Look....Another bug! Oh joy!
Bugs are good for you. They taste good, (so I've been told. It hasn't been my experience that they taste too good). ((yes...If you must know, I've eaten bugs. Insects and mealy worms. Ants and grubs. Crickets and grasshoppers. And *gag* a scorpion. Not because I wanted too, but because a large, burly survival instructor made us)). Bugs are chock full of protein and will keep you alive. They also contain water and can help to keep you hydrated.
I suppose if it comes down to life or death, I might eat another bug. But I won't eat a grub. Nope. They pop when you bite down. Goo squirts everywhere inside your mouth. And I'll never ever touch another scorpion, no matter how hungry I get. They have an external shell and it's tough to peel a scorpion. Plus....ew.....I am not afraid of much, but spiders and scorpions give me the willies.
Anyway, it's late so I need to get this post done. You see, Mother Nature decided tonight would be a good time to cause the power to go out. No....that's not fair. I can't blame Mother Nature. I don't know if it was actually her fault. All I know is, it started raining really hard as soon as I got home, and my power went out a short time later. In fact, I had just gotten my pictures taken when the lights went poof.
So I sat in the dark while it poured outside and read my kindle. I was considering going to bed when the power came back on. So after I restarted everything, I decided I'll do my post tonight instead of making a lame excuse tomorrow morning.
I couldn't pass up on Friday Rocks! It's my chance to show how eccentric I am because I collect rock with dead things in them.
The fossils I have for you today are my newest ones. Not in terms of age. They are new in the sense that they were just delivered today. I was actually only expecting one, but when I opened the package, there were two fossils in the box. (well...3 fossils and 1 ichnofossil, actually). I have purchased from this dealer before, and because of my return business, I got a bonus. And it's actually something cool. Something I didn't have yet, so....yay for me!
Anyway, that bug up there is....say it with me....a trilobite. It's a Flexicalymene. And it's actually a very nice example of a flexi. I do have several other examples of flexi's, some enrolled and some prone, like this one. So, why would I spend more money on a bug I already had in my collection? Well, lets flip the rock over, shall we?
See that peeking out there on the underside of the flexi? That is another trilobite. This one is an Isotelus maximus. This trilobite came from the Arnheim Formation in southern Ohio. And while both Flexicalymene and Isotelus are common for that formation, finding them together in association like this is quite rare. Especially considering they are both complete specimens. (the isotelus is enrolled so the picture doesn't show the cephalon, only the pygidium).
I do have another nice isotelus in my collection, and it's also enrolled, but it is quite a bit larger than this one. This one is actually a young one. We'll call it a toddler.
Now, remember how I said I was expecting the one, but I got two? What I've shown you is what I was expecting. I knew I was getting a flexicalymene with an associated isotelus. That's two, two, two fossils in one! But like I said, this dealer sent along a bonus fossil. A very nice fossil even. Here, I'll show you:
It's another enrolled Isotelus maximus. And it's actually in very good shape for the type. So what makes this isotelus so neat? Well, if you look at the top of the fossil, you see that cone shaped piece of concretion? That's not just an odd shaped rock. It's an Ichnofossil.
I have shown off ichnofossils before, but not in the Friday Rocks series, so allow me to explain.
Ichnofossils are also known as trace fossils. They are the fossilized remains, not of a living creature, but of the evidence they left behind. Foot prints, burrows, poop, etc. Remember the fossilized poop I showed off earlier? While it is called a coprolite, it is also an ichnofossil.
This ichnofossil is actually the remains of a cephalopod living chamber. It's not the actual remains of the chamber it's self, but a mold of the chamber. (I'm guessing it was an Orthoceras, or 'straight horned' nautiloid. I could be wrong though). What happened is, when the cephalopod died, it's body rested on the sea floor. The soft tissue rotted away, and the shell/horn filled with silt. Then the shell/horn decayed away leaving this cast of it's shape.
I do have an example of an orthoceras fossil. Many people who have bought a fossil at the museum gift shop have them. They are very common and usually they are polished. This is the only cast of an orthoceras I have. (if it is, in fact, an orthoceras. It could be some other nautiloid. But the orthoceras is of the right age and is also found in the Arnheim Formation where this was found, so.....it's a good supposition).
Anyway, before I go, here are the rest of the pictures I took of these fossils. I have to apologize for the pictures this week. Normally you can expand them to see more detail, but for some reason, (oh, I know the reason...it ws the power outage and loss of internet), they did not automatically upload to my Dropbox folder. So when power came back, I had to connect my phone directly, and for some reason, they imported as smaller pictures. I could probably get them to import at full size, but you know what? It's almost 9:30 and my alarm goes off at 4:30. Ok, sure, it's still 7 hours away, but I am an old otter and I need my sleep. I would say I need my beauty rest, but who would I be kidding; if I ain't beautiful after all the sleep I've gotten yet, I ain't gonna get beautiful. No, I just need my sleep because I'm old and I get crankier if I don't get enough sleep. So...good night, sleep tight, I hope the bed bugs bite you, because then they'll be too busy to bite me. Yes, I am that big of a prick that I would wish for you to suffer so I can get a decent night's sleep.
