The Paleozoic Era has always been my favorite Era, I have always imagined on traveling back to the carboniferous period back when oxygen level were 15% higher and ride scorpions the size of wolves while listening to Marty Robbins "El Paso" just pimping around the carboniferous swamps
Haha you and I have very different dreams. I, for one, am very glad we do not have scorpions big enough to ride anymore lol. But I am glad you enjoyed the video! :)
Thanks so much for this video!!! It was soooo informative and it helped me out so much with an 8th grade science project I was working on. This video made everything so clear and I can't thank you enough!!!
Your videos are fantastic! Just found you by chance today and I keep watching them.
Thank you! I am so glad they are helpful!
Bravo.....very crisp and informative, doing a great job and helping in the understanding of basic concepts to geology students around keep it up .......
Thank you so much! ;D
Watched just out of pure interest. Super awesome! Thank you!
So glad you enjoyed it, thanks for the comment! :D
My very favorite educational youtube channel.
Good and informative presentation.
I am always fascinated by how scientists have these theoretical landmasses and how they formed. I wonder how they are able to guess where Laurasia was or where Gondwana began.
Interesting stuff.
Thanks for this vid!
In terms of where the land masses were, you can look at climatic signatures in the rocks/life on the landmasses. Easy to see Gondwana spent a lot of time around the poles due to abundance of glacial deposits, lack of marine fossils; and the opposite is true for Laurentia: lots of marine rocks and fossils, lack of widespread glaciation.
1 correction. Turtles are actually diapsids just like all other extant reptiles. They’re used as an example of the anapsid condition today because they lost the holes in their skull over time, but they’re not actually descended from ancient anapsids which have no living descendants. Aside from that little nitpick, excellent video!
g-d Dylan is a Paleontologist. My favorite Era. Thank geo Girl. I live in Denver, CO.
Geo Girl is totally inspiring! ❤🎉😊
Somehow I'm a year late finding this great video (a mere blink in geologic timescales). I love the way you match plate tectonic events with biological events. Thank you.
Of course! Glad you found it helpful :) Thanks for the comment!
Good presentation. Thanks.
hey Rachel, that paleozoic paleogeographic summary is awesome! love visual charts and graphs with geologic events over time. super cool. is that slide downloadable? do you have one of a geologic graph but to scale with geo and bio events on it?
Love your videos :)
Thanks Patrice :D So glad you like them!
I think I’ll watch this video again. I ❤️ GEO GIRL.
This is one of my favs!
Great video thank you.
You're welcome! Glad you liked it :D
I suppose, Rachel, that if you could've been able to time travel you'd visit the Devonian to do some fishing😉😁.
I think your Alleghenian pronunciation sounds good. Al-eh-gain-ee is how I've heard the area of Appalachia called.
I love the tiktaalik bois
This girl is computer generated. I think it is modified software for scientific translation that is at the core of the interactive text generation spambots so it all fits together to be able to make this beautiful channel. Its like we are living in a paradise. This is the age of study. Don't waste it.
Haha, I am glad you think I am doing a good job putting all this information together:) I have such a fun time doing this, so I am glad it is both appreciated and helpful! ;D
Great video! I can talk about the Cretaceous Western interior seaway (wis) all night!
Till the sun comes up 😊😊
Thank you! I agree, the Cretaceous interior seaway was so incredible! I have some more recent videos about the Cretaceous if you want to check them out ;D -> th-cam.com/video/RyebbB0_xhs/w-d-xo.html
-> th-cam.com/video/Rz4n28PQ4nU/w-d-xo.html
thank you.
I like the way that you organized this video but i found it hard to process information with as fast as you were talking. I felt like you were speeding through information but I am super interested in this topic and trying to learn more for my science class
And i don't mean that as an insult, just trying to provide helpful feedback :)
Thanks! I appreciate the feedback! :) Best of luck with your class ;)
Love this ! but because i'm from poland I need to know the polish and European mountains 😭
Very nice loved it love from India 🇮🇳
So glad you enjoyed it, thanks for the comment and support! :D
Does this video sound a little fuzzy?
Probably haha, this is one of my very old videos that I did with my internal laptop mic🤣 Don't judge me! I was new to this LOL
A geologist Mum, Rachel, I guess that makes you a chip off the old block😉😁.
Super ❣️
Thanks so much! I am glad you found it helpful :)
Love ❤️ evolution I know this period and they said the Cambrian animals are the ancestors of humans heard that before and fish 🐠 is the ancestors of humans
Favourite Era.
It's an exciting time isn't it!?
Beautiful colour of your t-shirt 👕 and you
Love from INDIA
Thank you! ;)
So nice 😍
Can i get you Instagram
Can I ask? Where did life exist during the early part of the paleozoic era?
What a great question! Actually, life was only (or mostly) in the ocean in the Early Paleozoic to our knowledge. It wasn't until later in the mid Paleozoic that land plants evolved and made the terrestrial realm more habitable (which I mention in the early Paleozoic video: th-cam.com/video/oPX0rBTYG8g/w-d-xo.html), which is also around the same time that animals began walking on land (tiktaalik transition, which I mention in the earth history song here: th-cam.com/video/2LiS6E98hRI/w-d-xo.html). However, it is possible that bacteria, archaea, fungi, and even non vascular plants like mosses could have made the transition sooner, but likely had to stay near a body of water. So I guess that true answer to your question is we are not totally sure, but the general consensus is what I mention above. Hope that helps! :)
scientists have attributed the eyes of a trilobite to be, "the greatest living lens. The trilobites' eyes were different than most creatures' eyes because they were composed of materials that could be studied even after being fossilized. Most creatures' eyes dissolve after death: tilobites eyes did not. When scientists began studying these eyes, they were amazed at what they found.
Humans have only one lens in each eye. But trilobites had two lenses in each of their many eyes. In order to see clearly under water, it was necessary for them to have this "double lens" in each eye. If their eyes did not have two lenses, things would probably have appeared distorted. The scientists discovered that the lenses were so perfect that there would have been no distortion at all. Since trilobites are considered to have been one of the first creatures to evolve, it would make sense (from an evolutionary point of view) to suggest that they possessed fairly primitive features. Yet the eye of the trilobite is anything but primitive! How could this "perfect eye" be found in an "early" animal like trilobite? And how could it have been so well designed?
What do you think?
It wasn't one of the earliest things, to evolve, nor was it 'designed'
We humans have no sense of the scale of deep time.
@@ericvulgate7091you "know" what happened...😅 of course
"Don't know if I'm sayin that right .... But it happened...."😂
Science without levity is a curse.... the depths of which are only matched by the heights attainable with science as an ally....
Religions are proto sciences.... In the separation.... Humor was lost. And EITHER without levity is counter productive. Faith in the fact that, despite our inability to ever know some things, nevertheless, they happened. Faith in the fact that it's all here and all works.... Is by definition faith in creation....
Idk why or how is all here or why it all works.... Even if I've discovered the GUT! And run it through computing technology millions of years in our future......... I still don't know how it all works, or why it's here....
Have faith. Make humor intelligent again. Acknowledge our limitations and embrace the fact that even if no human ever wrote a letter or cracked a book, We are here and we can laugh at ourselves.... If we're smart....
Come over some day maybe play poker 😊❤️
Oliver, you must have heard that saying from my mom too! very good ;)
I just learned COSD MPP (like "caused") Triassic, Jurassic, C-T. A bit obtuse but I learned it pretty fast
The Paleozoic is way cooler than the Mesozoic, everyone is all about them dinosours, man, screw dinosours 😄 the Fishapods is where its at. Where's all my Sarcopterygii, Rhipidistia, Tetrapodamorph, Stegocephalia people at? Y'all know what I mean, fu*king Darwin fish man! 😎 🐟🦎 Devonian, Carboniferous! Bada boom, bada bing, bada brachiopods!
