Aninram Posted September 8, 2019 Share Posted September 8, 2019 Hello. These two specimens were discovered in Southern Indiana in a wooded area with a nearby spring. A tentative ID was given as a Rugosa (horn) coral but someone else thought it could be petrified wood. If it is a horn coral then are these two pieces from a mid-section hence whey the conical property is not apparent? I appreciate any and all feedback.

Mark Kmiecik Posted September 8, 2019 Share Posted September 8, 2019 Rugose coral is correct. Very nice specimens. Not big, but well preserved and showing cross-sectional detail. The reddish tint is due to iron-rich minerals in the immediate area. 1 Mark. Fossil hunting is easy -- they don't run away when you shoot at them!

Rockwood Posted September 8, 2019 Share Posted September 8, 2019 Agreed. Looks like bits of a colonial form. Link to comment Share on other sites More sharing options...
