Pretty dull, these fossils, eh?
They look like keepers to me. Any trace of a life form that survives for so long is a marvel. Speaking of finding signs of see life far from water, my land is up on top of a big hill (nearly the highest point in the county). It was nice of the glaciers to deposit that kind of stuff here.

EricTheCat, I've got a fish too!
Cool. Once again I cannot see your image for some reason though.

The first one asked me to log into my goggle account...
The second one opened just fine - nice close up, nice fish.

So, I did mention that I had a few Trilobite pictures, here they are, both examples.
(I've had a hard time finding a good one at an acceptable price)

A little cluster of 'em
And my "best" one
Not a Trilobite but another fossil "find" of my own, a fern fossil;
Go backpacking in the right areas and you can discover things like this fern also — ya just gotta keep yer eyes open,

Rocks....rock. I love it every time a pet scientific theory goes to pieces due to some type of rock found where there shouldn't be any of that type. Sea creatures found at the top of Everest.

Maybe CSI can determine who it was from their teeth, but I'm pretty dense there in the forensics department. :D:D
If anyone has a clue as to what those last teeth are from — please enlighten me. I all know about them is that I sure wouldn't want their original owner chawin' on my arm.

Great stuff Bottom Feeder. I really like the trilobites. Also really like that fern that you found. That jaw section sure does look a lot like my ancient sheep piece. Any idea about where it was found? To tell you the truth I am no good at identifying this kind of stuff other than what is common around here.

They're not that scarce...
:D

Yeah, the trilobite is "ok" (thanks, BTW) but still not good as what I want. Now that I'm retired and can indulge myself a little I think I might start up the quest again. There's good ones, ya just gotta give it up for 'em.

Like all good technicians, I throw away the instructions first (or second) thing. So when I buy things, usually they come with a little explanation tag of some sort or another. Just another variation on instructions — if ya catch my drift.

The fern was (like most of my finds) an accident. In the 80s a lady friend and I were up backpacking behind Snoqualmie Ski area (in August), an introduction to backpacking for her. We stopped on a corner of the old road I was using for a trail and she sit her pack down on a small shale landslide of them. All sizes, it was just roadside shale (road was overgrown, hadn't been used in years). She got all excited about it but I wasn't about to carry around a couple extra pounds of rocks. She loaded up (and discarded most of them as we went along) and I picked up two; this one being one, the other broke in my pack and I threw it away.

I gettin too old, I got too much shit already.
:D:p:D

lol, I hear you. One thing I have learned about life is things accumulate. I am also not very good at keeping the slip of paper with detail. Yet somehow I end up with piles of paper that I will probably never look at. With electronics I tend to void warranties within a few days so at least I don't need to keep track of those papers.

Here are some fossil rocks from an area you are not allowed to collect. So I collected a couple pics instead, back when I still used film.

Oh, yeah, that too, I forgot about that. Gotta see how it works; how it went together; whats inside; can I monkey with it a bit...
:D
Darn right! Open it up, see what's really in there, maybe add a jack that didn't use to exist and wire it in, maybe pull a diode or two so the radio can transmit on other frequencies. Fun stuff. :delivery: -<(It's here, let's mod it!)

BONES

The problem with fossilized bones is that the good examples are just too damn big. You need a display cabinet that you can comfortably house your collection in, and that also will have to be large. And who wants a three foot bone in their living room for a coffee table. Although I sure some of the boys over in the Working Man's thread could turn one out that would look just primo. :D:D

dem bones....
We'll start with the school of fish bones:
and a couple vertebrae
another one

A chunk of arm bone, leg bone, whatever:
A small collection of bones

The last of my collection that I am going to post is not about rock, but fossilized stuff anyhow, fossilized pitch, commonly known as Amber.

Here is the first Amber piece I ever purchased. Comparatively expensive (back in the 80s it seemed to be more rare), and not very clear but it is still the largest piece I own.


The following pieces are much more clear with numerous bugs enfolded within their embrace

Sometimes, when you're handling rocks you have a clumsy episode; you move the mineral across the marble table and leave a deep scratch in it (did that), you pick one up a little carelessly and a crystal pops off (happens all too often) you click them together and one or the other suffers some degradation. Or, you drop one and it shatters. Which brings me to the point of this paragraph; as I was doing this photo shoot I dropped one of my four pieces of amber on the hardwood floor and I now have several more pieces of amber in my collection :mad:


Well, that's it, kids, all done with rocks. Hope y'all enjoyed it, I had fun. Now as long as Scorp don't get all upset by the ½ gig of pictures I put up on the server. :p:p:p

Dang! Never fun to damage stuff. More than one time when polishing a stone I have had the polishing wheel rip the stone out of my hand to go flying at great speed. Luckily nothing too bad came of it accept that I have to go back to the stage 1 grind to erase the damage on the stone basically starting over. One time I was photographing the progress of rocks I was tumbling. I adjusted the tripod and my main DLSR at the time (Canon 20D), slowly toppled over and nailed my cement basement floor as I watched. Apparently I did not balance it properly. From that day, it works fine normally but if using the AC adapter instead of a battery (generally for astrophotography) I need to wrap a rubber band with another thing to hold a part to make it work.

Well, that's it, kids, all done with rocks. Hope y'all enjoyed it, I had fun. Now as long as Scorp don't get all upset by the ½ gig of pictures I put up on the server.
lol. Yeah I try to keep the file size under control but certainly it adds up. Gotta hand it to Scorpio for running a forum that allows so many images and even large images. Once in a while it occurs to me that if all information was suddenly lost it would make a huge difference if what is in this forum somehow remained.

Hopefully once the snow melts I can come in with some new finds. It is always interesting to knock on people's doors and ask them if I can walk their land and look for rocks and stuff. ;)

Remember I said fossilized shark's teeth were fairly common? Well, ones this big aren't common at all:

Shark Tooth.jpg

Heh — puts my little 40mm teeth to shame.

I know, when I started this tread I asked that everyone post their own stuff and not just something they found on the internet. So here I am, breakin my own rule and postin that shark tooth. Ya know this ain't mine.

I wouldn't want to run into that shark!
Here's a couple of photos of one of my meteorites, a thin section imaged in regular white light and then with crossed polarizers. I have a really cheap setup and so the pictures aren't the best. The color changes in the polarized light image indicate crystallinity or composition differences, basically the way light interacts with the minerals.

How thin are those slices, lumpy? Are they about 1 sheet of paper thick or 10 sheets thick or so?

Wow that is nice. The shark must have been huge.

Very cool meteorite slice, lumpOgold. Thanks for sharing. I have wanted a set of polarizing filters to do that sort of thing for a long time, just haven't gotten around to it yet.

Hi BF, the thin section is polished to be about 1 micron thick, it is mostly transparent to the eye, at least all the feldspathic minerals are clear at that thickness. If I recall correctly, paper is about 50 microns thick (0.002").

Oh no, Eric don't need another hobby.

:D

(these new icons suck BTW)

BF
lol, no you just have to think about it the right way. It would be just a minor addition to my photography hobby. Yeah that's it. ;) I am one of those guys who if I retire early I will have no problem filling the time.

Dang, was it last weekend I was going to try and get some new rock pics? I don't know what happened to that weekend but maybe this one will pan out.

All the rocks and minerals I have were found by me so they are not great specimens like those shown here. I do have a couple boxes from museums with samples glued to a board and one has a solid silver nugget and a gold nugget in it. Those were given to me by my grandfather in the 80's.

Say zilla, shoot a few photos and lets have a look at 'em. None of our rocks are as pretty as pile of GAEs anyhow...
