated and done properly... we will probably never know the truth behind raptorex unless another specimen is found by scientists and can be traced to specific formations etc.

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?

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!

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?

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!

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

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...

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

Maximus Sparticus : This is just nanotyrannus all over again

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

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

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

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

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

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

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.

The Shamanite : The instance where science can't science.

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

Kanonier Söra : Do a video about the evolution of cats ^^

Steve Lawrie : The moral of this story is don't touch what you don't understand.

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.

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

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

Veggieboy Ultimate : 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

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

H Ĕ Ł P ? : The evolution of seals please

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

thes7274473 : Thanks a lot, amateur private fossil hunters…

John Lee : You guys make arguing paleontologists incredibly fascinating!

J R : Learned more from this than Geology 101 at a D1 university lmao Or at least I paid attention better to this. THANKS PBS!!!

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

Frank Kelley : What's up with monotremes?

Buildosaurus : I love the skull pin :D

יניב כהן : Hey people :) Can you do a video about how long does an extinction event last? Is it some hundreds of years? Thousands? More? How can we know if an extinction event is already starting?

Derek Koshiol : Wrong yet again, Eons: Relative Dating is actually when you go out with your cousin.

hans bakti : do about weird looking dinosaurs like Mononykus ! I'm still wandering what it's one-clawed front legs function..

Qwiet Ryott : Another top notch presentation Hun, Rocking braid \m/ \m/

Time Zone : Can you talk about koolasuchus An ancient amphibian that once patrolled the water ways of Antarctica and Australia

András Agócs : Geologists are brilliant. Such an underrated field.

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

Giuliano Batista dos Santos Giuliano : a video about megaraptor. how tiranossauroids evolved long arms in south america

Iddo Margalit-Friedman : One of your best videos ever. Thanks

Rob Card : click bait, not the host i was hoping for. will i learn anything? probably not because im moving on.

Vanessa Owens : I have an idea 💡🤓 First of all i love PBSEONS Second of all where the neck did Giraffes come from? Who was their earliest ancestor? There amazing ya know!
