Lawrenceburg, Indiana Day 2


Nimravis

Recommended Posts

Today on day 2, I  spent about  six hours in the on and off rain, near Lawrenceburg, Indiana collecting Ordovician fossils. 

 

I found numerous trilobite parts, but nothing complete.

Things that believe are parts of trilobites- "Isotelus" fragments.

These two pieces were on a very large block that was not feasible to try and move. I figured that I would try and get them out, but  unfortunately, I was not successful .

"Platystrophia"

Gastropods– Believe these to be "Cyclonema".

Looks like you made some excellent finds. Those nautiloid pieces are by far my favorites. Congratulations and thanks for posting.

More great finds. Lots of Isotelus fragments, including a nice hypostome. The nautiloids are awesome.

Those were my favorites also, with the rain and cloud cover, they really popped out.

Whatever it is it looks like a pretty cool find.

Yes it is Kim..

That is pretty awesome then! All I ever find of baucalites around here are these little 1-3 cm phosphatized fragments in the North Sulfur River.

Although now that I think about it. I may have some tiny ones that I found at Lost Creek Dam. I thought they looked a tad like flattened crinoid stems, but now that I think about it, they may be a very small cephalopod. I had crinoid stems too though.

I’d love to see a pic once it’s washed off. I’m very curious about what it looks like under the mud.

I agree about the nautiloids - they're awesome!!!  And you have one really big one - much bigger than I'm used to finding around here (although a large one, Endoceras proteiforme, is supposed to be in the rocks around me - I just need to find one...).  Do you know the genus/species of the big one that you found?

 

Thanks for sharing!

@deutscheben thanks.

 

@KimTexan here is a pic of it cleaned up, but as you can see, there is a lot of other matrix attached.

 

@Monica I do not know, but checking around it looks like it could be one of two species; "Cameroceras inaequabile", which is a larger one or "Treptoceras duceri". I am leaning towards "Cameroceras" and the second pic below a"Treptoceras". I hope someone on the Forum and help with the ID.

Yours are pretty good size. What I found out at the Lost Creek Dam site, which is Pennsylvanian, were pretty small. At first I thought they were crinoid stems that got flattened. They had mud on them. Once I got them home I realized they must be something else.

There are 3 pieces that are different and I think a different genus.

The fragments are maybe 2 cm and under.

I think the shells I circled are Orthorhynchula, not Vinlandostrophia (what Platystrophia was renamed to in 2000).  Note the more rounded shape compared to the rectangular outline of Vinlandostrophia. Orthorhynchula are fairly common in the Fairmont formation which is where I believe you were collecting.

Thank you very much as I was trying an educated guess lol
