In a quest that has taken him from Oklahoma to Morocco and Poland, Brett has analyzed multiple examples of mass trilobite burial. A smothering death by tons of hurricane-generated storm sediment was so rapid that the trilobites are preserved in life position. These geologic "snapshots" record behavior in much the way that ancient Roman life was recorded at Pompeii by volcanic ash.
Burial was rapid, Brett said, but also somewhat delicate. Trilobites, like other arthropods, shed their hard exoskeletons from time to time.
"We find molted pieces lying immediately adjacent to each other," he said. "This is proof that the sediments were not significantly disturbed after burial."
Like modern crabs and lobsters, trilobites appear to have gathered in large groups for protection when they shed their protective exoskeletons. During molting, there was safety in numbers. And, like their modern cousins, trilobites seem to have used these molting gatherings as opportunities for mating.
The mass burials preserve large groups of similar-sized -- and therefore similarly aged -- specimens, segregated by species and, after molting, "naked."
"It's an orgy," Brett said.
Brett and colleagues found evidence of another behavioral connection to modern arthropods -- long chains of trilobites apparently fossilized in mid-migration.

Except one problem....... no people in the Devonian age
Okay, people.
Knowing trilobite mating habits like I do, they have to shed the exoskeleton to mate.
Like many other species they find a nice warm backwater enmasse.
After mating the males die and drift away.
The females bury themselves in the mud to gestate.
When the eggs hatch the females die and are entombed in a mass grave.
Can I get that grant NOW?
Well, not everyone's Charlie Sheen, you know.
He’s only a shell of a man.
Discarded and adrift....
Trilobite orgy.
Well... check off another couple of words I never would have thought to see together in a sentence.
“Someone — shut that door.”
Trilobite, the other, other, other white meat.
He’d probably be a decent human being if he’d come out of his shell.
Charlie Sheen sez these trilobites died of some cause that the gov’t is trying to keep secret.
Maybe that’s just the proper name for a group of Trilobites, “an orgy of trilobites”, analogoust to “a murder of crows”.
I’m not gonna ask how you know this.
The same way they know this.
A smothering death by tons of hurricane-generated storm sediment was so rapid that the trilobites are preserved in life position.
I F***ING MADE IT UP.
teehee
Not to be confused with Troglodyte mass matings.
You are assuming that the alleged “geologic ages” actually reflect reality. Lot’s of assumptions for that to be the case. And there is plenty of evidence to dispute it.
This appears to be an error, although the exact placement of the Trilobites within the Arthropod id not certain. It appears that trilobites are no closer to crustaceans than they are to spiders and insects. Trilobites were an independent subclass of Arthropoda, and are totally extinct.
;’) She was a big trilobite, her name was Bertha.
HA Ha.....good one
NO more calls, please.
We have a WINNER!
That's right! Or "a slime of lawyers."
Cheers!
