Foraminifera (Forams)- Invertebrate Paleontology | GEO GIRL

[@GEOGIRL]

Hey guys! I have a correction about the hyaline forams, they are not actually glass (silica) they are just glassy textured calcite! My bad, sorry for the confusfion, hope this helps, and thank @Kyron 66 for catching my mistake! ;D

[@victoriaonyinyechi5823]

Pls can you make a video on ostracods

[@aadilbhat4309]

Love from Kashmir ❤ Very nicely explained

[@JoesFirewoodVideos]

Never heard of these creatures so I guess it’s better time that I learn! I ❤️GEO GIRL

[@GEOGIRL]

You amaze me! I always thought the only people who would watch these types of videos would be students trying to pass an exam, but your curiosity about these topics and desire to watch these videos just makes me so happy! ;)

[@njm3211]

Nature is even more amazing than i could possibly imagine.

[@davids82605]

Thank you VERY very much for all your videos! I went into mathematics and physics in my cursus but paleontology (and nature in general) always have been one of my greatest interests, and with you I feel like I am taking real paleontology classes - without all the harrassment of needing to pass a degree at the end ;-D I love the very wide list of subjects you depict, each of your vids I watched helped me gather and organize my own knowledge into more structured and chronological events and facts. To give you a basic example, I always knew since childhood there were multiple mass extinctions, but only since one of your vids I saw a couple weeks ago was I able to precisely pinpoint the others apart from the two major and most "popular" ones! Of course I could have forced myself to learn all by myself, but your vids made me WANT to know. And keep.

[@GEOGIRL]

Thanks so much for the comment, I am so glad you have found my videos helpful and enjoyable ;D It makes my day that my videos made you WANT to know these things, that is awesome!!

[@SuperRl7]

Can I just say how thankful I am for your videos !!!

[@GEOGIRL]

Can I just say how happy I just got by reading your comment !! Thanks so much, I am so glad you find my content helpful! 😁

[@michaeleisenberg7867]

Geo Girl, Thank you for this and all your videos--especially the organic/life topics. I love them. I was a bio major at UO, '79. Today, July 4th, I was watching Foraminifera while at the gym, with Wimbledon on the elliptical screen--always weights first! Which ties into your blouse. Stars 🌠. 4th of July 🚀. I like it. It looks good on you. Running beneath the surface of this video and all your life form videos is the tremendous and dedicated work done by all the scientists and biologists who study and codify all these extinct animals. It is mind boggling the intricate anatomic detail including the myriad byzantine Greek anatomic terms. What is even more inexplicable, in my mind, is how many fossil hunters and paleontologists are there in the world, how many years have they been doing this, and how miles have they covered? Nice shout out to your TA! Best Wishes, MikeE

[@tomascorrearestrepo8038]

An awesome video, thanks for making this knowledge available for all of us in a fun and instructive way.

[@Inaparadigm]

I was curious about forams and found this video! Thank you!

[@GEOGIRL]

You're very welcome! So glad you enjoyed this video, it's one of my favs. Gotta love these tiny organisms! :D

[@yayamal1]

I will recommend this video for my undergraduate students

[@GEOGIRL]

Oh my gosh, I am so glad you think it will be good for your students :D That is music to my ears, thank you!

[@kyron6643]

I like your videos, and think they are informative. Something to check, hyaline forams are not made of silica, they just have a glassy look due to the arrangement of calcite crystals.

[@GEOGIRL]

OMG, thank you so much for pointing this out! It must of been the word glassy that tripped me up, I will pin a comment so people know. Thanks again, I really appreciate you catching this!

[@purplesky7893]

great video! this channel is underrated.

[@GEOGIRL]

Thank you so much! You are so sweet :D

[@liamhackett513]

You should be getting more views and probably will. Have been looking at earth science stuff on YT during lockdown. Oxford natural history do great lecture s and talks. Your work complements it spot on . Great channel .

[@GEOGIRL]

Thanks so much! I started it just to post the lectures I need to make for my students anyway, I never imagined people would watch it for fun, but I am so glad that some people are! :D

[@jy6721]

Thank you so much for this video. Ever since I listened to Dr. Joan Bernhard talk about these little critters while she was on EV Nautilus last year I've been obsessed in wanting to learn more about them, but unfortunately it's hard to find any text on them at the library, in my area at least (Books be expensive). They are so cool, and honestly I had no idea existed until just last year. :')

[@GEOGIRL]

I know right! You'd be surprised how many people have no idea they exist! (And yes, unfortunately books do be expensive lol)

[@BadmaaZorigt]

outstanding. thank you very much!

[@mi4208]

But how they develop calcite shell I mean that they excrete something or they just take it from environment

[@GEOGIRL]

Yes, they excrete their calcite shells (or tests) by using ions that are readily available in the water they live in. Calcium cations (Ca2+) and carbonate anions (CO32-) are present as dissolved ions in the ocean, these organisms utilize these ions to precipitate their skeletons. How to they take the ions from the environment and put them to use? Well it is the same way we eat food and use some of those nutrients/energy to build our own skeletons when we are growing as humans. For example, the calcium we consume will help build the Ca-phosphates in our bones, this similar to how marine organisms grow their own skeletons, it is just different in that theirs is on the outside of their body. Hope that makes sense! ;)

[@williammillerjr9028]

This may be dumb ...but.... Were these things fleshy/squishy at some point and hardened or fossilised over time?

[@cerberaodollam]

My European brain: since the heck when is a football shaped like that?! Oh, wait...

[@GEOGIRL]

Hahaha! Oh my gosh, I didn't even think about that, my bad! I should've thought about my international audience given you guys make up over half of my audience. My american professor taught it to me that way, so that's what I thought of in the momment haha. But you can also think of them as looking like little rice grains. ;)

Hello! thank you for your video ! I'm studing paleo too and your video are really helpfull :)) I'm french and I have an english presentation ( that why my english is so bad lol), I want to know if i can take some of your picture in this video for my presentation ? Have a good day !

[@GEOGIRL]

Hi Sarah! Thanks for the comment, I am so glad you found the video helpful :) You can absolutely use the pictures for your presentation, the image links are all in the video description ;)

[@sarahgermain4339]

@@GEOGIRL thanks you 🥰🥰

[@raysalmon6566]

*University of Pennsylvania* paleontologist Edward Drinker Cope for example, stated that embryological development occasionally accelerated to create new stages of organization. Some of the new stages related directly to environmental pressures: the organism consciously strove to adapt itself by means of its "growth force." Other new stages reflected more formal patterns of development. Cope also integrated his evolutionary views into a broad, religious philosophy. A universal consciousness, he believed, guided evolution and ensured its progress. 439 UHM class Darwinian Revolution

Life of foraminifera??

[@DaveyBamford]

Geo girl, I can’t find your diatoms, radiolarians and coccolithophores video

[@arpittomar9945]

Can you bring a presentation on radiolaria? I need help with it.please😊

[@GEOGIRL]

Haha, you are the person I needed. I was slacking on making that lecture because I was like, no one is asking me for that topic so no one is going to want to see it, but now here you are! I will get working on it now ;) If you want a little bit to hold you over, this video has a tiny bit about radiolarians in it, just skip to about 9:45: kzbin.info/www/bejne/m3y6lJippJ2Iq8U

V. Good, do you have video about how to prepare foraminifera species from carbonate rocks espicially limestone

[@motasemobaida9107]

I am studying master degree on foraminifera and i need help, on preparation🤗

[@GEOGIRL]

What do you mean prepare? You mean how to isolate the Forams from the limestone?

[@motasemobaida9107]

Yes isolate by picking friend🙂

[@GEOGIRL]

What do you mean picking? Sorry, I am not a foram expert😅

[@motasemobaida9107]

I can't find the steps how to isoalte forams

Please answer: Question: Largr Benthic Foraminifera became abundant in diversity and quantity since: (a) Cretaceous (b) Eocene (c) Oligocene (d) Carboniferous (Only one option is correct)

[@GEOGIRL]

Oh, I am not actually sure but I would have to go with Carboniferous since I believe that was the first time they diversified (they did again later, but the carboniferous is particularly known for large fusulinid forams). Hope that helps ;)

[@pratyushkumardash4410]

You are saying they are football shaped, but they seem more like rugby shaped if i am not wrong...

[@GEOGIRL]

Yep! Absolutely, sorry I meant american football, but should've been more clear. Rugby is a great way to describe their shape ;D

[@freethinker1281]

Please tell me answer: Question: Foraminifera were widely distributed in which of the following periods ? (a) Cambrian (b) Carboniferous - Permian (c) Tertiary (d) Jurassic (Only one option is correct)

[@GEOGIRL]

Oh gosh, I hate to say Carboniferous again, but I am going to have to go with Carb-Permian since they are excellent index fossils for that time range, hope that helps ;)

[@freethinker1281]

These are Indian university questions

All the Cretaceous planktonic Foraminifera extincted, however the relation between heterohelix and Gumbelitaria cretacea is not confirmed and never support evolution...

[@GEOGIRL]

Oh, interesting! I will have to go look up those as I am unfamiliar with those exact species, but thanks for sharing, I appreciate the insight and will look into it! :)

[@a.randomjack6661]

"the relation between heterohelix and Gumbelitaria cretacea is not confirmed and never support evolution..." Rhetorical question: What do they support; Creationism or giant aliens that built the pyramids using tweezers?
