csum Posted March 25, 2018 Share Posted March 25, 2018 Hello all, I'm new to the forum and would like some help with this find please. Several times I have visited Hungry Hollow and upon breaking a rock open find a "worm-like brown mark." Sometimes there is dark brown soft material on the line as can be seen in the picture. Would someone please help in idenfiying what this is? Thanks Chuck Link to comment Share on other sites More sharing options...
GeschWhat Posted March 25, 2018 Share Posted March 25, 2018 First let me welcome you to the forum. It appears your camera focused on the scale rather than the rock. Would you mind trying to get a clearer photo? It could be you have some sort of a trace fossil.

Kane Posted March 25, 2018 Share Posted March 25, 2018 Welcome to the forum from another Londoner. Judging by the picture, looks to be pyritized worm trace in Widder shale. The brownish colour is completely oxidized iron. 1 ...How to Philosophize with a Hammer Link to comment Share on other sites More sharing options...
Malone Posted March 26, 2018 Share Posted March 26, 2018 I have found similar items. I always just assumed They were a worm/nematode but I have almost no knowledge of these things. Link to comment Share on other sites More sharing options...

One key concept is that most any body shape will leave a worm like trail when traveling through sediment though. Link to comment Share on other sites More sharing options...

When I say I don't know or it looks like another object I am not saying I know or it is that object. I thought the forum was for discussion of similar interests. Knowing something is assumed/ or theory is part of truth. Also many creatures do not leave a worm like trail. Link to comment Share on other sites More sharing options...
Malone Posted March 26, 2018 Share Posted March 26, 2018 I believe the surrounding matrix would be a key to understanding what an object is. The permiantation of minerals directly adjacent to the object in question would be a indicator of what the chemical composition was. Another key would be the known chemical behaviors or processes. Another key would be the chemical content of the environment during lithification. Another key would be the pressure during lithification. Another key would be the temperature during lithification. Sadly I am not an expert in any of these, but happily I am still free to comment on them and increase my knowledge in areas of interest. Link to comment Share on other sites More sharing options...

The comment was that traces like yours can seldom be assigned to a specific animal. Having almost no knowledge of these things is quite normal.

I have repeatedly learned it since participating in these forum discussions. My greatest hindrance to true knowledge is my assumptions. Link to comment Share on other sites More sharing options...

DevonianDigger Posted April 4, 2018 Share Posted April 4, 2018 Welcome from NY! Definitely a pyritized worm tube. We get roughly 3.4 billion of these at the Penn Dixie site, (roughly, lol). Jay A.

Can't definitely say it's a worm that made the tube though. Link to comment Share on other sites More sharing options...
Malone Posted April 4, 2018 Share Posted April 4, 2018 I find them in multiple shapes and sizes. Link to comment Share on other sites More sharing options...
Malone Posted April 4, 2018 Share Posted April 4, 2018 (edited) I showed one earlier on the forum and the guess was ghost shrimp burrow. Edited April 4, 2018 by Malone Grammatical error Link to comment Share on other sites More sharing options...
