Hazelnut Posted November 12, 2014 Share Posted November 12, 2014 This was found in south east Idaho in an old glacer lake. Found on the surface level with shale and other rocks. Not sure if this is a rock or a fossil. Link to comment Share on other sites More sharing options...

rejd Posted November 13, 2014 Share Posted November 13, 2014 Hi and welcome to the forum. I agree with fossildude that this is simply a rock. A fossil hunter needs sharp eyes and a keen search image, a mental template that subconsciously evaluates everything he sees in his search for telltale clues. -Richard E.

Auspex Posted November 13, 2014 Share Posted November 13, 2014 But it is not a simple rock; It looks like it's been through a lot! Is this as you found it?

Sacha Posted November 13, 2014 Share Posted November 13, 2014 It looks similar to a slick & slide, which is a rock that was at the boundary of a moving fault line. From what you say about it's location, I'll guess a dislodged piece of bedrock which has been glacially shaved. Link to comment Share on other sites More sharing options...
tmaier Posted November 13, 2014 Share Posted November 13, 2014 Sorry, but I am only seeing a rock here. There are probably guys over in the Geology ID section who are saying "Sorry, it is just a fossil, I don't see a rock here." It is a geologically interesting piece. I have no explanation. Curious.

Hazelnut Posted November 13, 2014 Author Share Posted November 13, 2014 (edited) This is how I found it. I have been told it's not a rock or a gem... I had an archeologist look at it too. .. when I look up what I have been told it looks like, it never looks like the pictures? Any idea what other type of rock this may be?

tmaier Posted November 13, 2014 Share Posted November 13, 2014 What were you told that it is? what did you look up? It doesn't seem to be a fossil. I was just kidding in my post above. The first picture surface looks like it has been scraped flat by ice sheet motion. Link to comment Share on other sites More sharing options...
Herb Posted November 13, 2014 Share Posted November 13, 2014 It is an interesting rock. All fossils are rocks (unless they have not been replaced) but all rocks are not fossils.

Auspex Posted November 13, 2014 Share Posted November 13, 2014 Whoever told you that it's not a rock is wrong. Perhaps the suggestion was that it is not a discrete mineral?

painshill Posted November 13, 2014 Share Posted November 13, 2014 (edited) It looks to me like a piece of fractured clastic turbidite (also known as "rock" ) with a thick weathering crust. Look closely at the frond-like swirls in the middle picture. Those patterns are very typical of sedimentary rocks formed in that way (fluid movement of sediments). The basin to the north of the Snake River Plain ocupying a large part of Idaho is deeply filled with rock composed of sediments of that kind and the western part of the plain is a huge tectonic graben (rift valley) where the strata have been depressed by "downfaulting". That could easily explain the unusually flat surface. Those kinds of processes can produce completely straight breakage surfaces which are close to vertical compared to any horizontal bedding planes in the rock.

Herb Posted November 14, 2014 Share Posted November 14, 2014 these type of sediments are not all that uncommon.

tmaier Posted November 14, 2014 Share Posted November 14, 2014 these type of sediments are not all that uncommon. They are in Florida. My son mostly grew up in an area of Florida that is totally sand. When he would go on trips he was amazed that there were rocks everywhere, and wondered who put them there.

Herb Posted November 16, 2014 Share Posted November 16, 2014 (edited) That would certainly be uncommon in for Florida for sure.
