If you like our stuff, and would like to help us keep making it, please consider chipping in over at patreon.com/YDAW, or taking a look at our products at www.etsy.com/shop/YDAWtheShop, or by buying Steven a coffee at ko-fi.com/ydawtheshow . All proceeds go back into making the videos you see here!
So glad you could join us for Paleo Rewind! It's so exciting to have had the chance to take part in this project with so many TH-camrs who have inspired me to create my channel!
Y'all rock dude!
So thrilled you are part of this again! Great video as always guys!
My favorite dino related chanels are ALL in this year~ And this is one of the Best. Congrats and Amazing work!
I don't want to tell you guys what to do with your time but a monthly news summary shuch as this would be great on this channel :)
Good job!
If that's something you're interested in, at least one or two of the other channels involved in PaleoRewind this year already do monthly paleo news videos! Raptor Chatter is a good one.
Thank you for your contribution to PaleoRewind. Merry Christmas! 🎄🦖
Great work on the video y'all. Your animations are always so good for explaining these topics.
I remeber reading a computer modelled analysis where they took a little rattite bird, put it on a treadmill them made a simulation of it walking and running. Then reconfigured its body shape to be that of a coelophysis and then moddeled it witht he tail not moving, and then ran some simulations of it moving. The tail doing a figure 8 movement was like 40% more efficent than not moving. Although this was about balance rather than tendon power, so i think that when you throw a heap of elasticy tendons in there efficiency is going to be higher still.
always love when a YDAW vid drops and shows up on my feed :) I thank you for the details we never seem to get anywhere else.
doesn't matter what dino you're talking about, i'm always fascinated....even when it's not "truly" a dino..... (still waiting for an episode on mosasaurs!!!! yes, i know they're not technically dinosaurs!)
Excellent video. It feels weird that another year has already gone by.
Also the description weirdly says "We tackle the month of June with a review of some of its most interesting reveals."
Oh, derp! Thanks for pointing it out, fixed!
Copy & Paste from the June 2020 Paleo Rewind?
I love this channel. Seriously in my opinion this is one of the best dinosaur channels on the site!
I couldn't pay attention do to that sweater I want it so much lol it is the coolest 😎 🤣🤣
Baby long necks with amazing variating scales~ So cute!
"..and some math I won't pretend to understand" hehe
Thank you so much, I love these Rewinds and I'm very excited you guys joined in! My favourite show on TH-cam.
Thanks for sharing!
love this channel so much, really great work Steven!
Great paleo video as always, YDAW! Very well done! Also, Merry Christmas and Happy Holidays everyone! :D
This is really cool man!
Happy holidays!
Well this was pretty awesome and I love it
Thanks for the contribution to the rewind !
Truthfully, I don't think i ever watch any YDAW video yet. But you sound like an interesting guy ; i'll check them out soon enough !
Ps : guys, go check April Part 1. Jimmy's a funny guy ; and made a great vid too !
this deserves way more views
I love the outro
This is cool
New ydaw hype
Man... Dinosaurs are cool.
Could it have been a predator trap in the center of a home range, like we see with the Rancho La Brea Tar Pits?
Paleorewind 2022 is December Christmas Eve.
Personally, Tyrannosaurs being gregarious makes sense. Just look at pre contact canids. They were forced into groups because they were getting our competed by cats, who could apply 3 points of contact during a fight, using their rotating elbow joints. Canids can only establish 1 point of contact, their mouth/head. Very interesting
Cool!
Hehe hey… I’m here to ask your about the bone wars…
Also, can you do a Guanlong!!!
Can you please do Lambeosaurus Lumbi? (Pardon my spelling)
I want to know more about how Hadrosaurs chewed their food so well.
Huh very cool
Can you please do Yutyrannus Huali in the next YDAW episode?
Lol
Wow, evidence that non-avian dinosaurs weren't mindless killing machines and could easily coexist and exhibit gregariousness because they were living, thinking, sentient animals? What a surprise! /j
Sorry, I just have to be sassy about this occasionally lmao. Awesome find, what a great year for palaeontology!
"... and some math I won't pretend to understand..." 🤨 😄
Welcome to the club! 👋🙂
Great video! So, since I have nothing else I can offer, here's a like and comment for the Almighty Algorithm for you.
Im almost never this early
Any Plans for doing a YDAW on pachycephalosaurus?
MEI KMRIIIIIIMAAAAAAAAAAAAAAAA
I didn’t see a paleo rewind from DWABA
So my bday is in April and i have stuff that has to do with my ear wow this is suspicious
🦕!🦀
Large ornamental scales on a diplodicus? WWD might have got it right!
Sad you didn’t mention Llukalhan Aliocranus
It was described in the first half of April
Lake Kivu in central Africa animals that come near are at risk of being asphyxiated due to explosive events of toxic gas. Maybe this could have happened to this poor dinos?
There’s no link to the previous video…
Fixed!
@@YourDinosaursAreWrong Thank you!
Maybe I'm blind, but I can't seem to find it
Where's April part 1 ?
Dinosaurs Will Always Be Awesome posted it this morning: th-cam.com/video/8IxJVlm4XyM/w-d-xo.html
