3 Bump Rock

Just tap to make larger :)

Galena, posser or prosser, I forget :), ordovician, se minnesota January hunt.

I call this my 3 bump rock. I wish I knew how to do pointers, but since I don't I will try to describe what I am seeing :)

Look to the right and see the big bump? See the rings around it? What is this?

Now look to the bottom. Smoother bump. Maybe brach? Lots of brachs in this location.

Then look to the left on the edge in the middle. Elongated bump.

Any ideas? Guesses? Suggestions?

Bev :)

I use Photoscape to do that - free software found online - great tool.

I'm thinking internal molds of brachiopods, and maybe a pelecypod for the one with the rings?

Not sure. Interesting things though.

partial bellerophont internal mold for the big one (in my opinion) not seeing a cystoid in it. the other two look like internal molds of brachs.

the shell of the Bellerophont had uneven growth lines on it. post-2953-0-82170000-1359751351_thumb.jpg

Hi Bev,

Channeling my inner trilobite I'm seeing a possible pygidium for the 'ringed' specimen.

Attached for comparison is the morphology of pygidial terrace lines in asaphid trilobites.

So, here are closeups of that third large bump that is being speculated as a possible trilobite pygin or a bella?

I believe their are a couple crinoid parts on top :)

The big one looks like a trilobite segment to me also.

I was leaning towards clam, but the terrace lines/rings had me stumped and thinking trilo. After seeing more photos I agree with the trilobite pygidium. There's not enough detail left to determine what kind easily though. The most common suspect with terrace lines that got that large at this site is Isotelus, but Failleana is also a rare possibility.

I went hunting at two sites that day. The other one is what got me started... I was coming back from Preston on Hwy. 16, and I stopped at that first hill with the shale on the north. It could be from that one too... If that makes any difference at all. :)

Fascinating that trilos come in so many different body types! I can see why they fascinate you guys! :)

Anyway, I want to THANK every one who has attempted to help me out with these IDs. Especially Caleb. Thank you for your efforts on the 3 unknown ones and the pointers and explaination! I truly appreciate it!

Hey Bev, if you are using a PC doing pointers/arrows is easy. Open your pic in Paint then look at the top row of the tools. The arrows are right there just click the one you want then place on the pic. You can change colors and size easily.
