Large ordovician tooth?

Recommended Posts

Jasper_M

First off, I don't know anything about paleontology. I found this fossil in Nicholas county Kentucky. It was about at the C in NiCholas county on the map. Sorry it's upside down, but Nicholas is 2 above bracken, assuming picture orientation. The fossil was 6-10 feet down. The first layer of fossils went down about 5 feet, maybe more, and we're tan and sandy. Below this layer was a gray layer, and this was several feet into that. Also, don't have enough file space to do enough pictures for inches, but it is about 11.5 centimeters long, or 4.53 inches.img_20190705_2037009_OufC3.thumb.jpg.e8ada9fa86dccf81759e9b7c9d4bc6bc.jpgIMG_20190705_204613524.thumb.jpg.d2f83819e9c260ebea872684d696bcf8.jpg

There we go. It is okay to post more pictures as a reply right?IMG_20190705_204547230.thumb.jpg.b21ebee2071f040b16a79a060ba5f408.jpg

No idea what it is, but the pyritization is nifty.  However, if it's Ordovician, it won't be a tooth, as teeth hadn't evolved yet.

That's confusing. The darker orange is listed in the Kentucky almanac as upper ordovician, and the light as middle.IMG_20190705_203741134.thumb.jpg.be5edecee5cfd3a4f3bcc7edc80a2dfd.jpg

I wasn't sure it was a tooth, but I don't know what else it would be, although I wouldn't know anyways. My Grandpa said teeth were very rare to find, but occasionally are found in the area. No credentials though.

Another angle. IMG_20190705_202929059.thumb.jpg.0e2e5a4d0b97d6703f84834a1dd36446.jpg

I think it may be a bryozoan encrusting on something. The something could be a horn coral based on the cone like shape but it is pretty hard to tell from the pictures and the fact that it is still embedded in rock and maybe a bit worn. Let’s see if anyone else can see something different.

Sorry, but I doubt it is a fossil, or at least that it's identifiable as such.

What is a bryozoan?

It is in an area with many other fossils, and nearby rocks showed trails in them, possibly from small creatures. Not a fossil as in it wasn't organic?

I see nothing to indicate that it is organic. Slightly different concept, but it isn't a fossil until evidence says it's a fossil.

It’s definitely not a tooth as hemipristis said. If it’s not something geological, and is a fossil, then it’s likely some form of sea life as fossils of coral, bryozoa, etc. are abundant here in Kentucky Ordovician rock. It’s hard to tell though exactly what it may be. Having it in hand may be the only way to tell for sure.

 

Honestly, this in your picture looks to be more identifiable as a fossil. Although it is still hard to tell what it is from the pictures. It could be a piece of a brachiopod/bivalve or maybe a piece of rugose horn coral. I’m thinking it looks more shell like, but septal grooves on horn coral can show up like that too. Especially when wet, which this appears to be.

Is that what we are supposed to be identifying ? :unsure: 

If so put me down for never mind.

 I don’t think it’s what the OP was wanting identified, but out of everything in the pic it’s what stands out the most as a fossil to me. Just wanted to point it out, in case the OP overlooked it. ;)

There's nothing embarrassing about asking questions that help you learn. Not asking the question and learning nothing from your experience would be embarrassing! Believe me, the rest of us on here are still learning too. I've stuck my foot in my mouth so many times already and I've only been here two months. Shake it off and move on.

 

It does look a bit like broken carapace, eh???

I thought I posted something new. Am I not seeing it, or did I forget?

I don't see it, so I'm going to assume I forgot to post. Some small details. The rock as a whole has three layers. The first is basically mud. It is a smooth light gray. Below this is a thin dark sheet that appears to cover everything, but is most prevalent on the specimen. Below this is the actual rock, or fossil. There is a light gray patch on the specimen where the darker layer is chipped away. Through this rock is visible. It has minute shell fragments, so it may be filled in. In this picture it is dry.IMG_20190706_191618947.thumb.jpg.510fc2a6027c99586d3832b2b8b497da.jpgIMG_20190706_191637984.thumb.jpg.a2f7888fe2e86dc35919733ba0933177.jpg

The fossil appears to be a 3 dimensional solid, as bits of the muddy layer fell away from the pictured edge, indicating to me a boundary. This is also the only edge exposed. It does look like it could have been musalagenous, but I may just be imposing my own bias. In hand it does look very biotic, but yet again, very subjective.IMG_20190706_230424987.thumb.jpg.dc39d602f69db3c220e293cf23b35677.jpg

I think you are describing a fossiliferous lens, or something like it (not sure of the exact term). A chunk of sediment that was redeposited as a unit in some sort of event.

Does it have any implications if it is an allochem? Or that's just what happens? Any other details it would be helpful for me to check?
