What We Learned in Paleontology in 2021 

Thank you for your time and I hope you're feeling better! This video was very good!!

really appreciate your time and making these videos thank you so much

Definitely 2021 like many other past years was a great one for Paleontology which is really great

So many useful links in the description! Thanks!

Crazy to think life could rebound that quickly after the kpg extinction

I don't think it was just the forests taking over from the grasslands because mammoths survived every other warm period. The difference with the most recient warm period was HUMANS. I think it was HUMANS that provided the final insult by hunting & fire that pushed the mammoths & many other large ice age mammals to extinction. Everywhere MAN went, large animals died "shortly" afterwards. We continue to cause the deaths & EXTINCTION of wildlife & plants.

Okay so the young of large dinos filled the space for mid size dinos? Sure thing so where are the skeletons of those juvenile dinos? In other words the theory actually fails to explain the missing fossils.

15:40 I have a hard time buying that juveniles of a giant animal can out-compete the more experienced adults of other animals.

Ooof, feel better soon.

Please consult all paleoz - could we make a vid on how the replica skeletons are built? Makers and Virgos need to know. Someone has to do it this year, this season.

The comment you said about the madness losing grasslands is not comprehensible it was still a lot of grasslands woodlands didn't take off big until the colonists brought the earthworm to North America in 1615

I just don't feel like a comet is convincing. I'll need more papers backing that one before I can buy it

Great video

Fascinating,you could compare these early life studies,to current idea's and hypothesise related to asteroids and other planet samples.anton petrov,I think has these other world/mineralogical/atmospher/life studies in simple language like your presentations,thanks,and get well soon

So which ones for January 2022 are you going to cover for your channel?

@20:25 + reminds me of that group wanting to bring back the Wooly Mammoth up in Siberia. Makes one think, anyway. Edited to add: @22:30 - WHAT?? Has no one ever watched a little chick, a week or two after hatching, flapping their wings and hopping around?!? They don't break off the chick, even though they're not strong enough, YET, to hold the weight of the chick! I've GOT to read that paper, because either they're IDIOTS, or you're misunderstanding what the paper said. 2nd edit: I read, really carefully, the paper involved in the wing size & strength. NOWHERE in that paper does it even remotely suggest what you said about "snapping off" of wings! You COMPLETELY misunderstood the study. Had their bodyweight outpaced their wing size and strength, they would NOT be snapping off their freaking wings. They would simply NOT have been fully flying. They would just be in the fly-late category! It really clearly states, even in the abstract, the following: "A ‘flap-early’ model proposes that hatchlings were capable of independent life and flapping flight, a ‘fly-late’ model posits that juveniles were not flight capable until 50% of adult size, and a ‘glide-early’ model requires that young juveniles were flight-capable but only able to glide." Now, WHAT in that, or in anything anywhere else in the paper, leads you to think about wings "snapping off" if they're underdeveloped with the age of the critter? I've seen WAY too many actual examples of wing development in multiple species, and that's simply NOT how it works. 😐 At all.

You should define more clearly what 'equitable science' means. If it means access to specimens, or rather means keeping specimens to be discovered, preserved and studied by the researchers from the (let's face it, temporary) political/geographic boundaries where the specimens were bound in rock.

Looks and sounds better. 👍 Overlooking the long johns.

Since you are maskless I feel unsafe viewing this video.

Can you plz do a vid and explain how you know that its billions of years. Sience always trhow around age like its a Date on The bones like a carton of milk. For me it fell like bs. .

The verb root of predator is prey, not predate.

Wait, Why is it our fault you caught covid 😂 I thought you were wearing your mask.
