Is...is that Quisp?* Where did you find Quisp? That’s Quisp, isn’t it? Man...you have to hook a man up with some Quisp! I need some Quisp! QUISP! Give me all that Quisp! I will give you monies for Quisp! Or I will beat you senseless and just take all your Quisp. I am a man who needs Quisp, and you must not deny me! Please? Can I have some Quisp?

Sadly, that’s actually the way I feel. Those of you who remember Quisp will understand. Those who don’t know what it is, well....I pity you your empty, pathetic life.

But, alas and alack, I must needs move on with mine scrivenings, ere the foulest beast known as Distraction should waylay me. Verily, forasmuch as the palsied beast of eld cankers my poor limbs, it is with haste that I must needs progress to the main import on this days delving into the world of the odd.

Read that last paragraph in your mind using Sir Patrick Stewarts voice. You’re welcome.

Today is the day known as Friday Rocks! It’s the day when I indulge my hobby, and fascination with, fossils. That is, rocks with dead things in them. So, let’s get started, shall we?

Take a close look at that rock pictured up there. What the heck is that, huh? Well, it’s not Quisp, I can tell you that. (disappointed Otter is disappointed). And the funny thing is, I’m actually messing with you! Because it’s not a fossil! HAH!

Seriously....it’s not a fossil. Every now and then I find a rock that isn’t full of dead things that catches my eye. And this is one of them. One of the reasons I like it is, well....it kind of looks like it could be a fossil, doesn’t it? It almost looks like a cluster of shellfish. But it’s not. It’s actually a concretion of Siderite. And what the hell is Siderite? It’s iron carbonate. (FeCO3)

And iron carbonate is one of the most valuable examples of iron ore out there. Unlike most iron ores, it doesn’t contain any sulfur or phosphorous. That makes it much easier, and safer, to refine. In total, this Siderite is 48% iron.

Now, I know what you’re thinking. “Otter....there has to be more than just some iron ore on this rock to make you want to take away precious display space from your fossils”. And, yup. There is. When I display it, I have the Siderite showing, just like in the top picture. However, if we turn it over......

Oooohhhhhh.......purtty.....

So, what are you looking at? Why, my thumb, of course. And the rock? This picture does not do it justice. All that stuff you see is small cubes of iron pyrite. Yup, the backside of the Siderite is covered in fools gold. I tried to have the pyrite cubes catch the sun and be all sparkly, but as you can tell, I’m not a very good photographer. I’d blame the camera, but it’s an iPhone 6, and that camera is decent, so it must be me.

But anyway, even though it’s not a fossil, I still wanted to share it because it is something cool to look at. And no, I’m not going to deny you a fossil today.

When I first started doing my fossil posts, I described some of the different types of fossils. This is an excellent example of mold fossil. What you’re looking at is a crinoid stem, (columnal), with the body missing. When this crinoid died, it’s internal structure decomposed faster than the outer shell. Sediment seeped in and filled the void. After it solidified, the rest of the crinoid decomposed and nothing replaced it. This is called Authigenic Preservation.

This example shows two views of the same crinoid. The long one is a side view. It reveals 11 segments of the original animal. the circular view is a top down, (or bottom up), view of one of the segments.

This picture is of a stunning waxing gibbous moon....I mean, uh....I took this one to show the level of detail you can see in the segment that was preserved. Finer sediment allowed for more of the fine details to show up.

And, well....I guess that’s it for todays post. I would wax poetic about crinoids more, but....I’m still in the collecting phase of ‘Ohh...neat-o! Otter want’s!’ when it comes to crinoids. I am starting to pay more attention to the Echinoderms, (crinoids, starfish, sea urchins), so I am teaching myself about them, but my knowledge level isn’t up there yet. At least, it’s not up to par with my trilobite knowledge. But I’ll get there. And as I learn neat stuff, I’ll share it. I still have more crinoids to share, So I’ll be sharing more, interesting, things about them in the future. But next week, I think I might go back to trilobites. Unless I do a post on teeth. I have teeth, too. Shark, dinosaur, heck, I have a really nice example of a Megalodon tooth. It came from a small one, though. Only about 50 feet long. But, I’m getting ahead of myself. That’s a story for another day.

Have a great weekend, and I’ll be back Monday with the truth or a lie.

* Quisp was a cereal I enjoyed back in the 1970’s. It always had the best toys. And it was tasty, too. Kind of like Cap’n Crunch, except softer so it didn’t slice up your mouth. You can buy it online, or in stores in certain areas of the US. But sadly, not where I live. And, to be honest, I’ll buy a lot of things online, but cereal isn’t one of them.
