Re: Bump for simple
simple was a complete waste of time and I for one am glad he/she is gone. I've had my fill of ignorant, egotistical, obnoxious jerks like that and don't intend to waste anymore time with them.
I'm with holmes. Newbie posters should be restricted to the Welcome and Free For All forums until they *prove* themselves. Right now there are a ton of posts left hanging because newbie drive-by posters think they know it all, post like mad for a few days, then disappear when they start getting burned or don't like what they're hearing.
Frustration on everyone else's part leads to degradation of the posts - although to be fair, I didn't think the posts in reply to simple were all that bad - subsequently, the threads disintegrate quickly.
Again, good riddance!

Gee... I wonder why
How about getting rid of the attitude?

Re: Actual Examples of Sorting?
There are examples of such a thing, but they are the result of various geologic processes such as thrust/reverse faulting, landslides, etc.
Hmmm... after re-reading this reply, I should have stated that I was referring to places where fossils are *out of order.*
I apparently didn't read lunkhead's post correctly, either. DUH!
Fossils from different time periods are not found in the same 'depositional stratum.' Meaning that you will never find Jurassic forams being deposited with forams only found in Tertiary rocks.
You might find them in the same vicinity, but they will be separated by either other strata or unconformities (e.g., erosional).

Excellent, Nosy! I'm keeping that link for future use.

Re: Actual Examples of Sorting?
Yes, Bill, I agree with Moose, your first message was good. I don't understand why you would delete it. I didn't read your second message, but it was a reply to mine.
I would have liked to have read it. I wonder if you had commented on my rather cryptic and ill-written reply to lunkhead.

Re: An apology - Re: Please delete
I did the same thing - misread Lunkhead's statements.
{Comments from minnemooseus/Adminnemooseus - At the time of the original version, I didn't give either the message or the context a close study. My hazy recollection of my then impression, was that Bill's message was a little off target, but still had significant good information. Perhaps a better "deletion" message would have been nice - Something like "Deleted pending rewrite".
Although not wrong in this topic, some of Bill's material might be better as part of a "Geologic Column" topic.}

In case of articulated skeletons, ichnofossils, and fragile fossils, this is true. However, in case of smaller shells, bones, teeth, and microfossils, this isn't true. Such fossils, like any sedimentary particle, can be eroded out of older rocks, transported, and redeposited in younger sediments, which can eventually become new sedimentary rocks, by a process called "reworking."
Yes, I thought about adding that, but sometimes I don't want to confuse people who don't have much geologic knowledge. Also, I guess I'm also waiting for people to ask questions before giving a more detailed answer. I've written long posts only to have them completely ignored or dismissed with a handwave before and I just don't feel like wasting anymore time with people who are uninterested in learning. I think I should probably not do that anymore, however.
I've seen reworking in action on the shores of Pyramid Lake, Nevada. Some beaches on the lake are white because they are composed of tiny gastropod shells being eroded [by wave action] out of localized fossiliferous outcrops. The fossils are not that old, probably several thousand years.
My problem is that I'm either too simplistic or get too complex in my explanations. I just can't seem to find that happy medium - especially if I'm rushed.
However, you always do a great job explaining geologic concepts.
