The Most Successful Lineage to Go Extinct? | Lindsay Nikole

Lindsay Nikole | August 23, 2026



Before the dinosaurs, before trees, before jaws even existed trilobites were already thriving in Earth’s oceans. This video uncovers their bizarre adaptations, ancient conga lines, rock-made eyes, and how they outlived not one but two of history’s worst mass extinctions.

    11:03 holy moly an American that says “ET cetera” correctly instead of the whole cloth made up “eck cetera” whatever the fuck that’s supposed to mean..🫪I mean I know what it’s supposed to mean but..whatever you get my point! The point being that saying “eck cetera” is fucking stupid.

    Anyhoo

    As a Cajun, I see trilobites as a missed culinary opportunity. I bet they tasted like shrimp but I'll never know, sadly. If trilobites were alive today, you bet there'd be a whole Cajun seafood industry built around them. Already on the half-shell, not needing to be cracked open like oysters. No more meat on them than crawfish but available in equal quantity, and so we'd have huge, communal trilobite boils right beside huge, communal crawfish, crab, and shrimp boils. Aquatic arthropods (and really, most arthropods) are quite tasty, at least if seasoned properly. Few arthropods taste good raw or unseasoned. But I eat the Hell outta arthorpods and so I see trilobites as food, and am sorry I missed getting to taste them.

    I love how you make your videos! Would be extremely interested if you do a longform on how you set up and edit your videos!

    Also :P, plant fox here. Look into the complexity and diversity of lichens and mosses.

    2:55 Cicada molting!

    A couple of weeks ago I was visiting the grave of a fellow Magic the Gathering player, and there was a cicada's shed decision his headstone.

    So I left it there, but went around to all of the nearby trees looking for more castings. Not only did I find dozens of them, I found one cicada in the middle of molting. I initially thought it had died in the process, but no, it was just taking its time. It's wings had fully inflated before I left, but they were still all shriveled when I had first found it.

    I've gone back to the cemetery a couple of times and found more molts, and I found another one that had climbed a tree, but hadn't shed yet. I gave it some space while I looked for more, but it vanished. It wasn't on the ground, and it wasn't on the tree. I'm guessing it got eaten by a bird.

    Btw, I used a deck box to gather them. 🙂

    So many fossils and survived so long. I still find the idea of no trilobites almost unbelievable. The oceans are so big and deep the idea that they're all gone is just mind boggling🤯

    I think you should invest in an overhead projector, the clear film sheet light projector. You could project onto the wall and have a "whiteboard" too.
    We had one in elementary school, and it was really cool and made it easy to do lessons.

    Come for the freaky body plan, stay for the freaky nomenclature, Schmidtiellus reetae! I dont know if there is a name I can now like more than this one for being so funny/terrible (sounding)!

    I tried to give my cat his wet food as breakfast. This asshole decided he would power run up the stairs and slam his body on the door at 6am every morning he chose not to be in the room with us. Now he has to wait until 8:30pm, after his auto feeder breakfast and lunch.

    If we include "minor" mass extinctions, it took 5 to finally kill off the trilobites. Whether by the fury of a pissed off god or by the machinations of Nature, you gotta admit these dudes absolutely did not bend to anyone's will. Stuff got thrown at them, and they kept coming back, flipping off the Universe in defiance as everything else died around them.

    Also, notice that the dinosaurs only appeared in the fossil record after the extinction of the trilobites. Obviously, this is because that is what it took to make the conditions for dinosaurs to feel safe enough to evolve.

    Reminded be of a fun somewhat mind-blowing thought; LUCA is alive today, the individual organism, literially (and if it turns out life only evolved once, then that specific individual living thing is also still alive).
    Since any lineage that has only ever reproduced by mitosis* has only forked, not reproduced and died – one living cell becomes two, but both are still the original individual, and that never stops being true.
    *things like sexual reproduction are a bit fuzzier in terms of what counts as the uninterrupted continuity of an individual living organism, arguments could be made either way.
