New Members MarkH Posted December 3, 2023 New Members Share Posted December 3, 2023 I am looking for someone or an expert that could help me identify some fossilized coral outcrops that are on my property near fort stockton texas. These fossilize coral go at least four to five feet under the ground. The coral formations are about four feet under the ground except for the outcrop areas. However there are at least 30 of these outcrop areas over the fifty acres I own. Thanks for any suggestions on what these are or a recommended expert to help me.

Darktooth Posted December 3, 2023 Share Posted December 3, 2023 Hello, and welcome to the forum. From what I can see from the pictures these look like some type of burrows and not coral. Please take some close-up pics. 2 I like Trilo-butts and I cannot lie. Link to comment Share on other sites More sharing options...
TqB Posted December 3, 2023 Share Posted December 3, 2023 I'm wondering if this could be calcareous tufa. Closeups should help. Tarquin Link to comment Share on other sites More sharing options...

FranzBernhard Posted December 3, 2023 Share Posted December 3, 2023 (edited) Tufa or rhizolite. Can these two grade into each other? Edit: Or a deposit around something man-made? The interior is really regular and smooth. Franz Bernhard Edited December 3, 2023 by FranzBernhard 1 Link to comment Share on other sites More sharing options...
New Members MarkH Posted December 3, 2023 Author New Members Share Posted December 3, 2023 Here are some of the smaller rocks that have broken off the main sets of rocks found in the first pictures. The Land these are coming from is where the old Comanche springs would end and flood about 35 acres. Link to comment Share on other sites More sharing options...

New Members MarkH Posted December 3, 2023 Author New Members Share Posted December 3, 2023 Franz Are there any books or articles that I can read to learn about these mineral deposits? Some of these deposits are extremely small then go up to 1000 lbs. Any help would be appreciated Link to comment Share on other sites More sharing options...

I don´t know of any books about that subject, but such tufa formations are quite widespread, but always rather localized with a few exceptions, and there should be something around. Tufa - Wikipedia Any helpful reference in this article? Here in my area, some tufa was very localy used as building stone (as long as the minor supply lasted!) and I have found the lid of a washing machine in a small creek, thickly (dm) coated in tufa...
