The Oldest Creature You Can See without a Microscope? | Michigan's Grypania
Вставка
- Опубліковано 27 лют 2024
- In 1924, a boy was born in China who would transform the Michigan iron industry and discover what was, at the time, considered the oldest macroscopic fossil ever. This is the story of Tsu-Ming Han and Grypania.

Becuase I never met them I can't say for certain. But from the way you described him Tsu-Ming Han seems like the type of person who is able to see how fascinating the world can be if you take the time to look.
Thank you so much for your gentle handling of Han's life story. And, thank you for teaching me something new today, awesome.
I really appreciate you saying that!
I think an interview with one of his children might make some interesting content. Great work as ever
The very best history (and geology) lessons are those told as stories about people.
Tsu-Ming Han is a rockstar! he he... The videos are great. Makes me proud to work for Cliffs. The Sykes loads at LS&I in Marquette.
Thank you for sharing these stories. I have loved the UP all my life and love the stories you bring us. Keep up the good work.
Continuous learning in our own lives keeps things interesting. Generational learning keeps future generations with plenty of new things to explore.
Oh my! I live in Ish and Ive seen this placard and heard about this fossil find, but i didnt see or find any in deoth info about it at all. I am so so so happy you did and brought it out in such a great presentation!
Hey, thank you so much! I'm glad you got to learn about this, too! ☺️
@@AlexisDahl you do great work! You and Emily Graisile (I think I spelled that right) of The Brain Scoop are some kickass science presenters that I hope my daughters enjoy when they get a little older :) please keep up the great work!
Oh, man, thank you! I have a lot of respect for Emily, so that means a lot. (I also have one of her prints hanging in my office!) 💛
@@AlexisDahl well ain't that awesome :) my wife and I have sold cookies alongside the artist who made the Michigan print art on your right!
Love our community, love the UP, glad we've had our kids here, glad to learn about its past through wonderful content creators like you!
You help with communism when you leave out God/ Christ. China is trying to rewrite the Bible and your millions and billions of years narrative doesn't belong in a free society. ✝️
You must be settling into the UP quite nicely, I swear I heard you put the R in ishpeming.
...and he had an amazing smile! I think it's amazing that we find any evidence of something so old. Another great video.
With this, you've passed Emily Grassley and are on the heels of Bill Nye and Carl Sagan. Explaining science in understandable and interesting videos - science communications - is my new favorite micro-genre. I love the UP.
These just keep getting better. Thank you @Alexis, please keep em coming.
Thank you for this video! I shared it with my brother and sister who moved to Michigan. I really love the background story of Lao Han's persistent curiosity. Few understand the struggles the Chinese people endured during this terrible time in China's history.
Thank you for bringing this amazing story of Tsu-Ming Han to my attention. I hope others find this just as fascinating as I did.
I live in Michigan and enjoy the stories. I think this one could be a movie. Thank you.
Great little video, Alexis!
I have a large plate with several Grypania fossils on it in my personal collection.
I also have the article that went along with this discovery, including the interview with Tsu-Ming Han describing how he found the fossils.
Hi, where did you find your fossils?
I've been finding these fossils since 1970s as a child after learning about fossils around age 7, I watched the ground everywhere, finding these kind of fossils in stones of pale grey color like limestone or sandstone, most seen at gravel pits around Lapeer County and beaches everywhere. Few years ago I dug up complete property here near Buick City on north side of Flint River and found a stone with some near a large mass of what looks like a chunk of the lava iron rich stone spit out of Canada that was covered on this channel.
Great topic.
I always look forward to your videos! Thank you for them.
As a former geologist, and retired Presbyterian minister, I thank you for this very well presented video. Fascinating and very useful.
I love these history videos that you do. Where do you get your inspiration for them? Also have you considered a collaboration with Michigan History Magazine? They had a feature about the women working in lighthouses that I think you would enjoy.
Thanks so much! The inspiration comes from various places. 🙂 For this one, I had a friend mention Grypania to me in passing at some point, and things came together from there. Also, that's a great idea! I get that magazine but haven't thought about a potential collaboration with them. Thanks for thinking of it!
Super interesting!! Keep 'em coming! 🤗🤗
Excellent and considerate presentation about a remarkable man. Curiosity combined with an insatiable desire to learn is what drives good scientists. Combined with "outside-of-the-box thinking" is how great scientific discoveries are made. Thank you for sharing his story! Well done!
It is always amazing what a person can achieve in life if he doesn't care who gets the credit. Great history of a common man achieving uncommon results simply because of simple child-like curiosity.
Thank YOU so much for another excellent video!!!
New scientific discoveries frequently result in more questions than answers. That's the fun part of devoting your life to almost any field of study.
Love this channel! So interesting and I've lived in MI my entire life and had no idea most of the things you've taught me.
Keep up the awesome work!
Thank-you Alexis... Awesome story. The patterns of the fossils left by Grypania remind me of a famous type of stone in Canada called Tyndall Stone (used as a decorative stone in many buildings at the University of Saskatchewan and other government buildings in Canada). Tyndall stone has a mottling coloration thought to be the burrows of ancient worm-like creatures (but 'younger' than Grypania).
This is really great. I love learning more about Michigan. Thanks Alexis! 😀
Another great video! Thanks for the fascinating stories of people in MI !
Biographies are often fascinating. Maybe do some more? Keep up the good work.
A great story, about both a man and our earth!
Fabulous! Thank you for sharing.
I lived in Michigan (Ann Arbor) for about 20 years - went to UM and just stayed there. Love the state, love learning, and so glad I found your channel!
Alexis, A very nice video tribute to Dr. Han.
All the best from Traverse City.
Always love your videos, my favorite happy gal. More educational than what I got in school. Definitely could have used a teacher like you, with your enthusiasm for the subject.
Fascinating
Amazing I love your videos and your presentation thank you!
What a fabulous story! Thank you for sharing it.
Thank you what a fantastic story
I always enjoy your videos. It made me think of a story that I would like you to tell it’s about the first people to look for the iron in the upper peninsula. A individual named Marji Gesick supposedly pointed that out to them. I thought it might be an interesting story.
Awesome video. Also great choice in color for your nail polish.
Curiosity is probably the main driving force of human social evolution.
Thank you for providing another example!
Amazing story!! Thank you for sharing!!!
What a lovely story and amazing guy! Thanks for sharing this and now I do want to read more about him so thanks for the links as well.
Another great, interesting, thought provoking video. Got me interested enough that I will do some reading about Tsu-Ming Han, thanks!!
What a wonderful report, @Alexis!
Science. It's a process. Right on!
Great story!
Wow, what a story! Thank you for sharing it.
Great show, thanks
That was amazing! Well done!
So interesting! I love all of your videos. Thanks for making this 😊
the thing about what we call life is, it appears, that once it starts, it's not easily stopped.
that these ancient forms of it were found in iron oxide-bearing rocks, is a clue that there
*was* oxygen available, but it wasn't atmospheric. yet. that would come later.
10:30 "the thing about science is that it is a process[...]and sometimes we learn new things,
that make us change what our understanding of what the world is like".
very well said!
but anathema (I use that word for a reason) to those for whom the world *has* to be eternal and unchanging.
to suit a narrative, either they are telling, or have been, and perhaps, still are being, told.
You're amazing and I can't imagine the time spent on researching this so thank you.
Great history lesson! Keep up the great work. Cheers from the 920 of Wisconsin
i like your posts! thank you.
Incredible as always! Thumbs up 👍 to you Alexis.
I just found your channel today and have watched about 3 hours straight. Thank you, I've learned so much today.
Oh, my gosh, thank you for listening to me monologue for that long, ha ha! I'm glad you've been enjoying the videos!
I like how you were able to get my grandma's couch cover up on your wall be hind you. Excellent show!
Your grandma has a cute couch cover! 😂 Glad you enjoyed the video!
I sincerely hope that in your professional life you are a teacher...kids need someone like you to make things exciting so they WANT to learn.
Video after video, you pick obscure subjects and teach us why we should know about them.
Thank You, Alexis ❤
That's so kind - thank you! Believe it or not, this IS my professional life, ha ha, and I'm grateful for all the folks young and old who enjoy the videos. 🙂
Great info. Love your videos!
That was a cool story =) I enjoy hearing the stories you pick out. It’s fun!
Thank you! I appreciate it!
Love your questions and answers 😊
Another great video, love the history as much as the geology!
Keep up the good work I love all your videos this is great
Thanks, Alexis. I enjoyed this.
Great video!!!!
Awesome story!
Thanks for the video.
Love your lessons.
I love your take on the UP. in The early 70's I went there to ski in Marquette and Porcupine mountain. That was cold 35mph wind off superior but I went there to ski. In Marquette I was amazed by the amount of snow. It went to the tops of a 2 story house and there were cutouts for the sidewalks and driveways but no snow on the roads. They trucked it out of town. I met people from Escanaba and at the time they told me they got 350 inches average snow. You should lookup how the copper was discovered by the Indians digging holes all around finding copper on the surface. Ah adventure and youth. I'll stay in NW Ohio haha.
If Grypania is a colony of prokaryotic cells, then there are fossils 1.5 Gyr older from Eastern Australia called stromatolites with the same general characteristics. However, if Grypania is a multicellular eukaryotic organism, then yes, this is a very old macroscopic form of multicellular life, perhaps the oldest.
Thanks--this was 100% delightful. {Looks like Anabaena, a simple photosynthetic prokaryotic algae that is billions of years older}--but if Grypania seems to be super-early eukaryote, that's wonderful--Way to find stuff, Tsu-Ming Han!
Beautiful!
Great story
Oh, yeah, subbed!
Love how you explain that science is a process, that somethings we might really know, others not so much. Also… the importance of being curious. Always stay curious…. On a side topic… do you ever travel downstate? The saginaw valley is quite diverse in its mineralogy, there is also the salt deposits and mines, and there are the petroglyphs in
Sanilac county, for a few interesting topics.
OK, you and this story are the straws that broke the camel’s back: I’m finally going to visit the UP this summer!
I live in Marquette Michigan upper peninsula and their is so much history so much awsome history about DA U.P and also lived in ishpeming for years only 15 min from Marquette this is awsome
First prokaryote was the 3.5 billion year old cyanobacteria that started our Oxygen cycle. Found in the stromatolite beds in Australia. My biologist professor Lynn Margulis remarked to me that she was curious about why they didn't evolve. We didn't know about Grypania then, but algae seems to have reigned supreme for at least 2 billion years before prokaryotic life could survive.
Thanks
Michigan rocks!! !
Correct me if I'm wrong, but if it was an algae, and thus photosynthetic, wouldn't it have been taking in CO2 and producing oxygen?
Dr Stefan Lanka has done some interesting experiments that might get you thinking
Very interesting! I have close friends in both Negaunee and Marquette- fun to hear how these towns/ cities made 'history'.😊
Maybe they took in CO2 and realeased O2 like the early stramatolites ! Pretty intriging that was found in the U.P !
Love all the enthusiasm in these videos! 😅 I have never been convinced that dating rocks, or carbon dating in general is particularly accurate. These people are just taking wild guesses, in my opinion. Great and interesting content!
As a 6 year old I watched boxing with my grandfather and heard about WW II from my uncles. One was a POW of the Nazis. I think I’ll be ok with fossil violence.
So he found our great x1,000,000,000 grandpa?!
I see these in RI, but I doubt they're very old.
Am I the first to mention how much you and Mark Rober look alike?
Ha ha, you are not! It's something I always take as a compliment, though. 🙂
🤔
Stay away from my rocks nerds !!
You might consider a video on the original survey of Michigan in the UP. William Burt and the invention of the solar compass. Douglas houghton. Lots of it ties to mining.
the 'fossil has to be older than the rock for the rock to have formed around it. rock cannot really be dated.
Okay, I simply can't cram more stuff in my head, apparently, without something else falling out. So help me, please. I thought those massive ore deposits form because there was enough oxygen to form water-insoluble iron oxide. So, there would be a fair amount of oxygen. Or, not. Please drop a reply so I can lose some other, older, and hopefully less interesting piece of information. Thanks!
Thanks for the Great video!! Have you studied the great unconformity? A possible missing 1 billion yrs of earths history. I LOVE GEOLOGY lol
It would be nice to hear about petrified tamarack forest.
R.I.P. Han.
Alexis, your videos are always interesting and well presented. I’m no scientist, but what I got from this video might be that life on Earth got its start in the U.P. 👍🏼😃
Have you investigated the crude oil microfossils found in the Nonesuch Shale? 😮
