Fingerprint Like Rock

Recommended Posts

Tyler Matters

I have a little rock, smaller than a marble. It looks like a fingerprint on a rock. Any ideas what it is? That's a marble for size comparison.

You are likely going to need to post closer up pictures.

I tried, but my phone wouldn't focus on something that small.

Please try and use a ruler in your photos, objects are not the same all over the world, marbles come in different sizes.

Where was it found? This will point to how old it is.

As the photo is dark I am only guessing due to the shape it could be a nummulites.

Looking forward to more pics.

Prasapora bryozoan??? They occur frequently in North East Iowa where the Ordovician rock is exposed. Not sure where in Iowa this was found. Will help in ID if you can tell what county at least.

Marbles are pretty standard size, but here is one of the front and one of the back with a ruler. It's a little over a centimeter long.

I see you have difficulties using the back camera of your zte z837vl smartphone, especially in focusing the objects.

Here's an online manual for your phone, check page 108.

 

Hope this helps. :)

 

(According to the last pictures, it can be anything, even an echinoderm, like cystoid or other.)
