Mahnmut Posted December 28, 2022 Share Posted December 28, 2022 (edited) Hello Melis and welcome to the forum! Sorry to say that I am quite sure this is no fossil head or skull, although I do see the resemblance in overall shape. The detail does not fit. Not sure from the fotos if the holes are fossils of other things like mollusks, or if there is a modern mollusk attached to it (middle of first 2 pics?) As far as the internet could tell me quickly, most old fossils from Minnesota are marine like sponges, bryozoa and such. And there are mammals (much younger) like your state fossil, the giant beaver, which I would expect to be typically preserved in a less "rocky looking" way.

Ludwigia Posted December 28, 2022 Share Posted December 28, 2022 One of the first things to look for when trying to recognize whether something is a fossil or not, is the substance and not necessarily the shape. There is no sign of bone on this rock. It just has a suggestive shape. The substance is mineralogical, probably mostly either quartz or calcite. Even if a skull bone happened to be replaced by a mineral such as quartz, it would retain its structure, and no such structures are visible on your stone. Greetings from the Lake of Constance.

Fossildude19 Posted December 28, 2022 Share Posted December 28, 2022 Welcome to the Forum. Unfortunately, I must agree with the others here. This looks like a piece of weathered limestone, with some potential marine fossils embedded within it. Close up pictures of some of the shell - looking areas may tell us more.

I don't think that's necessary, since all the photos can be enlarged and one can see the fine details quite well. Therefore I'm sticking with my purely mineral diagnosis.

Looking at the larger images on my computer rather than phone, I can see it is definitely some sort of quartz, chert, or calcite. 1 Tim - VETERAN SHALE SPLITTER VFOTM --- APRIL - 2015 __________________________________________________ "In every walk with nature one receives far more than he seeks."

Ludwigia Posted December 30, 2022 Share Posted December 30, 2022 So do we get some kind of response or are you just going to leave it at that? Greetings from the Lake of Constance. Roger http://www.steinkern.de/ Link to comment Share on other sites More sharing options...
