5/13/19 Oglesby, IL Roadcut- Pennsylvanian shark bits, brachiopods and more

Recommended Posts

And now onto some fish/shark material. Most of what I found is only showing a little bit, so more prep will be needed to determine what exactly it is, or if it is anything more than just scrappy bits. For instance, each of the rocks in this pic show a little spot of black- there is some kind of fish material there.

The next one is also heavily obscured. There may be a lot more there. 5ce2fabf627c5_2019-05-1920_21_33.thumb.jpg.8ff6f3800712f7681d66021728370884.jpg

Sounds like a good site to go to.

Good luck with the hidden bits You found. Looking forward to seeing them prepped.

Great finds and trip report, hopefully one of us will find a complete shark tooth.

You're welcome, I'm glad I could finally get a report up. I've gone fossil hunting about 6 times this spring so far and had only posted the first one.

Thanks! Yard work has first priority for now, but hopefully I will be able to do some prep on these before too long.

Thank you! I like them too, I was so happy to discover shark teeth could be found right here in Illinois.

Thanks! With any luck the proposed fossil park will happen and we can look forward to an actual increase in fossil collecting sites for once.

I do like those brachiopods... of course I'm sure it's a rush to find those shark teeth and all, too. You didn't mention the partially covered brach on that piece with the possible Pinna, but it looks like a good one. Will you be prepping i out?

I will definitely try to prep a little more in between the two shells, since it seems both might have more to be exposed.

Thanks! I hope with some washing and cleaning up the crystals will look even better.

I had some time to do a little prep last night, so here is the Peripristis mostly cleaned:

After some prep I seem to have uncovered the extent of this piece. This seems to be a non-descript piece of fish bone or perhaps part of a tooth root?

This next one turned out very nicely- it's a small shark spine.

This little piece of something was on the same rock as the spine above- it's much too small for me to be able to make out any identifying features, unfortunately.

Finally, I have mostly prepped this piece out- I stopped because small bits were coming off. I would have to consolidate it before going any further and all I have for that is cyanoacrylate. I'm honestly not really sure what it is- it does not have the enamel shine of shark teeth, with most of it looking more like a tooth root. That plus the multiple small cusps/teeth on top make me think it's actually part of a fish jaw, perhaps? I would love to hear the opinions of some folks who have more experience with Carboniferous fish. @Archie @fossilized6s @TNCollector @RCFossils @Elasmohunter

@Fossildude19 helpfully suggested in an ID thread that my last piece may be a fish premaxilla, which got me thinking about another one of my finds, the bit associated with the brachiopod shell in my 5th post above. Looking at it in a new light, I am now thinking it is actually a scale, not a tooth. I tried to take a closer pic, but my phone is limited in resolution unfortunately. Here are couple shots in different light:

Sorry for the late reply not been able to get on for a while, great finds! This is a really nice example of a Petalorynchid type Petalodont tooth in lingual view, you can see the imbricated basal ridge at the bottom and there's probably be a nice root/tooth base underneath still hidden in the matrix. Coincidentally I prepped one very similar to this last week from a similar aged marine deposit, its in labial view. I couldn't find the root so this is just the crown with the basal ridge (slightly damaged) at the bottom. Your multi-cusped object is definitely a shark tooth too , reminds me very much of the Pristodonts. That spine is really awesome!! :envy:
