    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.

    Perhaps they werent as abundant as they seem cos they lingered mainly around dead bodies eating dead matter which later became fossils. Hence they cld get wiped out despite turning up all over the fossil record.

    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.

      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 11 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

      Probably an artifact of the ignorance of Paleo-Artists at the time of production. It doesn't help that for a long while we had no idea what creature they came from
