MarqusandDad Posted May 3, 2014 Share Posted May 3, 2014 I was out on a little walk this morning as the clouds are finally gone. I found this in a pile of limestone being used to prep a new driveway so determining location is not possible. Any help with it will be appreciated, thank you. I am in Wisconsin southeast section and this is most likely from a local quarry. Is this something that would benefit from some prep work as I am just starting to practice.

Tennessees Pride Posted May 3, 2014 Share Posted May 3, 2014 That certainly is an unusual specimen.....i'll take a shot in the dark and say perhaps fossil algae.(?) --- Joshua tennesseespride@gmail.com Link to comment Share on other sites More sharing options...
Auspex Posted May 3, 2014 Share Posted May 3, 2014 I think the rock was accreted in layers, was water-tumbled, and chipped to show the alternating layers.

Tennessees Pride Posted May 3, 2014 Share Posted May 3, 2014 Here's a Cretaceous specimen i have thought "might" be fossil algae, but i guess i could very well be wrong about that. --- Joshua tennesseespride@gmail.com Link to comment Share on other sites More sharing options...

Tennessees Pride Posted May 3, 2014 Share Posted May 3, 2014 Here's a low quality pic of fossil algae from the net, it was about like something i was thinking of,but like i say, i'm not sure if either of our specimens are infact fossil algae. --- Joshua tennesseespride@gmail.com Link to comment Share on other sites More sharing options...
Tethys Posted May 3, 2014 Share Posted May 3, 2014 It looks like a piece of sandstone with liesegang patterns. Link to comment Share on other sites More sharing options...
MarqusandDad Posted May 3, 2014 Author Share Posted May 3, 2014 Thats darn close so for now I will go with Fossil Algae. I looked with my loupe and the layers are all around so it is not incased in matrix but rather well worn down. I am going out some more in a little while and hope to have some other things to show. Still looking for a trilobit in matrix I can practice prepping. Wish us luck.... Oh my son Marqus said you are about it being algae he said it so emphatically I had to laugh.

MarqusandDad Posted May 3, 2014 Author Share Posted May 3, 2014 Are liesegang patterns common in limestone? Link to comment Share on other sites More sharing options...
Tethys Posted May 3, 2014 Share Posted May 3, 2014 Are liesegang patterns common in limestone? Yes. Especially if there is a lot of iron in the groundwater. Link to comment Share on other sites More sharing options...

IMG_1702.JPG I'm still seeing somwhat of a semblance to fossil algae, but just can't be sure....lets see what the other's say. Tethys is pretty smart on botanicals, so i'm not sure i would favor my opinion over hers. --- Joshua tennesseespride@gmail.com Link to comment Share on other sites More sharing options...
MarqusandDad Posted May 3, 2014 Author Share Posted May 3, 2014 I sectioned this front and back about 1/8th inch off the front and about 1/4 inch off the back just to see if the pattern continued all the way through the sample. And as you can see it is different. Link to comment Share on other sites More sharing options...

MarqusandDad Posted May 3, 2014 Author Share Posted May 3, 2014 Yep me to but it is still cool looking and will be the start of my pseudo fossil collection. Link to comment Share on other sites More sharing options...
painshill Posted May 3, 2014 Share Posted May 3, 2014 Agree it's mineralogical. Those are dendrites in the final picture... a common depositional pattern for iron or manganese oxides in limestone when percolating groundwater is rich in either of those minerals.
