    For decades, one of the most abundant kinds of fossils on Earth, numbering in the millions of specimens, was a mystery to paleontologists. But geologists discovered that these mysterious fossils could basically be used to tell time in the deep past.

    Weird, I didn't realize it was the same person. That museum of the rockies video felt like the hostest was taking the viewer or inventory person out on a date. I prefer this format. Much more toned down and less sickening. And it's focused on why I came here in the first place. Much appreciated.

    Thanks for this highlight!! My PhD work involves the study of chemical signals preserved in conodont apatite, so essentially all I do is pick them out under a microscope so I can dissolve them for mass spectrometry (sorry biostratigraphers :)). They are truly a versatile thing (similar to diatoms and forams as others have mentioned). Great job!

    So they got extinct by high Carbondioxide level in the atmosphere.
    We use their remains to find gas and oil.
    Which we use to increase the Carbondioxide level in the atmosphere .
    I wonder for what our remains will be used in the far future.

    It's very interesting that they were so common and they are almost completely absent from reconstructions of sea life from periods they existed in.

    • Dragrath1

      Small ubiquitous creatures are to this day under represented as well sadly so a big part of this is probably a bias towards colorful showy or impressive creatures

    • Indigo Rodent
      Indigo Rodent Hace 2 meses +1

      It regularly happens with modern paleoart too, though. Conodonts are very rare despite that they were supposed to be so common.
      Though I guess the species composition in it can be some sort of an artist meme that endures from the past .

    • Dragrath1

    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.

    Dear Eons folks, first of all I'd like to say that I love your videos! But sorry :( I have some critics to this one, which is also awesome, apart from a few misleading informations. (1) why did you chose the conodonts among the very large number of microfossils group as the most important ones? Microfossils in general are very useful for biostratigraphy (telling time), in paleoclimatic, paleoenvironmental, paleoceanographic reconstructions... (2) why do you separate paleontologists and geologists in 2 distinct classes? Independent on what the paleontologist studied in his undergrad studies (biology, geology, history...), the guys who work or worked on the biostratigraphy of conodonts (and any other group) are virtually the same guys that discuss their evolutionary relationships. These are really not two different groups of scientist...

    I understand that educators need to dumb down science to make it understandable, but it leaves out so much information, that some people get the impression that it must be all guesswork because they can't understand how the science got to their conclusions. Take the aging of things with what they find in the layers: "How can they say for certain?" since the earth is not a controlled environment for experimenting, nobody was around to document what things were like, making things seem like it's all guesswork. The scientific method says there must be repeatable results, but that would take 4.8 billion years according to science. Leaving the debate open for creationists to say the earth is only hundreds of thousands of years old because they too don't have to repeat their claims.
    Is science just a belief system when it comes to aging, or is there information that is missing & would solidify their claims without repeating results?
