Only now found some time to finish this post...
My point is that acid soils will eat even teeth long before they can be buried in sediments (barring landsides). Is there some way I can make that clearer? Rapid burial is a requirement for fossilization. Gradual sedimentation doesn't cut it.
The top layer in forest is detrius, which decays to form acid soil.
Again:
Fossils are preserved in sediments, not soil.
LAL, please read again my post. It mentions how bones may survive and not be affected by the "acid soils".
Another variant you are not taking in to account is time.
Suppose just 0.05% of the bones of animals that die at a given forest are preserved each year. After say, 5000 years you may end with a lot of bones...
One extra factor: Ph is not the prime factor when it comes to preservation of organic matter. The key factor is the oxigen level. Reducing environments preserve organic matter while oxiding enviroments tend to destroy. Peat bogs are very acid environments, but still an excelent source of well-preserved specimens (soft tissues included).
BTW, on a slightly OT note, are you aware there are fossil soils? Including from forests? They are called paleosoils.
I will not bother pointing the mistake you made on the last line. I'll attribute it to an unhappy summarization.
Are there any late Pleistocene fossil beds with preserved remains of forest dwellers in any of the wet, mountainous regions of NA?

Not enought time to do any further filtering, there's lots of microfossils and marine creatures included, but at the very first page you will find papers on land-dwelling critters such as black bears and mountain goats.

Geology of the PNW, if you want to check the distribution of Pleistocene units.
By the way, bigfeet, if real, are scattered all over North America, so, restrict the discussion to PNW?
Now, we may argue on this forever, you providing reasons to explain why there are no known remains and I saying there could be remains. The truth, however, is the fossil records provides no backing for the claim bigfeet are real animals.
Remember:
Bigfeet- 2 to 3 m high, bipedal, looking like most common renderings of bigfeetand/or Patty and coehxisting with humans for some time in North America.
We are not talking about yowies, yetis, woodwoose, etc. We are discussing the North American giant bipedal ape.
Why have so many species left no fossil record at all? I hope you're not saying every animal that dies by a lake gets fossilized.
What I am saying is that its not impossible, there are known examples, primates included and acid soils have nothing to do with it. I can't see how one can interpret what I wrote as "saying every animal that dies by a lake gets fossilized"...
Its your link, LAL... Here it is again:
http://www.cartage.org.lb/en/themes...sAndFossilisation/Fossilation/Fossilation.htm (its the very link you posted a quote from).
And the part you seem to have missed is quoted below:
The best chances of preservation occur when an animal falls into a fissure or cave, is drowned and sinks to the bed of a lake, sinks into a swamp, is swept by a flood into a swamp or lake, is buried in a cool volcanic ash shower, or is overtaken by some other rapid process which preserves the body intact and buries it quickly. The great majority of hominid and early human remains have been found in cave deposits, river terrace deposits, lake beds and in down-faulted troughs (such as East
African Rift Valleys) which have been infilled by sediment and volcanic ash.
Is it so different from what I wrote?
The fossils were found in sand dunes, not lava tubes.
http://hvo.wr.usgs.gov/volcanowatch/2000/00_01_20.html
Read again, since you seem to have missed this part:
The discoveries didn't stop there. Archeologists found bird bones in limestone sinkholes at Barber's Point. Most importantly, ancient bird bones turned up in lava tubes on Maui and the Big Island.
It says fragmented bones were found, not fossilized bones. The rare find of fossils in igneous rocks were trees, evidently with high moisture content allowing their preservation.
You have at least a fragment of a bigfoot bone?
See what I wrote some lines above on our current discussion. I will as soon as I find some more extra time- propose an examination from a slightly different POV.
I've never agreed with you on that. They seem to be restricted to forests, usually in mountainous regions. Individuals sighted outside such an environment haven't been far from one.
LAL, please check the geographic distribution of sightings.
http://www.bfro.net/GDB/ will do (if you have something better online, please post a link); the sighting maps from Texas
http://www.texasbigfoot.com/habitat.html can also be used.
Thats not exactly "restricted"... Its a species that - if real - has a wide geographic span. Taking in to account the sightings distribution they are not restricted to mountainous and/or inaccessible areas. Unless not much can be draw from sighting reports, in other words, its unreliable or inconclusive evidence.
Yep. And the wronger you are, the more condescending you get.
So, are saying you are making a lot of mistakes?
I would say you make some mistakes, as anyone else.
