sixgill pete Posted December 17, 2011 Share Posted December 17, 2011 I am not sure of what it is, but it does not look like coprolite to me. At least it does not look like what we find here.

AiyanaCaposewa Posted December 17, 2011 Author Share Posted December 17, 2011 Your probably right I am only a novice ..I will post a pic of the other coprolite I have ..although it is much smaller....thanks for the imput I am humbled to all the seriously amazing mentors on here Link to comment Share on other sites More sharing options...
Texas-Tunnel Rat Posted December 17, 2011 Share Posted December 17, 2011 Yeah looks inorganic like iron residue on rock Closest thing I can come up with are corprolites that are simular are that assocated with crustacea. But those are usally going to be fuzzier in texture.

The brain is trained to recognize shapes and associate them with familiar objects. The illusion of something that is familiar to us. Most of us (myself included) remember finding a fossil with a familiar shape and later have discovered the shapes were something different than our mental image of what the shapes might represent. This is the reason why many, new to the hobby, believe they have found a fossil egg because the object is round and smooth. The brain can only register the object as a round nodule or concretion...when images are available for comparison In this case, you have seen coprolite before and the shapes on the matrix are familiar. In my case...I can't count the number of times my eyes have tricked my brain into thinking I found something different than what I actually found Edited December 18, 2011 by Indy Flash from the Past (Show Us Your Fossils)MAPS Fossil Show Link to comment Share on other sites More sharing options...

Indy Posted December 18, 2011 Share Posted December 18, 2011 So what are your thoughts Indy Well, wish I had the matrix in hand...but based on what I see, I'm leaning towards what Texas Tunnel Rat suggested..."looks inorganic like iron residue on rock?

AiyanaCaposewa Posted December 18, 2011 Author Share Posted December 18, 2011 It has two different sides completely which side are you refering to ?? The first side is of a mustard in color and the other side is a dark red Link to comment Share on other sites More sharing options...
Indy Posted December 18, 2011 Share Posted December 18, 2011 It has two different sides completely which side are you refering to ?? The first side is of a mustard in color and the other side is a dark red Sorry, I just don't see fossil. Mustard and reddish colors are often indicators of iron oxidation...I'm really not an authority on minerals...But I don't see fossil. Showing the matrix to members of your fossil club or those at a local gem/mineral rock shops...They might be able to shed some light on what you have found. Mysteries can be fun, but if not answered they can be exasperating. Flash from the Past (Show Us Your Fossils)MAPS Fossil Show Link to comment Share on other sites More sharing options...

LoneRanger Posted December 18, 2011 Share Posted December 18, 2011 Based on the colors I see -- brown, mustard, reddish brown -- I would tend to agree with those who think these are iron oxide concretions. If the rock feels very heavy, this would be another clue that it's an iron oxide pseudo-fossil. Here's a link to Wikipedia's discussion of concretions: http://en.wikipedia.org/wiki/Concretion Link to comment Share on other sites More sharing options...

Auspex Posted December 18, 2011 Share Posted December 18, 2011 The "lumpy mass" looks more like coprolite that a "plate with lumps on it". <Not offering a diagnosis, just an observation> "There has been an alarming increase in the number of things I know nothing about." - Ashleigh Ellwood Brilliant “Try to learn something about everything and everything about something.” - Thomas Henry Huxley >Paleontology is an evolving science. >May your wonders never cease!

Rockwood Posted December 18, 2011 Share Posted December 18, 2011 (edited) So what do you think it is Rockwood??? Realistically, on this one, I find it hard to argue with the iron oxide concretion ID. As a general concept I'm more of an agnostic when it comes to coprolite IDs though. The bottom line is that the burden of proof is always on the side of the person claiming fossil. The latest pic. just came up. Those I would have trouble dismissing. I have something similar that has been called a concretion though. That is why I chose an agnostic outlook I guess.
