a pair of unusual trilobites termed "sail-spined" by some due to the
dramatic row of axial spines found in this species. While some are larger, these
are in an excellent state of preservation, sure to become the cornerstone of any
trilobite collection. They are well matched in size, and the different poses
show off their spiny armament to good advantage. These spines were a good
defense against the fish of their day, affording quite a mouthful for any
predator with the temerity to attack

What level of mutation are they?

mutation? evolutionary example maybe.

the holy grail of trilobites.

I was wondering what level of evolution they became and if they continued to
something more modern or if they simple went extinct.

it's hard to say that they would have evolved a certain way w/o knowing their
mating habits, life span, environment changes, was food plentiful in their
environment, the list goes on and on. the only thing you can suppose about the
life and times of any extinct animals is what they were found with. you could
say that the spines wre for grown for defense or maybe as a show of manhood for
mating purposes. any more is just speculation.

So there isn't much to trilobyte geneology then. other than it's low aptitude
for negotiating a rock in its path or something perhaps with motivation?

My doctor put me on topical steroids for two months to get rid of these
fuckers.

Swimming at rooster rock can do that to a person, 90130

I wouldn't swim at Rooster Rock if my life depended on it, PLP.
Best be careful where you sit down out there. Bound to get a used hypodermic
needle stuck in your ass.

actually never been to RR, but I hear its absolutly terrible. Collins Beach is
pretty shady, I have witnessed.

That's pretty awesome. We found some of those in a quarry when I was a mere
lad. Back in Ohio I believe. Or maybe Georgia. Can't remember. My dad used
to drag me and my brothers to all those places when we were kids. It wasn't
till I was older that I really learned to appreciate it.
