HVEMND Posted November 2, 2020 Share Posted November 2, 2020 (edited) I live in Central Wisconsin and have been finding several interesting looking rocks in scattered among landscaping in a parking lot. Here's one of the stranger ones. Total length is about 7 cm. Detail shot is of bottom of specimen. I've also made a 3d scan and uploaded to Sketchfab. I can provide more pictures by request. Thank you for your time! Edited November 2, 2020 by HVEMND Link to comment Share on other sites More sharing options...
Fossildude19 Posted November 2, 2020 Share Posted November 2, 2020 Welcome to the Forum. Sorry, but I am seeing a rock here. No bilateral symmetry, no bone texture, no scale morphology. 2 Tim - VETERAN SHALE SPLITTER VFOTM --- APRIL - 2015 __________________________________________________ "In every walk with nature one receives far more than he seeks."

Plax Posted November 2, 2020 Share Posted November 2, 2020 Chertified bryozoan? to me but has nothing to do with the shape. Not sure chertified is a word but silicified doesn't seem to work as well. 1 Link to comment Share on other sites More sharing options...
Troodon Posted November 2, 2020 Share Posted November 2, 2020 Gotta love that left view looks like a skull...a keeper but its NOT a skull Link to comment Share on other sites More sharing options...
Rockwood Posted November 2, 2020 Share Posted November 2, 2020 I think bryozoans are better builders, and it's not plumbed right to be bone. So until a better explanation comes along rock sounds like it. 1 Link to comment Share on other sites More sharing options...
HVEMND Posted November 2, 2020 Author Share Posted November 2, 2020 Thanks for the replys! I realize the top view is at a pretty bad angle and you can't really see any bilateral symmetry, here are some different frontal views that exhibit it a bit more. Kind of hard to do it justice with pictures. First two images are looking straight on about halfway down the length of specimen, third image is lower frontal view. I have some microsopy images too I'll get together Link to comment Share on other sites More sharing options...
LabRatKing Posted November 3, 2020 Share Posted November 3, 2020 I only see quartzite. I bet this one will give some niece piezoelectric flashes when struck against the same. 2 Link to comment Share on other sites More sharing options...
JohnJ Posted November 3, 2020 Share Posted November 3, 2020 Your images are very good. Landscaping rocks and gravels are typically chosen for their resistance to erosion. It doesn't work out well if those stones weather away in a few years. Thus, most landscaping gravel is comprised of quartz based rocks. Your piece has all the characteristics of just that...a piece of botryoidal quartz / chalcedony. 4 The human mind has the ability to believe anything is true. - JJ Link to comment Share on other sites More sharing options...
val horn Posted November 3, 2020 Share Posted November 3, 2020 I was going along saying rock rock rock until you showed the bottom field. I have no idea, the possibility of bryozoan is interesting, an inpression of coral perhaps roughly similar to what I picture below. I really dont know what it is, but I would be keeping it. What do you know of the orgin of these landscaping stones. Link to comment Share on other sites More sharing options...
Rockwood Posted November 3, 2020 Share Posted November 3, 2020 I considered pleurodictyum, but if it was too much information has been lost to be certain of it in my opinion. 1 Link to comment Share on other sites More sharing options...

I think that you may very well correct. Looking at the picture from wikipedia his fossil looks like a mold down to the "braided cord pattern around the base of each projection. 1 Link to comment Share on other sites More sharing options...

Coral is often preserved in a shallow window where less mobile minerals were able to penetrate. They can weather out looking distinct from the matrix that deeper or shallower layers are lost to.

Rockwood Posted November 3, 2020 Share Posted November 3, 2020 I guess a simpler explanation would be that the very end of the colony is all that broke off. Link to comment Share on other sites More sharing options...

HVEMND Posted December 2, 2020 Author Share Posted December 2, 2020 (edited) Sorry for the late response and thanks for the info! I'm going to upload some of the other rocks I've found so to differentiate the last will be Specimen 0. This will be specimen 1.
