Trilobites: Why?

Why should a ubiquitous scavenger that dwelt (dwells????) on the ocean's floor become extinct?

Makes no sense. Why? Could it be that they are still alive, scavenging? Who would keep such a thing secret? Why? But if they are, indeed, extinct, how did it happen? It seems that if everything all around you is dieing, being a scavenger is a good strategy.

Trilobites disappeared in the mass extinction at the end of the Permian about 252 million years ago. The trilobites were among the most successful of all early animals, roaming the oceans for over 270 million years.[6]


Don't buy it, not for a second.

entering a drawn-out decline in the Devonian culminating in final extinction of the last few survivors at the end of the Permian period.[17]

Bullshit.

Honk if you want the truth!!! :x :x :x

They were just too yummy, so they all ended up in some vertebrate's tummy. :Hungry2:

This one does.

It took us the better part of the Paleozoic era to evolve tummies, just so we could partake.

Not quite the real thing, but it will have to do:

Their inability to adapt to changing environmental conditions. That's the ticket.

And Trump. I blame Trump.

Adapt. In a Darwinian sense.

Something happened in the environment and they were no longer able to scavenge. They died. Became extinct. They snuffed it. Joined the choir ... and so on.

Am I a fag? No. Not that there is anything... wrong... etc.

But if you're really... curious, suggest you ask AA. In a PM of course! :)

The evidences am that there is catagorically NO reason for them to have become extinct.

Remember absence of evidences am not evidences of absence

Trilobite cryptids hidden in some dark moist corner of the world?

The NYC sewer system perhaps? Maybe at one time but the giant albino alligators got them.

History repeats itself, sorta. :lmao:

I hereby vow that I will devote the remainder of my life to uncovering the sordid truth behind the Trilobite Conspiracy.

They didn't die off, that is a scurrilous lie. I call on all of you here to join me in my, nay OUR effort to discover the truth!!!!

ed, are you into evolution conspiracy theories now? There's a very simple reason trilobites went extinct: they evolved eyes, got a good look at each other, saw that they were totally fucking ugly, wouldn't do each other anymore, and died.
"It is not I who is mad! It is I who is crazy!" -- Ren Hoek

"[... it seems most strange that... ] the Creator of Heaven and Earth resorted to the womb of a certain Jewish lady, grew there for nine months and was born as an infant, and afterwards grew up and was betrayed into the hands of his enemies who sentenced him to death and executed him, and that afterwards... he came to life and returned to his original place. The mind of a Jew, or any other person, simply cannot tolerate these assertions. If you have listened all your life to the priests who have filled your brain and the marrow of your bones with this doctrine, and it has settled into you because of that accustomed habit. [I would argue that if you were hearing these ideas for the first time, now, as a grown adult], you would never have accepted them." -- Rabbi Moses ben Nahman, defending the Talmud at the Disputation of Barcelona, July 1263.

"God is the supreme excuse for human adults to absolve themselves of any obligation to preserve natural resources for their own children during their lifetime." -- Gene Ray

I'd love to see a real true-o living trilobite!

They had even more variety than you suggest (quoting from Wikipedia).
Trilobites had many lifestyles; some moved over the sea bed as predators, scavengers, or filter feeders, and some swam, feeding on plankton. Most lifestyles expected of modern marine arthropods are seen in trilobites, with the possible exception of parasitism (where scientific debate continues). Some trilobites (particularly the family Olenidae) are even thought to have evolved a symbiotic relationship with sulfur-eating bacteria from which they derived food.

And yet, after 250+ Myears the Permian extinction got them. Apparently… ( :mrgreen: ) But that was after a long, slow, decline.

Another weirdness (still Wiki):
By the time trilobites first appeared in the fossil record, they were already highly diversified and geographically dispersed.


Some pics just for the fun (be aware that most trilobite fossils are in fact exoskeletons shed during molt):

Did they taste like lobster?

Everybody loves lobster, right? Not me. I think it is like eating a big spider.

A long time ago in sea far, far away we had lobster for the first time ever. Luxury! proclaimed most on that day; day one. On day two we had the same. Three though twenty, the same.
Apparently our chief steward got a great deal on lobster at some god-awful port.
I suspect money traded hands in the opposite direction.
I also suspect it forever ruined it for all .

We'll have to wait till ed locates one. Then we can taste it – and donate the pathetic remains to some museum, just to mock them. :twisted:

It was God's punishment for all that trilobite sinfulness. :)
