Jes Posted May 25, 2019 Share Posted May 25, 2019 HI I'm new to the forum, just looking for some help identifying this fossil. Found in Columbia MO. Thanks! Link to comment Share on other sites More sharing options...
Tidgy's Dad Posted May 25, 2019 Share Posted May 25, 2019 A solitary rugose 'horn' coral, I think. Hello, and a very warm welcome to TFF from Morocco. 2 Life's Good! Tortoise Friend. Link to comment Share on other sites More sharing options...
Rockwood Posted May 25, 2019 Share Posted May 25, 2019 Can we see an end ? I'm not so sure about the coral idea. Link to comment Share on other sites More sharing options...

Fossildude19 Posted May 25, 2019 Share Posted May 25, 2019 These may help, or confuse the issue further.

Mark Kmiecik Posted May 25, 2019 Share Posted May 25, 2019 I have no clue. It says flora and fauna at the same time. Whatever it is, it's a great specimen! Mark. Fossil hunting is easy -- they don't run away when you shoot at them! Link to comment Share on other sites More sharing options...
TqB Posted May 25, 2019 Share Posted May 25, 2019 I'm strongly leaning towards weathered rugose coral, something with a structure similar to Amplexus. This has a simple structure of septa and horizontal cupped tabulae. A good closeup might settle it. A fine specimen! An accurate old plate (I have a specimen but not nearly so clear) - the tabulae (if that's what they are) are further apart in the OP's specimen: 2 Tarquin Link to comment Share on other sites More sharing options...
Mark Kmiecik Posted May 25, 2019 Share Posted May 25, 2019 That got me onto the coral wagon. Mark. Fossil hunting is easy -- they don't run away when you shoot at them! Link to comment Share on other sites More sharing options...
piranha Posted May 25, 2019 Share Posted May 25, 2019 The 'ribs' appear to have pointed terminations favoring a Calamites ID. A hi-res photo would certainly help. 2 Link to comment Share on other sites More sharing options...

This section seems to show possible coral epitheca/tabulae edges, with a cup-in-cup structure. Can Calamites look like that? 1 Tarquin Link to comment Share on other sites More sharing options...
Jackson g Posted May 26, 2019 Share Posted May 26, 2019 Looks like caninia torquia coral. Not sure, I've found some similar. 3 Link to comment Share on other sites More sharing options...

TqB Posted May 26, 2019 Share Posted May 26, 2019 I think it may be showing thin minor septa in places (i.e. the second order septa, between the major ones). I'll stop looking now, pending a better pic if possible. As in this Caninia: Tarquin Link to comment Share on other sites More sharing options...

I'm thinking the segments are too irregular and too compressed to be calamites, although calamites is the first thing that came to mind when I saw the photo. Mark.
