One of the paleontologists at my university is an expert on conodonts and I studied under him for a while and took a paleobiology/invertebrate paleontology class with him. He is crazy about conodonts. They are like his favorite animals ever. I think that they are pretty cool too. (I am a geology major with emphasis in paleontology.)
To me, those "teeth" (4.45) look more like gill arches, the tiny bone like things in fish that are needed to let the water flow through thin blood vessels in order to absorb oxygen from the water. Without them, gills would collapse and the fish would "suffocate". Perhaps, in these fish the gill arches were particularly sturdy, enabling them to survive the eons and help us index the paleozoic.
Wow!!! I am shocked that I had never heard of these fossls before. I can't recall them being even mentioned in my paleonthology course back when I was going through college. Thanks a lot PBS Eons, I really love your high quality content! Btw, could you make a video about Cycads, those ancient palm-like plants that refuse to go extinct as Angiosperms now rule the Earth?
I love this show so much, more than any other. Every Sunday night and Monday morning I find myself thinking about fossils and ancient life forms, in anticipation for the next Eons episode. Thank you all for making each week better!
Thank you for doing this! Yep. They are so distinct that geologists will often use them to define upper and lower geologic boundaries. Like you said, they make great index fossils.
Every single episode astounds me. Seriously, I knew paleontology was cool, and you guys make it way way more interesting than a textbook! I especially love these episodes that unravel a mystery - it makes the answer that much more satisfying. Thanks for another fantastic story!
Bug-eyed is a figure of speech for oversized, staring eyeballs. People talk about 50s movie monsters as bug-eyed not because they had compound eyes but because they had oversized eyes.
I worked with conodonts for over 30 years before I retired. Mostly it was dissolving several kilos of limestone per sample in dilute acetic acid and taking a month or more to get a sample through processing to get a date. In the 10 years or so before retiring our mapping programs moved into areas with very little limestone and monotonous deposits of deepwater shales and cherts which had been dated badly as it turned out using occasional scrappy graptolites. I took to sectionong the cherts and later the shales to look for conodonts and found them in abundance. instead of kilos of sample you only needed a less than fist sized sample slabbed parallel to bedding and sectioned till it was semi transparent. I was finding hundreds of elegantly preserved specimens in paper thin sections and the larger more fragile elements were more complete than the same ones extracted from limestone. Best of all if you needed a quick result you could go from hand sample to completed slide in 1 to 2 hours. They enabled the precise stratigraphic mapping of large swathes of previously poorly mapped country, provided important large scale structural information and helped to precisely date significant mineral deposits and mineralisation events.
Very cool. Did you work for a private industry or for a university? I'm ignorant on this topic, but, from the video, it sounded like this could be a commonly used tool for the petroleum industry.
@@charlesbrowniii8398 In Australia for my state (NSW) geological survey. They are used overseas in Petroleum exploration but most of the sediment they are found in in Australia are too old and cooked to host petroleum deposits. The Colour Alteration Index mentioned in the video is used to determine the temperature ranges the sediments have been exposed too so it is a useful petroleum exploration tool.
@@garydargan6 My daughter was supposed to be in your territory last spring, but that all got canceled with Covid. Hopefully you won't have such a bad fire season this coming year. I live in the eastern part of the state of Washington, right in the path of what was the Lake Missoula floods - lots of interesting geology, but aside from some Precambrian rock poking up in a couple places, most of our geology is less than 17 million years old.
Every episode I'm all like, "Yeah, but it's not an episode about snowball Earth." And then I'm all like, "Wow! Conodonts are the coolest! I didn't even know they existed!" I love y'all.
We currently have no proto-bat fossils from before they already had flight, and we don't even know what basal bats looked like because their relationships are still highly disputed. But this is something I want to see. And sorry Tinman, but that theory has been discredited. The only link was that there was a protein found only in primates and megabats, but bats and the rest of laurasiatheria have far more in common genetically.
I love what you guys are doing. I have always been curious about the separation of Australia, and the divergent evolution that occured there, and would love to see a video about that.
Woohoo, a group of animals I had no idea of, before! What do Ceticarids, Titanichthys, Leedsichthys, whale sharks, and baleen whales have in common? They're filter feeding giants, but all from totally different lineages. What's known about this niche; is there a correlation with the presences of gentle giants in the oceans and certain oceanic conditions? Or is it assumed that the filter feeding giant niche is always available throughout earth's biological history?
Hi Kallie!!!! We went to grad school together at UM. Was Megan Rosenblatt's roommate. Vicki Balfour (Dr Balfour now).....teaching middle school and LOVE your video :)
I love this series and I always look forward to the next one. I would love to see more videos on life before the dinosaurs... Maybe like more on stem mammals or early amphibians. I find these times fascinating!
I love it when educational videos explain how and why knowledge gained is useful! Obviously, learning just to learn is fun and valuable; but it makes some topics easier to engage with when a person (especially a student) isn't typically interested in it.
It would be interesting to talk about the various endosymbiotic events (I don't know if you've talked about any/all of them before), like the integration of mitochondria, chloroplasts, and the like. Interestingly a more recent one is aphids integrating Buchnera (a type of bacteria) into specialized compartments which obviates their need to excrete nitrogenous waste.
Conodonts were wiped out by an extinction level event brought on by a quick rise in atmospheric carbon dioxide levels, and now Conodonts are helping us locate petroleum so we can create our own extinction event by raising carbon dioxide in the atmosphere. How ironic...
Slick. I did not know that. Back in the day when I was attending college, some of my pals were taking Geology courses (yes, they wanted to get BS degrees in Geology), and some times they'd would go on and on about these little fossils in their textbooks or have been looking at under microscopes in their labs. At the time I sort of tuned them out as they weren't discussing the lovely chemistry associated with herterocyclics or the latest in tosylate chemistry.
Fungi would probably be best as its own episode unless talking about the symbiotic relationship between fungi and plants as they are close relatives of animals not plants.
A video about subduction and the great uncomformity. Is it possible that another intelligent life, like humans, could have arisen or is there evidence to refute this or support this? Love your channel btw. Thanks guys.
Thank you a loto for keeping up these amazing videos! It would be really interesting if you explained the differences between nimravids and machairodonts.
I like it how every single video from this channel ends with the extinction of the species presented. Mass extinction definitely is your business, PBS EONS.
When I was taking upper level paleo courses at UC Berkeley in the early seventies, conodonts were still a big mystery. Glad to hear that they've found an animal for them.
Awesome video once more, thanks again! Maybe one of the next videos could shed some more light on the bivalves? IMO really one of the most interesting groups still alive today. And their fossils are also often used as index fossils for specific time periods.
I don't know how they evolved, but I know that they evolved from arthropod gills. I think the spiders' silk-making organ also evolved from gills. I recommend reading Sean B. Carroll's Endless Forms Most Beautiful!
Guilherme, that is only a theory (the epicoxal theory). There are several theories on how wings evolved and so far the most supported theory is the endite-exite hypothesis. Much more evidence is needed from fossils.
Yeah, the origin of insect flight is an interesting subject of inquiry and speculation -- especially because its physiology and mechanics is not only so different from that of avian and mammalian vertebrate flight (birds and bats) but also because it's so different between different insect species (how houseflies fly is different from how butterflies fly as how dragonflies fly and so on). One big question about the evolution of flying insects I have is do all flying insects share a common ancestor as the first such insect to evolve that adaptation, or did insect flight and wing anatomy/physiology evolve independently between different species of flying insects at different times in evolutionary history? My dad might likely know the answer (if there is one, that is) as he's an entomologist.
Isaac The Destroyer of Stuped I think, based on my own speculation, that when they first arrived on land winds may have played an important role as natural selection. Since they were small, only the ones with some kind of pre-wings, i guess, could thrive better.
I have not heard of this method of dating the past. I am always fascinated about how scientists take a few clues about the past and make sense of them. I am so happy you launched this channel. Kallie is one of the best hosts on UA-cam.
Conodonts indeed were abundant and useful, but I'll put in a plug for diatomaceous earth, which is composed of the silica remains of diatoms and has dozens of uses including water filtration and scouring powder.
So much interesting info from PBS Eons.. so captivating.. sometimes makes me wonder if there are actually people who think dinossaurs are a conspiracy, a the Earth is flat.....
Please - explain how all life on earth is related to each other from a proteome / genomics perspective. I would also love an episode on Evolutionary developmental biology.
Hi. Could you do an episode on the different types of eyes in vertebrates and invertebrates, comparing all the differences and similarities, convergent evolution, advantages and disadvantages, etc? Thanks.
Cool my undergrad research project for my Geology degree was part of a study using E. notchpeakensis as the base for stage 10 of the Cambrian Period (though I was mostly finding trilobite species to strengthen the GSSP case for it)
Cool... I just got a little geologist tour of a great piece of strata in Gros Morne National Park in Newfoundland. Conodonts were key there. (the sequence there is a UN world heritage site)
I was re-watching the Eons about the Terror BIrds today and noticed the little time mistake re Pleistocene period at the end (already noted by viewer & acknowledged by Eons team), but it got me returning to my Chronostratigraphic Chart, which I am still trying hard to memorise. You say that these fossils are used as key period boundary marking index fossils, and I know other key stratigraphic indicators (KT boundary = ashy irridium layer) and the red oxide layers (banded iron formations) that indicate increasing oxygenation in sea converting iron to rust. Could we maybe have a 'Top Ten' index that quickly goes over the most important index strata that all newbie geologists should be able to recognise at a glance, in the field? The Eons 'A Brief HIstory of Geologic Time' runs through the periods but doesn't link them to them to rock strata, which is where they exist in the real world rather than in text books. Anyway, many thanks for another excellent Eons vid (am addicted) and best wishes to the Eons Team! fdb x
What a great idea! I too know some of the rock indicators but only a few and it would be awesome to have some sort of chart showing the most important time markers.
Love it! You did a great job of keeping me in suspense until the very end. This begs an idea for another video...which extinct creatures survived for the longest duration's before going extinct? Are the conodonts one of them?

I love when Kallie hosts an episode, she has such a passion for everything she talks about. Keep up the awesome work
She's cute too.
I find her voice quite soothing
But she has gauge in her ear
I hear from her voice how she's nerding out about the subjects of videos, which I really appreciate :)
I also feel this
I even skip those videos that she doesn't host

This is definitely my favorite new channel on UA-cam. And there's eons worth of subject matter.
Thirded. Motion carries. Eons is the best!
peter Carioscia, you got a real funny Joda picture.
from the scene on Dagobah where luke loses his concentration I guess?
peter Carioscia +++
A video on the evolution of trees? Or maybe the Entelodonts?
You means flowering and conifers?
Tyrannosaur Friday Play Love this suggestion.
Or the now invalid seed ferns which was thought to be a distinct group in between spore producing ferns and gymnosperms?
By all means. That would be great.
Like for example archaepteridiacea which is the closest I can spell which looks striking close to conifers.
Thank you for doing this! Yep. They are so distinct that geologists will often use them to define upper and lower geologic boundaries. Like you said, they make great index fossils.

I couldn't be happier that they turned out to be bug-eyed wigglies.
Um, not really bug eyed...
Insects have evolved a totally different type of eyes.
Bug-eyed is a figure of speech for oversized, staring eyeballs. People talk about 50s movie monsters as bug-eyed not because they had compound eyes but because they had oversized eyes.
I added a hyphen to make it clearer, since I believe it's usually written that way.

But they are the ones that petroleum geologists love.
Can you please do an episode on Brachiopods. I spent a whole semester in 3rd year at University speciating a box of them.
Sounds like a semester well-spent.

What a great idea! I too know some of the rock indicators but only a few and it would be awesome to have some sort of chart showing the most important time markers.
Awesome video can u guys do a like top 5 or 10 discoveries that changed they way we think of the past
Awesome videos like always 😁
Fascinating! Please keep up the informative content, I love it.
NEXT VIDEO IDEA!! Can you "see" viruses or bacteria from prehistoric eras? And if so, what are some interesting ones?
Love it! You did a great job of keeping me in suspense until the very end. This begs an idea for another video...which extinct creatures survived for the longest duration's before going extinct? Are the conodonts one of them?
That would probably depend on which taxonomic level you are looking at: species, genus, family, order?
I'd love a video about pharyngeal gill slits and the evolution of jaws! Not that it'll help me study for my paleontology/vertebrate zoology exam :)
what about:
soft tissue on dinosaurs and how far can speculation get
I love Eons. Thank you!
I was about to watch Planet Dinosaur on curiositystream, but couldn't find it and I found out it's not available in every country, mine included. You should probably give out a warning for something like this!
You guys should do an episode on isopods
This narrator is so much good than the previous one. He was always in a hurry.
Could you perhaps do a video in the future about the flying speed of small pterosaurs? I have tried looking up pterosaurs flying speeds, but the only information I could find was on larger pterosaurs like Quetzalcoatlus and Tapejara.
Great episode. (Nice timelines, too! =)
I'd like an episode about limestone and flint! Arguably two of the fossil products that were most crucial to the development of human technology, long before fossil fuels were.
Wow! Life on this planet is amazingly resilient!
As someone who works in mineral exploration/geology as soon as I saw the title I thought "That has to be conodonts!"
Fascinating! Excellent presentation.
glad I watched
Please make a video about significances of the teeth in paleontology or about evolution of teeth...
Love this channel!!
How about an episode about forams and information that we've gained from the stable isotopic analysis of their shells?
So cool! Thank you!
I want to see a video about ancient ants and bees. Where did the hive mind like this originate and what was it like back when it was starting
this is the most mind blowing thing ever
Yay! this was a very interesting video! thank you!
Do something about giant birds like argentavis, pelagornis etc
