Trilobites: the creature that looked on the world through STONE eyes!

There arnt many fossils of eyes, for the simple reason eyes are soft tissue, and that rarely fossilises. Interestingly though the trilobites eyes were made of stone, calcite to be exact, so there are many examples of fossilised trilobite eyes. You can get a trilobite fossil with amazing eye detail on ebay for about 50USD. From looking around, the trilobites from Morocco seemed the best to me. It was long thought that the calcite eye disappeared with the trilobites until it was recently discovered that brittle stars have many calcite 'eyes' all over their exoskeleton. Although it should be said theses 'eyes' are tiny!

Now I’ve got this image in my head of tiny alien paleontologists reconstructing Thunderf00t from his fossilized remains for Holocene Park Park. Of course there will be a tiny alien Jeff Goldbloom warning against the folly of such an endeavor. Inevitably, Thunderf00t breaks free and rampages all over the place, debunking everything in sight like a boss...

As much as i enjoy hearing you spout about solar roadways and various other sociopolotical events, pure learning on your channel is one of the best feelings on this website. Thank you Thunderf00t for being so educational and so fun for all these years, and many more to come (hopefully).

Those trilobites have no sense of humour, just look at their stony faces.

[BIIGtony]

No endless repetition, no reuse of clips for the 100th time, no beating of a super dead horse and in addition to that an interesting topic. Probably the best video you made in month.

Fascinating stuff. Also thunderfoot. This style of video is so much more enjoyable than a lot of the recent videos ive watched from your channel. The ones where you endlessly repeat the same points. Those videos get exhausting really quickly. It would be nice to see more videos like this one.

I'm kinda happy Thunderf00t is doing what he is best at again. I didn't see any of his videos for a while but this got me watching Thunderf00t again. Good job mate!

I wonder if they would be immune to medusa.

Hey Thuderf00t. I'm a recent fan of your channel. I know a lot of people suggest you themes, but I also want to suggest one: cape town water crisis. I think it would be cool because it looks like it will be the first time we will see a city suffering badly and in long term from the global warming (other than natural disasters such as hurricanes, etc).

Thank you for your time and keep up the good work!

[elliebennett]

Love the science stuff probably more than your other content, I'm glad you mix it up though :)

[elephantsintheforest]

Great video, I've always been mildly curious about trilobite eyes and you're the first person to bother explaining it in any great detail

[neilhoganwa]

I see people with stoned eyes all the time..

[haldon]

I love trilobites, and it's always exciting to see them featured in a channel. Thanks for making my Friday!

[Not-pnct]

How much for a fossilized thrunderfoot?

[CitricAcid]

This was extremely fascinating. I never knew the details of what made their eyes particularly special in the evolutionary context till now. Thank you.

Don't mean to be a hater or anything, but this type of video is much more engaging and interesting than your typical bash some stupid company videos. I mean, someone's gotta do it, but seeing real science is better, in my opinion, than seeing fake science. Keep up the good videos though!

[TheSaxaMEN]

Love your channel. And I couldn't find anything like it in YouTube. You are the best, man.
Keep it going!

What's the convertion rate of trilobite to megabit?

[tycho]

Also, this video was pretty damn interesting. Great job, Thunderf00t. We always appreciate you! :D

and if you buy another seven you'll have a trilobyte.
