Shimmeron Posted July 4, 2018 Share Posted July 4, 2018 (edited) These are obviously fossils (from Tooele County Ut) but what on Earth are they and how were these formed? My best guess, worm tubes of some kind. I'm an environmental scientist (not a paleontologist or geologist) so making a positive ID is challenging. I've collected rocks & minerals for years and along with whats in my yard I've been trying to post the ones I've collected over the years that have fossilized characteristics. These ones certainly fit the bill and I seem to have 6-7 of these rocks. These also have florescent elements when I place them under UV light, with florescent blues, greens, orange and even some yellows. The rocks are covered in florescent lichens & cliches. The soil where I live is rich in colorful cliche deposits and lichen cover many of the rocks since I live near the benches of Tooele around 5,350 feet.

DPS Ammonite Posted July 4, 2018 Share Posted July 4, 2018 This looks like Syringopora coral. Do you know the name, age of the rock layer and its locality? The coral looks silicified and is probably in limestone. See this thread with a picture of my Syringopora coral: http://www.thefossilforum.com/index.php?/topic/85795-i-am-not-sure-what-this-is-maybe-bryozoan/&tab=comments#comment-924324 3 My goal is to leave no stone or fossil unturned. See my Arizona Paleontology Guide link The best single resource for Arizona paleontology anywhere. Link to comment Share on other sites More sharing options...
Shimmeron Posted July 4, 2018 Author Share Posted July 4, 2018 (edited) I live in Tooele County (Utah) on what use to be the ancient Bonneville Sea basin. The person who owned my home before I bought it collected rocks and minerals from this area and left them all over my property. Edited July 4, 2018 by Shimmeron Forgot to put the state.

Closest bedrock is Mississippian according to geo map. “...whilst this planet has gone cycling on according to the fixed law of gravity, from so simple a beginning endless forms most beautiful and most wonderful have been and are being evolved.” ~ Charles Darwin Happy hunting, Mason Link to comment Share on other sites More sharing options...
