PaleoWilliam Posted December 19, 2015 Share Posted December 19, 2015 (edited) I was told these are worm tubes. They are polished. Edited December 19, 2015 by PaleoWilliam Link to comment Share on other sites More sharing options...
Auspex Posted December 19, 2015 Share Posted December 19, 2015 The shell looks like aragonite; these would then be baculites.

Herb Posted December 19, 2015 Share Posted December 19, 2015 Looks like a Baculite to me also.

abyssunder Posted December 19, 2015 Share Posted December 19, 2015 I agree.The conical shape, the iridescence and the ornamentation of the external shell, also the suture lines (as I think I see) makes me think they are Baculites fragments, not infilled tubes of tube worms. The iridescent color is due to the diffraction of light on the Aragonite layers.

FossilDAWG Posted December 19, 2015 Share Posted December 19, 2015 Where are these from, and how large (or small) are they? I agree they don't look like worm tubes, the aragonitic shell suggests a straight ammonite. Baculites is the most common example, but Sciponoceras gracile (formerly called a Baculites) is abundant in the Britton and other Cenomanian formations.

PaleoWilliam Posted December 19, 2015 Author Share Posted December 19, 2015 It was found in the NSR. Thanks for the help! Link to comment Share on other sites More sharing options...
FossilDAWG Posted December 21, 2015 Share Posted December 21, 2015 Baculites is common on the North Sulphur River. The bedrock is younger than the Sciponoceras zone so that genus would bot be found there. Don 1 Link to comment Share on other sites More sharing options...
